Hidrologia de encosta numa cabeceira de drenagem com cobertura de eucalipto na bacia do rio Sesmarias: médio vale do rio Paraíba do Sul
Provedor de dados: 25
Autores: Sato, Anderson Mululo; Avelar, André de Souza; Coelho Netto, Ana Luiza.
Since early 21 century the landscape mosaic of middle Paraíba do Sul river valley has been rapidly modified by spreading of Eucalyptus patches in substitution to cattle grazing grasslands. On the other hand, the region have evidences of geomorphological instability due to occurrence of deep gullies caused by groundwater flows and landslide scars. Our current research interests are driven to understand the role played by Eucalyptus controlling the hillslope hydrology and explain how these changes may affect the regional landscape system. This paper presents the hydrological results in the headwater zone of a first order drainage basin in response to biota-soil-water interactions.

Uso do território pelo circuito espacial produtivo de celulose em Eunápolis, sul da Bahia
Provedor de dados: 25
Autores: Joly, Carolina.
This study analyses the insertion of the spatial productive circuit of cellulose in Eunápolis, in the extreme south of Bahia state, with the installation of the Veracel Celulose enterprise. Result of a joint venture between Aracruz Celulose and Stora Enso, Veracel Celulose is one of the largest industrial plants of this world circuit. The research shows that land concentration increase, caused by the intensive land purchasing carried out by the company, and the large contingent of migrants attracted to Eunápolis, are not compensated by jobs offered and tributes paid by Veracel. So, this large cellulose venture brought little social and economic gains for people living in the region. As a conclusion, the regional development speech still do not consider the...

Provedor de dados: 25
Autores: Almeida, Julio Cesar Raposo de; Laclau, Jean-Paul; Gonçalves, José Leonardo de Moraes; Moreira, Rildo Moreira e; Rojas, Juan Sinforiano Delgado.
Leaf Area Index (LAI, i.e. horizontal projection of leaf area per unit ground area) is highly correlated with water balance and net primary production in forest ecosystems. LAI is related with species, but it is also highly dependent on environmental conditions and management practices which influence the availability of water and nutrients. This work aimed at establishing allometric relationships in fast-growing Eucalyptus grandis plantations in Brazil (Itatinga – São Paulo) making it possible to predict the LAI under K and Na fertilization. Dendrometric inventories (Crown diameter – CD, Diameter at Breast Height - DBH and total height - H) were made at 5, 8, 11, 24 and 35 months after planting. The trees were divided into 8 crown index (CI) or basal area...

Análise do tamanho e distância entre fragmentos florestais na bacia hidrográfica do Rio Una
Provedor de dados: 25
Autores: Catelani, Celso de Souza; Batista, Getulio Teixeira.
This article characterized the forest fragments of Una River hydrographic basin, affluent of the Paraíba do Sul River. Results showed that the average mean size of all fragments is 9.06 ha and that the correlation to the circular shape is 0.68 and the mean nucleus area of fragments considering a border effect of 60m is 5.86 ha. The mean distance among them is 245m. These parameters indicate that this basin has elongated fragments, with high border effect and may be in risk of biodiversity erosion. The image showing the different size classes of fragments allowed spatial observation of critical areas of the basin in ecological sustainability risk. The computing tools proved to be useful and easy to use as long as a previous georeferenced data basis is...

VAZÃO DE PROJETO EM BACIAS HIDROGRÁFICAS RURAIS COM ÁREAS EM DECLIVE
Provedor de dados: 25
Autores: Targa, Marcelo Santos.
A determinação de vazões de projeto em bacias hidrográficas rurais com áreas em declive torna-se difícil pela pequena disponibilidade de dados de vazão, provenientes de monitoramentos e medições, para a maioria das bacias. Dessa forma a obtenção dessas vazões são, freqüentemente, baseadas em dados de chuvas. No presente trabalho procurou-se demonstrar a aplicação da fórmula Racional e da Curva Número, para determinação da vazão máxima de projeto em bacias hidrográficas essencialmente rurais. Essas metodologias foram desenvolvidas para as condições dos estados Unidos da América e embora, sejam consideradas consagradas por apresentarem resultados bastante satisfatórios, sua aplicação no Brasil deve ser feita com bastante critério.

The importance of the water in the current geo-political context turns it into a research theme that focuses on conserving its quality and improving its use conditions in certain systems. The hidrologic cycle consists of water exchanges among rivers, lakes, and oceans, as well as atmosphere and soil. The species of the gender eucalyptus possess a very fast growth rate in relation to native species, what causes a large demand for water, even though their water use efficiency is better. As well as any vegetable species, the eucalyptus uses water to satisfy their physiologic demands, promoting its growth. As a result eucalyptus promotes reduction in the flow of water in watercourses. Areas covered with forest plantations, besides improving the landscape as a...

Autores: Pinto, Fábio de Assis.
No Brasil, o ácaro ectoparasita de abelhas Varroa destructor Anderson e Trueman (Acari: Varroidae) se mantém em índices de infestação baixos, não causando grandes prejuízos. Todavia com a introdução e possível predominância de um novo haplótipo (K) do ácaro, geralmente encontrado em regiões com altas taxas de infestação (TI), faz-se necessário o monitoramento e seleção de colônias resistentes à praga, evitando problemas futuros. Vários fatores são relacionados como possíveis responsáveis pela dinâmica de infestação do ácaro, dentre os quais se destaca o comportamento higiênico (CH). Nesse contexto buscamos avaliar o CH de abelhas africanizadas Apis mellifera L. (Hymenoptera: Apidae) correlacionando com as TI do ácaro em apiários de dois municípios do...

A produção mineral pode ser sustentável? Uma análise epistemológica da questão
Provedor de dados: 25
Autores: Lima, Flavio Jorge; Fortes Neto, Paulo; Batista, Getulio Teixeira.
A bibliografia estudada para discutir a sustentabilidade da produção mineral aponta para duas correntes que debatem o assunto, caracterizadas de acordo com o ponto central das teses: a dos recursos fixos e custos oportunidades. A primeira encara os recursos explorados pela mineração como não renováveis e passíveis de exaustão. A segunda indica que novas tecnologias suprirão as demandas futuras à medida que os recursos poderão ser extraídos de fontes com menor concentração de minérios. Ambas pressupõem que o Estado poderia interferir incisivamente na questão da internalização dos custos da produção e da recuperação dos impactos ambientais. Legalmente, o Estado instituiu o principio “poluidor-pagador”, que parece não atender efetivamente a demanda degradante...

RESUMO - O Rio Una recebe grande aporte de sedimentos provindos de margens erodidas, obras mal planejadas e vastas áreas de pastagem degradada, os quais transportam um grande volume de sedimentos para o Rio Paraíba do Sul, inviabilizando o uso dessas águas para o abastecimento urbano. A criação do banco de dados ambientais da bacia Una (com 476 km²) é importante pela grande quantidade de vertentes naturais (com alto potencial de produção de água) e pela crescente perda de qualidade pelo aumento da carga de sedimentos. A estruturação do banco georreferenciado envolveu: geração de um mosaico ortorretificado com resolução de 0,60 m; mapeamento de uso do solo na escala 1:25.000; rede de drenagem e malha viária na escala 1:10.000; geração de um MDE; mapeamento...

As atividades antrópicas sobre os ecossistemas, como a agricultura mecanizada, o predomínio das monoculturas e o uso de extensas pastagens, têm contribuído para a degradação dos solos, como consequência do uso intensivo e inadequado dos ambientes naturais. O conhecimento dos processos responsáveis por alterações ambientais, principalmente o manejo incorreto da terra, é essencial para obtenção de sistemas de produção agropecuária sustentáveis. Os impactos ambientais provocados pelos agrossistemas podem ser avaliados pelo estabelecimento e monitoramento de indicadores físicos, químicos e biológicos dos solos. Mudanças no modelo do agronegócio podem contribuir para a sustentabilidade dos sistemas naturais.

Resumo. O processo histórico de ocupação e transformação do espaço geográfico na região sudeste do Brasil, numa área denominada Alto Vale do Paraíba no Estado de São Paulo, deixou como legado um modelo de uso da terra baseado no desmatamento e na fragmentação florestal. Atualmente essa fragmentação está aumentando numa curva crescente e contínua devido aos efeitos do crescimento populacional dos centros regionais próximos. Isso fomenta o aumento da procura por propriedades situadas na zona rural e, conseqüentemente, geram pressões econômicas e especulação imobiliária que determinam significativas mudanças na distribuição fundiária da região. Vários estudos investigaram os efeitos da fragmentação florestal em regiões e áreas diferentes. Entretanto, esses...

Agricultura e sustentabilidade
Provedor de dados: 25
Autores: Ricci, Écio A.; Rezende Filho, Cyro de B.; Fortes Neto, Paulo; Batista, Getulio T.
A agricultura como atividade econômica tem início na Pré-história. Essencial para a sedentarização da humanidade se desenvolveu para suprir as necessidades de alimentos e fibras que eram coletados na natureza. No período da Expansão Colonial européia, a atividade tornou-se empresarial na forma de plantation. A partir daí, aliado às formas primitivas de práticas agrícolas a atividade passa a ter caráter predatório. Considerando esse fato, vários autores destacados neste artigo, discutem a agricultura praticada de forma sustentável. Por outro lado, a Agricultura Familiar tem sido estudada por Veiga (1996), Gomes (2004), Pereira (2009), Caetano (2010) e Vargas (2010). Similarmente, a Agricultura Comercial foi analisada por Assad e Almeida (2004), Santos...

Autores: Mendes, Carlos André Bulhões; Lima, Walter de Paula.
this paper intends to give general guidelines for the environmental impact analysis of planted forest projects, specifically related to their hydrological impacts. These possible impacts are not inherent to the plantations themselves, but depend on the interactions of the plantations with the prevailing environmental conditions. In this regard, the impacts could occur at different intensities, but, for the same reason, they can also be minimized by the adoption of management strategies that consider the potentialities and limitations of the physical environment. Because of that, it is argued that the adoption of catchments as the basic unit for the planning and implementation of planted forest management is a consistent strategy that naturally takes into...

Provedor de dados: 18
Autores: Wortmann, C.S.; Tarkalson, D.D.; Shapiro, C.A.; Dobermann, A.R.; Ferguson, R.B.; Hergert, G.W.; Walters, D.T.
Nitrogen use efficiency (NUE) is of economic and environmental importance.  Components of NUE were evaluated in 32 irrigated corn (Zea mays L.) trials conducted across Nebraska with different N rates and where the previous crop was either corn (CC), drybean  (Phaseolus vulgaris L.) (CD), or soybean (Glycine max L.) (CS).  The mean grain yield with adequate nutrient availability was 14.7 Mg ha–1 .  When no N was applied, measured soil properties and irrigation water N accounted for &lt;20% of the variation in plant N  uptake (UN).  Mean fertilizer N recovery in above-ground biomass was 74% at the lowest N rate compared with 40% at the highest N rate, a mean of 64% at the economically optimal N rate (EONR), and least with CD.  Agronomic efficiency of...

Qualitative and quantitative methodologies for determination of airborne microorganisms at concentrated animal-feeding operations
Provedor de dados: 18
Autores: Dungan, R.S.; Leytem, A.B.
The generation of airborne microorganisms  from concentrated animal-feeding operations (CAFOs) is a  concern from a human and animal health perspective. To  better understand the airborne microorganisms found in  these environments, a number of collection and analytical  techniques have been utilized and will be discussed in this  review. The most commonly used bioaerosol collection  method is the liquid impingement format, which is suitable  with a number of culture-based and non-culture molecularbased  approaches, such as polymerase chain reaction.  However, the vast majority of airborne microorganism  studies conducted at CAFOs utilize culture-based analyses.  Because of the limitations often associated with culturebased  analyses, we focused our...

Effect of Growth Promotants on the Occurrence of Endogenous and Synthetic Steroid Hormones on Feedlot Soils and in Runoff from Beef Cattle Feeding Operations
Provedor de dados: 18
Autores: BARTELT-HUNT L, SHANNON; SNOW D, DANIEL; KRANZ L, WILLIAM; MADER L, TERRY; Shapiro, C.A.; VAN DONK J, SIMON; SHELTON P, DAVID; Tarkalson, D.D.
Supplements and growth promotants containing steroid hormones are routinely administered to beef cattle to improve feeding efficiency, reduce behavioral problems, and enhance production.  As a result, beef cattle manure will contain both synthetic steroids as well as a range of endogenous steroids including androgens, estrogens, and progestogens.  A two-year controlled study was conducted in which beef cattle were administered steroid hormones via subcutaneous implants and feed additives and the occurrence of sixteen endogenous and synthetic steroid hormones and metabolites was evaluated in runoff from beef cattle feedlots and in manure and soil collected from feedlot surfaces. Samples were extracted and analyzed using liquid chromatography tandem mass...

Interaction of calcium and phytate in broiler diets: 2. Effects on total and soluble phosphorus excretion
Provedor de dados: 18
Autores: Leytem, A.B.; Plumstead, P.W.; Maguire, R.O.; Kwanyuen, P.; Burton, J.W.; Brake, J.
Dietary Ca has been reported to influence the amount of phytate excreted from broilers and affect the solubility of P in excreta. To address the effects of dietary Ca and phytate on P excretion, 12 dietary treatments were fed to broilers from 16 to 21 d of age. Treatments consisted of 3 levels of phytate P (0.10, 0.24, and 0.28%) and 4 levels of Ca (0.47, 0.70, 0.93, and 1.16%) in a randomized complete block design. Feed phytate concentrations were varied by formulating diets with 3 different soybean meals (SBM): a low-phytate SBM, a commercial SBM, and a high phytate Prolina SBM having phytate P concentrations of 0.15 to 0.51%. Fresh excreta was collected from cages during 2 separate 24-h periods; collection I commenced after the start of dietary...

Physical Disintegration of Biochar: An Overlooked Process
Provedor de dados: 18
Autores: Spokas, K.A.; Novak, J.M.; Masiello, C.A.; Johnson, M.G.; Colosky, E.C.; Ippolito, J.A.; Trigo, C.
Data collected from both artificially and field (naturally) weathered biochar suggest that a potentially significant pathway of biochar disappearance is through physical breakdown of the biochar structure. Through scanning electron microscopy (SEM) we characterized this physical weathering which increased structural fractures and possessed higher numbers of liberated biochar fragments. This was hypothesized to be due to the graphitic sheet expansion accompanying water sorption coupled with comminution.  These fragments can be on the micro and nano-scale, but are still carbon-rich particles with no detectable alteration in the oxygen to carbon ratio of the original biochar. However, these particles are now easily dissolved and could be moved by...

Control of curly top in sugar beet with seed and foliar insecticides
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Wenninger, E.J.; Eujayl, Imad A.
Curly top in sugar beet is a serious problem that is caused by Beet curly top virus and other closely related species and transmitted by the beet leafhopper. In order to find a means of reducing curly top in sugar beet, 15 combinations of insecticide seed (Poncho, Poncho Beta, and Poncho Votivo) and foliar (Asana, Cyazypyr, Lorsban, Mustang,  Scorpion, and Sivanto) treatments were evaluated versus an untreated check during the 2012 and 2013 growing seasons. An epiphytotic was created by releasing viruliferous beet leafhoppers 58 to 59 days after planting. The foliar sprays were applied 6 to 7 days before and again 6 to 8 days after leafhopper release. Seed treatments (active ingredient:  clothianidin) were able to reduce symptoms by 26 to 42% and increase...

Carbon and nitrogen stable isotope ratios can estimate anionic polyacrylamide degradation in soil
Provedor de dados: 18
Autores: Entry, J.A.; Sojka, R.E.; Hicks, B.J.
Water-soluble anionic polyacrylamide (PAM) is applied to millions of hectares worldwide as a highly effective erosion-preventing and infiltration-enhancing polymer, when applied at rates of 1 to 2 kg ha? 1 (i.e., 1 to 10 g m? 3) in furrow water. PAM degradation has not directly been measured in soil. We tested the ability of stable isotopes of C and N at natural abundance to estimate PAM degradation rates. Values of ?13C were related to anionic PAM concentration in a positive curvilinear relationship in a low-C, low-N, Durinodic Xeric Haplocalcid (Portneuf series) soil. The other soils with higher organic C or N concentrations did not show significant relationships between PAM concentrations and ?13C values. The ?15N values were not related to anionic PAM...

Using Multiple Calibration Sets to Improve the Quantitative Accuracy of Partial Least Squares (PLS) Regression on Open-Path Fourier Transform Infrared (OP/FT-IR) Spectra of Ammonia over Wide Concentration Ranges
Provedor de dados: 18
Autores: Shao, Limin; Bianxia, Liu; Griffiths R, Peter; Leytem, A.B.
A technique of using multiple calibration sets in partial least squares regression (PLS) was proposed to improve the quantitative determination of ammonia from open-path Fourier transform infrared spectra.  The spectra were measured near animal farms, and the path-integrated concentration of ammonia fluctuated from nearly zero to a high of about 1000 ppm-m.  The PLS regression using a single calibration set over such a large concentration range had decreased quantitative accuracy due to the nonlinear relationship between concentration and absorbance.  In the PLS regression with multiple calibration sets, each calibration set accounted for a smaller concentration range, which significantly decreased the serious nonlinearity problem in PLS regression with a...

Effect of composting on the fate of steroids in beef cattle manure
Provedor de dados: 18
Autores: Bartlelt-Hunt, S.L.; De Vivo, S; Johnson, L.C.; Snow, D.D.; Kranz, W.L.; Mader, T.L.; Shapiro, C.A.; Van Donk, S.J.; Shelton, D.P.; Zhang, T.C.; Tarkalson, D.D.
In this study, the fate of steroid hormones in beef cattle manure composting is evaluated.  The fate of 16 steroids and metabolites was evaluated in composted manure from beef cattle administered growth promotants and from beef cattle with no steroid hormone implants.  The fate of estrogens (primary detected as estrone), androgens, progesterone, and the fusarium metabolite and implant a-zearalanol were monitored in manure compost piles.  First-order decay rates were calculated for steroid half-lives in compost and ranged from 8 days for androsterone to 69 days for 4-androsterone.  Other steroid concentration data did not fit first-order decay models which may indicate that other microbial processes may result in steroid production or synthesis in...

Autores: Alves, B.S.Q.; Dungan, R.S.; Carnin, R.L.P; Galvez, R.; de Carvalho Pinto, C.R.S.
While most waste molding foundry sands (WFSs) are not hazardous in nature, regulatory agencies are often reluctant to permit their beneficial use in agricultural and geotechnical applications due to concerns over metal leaching. The objective of this study was to quantify total and Toxicity Characteristic Leaching Procedure (TCLP) metals in 16 waste sands from Brazilian ferrous foundries and assess their potential to leach metals to groundwater using a probabilistic model developed by the U.S. EPA. Total and TCLP metal concentrations in the non-hazardous sands fell within ranges as reported in the literature, although some of the leachate concentrations were found to exceed drinking water and groundwater maximum contaminant levels MCLs. Leachate values...

Efficient recycling of abundant manure resources from regional dairy industries in the semiarid West requires a better understanding of N availability in manure-amended soils. We measured net N mineralization using buried bags, and crop biomass, N uptake, and yields for sprinkler-irrigated, whole (noneroded) and eroded Portneuf soils (coarse-silty, mixed, superactive, mesic Durinodic Xeric Haplocalcid) subject to a one-time manure application. Treatments included a control, fertilizer, two rates of composted dairy manure (28.4, 64.3 Mg ha–1, dry wt.), and two rates of stockpiled dairy manure (23.3, 45.7 Mg ha–1, dry wt.) applied in the fall before the Year 1 cropping season.

Surfactant and irrigation effects on wettable soils: runoff, erosion, and water retention responses
Provedor de dados: 18
Autores: Lehrsch, G.A.; Sojka, R.E.; Reed, J.L.; Henderson, R.A.; Kostka, S.J.
Surfactants are chemical compounds that change the contact angle of water on solid surfaces and are commonly used to increase infiltration into hydrophobic soil. Since production fields with water-repellent soil often contain areas of wettable soil, surfactants applied to such fields will likely be applied to wettable soil, with unknown consequences for irrigation-induced erosion, runoff, or soil water relations. We evaluated surfactant and simulated sprinkler irrigation effects on these responses for three wettable, Pacific Northwest soils, Latahco and Rad silt loams and Quincy sandy loam. We studied three surfactants: an alkyl polyglycoside in solution at a concentration of 18 g a.i./kg, a block copolymer at 26 g/kg, and a blend of the two at 43 g/kg....

Beet curly top resistance of USDA-ARS National Plant Germplasm System Plant Introductions, 2010
Provedor de dados: 18
Autores: Panella, Leonard W.; Strausbaugh, C.A.
Twenty-six wild beet (Beta vulgaris subsp. maritima (L.) Arcang) accessions from the Beta collection of the USDA-ARS National Plant Germplasm System were screened for resistance to Beet severe curly top virus (BSCTV) and other closely related Curtovirus species in 2010. The curly top evaluation was conducted at the USDA-ARS North Farm in Kimberly, ID which had been in beans in 2009.

Management of curly top in sugarbeet with seed and foliar insecticides
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Wenninger, E.J.; Eujayl, Imad A.
Curly top in sugarbeet can result in severe yield losses and is caused by Beet severe curly top virus (BSCTV) and other closely related Curtovirus spp. which are vectored by the beet leafhopper.  Neonicotinoid seed treatments (Cruiser, NipsIt, and Poncho) have been shown to be an effective supplement to host resistance, but measures to extend control beyond the duration of seed treatment efficacy needs to be investigated.  In 2012, a field study was arranged in a randomized complete block design with 8 replications and planted with the cultivar B-42.  The 16 treatments included untreated and Poncho Beta treated seed with and without 6 foliar insecticides (applied 7 days before and 6 days after release of viruliferous beet leafhopper) and just Poncho and...

Moving spray-plate center-pivot sprinkler rating index for assessing runoff potential
Provedor de dados: 18
Autores: King, B.A.
Numerous moving spray-plate center-pivot sprinklers are commercially available providing a range of drop size distributions and wetted diameters. A means to quantitatively compare sprinkler choices in regards to maximizing infiltration and minimizing runoff is currently lacking. The objective of this study was to develop a soil independent quantitative runoff potential index to facilitate selection of sprinklers for center-pivot sprinkler irrigation systems. Drop sizes, velocities and water application rates of numerous moving spray-plate sprinklers were measured in the laboratory over a range of flow rates and operating pressures. The proposed sprinkler runoff index is based on application rates of kinetic energy and water computed by overlapping specific...

Commercial sugar beet cultivars evaluated for rhizomania resistance and storability in Idaho, 2011
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Eujayl, Imad A.; Rearick, E.; Foote, P.
Rhizomania caused by Beet necrotic yellow vein virus (BNYVV) and storage losses are serious sugar beet production problems.  To identify sugar beet cultivars with resistance to BNYVV and evaluate storability, 31 commercial cultivars were screened by growing them in a sugar beet field infested with BNYVV in Kimberly, ID during the 2011 growing season in a randomized complete block design with 4 replications.  At harvest on 18 October 2011, roots were dug and evaluated for symptoms of rhizomania and also placed in an indoor commercial sugar beet storage building.  Storage samples were evaluated for fungal growth known to correlate with sucrose loss.  Depending on cultivar, surface root discoloration (rot and fungal growth) ranged from 1 to 14%.  Overall, the...

Provedor de dados: 18
Autores: Tarkalson, D.D.; Mikkelsen, R.L.
Recent efforts to reduce phosphorus (P) content of corn grain fed to poultry  have led to the development of low-phytic-acid corn. Research is needed to evaluate  the environmental impact of the application to cropland of manure from animals fed  low-phytic-acid corn. The purpose of this research was to determine P losses in  runoff from a bare Piedmont soil (cecil clay loam; clayey, kaolinitic, thermic, Typic  Kanhapludult) in the southeastern United States receiving surface applications of  broiler litter from birds fed a low-phytic-acid corn (HAP broiler litter). The HAP  litter was applied at rates of 0, 8, 16, 33, 49, 66, and 82 kg P ha-1  . Simulated  rainfall was applied at a rate of 7.6 cm hr-1 on the same day the litter sources were  applied to...

Reducing sucrose loss in sugarbeet storage
Provedor de dados: 18
Autores: Strausbaugh, C.A.
Controlling sucrose loss in sugarbeet  storage has been an industry  goal since the 1950s. Sugarbeet  roots utilize sucrose for energy to  maintain themselves.  Dessication from wind and sun or  too much rain and microbial activity  can negatively influence stored roots,  increasing respiration and the buildup  of impurities.  Factors such as scalping, impacts  and wounding during harvest and  transport, mud and weeds in piles, and  unusually high and low temperature  can also lead to sucrose loss.  Disease and drought stress during  production can also predispose roots  to sucrose loss in storage.  In particular, rhizomania caused  by Beet necrotic yellow vein virus  has been shown to compromise the  storability of roots allowing for significant   sucrose...

Improving Sugarbeet Storability
Provedor de dados: 18
Autores: Strausbaugh, C.A.
Storing sugarbeets, in piles, under ambient con-  ditions, in production areas with mild climates,  allows for longer and more productive factory  campaigns. In southern Idaho, approximately   one-third of the roots are directly processed,   one-third are held in short-term storage, and   one-third are held in long-term storage (greater  than 90 days). Some beets in long-term storage  will be held up to 150 days, leaving roots sus-  ceptible to a number of negative influences.   Extreme temperature fluctuations, excessive   moisture, restricted air flow (snow, soil, weeds,  and rotted roots), microbial development, res-  piration rate, and buildup of impurities can all  negatively impact sucrose recovery. In addition  to disease and water-related problems...

Droplet Kinetic Energy of Moving Spray-Plate Center-Pivot Irrigation Sprinklers
Provedor de dados: 18
Autores: King, B.A.; Bjorneberg, D.L.
The kinetic energy of discrete water drops impacting a bare soil surface generally leads to a drastic reduction in water infiltration rate due to formation of a seal on the soil surface. Under center-pivot sprinkler irrigation, kinetic energy transferred to the soil prior to crop canopy development can have a substantial effect on seasonal runoff and soil erosion, especially when the soil is not protected by crop residue cover.  Droplet kinetic energy of seven commercial off-center action rotating spray-plate sprinklers was characterized over a range of flow rates and pressures. Sprinkler droplet kinetic energy was characterized using two methods; droplet kinetic energy per unit sprinkler discharge and droplet kinetic energy applied per unit water depth...

Autores: Carter, David L.
National concern about nitrate contamination of  groundwater is raisin g many questions about the  use of nitrogen fertilizer to grow high-quality crops.  Some extremists are suggesting that commercial  inorganic nitrogen fertilization should not be permitted.  Such a limitation would seriously reduce crop  productivity and farming profitability. We hope that it does  not occur. However, the farming industry has become  somewhat careless in nitrogen management because  nitrogen fertilizer has been relatively cheap for the past  couple of decades. Commonly, "a little extra nitrogen" has  been applied to assure against a deficiency and less than  maximum yield. in recent years. sugar beet growers have  learned that such a practice can be costly because high...

Nutritional and environmental effects on ammonia emissions from dairy cattle housing: A meta-analysis
Provedor de dados: 18
Autores: Bougouin, Adeline; Leytem, A.B.; Dijkstra, Jan; Dungan, R.S.; Kebreab, Ermias.
Nitrogen (N) excreted in urine by dairy cows can be potentially transformed to ammonia (NH3) and emitted to the atmosphere. Dairy production contributes to NH3 emission, which can create human respiratory problems and odor issues, reduces manure quality, and is an indirect source of nitrous oxide (N2O). The objective of this study was to (i) investigate environmental factors and measurement method that influence NH3 from dairy housing, and (ii) identify key explanatory variables in the prediction of NH3 emissions from dairy barns using a meta-analytical approach. Data from 25 studies were used for the preliminary analysis and data from 10 studies reporting 87 treatment means were used for the meta-analysis. Season, flooring type, manure handling and...

Root rot in sugar beet piles at harvest
Provedor de dados: 18
Autores: Strausbaugh, C.A.
Sugar beet root rots are not only a concern because of reduced yields, but can also be associated with losses in storage.  Our primary sugar beet root rot disease problem in the Amalgamated production area is Rhizoctonia root rot.  However, this rot frequently only penetrates a short distance past the surface of the root before a bacterial complex stops the fungus and continues the rot process.  This rot complex leads to direct yield loss at harvest time along with additional costs in factory processing.  When rotted roots make it into storage piles, they have been shown to compromise surrounding healthy roots.  A recent end-of-harvest storage pile survey of 74 to 76% of the piles at receiving stations in Treasure Valley and Magic Valley has identified...

Drought resistant sugar beets
Provedor de dados: 18
Autores: Tarkalson, D.D.; Eujayl, Imad A.; King, B.A.
Technical Abstract: Increased water demands and drought have resulted in a need to indentify crop hybrids that are drought tolerant, requiring less irrigation to sustain yields. This study was conducted to assess differences in drought tolerance among a group of genetically diverse sugarbeet hybrids. The study was conducted over three consecutive growing seasons (2008-2010) at the USDA Northwest Irrigation and Soils Research Laboratory in Kimberly, ID on a Portneuf silt loam soil (coarse-silty, mixed, superactive, mesic Durinodic Xeric Haplocalcid). Drought tolerance was evaluated by measuring sucrose yield production of six experimental hybrids of KWS SAAT AG and one commercial hybrid (Betaseed Inc.) under six water input treatments. Hybrid drought...

Autores: Leytem, A.B.; Turner, B.L.; Raboy, V.; Peterson, K.L.
Land application of manure can increase P transfer in runoff,  although the risk depends in part on the characteristics of the manure.  We assessed this for calcareous soils using manures from swine (Sus  domesticus) fed one of five barley varieties (Hordeum vulgare L.),  including four low phytate mutants and a normal variety, to produce  manures with a range of total P (6.8-4.9 g P water-soluble P  (4.3-8.0 g P kg-'), total N/P ratios (2.5:1-5.5:1), and total C/P ratios  (31:1-67:1). Two experiments were conducted. First, manures were  incorporated into three soils on a N (150 mg N kg-' soil) or P (27.5 mg  P kg-1 soil) basis three times during a 7-wk incubation. Second, 10  additional soils were incubated for 2 wk following a single P-based  manure...

Contrasting effects of biochar versus manure on soil microbial communities and enzyme activities in an Aridisol
Provedor de dados: 18
Autores: Elzobair, K.A.; Stromberger, M.E.; Ippolito, J.A.; Lentz, R.D.
Biochar has been shown to increase microbial activity, alter microbial community structure, and increase soil fertility in arid and semi-arid soils, but at relatively high rates that may be impractical for large-scale field studies. This contrasts with organic amendments such as manure, which can be abundant and inexpensive if locally available, and thus can be applied to fields at greater rates than biochar. In a field study comparing biochar and manure, a fast pyrolysis hardwood biochar (10 tons per acre), dairy manure (19 tons per acre), a combination of biochar and manure at the aforementioned rates, or no amendment (control) was applied to an Aridisol (n=3) in fall 2008. Plots were annually cropped to corn.  Surface soils (0-12 inches) were sampled...

Beet curly top resistance in USDA-ARS plant introduction lines, 2014.
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Panella, Leonard W.
Curly top caused by Beet curly top virus (BCTV) is a widespread disease problem vectored by the beet leafhopper in semiarid sugar beet production areas. Host resistance is the primary defense against this problem, but resistance in commercial cultivars is only low to intermediate. In order to identify novel sources of curly top resistance, twenty-four plant introduction (PI) lines were screened in a disease nursery in 2014. The lines were arranged in a randomized complete block design with three replications.  A curly top epiphytotic was created by releasing approximately 6 viruliferous beet leafhoppers per plant at the four- to six-leaf growth stage on 23 Jun. Foliar symptoms were evaluated on 16 Jul using a scale of 0-9 (0 = healthy and 9 = dead) in a...

Autores: Dungan, R.S.; Bjorneberg, D.L.; Leytem, A.B.
In this study we conducted simulated spray irrigation events of dairy wastewater to assess the impact of pressure and sprinkler type upon post-sprinkler culturable microorganism concentrations.  Dairy wastewater was sampled before and after it was pumped through sprinklers typically used on center pivot irrigation systems.  Three different sprinklers types were used at three different operating pressures to give a range of water drop sizes.  The microorganisms quantified in this study were total coliforms, Escherichia coli, Clostridium perfringens, heterotrophic bacteria, and coliphage.  In most cases the pre- and post-sprinkler concentrations were determined to be statistically similar, suggesting that culturable viability was not affected when wastewater...

Stabilization of extracellular enzymes may maintain enzymatic activity for ecosystem services such as carbon sequestration, nutrient cycling, and bioremediation, while protecting enzymes from proteolysis and denaturation. A laboratory incubation study was conducted to determine whether a fast pyrolysis biochar (CQuest) derived from oak and hickory hardwood would stabilize extracellular enzymes in soil and prohibit the loss of potential enzyme activity following a denaturing stress, in this case microwaving. Soil was incubated in the presence of biochar (0, 1, 2, 5, or 10% by weight) for 36 days and subsequently exposed to microwave energies of 0, 400, 800, 1600, or 3200 Joules per gram of soil.

Effect of timing of a deficit-irrigation allocation on corn evapotranspiration, yield, water use efficiency and dry mass
Provedor de dados: 18
Autores: Payero, J.O.; Tarkalson, D.D.; Irmak, S.; Davison, D.; Petersen, J.L.
Water regulations have decreased irrigation water supplies in Nebraska and some other areas of the USA  Great Plains. When available water is not enough to meet crop water requirements during the entire  growing cycle, it becomes critical to know the proper irrigation timing that would maximize yields and  profits. This study evaluated the effect of timing of a deficit-irrigation allocation (150 mm) on crop  evapotranspiration (ETc), yield, water use efficiency (WUE = yield/ETc), irrigation water use efficiency  (IWUE = yield/irrigation), and dry mass (DM) of corn (Zea mays L.) irrigated with subsurface drip  irrigation in the semiarid climate of North Platte, NE.

Immunodetection of Two Curtoviruses Infecting Sugar Beet
Provedor de dados: 18
Autores: Durrin, J.S.; Nikolaeva, O.V.; Strausbaugh, C.A.; Karasev, A.V.
Beet leafhopper-transmitted curly top virus is a serious problem in many different crops in the semiarid western U.S., including sugar beet, tomatoes and beans. Curly top is caused by a genetically diverse complex of phloem-limited curtoviruses. Due to the phloem restriction of curtoviruses and the lack of a convenient laboratory host-vector system for curly top virus propagation and purification, no commercial immunodetection tests are available for curtoviruses. Routine diagnostics for curly top relies either on visual symptoms or PCR tests. Lack of an ELISA test system is one of the factors hampering development and screening of the curly top resistant germplasm in, for instance, sugar beet and bean breeding programs. To fill in this gap, we developed...

Soil quality indices are often management driven and attempt to describe key relationships between above- and below-ground parameters.  In terrestrial systems, indices that were initially developed and modified for agroecosystems have been applied to non-agricultural systems in increasing number. We developed a soil quality index in arid and semi-arid ecosystems of the Western US impacted by different types of geologic mineralization using the relationship between vegetation community parameters and soil abiotic and biotic properties. We analyzed these relations in soils associated with three different mineralization types: podiform chromite, Copper/Molybdenum porphyry, and acid-sulfate gold vein systems at four different sites in California and Nevada....

The Rhizoctonia-bacterial root rot complex in sugarbeet caused by Rhizoctonia solani and Leuconostoc mesenteroides can cause significant yield losses.  To investigate the impact of different tillage systems on this complex, field studies were conducted from 2009 to 2011.  Split blocks with conventional and strip tillage as main plot treatments were arranged in a randomized complete block design with four replications.  Within main plots, there were seven treatments (non-inoculated check and six R. solani AG-2-2 IIIB strains).  Regardless of tillage, the roots responded in a similar manner for fungal rot (conventional 8% versus strip 7%), bacterial rot (26% versus 34%), total rot (33% versus 41%), neighboring roots infected (1.7 roots versus 1.5 roots),...

The effects of biochar application to calcareous soils are not well documented. In a laboratory incubation study, a hardwood-based, fast pyrolysis biochar was applied (0, 1, 2, and 10% by weight) to a calcareous soil. Changes in soil chemistry, water content, microbial respiration, and microbial community structure were monitored over a 12-month period. Increasing biochar application rate increased the water holding capacity of the soil-biochar blend, a trait that could be beneficial under water limited situations. Biochar application also caused an increase in plant-available iron and manganese, soil carbon content, soil respiration rates, bacterial populations, and a decrease in soil nitrate-nitrogen concentration. Biochar rates of 2 and 10% altered the...

Autores: Strausbaugh, C.A.; Neher, Oliver T.; Rearick, E.; Eujayl, Imad A.
Root rots in sugar beet storage can lead to million dollar losses because of reduced sucrose recovery.  Thus, studies were conducted to establish better chemical control options and a better understanding of the fungi involved in the rot complex.  A water check and three fungicides (Mertect, Propulse, and Stadium) were investigated for their ability to control fungal rot on sugar beet roots held in long term storage during both the 2012 and 2013 storage seasons.  At the end of September into October, roots were collected on five subsequent weeks, treated, and placed on top of a commercial indoor storage pile until early February.  Both Propulse and Stadium performed well, by reducing fungal growth and rot on roots versus the check by an average of 84 to...

Dryland agroecosystems are generally ideal environments for recycling biosolids.  However, what is the efficacy of biosolids addition to a no-till dryland management agroecosystem?  From 2000 to 2010, we studied application of biosolids from the Littleton/Englewood, CO Wastewater Treatment Plant versus commercial nitrogen fertilizer in dryland no-till wheat (Triticum aestivum, L.)-fallow (WF) and wheat-corn (Zea mays, L.)-fallow (WCF) rotations at a site approximately 50 miles east of Denver, CO.  We tested if biosolids would produce the same yields and grain phosphorus, zinc, and barium concentrations as an equivalent rate of nitrogen fertilizer, that biosolids-borne phosphorus, zinc, and barium would not migrate below the 4 inch soil depth, and that...

Evaluation of fungicide and biological treatments for control of fungal storage rots in sugar beet, 2014
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Olsen L, Nora; Frazier J, Mary; Wambolt, C.
Preventing sucrose losses in storage is important to the economic viability of the sugar beet industry.  In an effort to establish additional measures for reducing sucrose losses in storage, ten fungicide and/or biological treatments were evaluated on sugar beet roots in a commercial sugar beet storage building for their ability to limit fungal growth on roots harvested 2 Oct.  Six of the treatments were applied as a direct spray to roots, but two treatments were applied as a cold fog and two others were applied as a thermal fog.  The treated eight-beet root samples were arranged in a randomized complete block design with 6 replications on top of the commercial sugar beet pile inside a storage building.  Roots were evaluated for fungal growth, root rot,...

Net Nitrogen Mineralization from Past Years' Manure and Fertilizer Applications.
Provedor de dados: 18
Autores: Lentz, R.D.; Lehrsch, G.A.
Manure from the semiarid West’s dairy industries is a rich nutrient source, but its use for crops can be problematic because soil N availability from manure may vary substantially depending on the year of application.  Experimental plots established in Idaho on a Portneuf silt loam (coarse silty, mixed, superactive, mesic Durinodic Xeric Haplocalcid) included six manure treatments and two non-manure treatments with four replicates.  The six manure treatments included combinations of two manure rates, Man-1x (0.31 Mg total N/ha) and Man-3x (0.97 Mg total N/ha) applied in the fall either 1, 2, or 3 years previously.  The two non-manure treatments were urea fertilizer applied per soil test (Fert) and a control with no amendment. We measured net N...

Provedor de dados: 18
Autores: King, B.A.; Winward, T.W.; Bjorneberg, D.L.
Kinetic energy of water droplets has a substantial effect on development of a soil surface seal and infiltration rate of bare soil. Methods for measuring sprinkler droplet size and velocity needed to calculate droplet kinetic energy have been developed and tested over the past 50 years, each with advantages, disadvantages, and limitations. Drop size and velocity of an impact sprinkler at three operating pressures and one nozzle size were measured using a laser precipitation meter and compared with published values obtained using a photographic method. Significant differences in cumulative volume drop size distributions derived from the two measurement methods were found, especially at the highest operating pressure. Significant differences in droplet...

Autores: Niu, M; Appuhamy, J.A.D.R.N; Leytem, A.B.; Dungan, R.S.; Kebreab, Ermias.
The study aimed to examine, simultaneously, the effects of changing dietary forage and crude protein (CP) contents on methane (CH4) emissions and nitrogen (N) excretion from lactating dairy cows. Twelve post-peak lactating Holstein cows were randomly assigned to 4 treatments from a 2×2 factorial arrangement of two dietary forage levels [37.4% (LF) vs. 53.3% (HF) of DM] and two dietary CP levels [15.2% (LP) vs. 18.5% (HP) of DM] in a 4×4 Latin square design with four 18 d periods. Alfalfa hay was the sole source of dietary forage. Cows were fed and milked twice daily. During the first 14 d, cows were housed in a free-stall barn, where enteric CH4 emissions were measured using the GreenFeed system from d 8 to 14 in each period. Cows were then moved to...

Provedor de dados: 18
Autores: Dungan, R.S.; Leytem, A.B.
Collection fluids used in liquid-based bioaerosol samplers can influence the viability of microorganisms. In this study we determined the recovery efficiency of vegetative E. coli O157:H7 cells that were spiked into low viscosity evaporating collection fluids during operation of a BioSampler™ for up to 90 min at room temperature. The collection fluids tested were distilled (DI) water, phosphate-buffered saline (PBS) and osmoprotectants consisting of peptone and/or antifoam or betaine at 0.1% (w/w) in DI water. Using DI water, there was a rapid decline in the recovery of culturable E. coli, with only 11, 3, and 0% being recovered after 30, 60, and 90 min, respectively. Recoveries were substantially greater with use of PBS (53, 25, and 16%, respectively) but...

Influence of Rhizoctonia-bacterial Root Rot Complex on Storability of Sugarbeet
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Rearick, E.; Eujayl, Imad A.; Foote, P.
The Rhizoctonia-bacterial root rot complex can lead to yield loss in the field but may also lead to problems with sucrose loss in storage.  Thus, studies were conducted to investigate if placing sugarbeet roots suffering from root rot together with healthy roots could compromise the ability of the healthy roots to retain sucrose.  Over a three year period, root samples from three commercial cultivars were compared in storage as a healthy (eight healthy roots) or rotted (eight healthy roots + one rotted root) treatment inside an outdoor storage pile.  The experiment was arranged as a split block (healthy in one half of block and rotted in the other) with the whole blocks arranged in a randomized complete block design with four replications.  Samples were...

Biochars impact on soil moisture storage in an Ultisol and two Aridisols

Droughts associated with low or erratic rainfall distribution can cause detrimental crop moisture stress. This problem is exacerbated in the USA’s arid western and southeastern Coastal Plain due to poor rainfall distribution, poor soil water storage, or poorly-aggregated, subsurface hard layers that limit root penetration. We hypothesized that soil physical deficiencies may be improved by biochar applications. Research indicates a single biochar will not serve as a universal supplement to all soils; consequently, biochars may need to be designed with physico-chemical properties that can ameliorate specific soil physical deficiencies. We conducted a laboratory study that examined the effect of biochar on soil moisture retention and aggregate formation....

Late-afternoon-cut hay makes more milk
Provedor de dados: 18
Autores: Mayland, Hank; Shewmaker, Glenn.
Pouring a glass of milk is only a few steps  away from pouring a glass of sunshine. Solar  energy drives photosynthesis in green plants  to produce simple sugars. When these plants are  eaten by the cow, those sugars provide energy to  rumen microorganisms which, in turn, provide  energy to the cow for milk production.  On warm sunshiny days, soluble sugars accumulate  in plants faster than the plants can use  them. At night, photosynthesis does not operate,  and there is a loss of soluble sugars. This whole  process results in a daily cycling of soluble sugars  in the forage. Figure 1 clearly shows the gradual  accumulation of plant sugar which builds as  the day progresses. The drop in plant sugars occurs  sometime after sunset.

Transport and Fate of MethyI Iodide and Its Pest Control in Soils
Provedor de dados: 18
Autores: Lou, Lifang; Ashworth, Daniel; Dungan, R.S.; Xuan, Richeng; Yates, S.R.
For fumigants, information on transport and fate, as well as pest control, is needed to develop management practices with the fewest human and environmental health risks while offering sufficient pest control efficacy. For this purpose, a 2-D soil chamber (60 cm wide, 60 cm long, and 6 cm thick) with a surface-mounted flux chamber was designed to determine volatilization, spatial and temporal distribution of soil gas-phase concentration, degradation and organism survivability after methyl iodide (MeI) fumigation. Three types of pests (barnyardgrass seed [Echinochloa crus-galli], citrus nematode [Tylenchulus semipenetrans], and fungi [Fusarium oxysporum]) were used to give a broad spectrum of pest control information. After MeI fumigation at a rate of 56.43...

Autores: King, B.A.; Bjorneberg, D.L.; Trout, T.J.; Mateos, L; Araujo, D. F.; Costa, R. N.
The area irrigated by furrow irrigation in the U.S. has been steadily decreasing but still represents about 20% of the total irrigated area in the U.S. Furrow irrigation sediment loss is a major water quality issue and a method for estimating sediment loss is needed to quantify the environmental impacts and estimate effectiveness and economic value of conservation practices. Artificial neural network (NN) modeling was applied to furrow irrigation to predict sediment loss as a function of hydraulic and soil conditions.  A data set consisting of 1926 furrow evaluations spanning three continents and a wide range of hydraulic and soil conditions was used to train and test a multilayer perceptron feed forward NN model. The final NN model consisted of 16 inputs,...

Conversion of potato ridged-row planting systems to wide bed planting systems may increase water and nitrogen use efficiency in commercial irrigated potato production systems by reducing the amount of irrigation water and water applied nitrogen fertilizer bypassing the potato root zone. Wide bed planting systems consist of planting multiple rows on a wide bed with 20 to 35% higher plant population than found in conventional ridgedrow planting systems. The objective of this study was to evaluate the effect planting system has on yield response of ‘Russet Norkotah’ potato to irrigation and nitrogen.

EVALUATION OF BRAVO FOR DISEASE CONTROL IN ALFALFA CULTIVARS GROWN FOR HAY, 1983: The alfalfa cultivars, having Turkish  and/or Flemish parentage and which were adapted to the northern and central U.S., were established under irrigated culture in late spring, 1981, on a  productive Portneuf silt loam. Plots were randomized block with 4 replications, each split for Bravo, and were 5 x 25 ft. Following the establishment  year, Bravo was applied to the stubble prior to regrowth in an attempt to control inoculum. The tractor-mounted spray rig, which had a 25-ft boom (T-jet  6503 nozzles, 40 psi, 35 gpm) was driven across only the Bravo-treated plots in 1982, but across all plots in 1983 to eliminate the wheel compaction  variable.

Ft. Collins sugar beet germplasm evaluated for rhizomania and storage rot resistance in Idaho, 2013
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Panella, Leonard W.
Rhizomania caused by the Beet necrotic yellow vein virus (BNYVV) is a worldwide problem that can lead to loss of tonnage and lower percent sucrose in the field.  BNYVV can also reduce the storability of roots.  To identify germplasm with resistance to these problems, 50 sugar beet germplasm lines developed by the USDA-ARS Ft. Collins sugar beet program and four check cultivars were screened in a field experiment arranged in a randomized complete block design with six replications.  During the growing season, plants were evaluated for foliar rhizomania symptoms.  At harvest on 7 October 2013, roots were evaluated for rhizomania symptoms and then placed into an indoor commercial sugar beet storage building in Paul, ID.  Foliar symptoms ranged from 0% for...

Sugar beet germplasm evaluated for rhizomania and storage rot resistance in Idaho, 2011.
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Panella, Leonard W.
Rhizomania caused by the Beet necrotic yellow vein virus (BNYVV) is a worldwide problem that can lead to loss of tonnage and lower percent sucrose in the field.  BNYVV can also reduce the storability of roots.  To identify germplasm with resistance to these problems, 14 sugarbeet germplasm lines developed by the USDA-ARS Ft. Collins sugarbeet program were screened in a field experiment arranged in a randomized complete block design with 5 replications.  During the growing season plants were evaluated for foliar rhizomania symptoms.  At harvest on 29 September, roots were evaluated for rhizomania symptoms and then placed into an indoor commercial sugarbeet storage building in Paul, ID.  Foliar symptoms ranged from 0% for one of the resistant checks to 99%...

Determing Higher Fatty Acid Levels in Plant Materials
Provedor de dados: 18
Autores: Mayland, H.F.
The higher fatty acids (HFA) are important plant constituents that are implicated in the grass tetany hazard in livestock.  A method is given whereby a technician can analyze 12 forage samples daily for HFA content.    The method consists of saponifying the plant material in ethanol and KOH and extracting the subsequently acidified HFA with petroleum ether.  The petroleum ether phase is evaporated and the HFA residue is dissolved in ethanol and then titrated with standardized isobutanolic KOH in the absence of Oxygen by using an Nitrogen atmosphere.  A standard plant sample, analyzed over a 37-day period, had a mean of 136 mmol H+kg ± 4.5, where 0.1 mmol H+ℓ palmitic standard  was determined with an accuracy of 99 ± 1.9%.

Collector design for measuring high intensity time variant sprinkler application rates
Provedor de dados: 18
Autores: King, B.A.; Winward, T.W.; Bjorneberg, D.L.; Wall, R.W.
Peak water application rate in relation to soil water infiltration rate and soil surface storage capacity is important in the design of center pivot sprinkler irrigation systems for efficient irrigation and soil erosion control.  Measurement of application rates of center pivot irrigation systems has traditionally used tipping bucket rain gauges.  Calculation of application rate from tipping bucket rain gauge measurements restricts computed application rate to a discrete multiple of the rain gauge resolution and time interval.  This limits the resolution of application rate measurement, especially for time intervals less than 15 minutes.  A collector was designed to measure time variant high intensity sprinkler application rates under field conditions with...

Delinearing site-specific management zones for pH-induced iron chlorosis

Autores: Kyaw, T.; Ferguson, R.B.; Adamchuk, V.I.; Marx, D.B.; Tarkalson, D.D.; McCallister, D.L.
Iron chlorosis can limit crop yield, especially on calcareous soil. Typical management for iron chlorosis includes the use of iron fertilizers or chlorosis tolerant cultivars. Calcareous and non-calcareous soil can be interspersed within fields. If chlorosis-prone areas within fields can be predicted accurately, site-specific use of iron fertilizers and chlorosis-tolerant cultivars might be more profitable than uniform management. In this study, the use of vegetation indices (VI) derived from aerial imagery, on-the-go measurement of soil pH and apparent soil electrical conductivity (ECa) were evaluated for their potential to delineate chlorosis management zones. The study was conducted at six sites in 2004 and 2005. There was a significant statistical...

The nature of phosphorus in calcareous soils
Provedor de dados: 18
Autores: Leytem, A.B.; Mikkelsen, R.L.
Calcareous soils (containing free lime) are common in many arid and semi-arid regions  of North America and occur as inclusions in more humid regions. Phosphorus  (P) is very reactive with lime. Following fertilizer application, P undergoes a series of  reactions that gradually reduce its solubility. In most calcareous soils, there does  not appear to be a strong agronomic advantage of any particular P source when  managed properly. Organic matter can inhibit P fixation reactions to some extent.  Some fertilizer recommendations call for additional P to be added when the soil  contains high amounts of free lime.

Purple sulfur bacteria (PSB) in livestock wastewaters use reduced sulfur compounds and simple volatile organics as growth factors. As a result, the presence of PSB in manure storage ponds or lagoons is often associated with reduced odors. In this study, our objectives were to use molecular- and culture-based techniques to evaluate the occurrence of PSB in eight dairy wastewater ponds and identify physiochemical properties that might cause blooms to occur. Community DNA was extracted from composited wastewater samples, then the PufM gene and a conservative sequence for Chromatiaceae were amplified.

Polyacrylamide treatments for reducing seepage in soil-lined reservoirs: A field evaluation
Provedor de dados: 18
Autores: Lentz, R.D.; Kincaid, D.C.
Irrigation water supplies are becoming limited, and there is a need to extend the usefulness of current water resources. Previous laboratory studies demonstrated that certain water-soluble polyacrylamide solution (WSPAM) and cross-linked PAM granule (XPAM) treatments effectively reduced infiltration into soils. We evaluated the efficacy of these treatments for reducing water seepage losses in an unlined irrigation reservoir. Five treatments were applied to plots on the lower side slopes of a reservoir basin before it was filled in April 2001: controls; 0.016 kg m -2 WSPAM (1000 mg L -1 solution); 0.2 kg m -2 XPAM + 0.13 kg m -2 NaCl; 0.4 kg m -2 XPAM + 0.13 kg m -2 NaCl; and 0.8 kg m -2 XPAM only. Ring-cylinder seepage meters installed in each experimental...

Resistance to curly top of sugar beet in germplasm developed at USDA-ARS Ft. Collins, 2013
Provedor de dados: 18
Autores: Panella, Leonard W.; Strausbaugh, C.A.
Seventy-one sugar beet (Beta vulgaris L.) lines from the USDA-ARS Ft. Collins sugar beet program and three control lines were screened for resistance to Beet curly top virus (BCTV) in 2013.  Commercial cultivars ‘Monohikari’ (susceptible), ‘HM PM90’ (resistant) and Betaseed line Beta G6040 (resistant) were included as controls.  The curly top evaluation was conducted at the USDA-ARS North Farm in Kimberly, ID, and was grown using typical agronomic practices. The plots were two rows 10 ft long with 22-in row spacing and arranged in a randomized complete block design with four replications. Plants were inoculated at the four- to six-leaf growth stage on June 27 with approximately six viruliferous beet leafhoppers per plant. The beet leafhoppers were...

Copper and zinc speciation in a biosolids-amended semiarid grassland soil
Provedor de dados: 18
Autores: Ippolito, J.A.; Barbarick, K.A.; Brobst, R.B.
Predicting trace metal solid phase speciation changes associated with long-term biosolids land application is important for understanding and improving environmental quality.  Biosolids were surface-applied (no incorporation; 0, 1, 2, 5, 10, and 15 tons per acre) to a semi-arid grassland in 1991 (single) or again in 2002 (repeated).  In July 2003, soils were obtained from the 0-3, 3-6, and 6-12-inch depths in all plots.  Using soil pH, soluble anion and cation concentrations from 0.01 moles per liter calcium chloride extractions, and dissolved organic carbon content, copper and zinc associated with minerals, hydrous ferric oxide, or dissolved organic phases was modeled using Visual Minteq.

Relationship Between Tissue Zinc Levels and Maturity Period of Field Beans
Provedor de dados: 18
Autores: Boawn, L.C.; Rasmussen, P.E.; Brown, J.W.
Most bean varieties (Phaseolus vulgaris) are susceptible  to zinc deficiency and, if grown where  zinc deficiency occurs, are invariably listed among  those crops with the greatest need for zinc fertilization  (1, 2, 3, 4). Bean plants with mild to moderate zinc deficiency  symptoms early in the growing season may  recover and produce essentially a normal yield. However,  as several individuals have observed (1, 2, 3)  this early-season zinc deficiency invariably results in  delayed maturity. This is a critical factor in geographical  areas where beans may be damaged by fall  rains or early frost.  The research reported here establishes quantitative  relationships between the zinc level in bean tissues  and the number of days required for maturation. The...

Nitrogen Availability From Manure in Years Following a One-Time Application
Provedor de dados: 18
Autores: Lentz, R.D.; Lehrsch, G.A.
Manure from the semiarid West’s dairy industries is a rich nutrient source, but its use for crops can be problematic because soil N availability from manure may vary substantially depending on the year of application.  Experimental plots established in Idaho on a Portneuf silt loam (coarse silty, mixed, superactive, mesic Durinodic Xeric Haplocalcid) included six manure treatments and two non-manure treatments with four replicates.  The six manure treatments included combinations of two manure rates, Man-1x (277 lbs total N/ac) and Man-3x (866 lbs total N/ac) applied in the fall either 1, 2, or 3 years previously.  The two non-manure treatments were urea fertilizer applied per soil test (Fert) and a control with no amendment. We measured net N...

Nonstructural carbohydrate and digestibility patterns in orchardgrass swards during daily defoliation sequences initiated in evening and morning
Provedor de dados: 18
Autores: Griggs, T.C.; McAdam, J.W.; Mayland, H.F.; Burns, J.C.
Herbage soluble carbohydrate (SC) levels vary diurnally and livestock  intake can be higher for herbage harvested or allocated to  animals in the evening than in the morning. Few assessments of SC  and digestibility patterns have been made during sward depletion in  rotationally stocked orchardgrass (Dactylis glomerata L.). We tested  the hypothesis that simulated evening daily pasture allocation increases  24-h mean herbage SC and digestibility levels relative to morning  allocation. Total nonstructural carbohydrate (TNC) and in vitro  true dry matter digestibility (IVTDMD) levels were compared during  24-h clipping sequences initiated at 1900 h (PM) and 0700 h (AM).  Sward height was progressively reduced from 40 to 8 cm at 6-h intervals  in October,...

Autores: Strausbaugh, C.A.; Eujayl, Imad A.; Foote, P.
Insect feeding and vectoring of viruses cause serious problems in sugarbeet production worldwide.  In order to ameliorate insect and disease problems on sugarbeet, two seed treatments, Poncho Beta (60 g a.i. clothianidin + 8 g a.i. beta-cyfluthrin/100,000 seed) and Cruiser Tef (60 g a.i. thiamethoxam + 8 g a.i. tefluthrin/100,000 seed) were investigated (the neonicotinoid was tested alone in some trials).  The two seed treatments and an untreated check were tested in a series of seven field trials from 2006 to 2008 along with various commercial sugarbeet cultivars in a randomized complete block design with eight replications per trial.  Natural insect incidence and curly top symptoms were evaluated.  Both Poncho and Cruiser provided significant reduction...

Greenhouse gas and ammonia emissions from an open-freestall dairy in Southern Idaho
Provedor de dados: 18
Autores: Leytem, A.B.; Dungan, R.S.; Bjorneberg, D.L.; Koehn, A.C.
Concentrated dairy operations emit trace gases such as ammonia (NH3), methane (CH4), and nitrous oxide (N2O) to the atmosphere. The implementation of air quality regulations in livestock-producing states increases the need for accurate on-farm determination of emission rates. The objective of this study was to determine the emission rates of NH3, CH4, and N2O from the open-freestall and wastewater pond source areas on a commercial dairy located in southern Idaho. Gas concentrations and wind statistics were measured each month and used with an inverse dispersion model to calculate emission rates. Average emissions per cow per day from the open-freestall source area were 0.10 kg NH3 and 0.47 kg CH4. Average emissions from the wastewater ponds (g m-2 d-1)...

Rhizoctonia root rot resistance in commercial sugar beet cultivars in Twin Falls County, ID, 2012
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Eujayl, Imad A.
Rhizoctonia root rot continues to be a concerning problem in sugar beet production areas.  To investigate resistance to this disease in 26 commercial sugar beet cultivars, field studies were conducted with three Rhizoctonia solani AG-2-2 IIIB strains.  Based on means for the 26 cultivars, surface rot ranged from 0 to 96% depending on the strain-cultivar combination.  Both the number of dead plants and root surface area rotted resulted in significant (P &lt; 0.0002) cultivar differences.  Based on Spearman’s rank correlation coefficient, there was always a significant relationship (P &lt; 0.0390) when comparing cultivar performance across all three strains regardless of disease variable.  The three most resistant cultivars performed well against all strains...

Aluminum-based water treatment residuals (Al-WTR) have a strong affinity to sorb phosphorus.  In a proof-of-concept greenhouse column study, Al-WTR was surface-applied at 0, 62, 124, and 248 Mg/ha to 15 cm of soil on top of 46 cm of sand; Al-WTR rates were estimated to capture 0, 10, 20, and 40 years of phosphorus from an urban watershed entering an engineered wetland in Boise, Idaho, USA.  Creeping red fescue (Festuca rubra) was established in all columns; one set of columns received no Al-WTR or plants.  After plant establishment, once per week over a 12-week period, ~1.0 pore volumes of ~0.20 mg phosphorus/L was added to each column.  Infiltration rates were measured, leachate was collected and analyzed for soluble phosphorus, and fescue yield,...

Characterizing droplet kinetic energy applied by moving spray-plate center pivot irrigation sprinklers
Provedor de dados: 18
Autores: King, B.A.; Bjorneberg, D.L.
The kinetic energy of discrete drops impacting a bare soil surface is generally observed to lead to a drastic reduction in water infiltration rate due to soil surface seal formation.  Under center pivot sprinkler irrigation, kinetic energy transferred to the soil prior to crop canopy development can have a substantial effect on seasonal runoff and soil erosion.  In the design of center pivot irrigation systems, selection of sprinklers with minimum applied kinetic energy could potentially minimize seasonal runoff and erosion hazard.  Size and velocity of drops from five common center pivot sprinklers with flow rates of approximately 43 L/min were measured using a laser in the laboratory. The data were used to evaluate various approaches to characterize...

Autores: Payero, J.O.; Tarkalson, D.D.; Irmak, S.; Davison, D.; Petersen, J.L.
Quantifying the local crop response to irrigation is important for establishing adequate irrigation management strategies. This study evaluated the effect of irrigation applied with subsurface drip irrigation on field corn (Zea mays L.) evapotranspiration (ETc), yield, water use efficiencies (WUE = yield/ETc, and IWUE = yield/irrigation), and dry matter production in the semiarid climate of west central Nebraska. Eight treatments were imposed with irrigation amounts ranging from 53 to 356 mm in 2005 and from 22 to 226 mm in 2006. A soil water balance approach (based on FAO-56) was used to estimate daily soil water and ETc. Treatments resulted in seasonal ETc of 580–663 mm and 466–656 mm in 2005 and 2006, respectively. Yields among treatments differed by as...

Provedor de dados: 18
Autores: Tarkalson, D.D.; Payero, J.O.; Ensley, S.M.; Shapiro, C.A.
Nitrate leaching from agricultural soils can increase groundwater nitrate concentrations.  The objectives of the study were to assess the accumulation and movement of nitrate in the  soil profile over a 2-year period under deficit irrigation conditions following a one time  application of N in cattle feedlot manure and commercial fertilizer to corn at rates to achieve  yield goals expected under conditions of full irrigation. Cattle manure and ammonium  nitrate were applied in 2002 at the University of Nebraska recommended rate (1M and 1F ;  respectively) and cattle manure was applied at twice the recommended rate (2M) for N for  the 2002 corn (Zea mays L.) crop. The recommended rate was based on expected yields under  full irrigation. The manure N...

Irrigated silage corn is the main crop used for phosphorus removal; however little is known about the actual amounts of phosphorus removed under southern Idaho growing conditions. The purpose of this study was to survey phosphorus removal by irrigated corn grown for silage in southern Idaho under variable soil test phosphorus concentrations. In this survey whole plant corn tissue phosphorus concentrations ranged from 0.116 to 0.307% total phosphorus and averaged 0.208%, which is lower than Natural Resources Conservation Services estimates used prior to 2007 (0.26% phosphorus) but higher than estimates used since 2007 (0.185%).  The study was used by NRCS to update nutrient management planning software used by planners in Idaho.

Autores: Strausbaugh, C.A.; Eujayl, Imad A.; Rearick, E.; Foote, P.
Thirty-five experimental and four commercial check sugar beet cultivars were evaluated in a commercial sprinklerirrigated  sugar beet field near Jerome, ID where winter wheat was grown in 2007. The field trial relied on natural infection  for rhizomania development. The plots were planted on 22 Apr 08 to a density of 142,560 seeds/A, and thinned to 47,520  plants/A on 30 May. Plots were four rows (22-in. row spacing) and 34.5 ft long. The experimental design was a randomized  complete block design with four replications per cultivar. The crop was managed according to standard cultural practices.  The roots were mechanically topped and the center two rows were collected with a mechanical harvester on 9 Oct. At  harvest the roots were evaluated for...

Livestock GRACEnet: A workgroup dedicated to evaluating and mitigating emissions from livestock production
Provedor de dados: 18
Autores: Leytem, A.B.; Dungan, R.S.
livestock operations can potentially affect air quality at local, regional, and even global scales. These pollutants, many of which are generated through various anthropogenic activities, are being increasingly scrutinized by regulatory authorities. Regulation of emissions from livestock production systems will ultimately increase on farm costs, which will then be passed onto consumers.  Therefore, it is essential that scientifically based emission factors are developed for on-farm emissions of air quality constituents to improve inventories and assign appropriate reduction targets. To generate a larger database of on-farm emissions, the USDA–ARS created the workgroup Livestock GRACEnet (Greenhouse gas Reduction through Agricultural Carbon Enhancement...

DNA Fingerprinting of Sugarbeet Varieties to Track Root Rot. 2010
Provedor de dados: 18
Autores: Eujayl, Imad A.; Strausbaugh, C.A.
The sugar beet industry is continuously undertaking major efforts   to reduce postharvest sucrose losses. In Idaho sugarbeet roots   may be stored indoors or outdoors for up to five months. Sugarbeet variety genetic make-up, pre-harvest field conditions, harvest   practices, and post-harvest storage conditions can affect storability   significantly. Physical root conditions and root health before deliv-  ery to the pile contribute to the magnitude of sucrose losses.          Growers chose different varieties for a certain season and may   plant more than one variety in a field. This practice renders it difficult to collect information on the exact location of varieties in the   field and storage piles. Additionally, it’s a daunting task to physically   tag...

Nitrogen Availability and Uptake by Sugarbeet in Years Following Manure Application
Provedor de dados: 18
Autores: Lentz, R.D.; Lehrsch, G.A.
The use of solid dairy manure for sugarbeet production is problematic because beet yield and quality are sensitive to deficiencies or excesses in soil N, and soil N availability from manure varies substantially depending on the year of application. Experimental treatments included combinations of two manure rates (0.33 and 0.97 Mg total N ha-1) and three application times, and no manure treatments (control and urea fertilizer). We measured soil net N mineralization and biomass, N uptake, and yields for sprinkler-irrigated sugarbeet. On average, the 1-year-old, low-rate manure, and 1- and 2-year-old, high-rate manure treatments produced 1.2-fold greater yields, 1.1-fold greater estimated recoverable sugar, and 1.5-fold greater gross margins than that of...

Provedor de dados: 18
Autores: Thacker, P.A.; Haq, I.; Willing, B.P.; Leytem, A.B.
A total of 240 day-old broiler chicks were used to study the effects of phytase on performance and phosphorus (P)  excretion from birds fed diets containing low phytate barleys formulated without inorganic P. A positive control based on Harrington  barley (HB) was formulated to meet requirements for total P. Three experimental diets, based on either HB (0.39% total P with 0.28%  phytate P) or the low phytate varieties LP 422 (0.36% total P with 0.14% phytate P) and LP 955 (0.40% total P with 0.0 I% phytate P),  were formulated to be below requirements for total P by removing all the inorganic P from the diet. The four diets were fed with and  without 1,000 FTU/kg phytase. Apparent P digestibility was significantly higher (p&lt;0.01) for birds fed the low...

Twenty-five experimental sugarbeet hybrids submitted to the official variety trials were evaluated for resistance to Beet curly top virus (BCTV).  Hybrids were planted in a commercial sprinkler-irrigated sugarbeet field and exposed to a natural epiphytotic of BCTV.  Experimental units were arranged in a randomized complete block design with seven replications.  Plots were evaluated for BCTV based on a Disease Index (DI) scale of 0 to 9 (no symptoms to dead) on Sept 14, 2004 by three raters.  The moderately severe epiphytotic resulted in uniform disease pressure and significant differences between hybrids for DI, root yield, sugar content, and estimated recoverable sugar.  Our disease ratings were positively correlated with (r = 0.632, P &lt; 0.0001)...

Beef feedlot manure distributed to row crop production areas is a potential surface water contaminant source of the steroid hormones commonly used in beef cattle production. This article reports on research conducted at the University of Nebraska Haskell Agricultural Laboratory near Concord, Nebraska, in July 2009. Manure, collected from beef feedlot pens, was stockpiled for ten months prior to application to a row crop field. Previous research identified that the detection frequency of steroid hormones in beef manure varies greatly. Thus, a surrogate (17 alpha-ethynylestradiol, EE2) was applied at a rate of 75 g per ha to ensure detectable concentrations in surface runoff samples. EE2 was applied directly to beef cattle manure and to bare soil. The EE2...

Beet curly top resistance in USDA-ARS Kimberly sugar beet germplasm, 2013
Provedor de dados: 18
Autores: Eujayl, Imad A.; Strausbaugh, C.A.
Curly top caused by Beet curly top virus is a widespread disease problem vectored by the beet leafhopper in semiarid sugar beet production areas.  Host resistance is the primary defense against this problem, but resistance in commercial cultivars is only low to intermediate.  In order to identify novel sources of curly top resistance, 14 sugar beet lines were screened in a disease nursery in 2013.  The lines were arranged in a randomized complete block design with six replications.  A curly top epiphytotic was created by releasing six viruliferous beet leafhoppers per plant at the four- to six-leaf growth stage on 27 Jun.  Foliar symptoms were evaluated on 16 Jul using a scale of 0-9 (0 = healthy and 9 = dead) in a continuous manner.  Curly top symptom...

Impact of removing straw from wheat and barley fields: A literature review

Autores: Tarkalson, D.D.; Brown, B.; Kok, H.; Bjorneberg, D.L.
The sustainability of straw removal from wheat and barley fields from the standpoint of  its effects on soil properties and nutrient cycling is a concern. A recent literature review  reveals that there is no negative effect of small grain straw removal on soil organic carbon  (SOC) content with irrigated conditions. With rainfed conditions, the results could be  more variable and depend on site productivity. Large amounts of nutrients are removed  when straw is removed, accelerating the rate of nutrient depletion and cost of replacing  these nutrients.

Case Study: On-Farm Evaluation of Liquid Dairy Manure Application Methods to Reduce Ammonia Losses
Provedor de dados: 18
Autores: Leytem, A.B.; Bjorneberg, D.L.; Sheffield, R.E.; de Haro Marti, M.E.
The volatilization of NH3 from landapplied manure is not only a loss of valuable N, but also an air quality concern because NH3 plays a role in the formation of airborne particulate matter, which can be a health hazard. The relative differences in potential NH3 losses from land application of liquid dairy manure were determined via 3 methods: surface application, Aerway incorporation (shallow incorporation with a rolling tine aerator), and subsurface injection. Liquid manure was applied at a rate of 190 m3/ha on 4 farms with average N and P application rates ranging from 28 to 130 kg N/ha and 6 to 36 kg P/ha, respectively. Average NH3 concentrations were measured with passive samplers for 3 d after manure application and ranged from 0.03 to 0.21 mg...

Provedor de dados: 18
Autores: Gillen, A.M.; Bliss, F.A.
An F2 population from a single F1 plant from the cross of peach [Prunuspersica (L.) Batsch] rootstock cultivars  Harrow Blood (HB) x Okinawa (Oki) was used to locate the Mi locus, which conditions resistance to Meloidogyne incognita (race 1) (Kofoid and White) Chitwood. These data and comparison of common markers among published genetic  linkage maps placed the Mi locus on Prunus L. linkage group 2. Two restriction fragment length polymorphisms (RFLPs)  [linked at 4.8 and 6.8 centimorgan (cM), repulsion phase] and one random ampli?ed polymorphic DNA (RAPD) marker  (linked at 9.5 cM, coupling phase) were linked to Mi. The RAPD marker was cloned, sequenced, and converted to a  polymerase chain reaction (PCR)-based cleaved ampli?ed polymorphic sequence (CAPS)...

Nutrient losses from manure and fertilizer applications as impacted by time to first runoff event
Provedor de dados: 18
Autores: Smith, D.R.; Owens, P.R.; Leytem, A.B.; Warnemuende, E.A.
Nutrient losses to surface waters following fertilization contribute to eutrophication. This study was conducted to compare the impacts of  fertilization with inorganic fertilizer, swine (Sus scrofa domesticus) manure or poultry (Gallus domesticus) litter on runoff water quality, and  how the duration between application and the first runoff event affects resulting water quality. Fertilizers were applied at 35 kg P ha-1-, and  the duration between application and the first runoff event varied between 1 and 29 days. Swine manure was the greatest risk to water quality  1 day after fertilization due to elevated phosphorus (8.4 mg P L -1) and ammonium (10.3 mg NH4-N L-1) concentrations; however, this risk  decreased rapidly. Phosphorus concentrations were 2.6...

Biochar and manure effects on net nitrogen mineralization and greenhouse gas emissions from calcareous soil under corn
Provedor de dados: 18
Autores: Lentz, R.D.; Ippolito, J.A.; Spokas, K.A.
Few multiyear field studies have examined the impacts of a one-time biochar application on net N mineralization and greenhouse gas emissions in an irrigated, calcareous soil; yet such applications are hypothesized as a means of sequestering atmospheric CO2 and improving soil quality.  We fall-applied four treatments, stockpiled dairy manure (42 Mg/ha dry wt.); hardwood-derived biochar (22.4 Mg/ha); combined biochar and manure; and no amendments (control).  Nitrogen fertilizer was applied in all plots and years based on treatment’s pre-season soil test N and crop requirements, and accounting for estimated N mineralized from added manure.  From 2009 to 2011 we measured greenhouse gas fluxes using vented chambers, net N mineralization (NNM) using buried bags,...

Autores: Ippolito, J.A.; Blecker, S.W.; Freeman, C.L.; McCulley, R.L.; Blair, J.M.; Kelly, E.F.
Soil P transformations and distribution studies under water limited conditions that characterize many grasslands may provide further insight into the importance of abiotic and biotic P controls within grassdominated ecosystems. We assessed transformations between P pools across four sites spanning the shortgrass steppe, mixed grass prairie, and tallgrass prairie along a 400-mm precipitation gradient across the central Great Plains. Pedon total elemental and constituent mass balance analyses reflected a pattern of increased chemical weathering from the more arid shortgrass steppe to the more mesic tallgrass prairie. Soil surface A horizon P accumulation was likely related to increased biocycling and biological mining. Soluble P, a small fraction of total P...

The use of biochar has received growing attention with regards to improving the physico-chemical properties of highly weathered Ultisols and Oxisols, yet very little research has focused on effects in Aridisols.  The objective of this study was to investigate the effect of either low or high temperature (250 or 500C) pyrolyzed switchgrass biochar on two Aridisols.  In a pot study, biochar was added at 2% w/w to either a Declo loam (Xeric Haplocalcids) or a Warden very fine sandy loam (Xeric Haplocambids) and then incubated at 15% moisture content (by weight) for 127 days; a control (no biochar) was also included.  Soils were leached with 1.2 to 1.3 pore volumes of deionized water on days 34, 62, 92, and 127, and cumulative leachate Ca, K, Mg, Na, P, Cu,...

Nutrient loads and sediment losses in sprinkler irrigation runoff affected by compost and manure
Provedor de dados: 18
Autores: Lehrsch, G.A.; Lentz, R.D.; Westermann, D.T.; Kincaid, D.C.
High water application rates beneath the outer spans of center pivot sprinkler systems can cause runoff, erosion, and nutrient losses, particularly from sloping fields.  This study determined runoff, sediment losses, and loads of nutrients (dissolved organic C, Nitrate-N, ammonium-N, total phosphorus [TP], ferric-oxide strip phosphorus [FeO P], dissolved reactive phosphorus [DRP], K, Ca, Mg, and Na) in sprinkler runoff for two years after a single application of either stockpiled or composted dairy manure.  The two-year field investigation studied five treatments, including a non-amended control, in each of six blocks, with each block situated under a different span of a moving-lateral sprinkler system.  In October 1999, we incorporated 29.1 or 71.7 Mg/ha...

Growth promoting steroids and steroid-like compounds (GPSC) used by the US beef cattle industry are potential contaminants to water resources. Manure generated in concentrated animal feeding operations contains GPSCs that may enter the environment. Several studies have focused on off-site impacts of GPSC in aquatic life and suggest possible adverse impacts such as abnormal blood hormone levels, masculinization of females, feminization of males, altered sex ratios, intersexuality and reduced fertility. Other studies point to potential human health impacts including increased incidence of human cancers, sexual disorders, and decline in male: female ratio in human beings. However, the use of GPSCs in beef production provides benefits to both cattle producers...

Influence of rhizomania on sugarbeet storability
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Eujayl, I.A.
Rhizomania caused by Beet necrotic yellow vein virus (BNYVV) and storage losses are serious sugar beet production problems.  To investigate the influence of BNYVV on storability, six sugar beet cultivars varying for resistance to BNYVV were grown in 2005 and 2006 in southern Idaho fields with and without BNYVV infested soil.  At harvest, samples from each cultivar were placed in an outdoor pile as a randomized complete block design with 4 reps in Twin Falls, ID and were removed on 40-day intervals starting the end of October.  After 144 and 142 days in storage, sugar reduction across cultivars averaged 20 and 13% without and 68 and 21% with BNYVV for the 2005 and 2006 roots, respectively.  In the December samplings, frozen root area was 1 and 2% without...

Interaction of sugar beet host resistance and rhizoctonia solani AG-2-2 IIIB strains
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Eujayl, Imad A.; Panella, Leonard W.
Rhizoctonia root rot caused by Rhizoctonia solani can cause serious economic losses in sugar beet fields.  Preliminary evidence suggests there could be interactions between different strains and resistance sources.  Thus, field studies were conducted to determine if nine R. solani AG-2-2 IIIB strains varied for virulence when compared with a non-inoculated check and interacted with five sugar beet lines (four resistant lines and a susceptible check).  The studies were arranged in a randomized complete block design with six replications.  Roots were evaluated for surface rot and internal fungal and bacterial rot in September.  All strains were virulent on the susceptible check, FC901/C817, and had the same ranking (r = 1.0) regardless of disease variable....

Evaluation of center pivot sprinkler wind drift and evaporation measurement technique
Provedor de dados: 18
Autores: King, B.A.; Dungan, R.S.; Bjorneberg, D.L.
Wind drift and evaporation losses (WDELs) are an often discussed topic in regards to center pivot sprinkler irrigation efficiency.  Opinions on the magnitude of WDELs vary widely, in part due to the wide variation in WDEL values published in the literature.  The magnitude of WDELs reported in the literature range from 2 to 45%.  The common technique employed to measure WDEL is to use catch cans and compare the measured volume of catch with the volume of water applied based on sprinkler nozzle size, operating pressure and spacing with the difference being WDEL.  The inaccuracies of catch cans resulting from wind effects on catch efficiency and evaporation of water from the catch can prior to measurement have led to the wide range in WDEL reported in the...

The presence of antibiotic drug residues, antibiotic resistant bacteria, and antibiotic resistance genes in agroecosystems has become a significant area of research in recent years, and is a growing public health concern. While antibiotics are utilized for human medicine and agricultural practices, the majority of antibiotic use occurs in food animals where these drugs have historically been used for growth promotion, in addition to prevention and treatment of disease. The widespread use of antibiotics combined with the application of human and animal wastes to agricultural fields introduces antibiotic-related contamination into the environment. While overt toxicity in organisms directly exposed to antibiotic in agroecosystems is generally not an issue due...

Ethanol production from the steam-exploded mixture of 75% cotton gin waste and 25% recycled paper sludge in various conditions was investigated by semisimultaneous saccharification and fermentation (SSSF) consisting of a pre-hydrolysis and a simultaneous saccharification and fermentation (SSF). Four cases were studied: 24-h pre-hydrolysis + 48-h SSF (SSSF 24), 12-h pre-hydrolysis + 60-h SSF (SSSF 12), 72-h SSF, and 48-h   hydrolysis + 24-h fermentation (SHF). The ethanol concentration, yield, and productivity of SSSF 24 were higher than those of the other operations. A model of SSF was used to simulate the data for four components in SSF.

Sugar beet germplasm and commercial check cultivars were evaluated in a commercial sprinkler-irrigated sugar beet  field near Rupert, ID where winter wheat was grown in 2006. The field trial relied on natural inoculum for rhizomania  development. The seed was treated with clothianidin (2.1 oz a.i. per 100,000 seed) to limit the influence of pests and curly  top. The plots were planted on 3 Apr to a density of 142,560 seeds/A, and thinned to 47,520 plants/A on 23 May. Plots were  single rows (22-in. row spacing) and 10 ft long. The experimental design was a randomized complete block design with  eight replications per entry. The field was cultivated on 24 May and 15 Jun. The crop was managed by the grower  according to standard cultural practices. The roots...

Mid-infrared spectroscopic analysis of chemically bound metalcasting sands
Provedor de dados: 18
Autores: Miguel, Roberto E.; Dungan, R.S.; Reeves III, J.B.
Foundries around the world discard millions of tonnes of molding and core sand each year even though they can be beneficially used in manufactured soils and geotechnical applications. Despite their usefulness as an aggregate replacement, some environmental authorities are concerned over potential negative impacts associated with residual organic binders in waste foundry sands (WFSs). In this study, chemically bound molding and core sands were obtained from aluminum, bronze and iron foundries that used alkyd urethane, phenolic urethane, Novolac, and natural organic binders. The aim was to use mid-infrared (MIR) spectrometry to assess changes within the molding and core sands during the casting process, with a specific focus on proximity to the casting...

Uptake coefficients for biosolids-amended dryland winter wheat
Provedor de dados: 18
Autores: Barbarack, K.A.; Ippolito, J.A.; McDaniel, J.
Biosolids regulations developed in the United States employed risk assessment impacts of trace element additions on plant uptake.  The US Environmental Protection Agency adapted the uptake coefficient (ratio of plant concentration to quantity of element added) when developing limitations on selected elemental additions.  The nature of the risk assessment requires uptake coefficients to be constants.  Our hypothesis was the uptake coefficient for copper, iron, molybdenum, nickel, phosphorus, and zinc for biosolids-amended dryland winter wheat decreases with multiple biosolids applications at the same location.  We applied up to 10 applications to two sites (designated North Bennett A and B) in eastern Colorado at rates from 2.24 to 11.2 megagrams per...

Autores: Dungan, R.S.
Airborne microorganisms and microbial byproducts from intensive livestock and manure management systems are a potential health risk to workers and individuals in nearby communities. This report presents information on zoonotic pathogens in animal wastes and the generation, fate, and transport of bioaerosols associated with animal feeding operations and land applied manures. Though many bioaerosol studies have been conducted at animal production facilities, few have investigated the transport of bioaerosols during the land application of animal manures. As communities in rural areas converge with land application sites, concerns over bioaerosol exposure will certainly increase. While most studies at animal operations and wastewater spray irrigation sites...

In the past 200 years, soil science has used reductionist research to develop agricultural technologies that have unlocked the hidden potential of earth's natural systems to feed, clothe, and provide raw materials to the human population of over six billion. The soil quality paradigm seeks to change that scientific approach, the nomenclature of soil science, and institutional priorities for soil management and research. The definition of soil quality is elusive and value-laden. Concerns exist for the paradigm's policy overtones, regional and taxonomic biases, failure to reconcile conceptual contradictions, as well as its ambiguous definitions that are confounded by countless circumstance-specific, function-dependent scenarios. The paradigm does not...

Autores: Lentz, R.D.
Researcher’s seek a more renewable and natural alternative for water soluble anionic polyacrylamide (PAM), a highly-effective, petroleum-derived polymer used in agriculture to control erosion and reduce water seepage from unlined irrigation structures. This study evaluated two anionic polymers: a bacteria-produced polysaccharide (biopolymer) with 10-20 Mg/mol molecular weight (MW) and 30% charge density, and a PAM (12-15 Mg/mol MW, 30% charge density) to compare their ability to flocculate soil colloids, stabilize soil aggregates, and influence effective hydraulic conductivity (seepage loss). The biopolymer most effectively flocculated the colloids at a concentration of 1 mg/L, but was still 30% less effective than PAM at 1 mg/L and 50% less effective than...

In this study, batch sorption and desorption experiments were conducted for testosterone using four agricultural soils and five clay minerals. Significant differences in sorption behavior were observed between abiotic and biotic systems. The Freundlich sorption coefficient Kf (µg per g)/(µg per mL) ranged from 8.53 to 74.46 for soils and from 35.28 to 1243 for clays. The maximum sorption capacity (µg per g) of soils ranged from 25.25 to 440.61 for soils and 168.46 to 499.84 for clays. Correlation of sorption model parameters with soil properties indicated that both clay content and soil organic matter are important variables in predicting testosterone sorption behavior. Observed testosterone desorption from agricultural soils ranged from approximately 14...

Nutrients in Runoff from a Furrow-Irrigated Field After Incorporating Inorganic Fertilizer or Manure.
Provedor de dados: 18
Autores: Lentz, R.D.; Lehrsch, G.A.
Use of dairy manure to supply crop nutrients is gaining broader acceptance as the cost of fertilizer rises; however, there are concerns regarding manure’s effect on water quality. In 2003 and 2004, we measured sediment, NO3-N, NH4-N, K, dissolved reactive P (DRP), and total P (TP) concentrations in runoff from furrow irrigated field plots (6-7 irrigations/y). Annual treatments included: (M) 13 to 34 Mg/ha stockpiled dairy manure; (F) 78 to 195 kg N/ha inorganic N fertilizer; or (C) control--no amendment. Available N in manure applied each year was similar to amounts applied in fertilizer. Constituent concentrations (mg/L) in runoff ranged widely: sediment, 10 to 50,000; NO3-N, 0 to 4.07; NH4-N, 0 to 2.28; K, 3.6 to 46.4; DRP, 0.02 to 14.3; and TP, 0.03 to...

Use of a culture-independent approach to characterize aerosolized bacteria near an open-freestall dairy operation
Provedor de dados: 18
Autores: Dungan, R.S.
Animal manures are known to harbor a variety of zoonotic pathogens, which are suspected of being transported off-site as aerosols from confined feeding operations.  In this study, aerosols were collected using a high-volume sampler downwind from a 10,000 cow open-freestall dairy and nearby fields being sprinkler irrigated with wastewater.  DNA extracts were prepared from the aerosol samples, then a region of the16S ribosomal RNA gene was sequenced for bacterial identification and phylogenetic classification.  At the dairy and irrigation sites, Proteobacteria was the most abundant phylum, representing 78% and 69% of all sequences, respectively, while Actinobacteria, Bacteroidetes and Firmicutes represented only 10% or less of the sequences.  Of the 191...

Ft. Collins sugar beet germplasm evaluated for rhizomania and storage rot resistance in Idaho,  2012
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Panella, Leonard W.
Rhizomania caused by the Beet necrotic yellow vein virus (BNYVV) is a worldwide problem that can lead to loss of tonnage and lower percent sucrose in the field. BNYVV can also reduce the storability of roots. To identify germplasm with resistance to these problems, 18 sugarbeet germplasm lines developed by the USDA-ARS Ft. Collins sugarbeet program and four check cultivars were screened in a field experiment arranged in a randomized complete block design with 6 replications. During the growing season plants were evaluated for foliar rhizomania symptoms. At harvest on 4 October 2012, roots were evaluated for rhizomania symptoms and then placed into an indoor commercial sugarbeet storage building in Paul, ID. Foliar symptoms ranged from 0% for resistant...

Infiltration model for center pivot irrigation on bare soil
Provedor de dados: 18
Autores: King, B.A.; Bjorneberg, D.L.
The marked reduction in infiltration rate caused by formation of a soil surface seal due to water droplet impact on bare soil is a well known phenomenon but is rarely considered in infiltration models, especially under center pivot irrigation.  The objective of this study was to develop a soil infiltration model for center pivot sprinkler irrigation that incorporates the transient reduction in soil surface seal hydraulic conductivity as affected by soil and sprinkler characteristics.  A sealing soil infiltration model was developed using an explicit finite difference solution scheme with a transient soil seal formation model, which is unique from other studies in that it explicitly uses droplet specific power as the driving factor for formation of a soil...

EVALUATION OF BRAVO FOR DISEASE CONTROL IN SEED ALFALFA, 1982: A field with a 3-yr-old stand under irrigation on Portneuf very fine  loam was used for this test. It was typical of seed fields in this area in that lower leaves were lost from shading and disease during the growing season.  Different Bravo rates were applied to field length strips with a tractor mounted sprayed (boom width = 28.5 ft, PTO pump, T-jet 6503 nozzles, 28 psi).  Three consecutive applications were made at, "full bloom" on Jun 27, and then Aug 4, and finally on Aug 27. The treatments were randomized and replicated  4 times. Seed pollinization was enhanced with adequate alfalfa leafcutting bees (Megachile rotundata), taken to the field on Jul 6. Field observations  and a preharvest...

Dairy manure field applications-How much is too much?
Provedor de dados: 18
Autores: Moore, Amber; Ippolito, J.A.
Applying dairy manure to agricultural fields has  been shown to increase crop yields, improve the  water-holding capacity of the soil, and enhance  soil fertility. However, when manures are applied  to fields at high rates over a period of several  years, nutrients can accumulate, causing  eutrophication in drainage waterways; degradation  of drinking water; nutrient toxicities in plants;  nutrient deficiencies in plants; disruptions in  soil microbial populations; and nutritional   imbalances for grazing animals. Growersand dairy   producers also run the risk of violating state and   federal regulations designed toavoid these issues.

Catch-can performance under a line-source sprinkler
Provedor de dados: 18
Autores: Winward, T.W.; Hill, R.W.
A line-source sprinkler configuration provides a linearly decreasing irrigation application rate perpendicular to  the sprinkler line and has been utilized to study crop response to variable irrigation amounts. The effect on measured irrigation  application depths from using various types of catch-cans in those studies is not known. Derived relationships between crop  yield and applied water is dependent on the accuracy of measured catch-can water volumes. The purpose of this study was  to evaluate catch-can characteristic effects on measurement of sprinkler irrigation depths in a line source. This was  accomplished by evaluating six types of catch-cans: (1) 83 mm diameter polypropylene separatory funnel  (with evaporation-suppressing oil), (2) 82 mm...

Autores: Dungan, R.S.
Airborne endotoxin in occupational environments are a potential respiratory hazard to individuals.  In this study, total and inhalable airborne endotoxin samples were collected via filtration from inside animal housing units and downwind from agricultural production sites and a wastewater treatment plant.  Filter extracts were then diluted to examine the effect of interfering substances on the kinetic Limulus amebocyte lysate (LAL) assay.  In most cases, the overall endotoxin concentration was shown to decrease with increasing dilution up to 1,000-fold, suggesting the presence of enhancing substances in the filter extracts.  This dilution dependent effect was most prominent in the inhalable endotoxin samples, while total endotoxin samples displayed little...

Curly top caused by Beet curly top virus is a widespread disease problem vectored by the beet leafhopper in semiarid sugar beet production areas.  Host resistance is the primary defense against this problem, but resistance in commercial cultivars is only low to intermediate.  In order to identify novel sources of curly top resistance, 14 sugar beet lines were screened in a disease nursery in 2015.  The lines were arranged in a randomized complete block design with six replications.  A curly top epiphytotic was created by releasing six viruliferous beet leafhoppers per plant at the four-to six-leaf growth stage on 24 Jun.  Foliar symptoms were evaluated on 13 and 20 Jul using a scale of 0-9 (0 = healthy and 9 = dead) in a continuous manner.  Curly top...

Investigation of copper sorption by sugar beet processing lime waste
Provedor de dados: 18
Autores: Ippolito, J.A.; Strawn, D.G.; Scheckel, K.G.
In the western US, sugar beet processing for sugar recovery generates a lime-based waste product (~250,000 megagrams/yr) that has little liming value in the region’s calcareous soils.  This area has recently experienced an increase in dairy production, with dairies utilizing copper-based hoof baths to prevent hoof diseases.  A concern exists regarding soil copper accumulation as spent hoof baths may be disposed of in waste ponds with pond waters utilized for irrigation.  The objective of this preliminary study was to evaluate the ability of lime waste to sorb copper.  Lime waste was mixed with increasing copper-containing solutions (up to 100,000 mg/kg), at various buffered pH values (6, 7, 8, 9), and shaken over various time periods (up to 30 days)....

Autores: Strausbaugh, C.A.; Eujayl, Imad A.; Rearick, E.; Foote, P.
Rhizomania caused by Beet necrotic yellow vein virus (BNYVV) and storage losses are serious sugar beet production problems.  To identify sugar beet cultivars with resistance to BNYVV and evaluate storability, 24 experimental cultivars were screened by growing them in a sugar beet field infested with BNYVV in Kimberly, ID during the 2011 growing season in a randomized complete block design with 4 replications.  At harvest on 18 October 2011, roots were dug and evaluated for symptoms of rhizomania and also placed in an indoor commercial sugar beet storage building.  Storage samples were evaluated for fungal growth known to correlate with sucrose loss.  Depending on cultivar, surface root discoloration (rot and fungal growth) ranged from 2 to 37%.  Overall,...

The isolates did not produce asexual or sexual spores, had binucleate hyphal cells with clamp connections, grew from 4 to 22 C with and estimated optimal growth at 14.5 C, and formed a dark brown pigment on potato dextrose or malt extract agar amended with 0.5% tannic acid. Color changes observed when solutions of gum guiac, guiacol, and syringaldzine were applied directly to mycelium grown on these...

Excessive copper concentrations in water systems can negatively impact biological systems.  Because copper can form strong associations with organic functional groups, we examined the ability of biochar (a carbon-enriched organic bioenergy by-product) to sorb copper from solution.  In a batch experiment, potassium hydroxide-steam activated pecan shell biochar was shaken for 24 hours in pH 6, 7, 8, or 9 buffered solutions containing various copper concentrations to identify effect of pH on biochar copper sorption.  Afterwards, all biochar solids from the 24 hours shaking period were air-dried and then analyzed using X-ray absorption fine structure spectroscopy to determine solid-phase copper speciation.  In a separate batch experiment, biochar was shaken...

Residual Effects of Fresh and Composted Dairy Manure Applications on Potato Production
Provedor de dados: 18
Autores: Moore D, Amber; Olsen L, Nora; Carey M, Anna; Leytem, A.B.
Potato growers in Idaho and other dairy producing regions often grow potatoes on fields that have had a history of fresh and composted manure applications. Growers remain uncertain of the impacts that previous manure applications will have on tuber yield and quality, as well as diseases, physiological disorders, and contamination by human pathogenic bacteria such as E. coli. The focus of this study was to determine the long term effects of manure, compost, and chemical phosphorus (P) fertilizer applications on tuber yields, tuber quality, nutrient uptake, tuber disorders and diseases, and soil nutrient concentrations. Russet Burbank potatoes were grown in 2008 and 2009 on plots that had received dairy manure, dairy compost, P fertilizer, or no P source...

Soils developed on relict hydrothermally altered soils throughout the Western United States present unique opportunities to study the role of geology on above and belowground biotic activity and composition. Soil and vegetation samples were taken at three unaltered andesite and three hydrothermally altered (acid-sulfate) sites located in and around Lassen Volcanoes National Park in northeastern California. In addition, three different types of disturbed areas (clearcut, thinned, pipeline) were sampled in acid-sulfate altered sites. Soils were sampled (0 to 15 centimeters) in mid-summer 2010 from both under-canopy and between-canopy areas within each of the sites. Soils were analyzed for numerous physical and chemical properties along with soil enzyme...

Addition of activated switchgrass biochar to an aridic subsoil increases microbial nitrogen cycling gene abundances
Provedor de dados: 18
Autores: Ducey, Tom; Ippolito, J.A.; Cantrell, K.B.; Novak, J.M.; Lentz, R.D.
It has been demonstrated that soil amended with biochar, designed specifically for use as a soil conditioner, results in changes to the microbial populations that reside therein. These changes have been reflected in studies measuring variations in microbial activity, biomass, and community structure. Despite these studies, very few experiments have been performed examining microbial genes involved in nutrient cycling processes. Given the paucity of research in this area, we designed a six-month study in a Portneuf soil (coarse-silty, mixed, superactive, mesic Durinodic Xeric Haplocalcid) treated with three levels (1%, 2%, and 10% w/w ratio) of a biochar pyrolyzed from switchgrass (Panicum virgatum) at 350°C and steam activated at 800°C to measure the...

Little is known regarding a soil aggregate's tensile strength response to surfactants that may be applied to alleviate soil water repellency. Two laboratory investigations were performed to determine surfactant effects on the tensile strength of 1) Ap horizons of nine wettable, agricultural soils collected from across the continental U.S., and 2) two of the nine soils (Latahco and Rad silt loams from the Pacific Northwest) that were sampled at two depths (5 and 15 mm) after being sprinkler irrigated. Along with an untreated control, three surfactants (an alkyl polyglycoside, an ethylene oxide/propylene oxide block copolymer, and a blend of the two) were spray applied by hand at rates of 0, 1, 1.63, 3.35, 4.79, or 8.14 kg active ingredient ha1 to 1)...

Effects of Insecticide Seed Treatments Impove Sugarbeet Storability
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Rearick, E.; Eujayl, Imad A.; Foote, P.
Sucrose loss in sugarbeet storage is a concern for all roots, but particularly those stored under ambient conditions.  In order to control or suppress insect issues in sugarbeet production and consequently improve root storability, two neonicotinoid seed treatments, Poncho Beta (60 g a.i. [active ingredient] clothianidin + 8 g a.i. beta-cyfluthrin/100,000 seeds) and Cruiser Tef (60 g a.i. thiamethoxam + 8 g a.i. tefluthrin/100,000 seeds), were used to produce roots from four commercial sugarbeet cultivars grown in Declo, ID.  At harvest, eight-beet samples from each cultivar-treatment combination were collected and placed inside an outdoor pile.  Samples were removed on approximately 30-day intervals beginning on December 6 and 8 in 2008 and 2009,...

Use of Fly Ash as a Liming Material of Corn and Soybean Production on an Acidic Sandy Soil
Provedor de dados: 18
Autores: Tarkalson, D.D.; Shapiro, C.A.; Petersen, J.L.
Fly ash (FA) produced from subbituminous coal combustion can potentially serve as a lime material for crop production in acidic soils. A five-year study was conducted to determine if FA was an effective liming material in an acid sandy soil under corn and soybean grain production. Fly ash and pelletized lime (PL) were surface applied at rates ranging from 3,200 to 6,400 and 1,416 to 5,658 kg/ha (0.5 to 2 times the recommended rate) at two sites near Brunswick, NE, respectively. At Site A, lime source additions increased soil pH by 0.7 units and decreased soil exchangeable Al by 7.3 mg/kg to a depth of 20 cm. Lime applications resulted in pH increase during the first year (2004) at the 0 to 10-cm depth, and in 2007 at the 10 to 20-cm depth. At Site B, soil...

Evaluation of neural network modeling to predict non-water-stressed leaf temperature in wine grape for calculation of crop water stress index
Provedor de dados: 18
Autores: King, B.A.; Shellie, Krista.
Precision irrigation management in wine grape production is hindered by the lack of a reliable method to easily quantify and monitor vine water status.  Mild to moderate water stress is desirable in wine grape for controlling vine vigor and optimizing fruit yield and quality. A crop water stress index (CWSI) that effectively monitors plant water status has not been widely adopted in wine grape because of the need to measure well-watered and non-transpiring leaf temperature under identical environmental conditions. In this study, we calculated a daily CWSI for the wine grape cultivars Syrah and Malbec (Vitis vinifera L.) by estimating well-watered leaf temperature with an artificial neural network (NN) model and non-transpiring leaf temperature based on the...

Increasing the quantitative credibility of open-path FT-IR spectroscopic data with focus on several properties of the background spectrum
Provedor de dados: 18
Autores: Shao, L.; Wang, Wanping; Griffiths, P.R.; Leytem, A.B.
The choice of the type of background spectrum affects the credibility of open-path Fourier transform infrared (OP/FT-IR) spectroscopic data, and consequently the quality of data analysis.  We systematically investigated several properties of the background spectrum.  The results show that a short-path background measured with the lowest amplifier gain could significantly reduce noise in the calculated absorbance spectrum, by at least 30% in our case.  We demonstrated that by using a short-path background, data analysis is more resistant to interferences, such as wavenumber shift or resolution alteration that occurs as a consequence of hardware aging or misalignment.  We also discussed a systematic error introduced into quantitative analyses by the...

An acidic (pH 5.8) biochar was created using a low pyrolysis temperature (350 degrees celsius) and steam activation to potentially improve the soil physicochemical status of an eroded calcareous soil.  Biochar was added at 0, 1, 2, and 10 percent (by weight) to an eroded Portneuf soil (coarse-silty, mixed, superactive, mesic Durinodic Xeric Haplocalcid) and destructively sampled at 1, 2, 3, 4, 5, and 6 month intervals.  Soil was analyzed for volumetric water content, pH, nitrate-nitrogen, ammonium-nitrogen, plant-available iron, zinc, manganese, copper, and phosphorus, organic carbon, carbon dioxide respiration, and microbial enumeration via extractable DNA and 16S rRNA gene copies.  Soil water content increased with biochar application regardless of rate;...

Autores: Carnin, R.L.P; Folgueras, M.V.; Luvizao, R.R.; Correia, S.L.; da Cunha, C.J.; Dungan, R.S.
A fresh green sand, spent green sand, and a weathered spent green sand from a landfill were analyzed using diffractometry, electron microscopy, granulometry, spectrometry, and thermogravimetry.  Our objective was to understand how the physicochemical properties of the green sands change from their original form after being subjected to the casting process, then after weathering at the landfill.  A quantitative phase composition model was also postulated for each material based on thermogravimetric results and it was found to be the most reliable and informative quantitative data for this type of residue.  The weathered sample, that remained in a landfill for two years, was found to be composed of almost pure sand.  Because of the weathering process, it may...

Site-specific management of meloidogyne chitwoodi in Idaho potatoes using 1,3-dichloropropene; approach, experiences, and economics
Provedor de dados: 18
Autores: King, B.A.; Taberna, J.P, Jr.
Fumigation for nematode management in irrigated potato production systems of Idaho is widely practiced. Spatially uniform fumigation with large scale soil injection equipment is the only labeled application method for 1,3-dichloropropene. Plant-parasitic nematode species exhibit spatially variable population densities that provide an opportunity to practice site-specific fumigation to reduce chemical usage and production costs. During 2002-2008, 62 fields intended for commercial potato production in eastern Idaho were sampled using a geo-referenced grid sampling system for plant-parasitic nematode population densities. In total, 4,030 grid samples were collected representing nearly 3200 ha of commercial potato production. Collectively, 73% of the grid...

Inverse dispersion models are useful tools for estimating emissions from animal feeding operations, waste storage ponds, and manure application fields. Atmospheric stability is an important input parameter to such models. The objective of this study was to compare emission rates calculated with a backward Lagrangian stochastic (bLS) inversedispersion model (WindTrax) using three different methods for calculating atmospheric stability: sonic anemometer, gradient Richardson number, and Pasquill-Gifford (P-G) stability class. Ammonia and methane emission data from a compost yard at a 10,000-cow dairy were used for the comparisons. Overall, average emission rates were not significantly different among the stability methods. Emission rates correlated well...

The marked reduction in infiltration rate caused by formation of a soil surface seal due to water droplet impact on bare soil is a well known phenomenon but is rarely considered in infiltration models, especially under center pivot irrigation. The objective of this study was to develop a soil infiltration model for center pivot sprinkler irrigation that incorporates the transient reduction in soil surface seal hydraulic conductivity as affected by soil and sprinkler characteristics. A sealing soil infiltration model was developed using an explicit finite difference solution scheme with a transient soil seal formation model, which is unique from other studies in that it explicitly uses droplet specific power as the driving factor for formation of a soil...

Germplasm Release: Tissue Culture-Derived Curly Top-Resistant Genetic Stock
Provedor de dados: 18
Autores: Eujayl, Imad A.; Strausbaugh, C.A.
The USDA-ARS sugarbeet research program at Kimberly is focused on discovering novel genes for resistance to beet curly top and other economically important diseases.  It is vital in genetics research to develop uniform breeding lines and genetic stocks to study inheritance, gene transfer (through conventional hybridization), and molecular genetics research.  This process requires several one-year inbreeding cycles in sugarbeet because the plant is biennial and the public germplasm has much genetic diversity.  We have adopted a well-established tissue culture approach to develop a type of pure breeding lines called ‘doubled haploid line’ (DHL) from unfertilized ovules. KDH13 (PI663862) genetic stock was released to public breeders and seed companies by the...

Autores: Bjorneberg, D.L.; King, B.A.
Dairy production has expanded in irrigated areas of the western and southwestern US, potentially competing for limited water supplies. Groundwater withdrawal was measured for two years on six dairy farms with 660 to 6400 milk cows in southern Idaho. Groundwater withdrawal was calculated on an equivalent cow basis to account for relative differences in the numbers of milk cows, dry cows, heifers and calves on each farm. Average groundwater withdrawal from each dairy varied from 110 to 250 L/d/eq. cow with an overall average of 190 L/d/eq. cow for the six farms. On an area basis, groundwater withdrawal varied from 180 to 880 mm/y on each farm with a mean of 530 mm/y. Estimated annual irrigation requirements in southern Idaho are 510 mm for spring barley, 590...

Drinking Water Treatment Residuals:  A Reveiw of Recent Uses
Provedor de dados: 18
Autores: Ippolito, J.A.; Barbarick, K.A.; Elliot, H.A.
Coagulants such as alum, [Al2(SO4)3X14H2O], ferric chloride [FeCl3], or ferric sulfate [Fe2(SO4)3] are commonly used to remove particulate and dissolved constituents from water supplies in the production of drinking water.  The resulting waste product, called water-treatment residuals (WTR), contains precipitated Al and Fe oxyhydroxides resulting in a strong affinity for anionic species.  Recent research has focused on using WTR as cost-effective materials to reduce soluble phosphorus (P) in soils, runoff, and land-applied organic wastes (manures and biosolids).  Studies show P adsorption by WTR to be fast and nearly irreversible, suggesting long-term stable immobilization of WTR-bound P.  Because excessive WTR application can induce P deficiency in crops,...

Autores: Lehrsch, G.A.; Kincaid, D.C.
Dairy manure increases the yields of dry bean (Phaseolus vulgaris L.) and  spring wheat (Triticum aestivum L.) from eroded, furrow-irrigated soils and may  increase corn (Zea mays L.) silage yield from steeper eroded areas under sprinkler irrigation.  In a 2-year field study in southern Idaho on Portneuf silt loam (coarse silty,  mixed, superactive, mesic Durinodic Xeric Haplocalcid), the effects of a one-time,  fall application of 29 or 72 Mg ha-1 of dry manure or 22 or 47 Mg ha21 of dry  compost on subsequent silage yield and nitrogen (N) uptake from previously eroded,  sprinkler-irrigated hill slopes were evaluated. In October 1999, stockpiled or  composted dairy manure was disked to a depth of 0.15 m into plots with slopes from  0.8 to 4.4%. After...

With increasing energy and labor  costs, irrigators are looking for ways to  minimize costs and at the same time  use their water more efficiently.  One system used quite extensively  during the past two or three years in  the Grand Valley of Colorado is the  semiautomated "flo-thru" gated pipe  system. This system uses a single  gated pipeline for a number of irrigation  sets without the irrigator having  to close one group of gates and open  another group at each irrigation set  change.

To identify sugar beet cultivars with resistance to BNYVV and evaluate storability, 24 experimental cultivars were screened by growing them in a sugar beet field infested with BNYVV in Kimberly, ID during the 2013 growing season in a randomized complete block design with 4 replications.  At harvest on 11 October 2013, roots were dug and evaluated for symptoms of rhizomania and also placed in an indoor commercial sugar beet storage building.  After 123 days in storage, samples were evaluated for surface rot, weight loss, and sucrose loss.  Surface root rot ranged from 7 to 76%, weight loss ranged from 6.6 to 11.6%, sucrose losses...

Evaluation of sugar beet germplasm for rhizomania and storage rot resistance in Idaho, 2012
Provedor de dados: 18
Autores: Eujayl, Imad A.; Strausbaugh, C.A.
Rhizomania in the field and fungal root rot in storage can both lead to significant sucrose losses in sugar beet roots. In an effort to reduce these losses, sugarbeet germplasm developed by the USDA-ARS Kimberly sugarbeet program was evaluated for resistance to both these disease problems. Nine sugarbeet lines and four check cultivars were arranged in a randomized complete block design with six replications and grown in a field known to be infested with Beet necrotic yellow vein virus (BNYVV), the causal agent of rhizomania. The plants were evaluated for foliar symptoms in July, August, and September. Plots were harvested in October, roots were evaluated for rhizomania root symptoms, and roots from each plot were also placed in a commercial indoor storage...

The importance and challenge of modeling irrigation-induced erosion
Provedor de dados: 18
Autores: Sojka, R.E.; Bjorneberg, D.L.; Trout, T.J.; Strelkoff, T.S.; Nearing, M.A.
Irrigation-induced erosion and rain-induced erosion result from very different  systematics. Therefore, both cannot be predicted effectively using the same models. The  average two-fold yield and three-fold economic advantage of irrigation over rain-fed agriculture,  coupled with the fragility of irrigated land and the strategic importance of irrigation  development to meet world agricultural production needs, has raised the urgency for the  development of robust, accurate, and precise irrigation-induced erosion models. This paper  details the rationale for separate irrigation-induced erosion models, presents essential aspects  unique to irrigation that must be accounted for in the models, and summarizes the progress  (to date) toward the goal of...

Autores: Massey, M.S.; Davis, J; Ippolito, J.A.; Sheffield, R.E.
Magnesium phosphates such as struvite (MgNH4PO4x6H2O) can be recovered from municipal, industrial and agricultural wastewaters.  However, minimal research has been conducted on the beneficial reuse of these recovered products; conducted research has focused on low pH soils.  This study determined whether recovered struvite and dittmarite (MgNH4PO4xH2O) were effective P fertilizers in alkaline soils.  In addition to commercially available triple superphosphate (TSP) and certified organic rock phosphate (RP), recovered struvite, dittmarite, and a heterogeneous recovered phosphate were evaluated in a laboratory dissolution study and as fertilizers for spring wheat (Triticum aestivum L.) in a greenhouse study.  Struvite and dittmarite were much more soluble...

Soil quality indices provide a means of distilling large amounts of data into a single metric that evaluates the soil’s ability to carry out key ecosystem functions. Primarily developed in agroecosytems, then forested ecosystems, we set out to develop and apply an index using the relation between soil organic matter and key soil abiotic and biotic properties in more semi-arid of the Western US arid systems impacted by different geologic mineralization types. We studied these relations in three different mineralization types: serpentine, acid sulfate and Cu/Mo porphyry systems at four different sites in California and Nevada. Soil samples were collected from undisturbed soils in both mineralized and nearby unmineralized terrane as well as waste rock and...

Rhizoctonia root rot causes serious losses on sugar beet worldwide.  In order to help explain why Rhizoctonia root rot management practices have not performed well in some areas of the Intermountain West (IMW), a survey was conducted.  In the IMW from 2004 to 2006, 94 Rhizoctonia solani field isolates were collected from sugar beet roots.  These field isolates were compared with 19 reference strains and 46 accessions from GenBank for genetic diversity based on sequencing of the ITS-5.8S rDNA region.  Greenhouse pathogenicity tests on sugar beet and silage corn were conducted and plant damage was assessed using a randomized complete block design with at least four replications.  The majority (92%) of the isolates had identity with the AG-2-2 IIIB (48%) or...

Nitrogen management recommendations may change as yield levels and efficiency of crop production increase.  The mean yield with adequate nutrient availability in 32 irrigated corn (Zea mays L.) trials conducted across Nebraska to evaluate crop response to split-applied N was 14.8 Mg per ha. The mean economically optimal N rates (EONR) for irrigated corn varied with the fertilizer N to grain price ratio.  At a fertilizer N:corn price ratio of 7, the EONR was 171, 122, and 93 kg per hectare, respectively, for cropping systems with corn following corn (CC), soybean (Glycine max L.) (CS), and drybean (Phaseolus vulgaris L.) (CD).  At this price ratio the present  University of Nebraska (UNL) recommendation procedure gave mean N  recommendations that were 17.2,...

Controlling severe curly top in sugarbeet
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Eujayl, I.A.
Controlling curly top in sugarbeet has been industry priority in the western United States since the 1920s.  Curly top is a virus disease that is vectored by the beet leafhopper.  If the beet leafhopper moves into commercial fields early in the season, virus is more likely to be transmitted to sugarbeet plants at an early growth stage.  However, the plants are more susceptible to the virus at early growth stages.  Thus even if the plants contain host resistance, they sustain considerable damage if infected at an early growth stage.  In order to supplement host resistance insecticide seed treatments were investigated previously and proven to be effective under low to moderate disease pressure.  In the current study under high disease pressure (6...

Evaluation of phosphorus characterization in broiler ileal digesta, manure, and litter samples: 31P-NMR vs. HPLC
Provedor de dados: 18
Autores: Leytem, A.B.; Kwanyuen, P.; Plumstead, P.W.; Maguire, R.O.; Brake, J.
Using 31-phosphorus nuclear magnetic resonance spectroscopy ((31)P-NMR) to characterize phosphorus (P) in animal manures and litter has become a popular technique in the area of nutrient management. To date, there has been no published work evaluating P quantification in manure/litter samples with (31)P-NMR compared to other accepted methods such as high performance liquid chromatography (HPLC). To evaluate the use of (31)P-NMR to quantify myo-inositol hexakisphosphate (phytate) in ileal digesta, manure, and litter from broilers, we compared results obtained from both (31)P-NMR and a more traditional HPLC method. The quantification of phytate in all samples was very consistent between the two methods, with linear regressions having slopes ranging from 0.94...

Rhizoctonia-Bacterial Root Rot Complex in Sugarbeet
Provedor de dados: 18
Autores: Strausbaugh, C.A.
The Rhizoctonia-bacterial root rot complex is a disease problem of concern worldwide in sugarbeet.  A series of studies have been conducted which indicate that the complex is initiated by the fungal pathogen, Rhizoctonia solani.  However, only about 6% of the root mass is lost to the fungal infection and 68-71% of the root mass is lost to subsequent bacterial rot.  The bacterial rot phase of the problem was proven to be initiated by Leuconostoc.  Field studies show that if Rhizoctonia root rot is limited then the bacterial rot phase will be limited as well.  Until we develop a better understanding of this rot complex, control efforts should target Rhizoctonia, since Leuconostoc is naturally widespread in the environment.  Preliminary evidence suggests that...

The expansion of the dairy industry in southern Idaho has lead to increased application of manures to meet crop nutrient demands which can alter the uptake pattern of both macro- and micro-nutrients.  A greenhouse study was conducted to determine the effects of dairy manure, composted dairy manure, and fertilizer (mono-ammonium phosphate, MAP) application on soil test phosphorus (P), microbial activity, and nutrient uptake by silage corn. Two Portneuf soils, having either a low or high soil test P concentration, were amended with the three treatments at four application rates (25, 50, 100, and 200 mg P kg-1) with four replications of each treatment in a randomized complete design. Treatments were incubated for two weeks, then planted with corn grown for...

Provedor de dados: 18
Autores: Ippolito, J.A.; Spackman, R.; Entry, J.A.; Sojka, R.E.
Phosphorus-containing sediment entering surface water may degrade water quality and promote eutrophication.  Grass is sometimes planted as a vegetated filter strip buffer along vulnerable receiving water to trap sediment and reduce the severity of phosphorus nutrient loading.  However, eutrophication is still a problem in some waterways due to dissolved phosphorus leaching from senesced vegetation in grassed areas, independent of trapped sediment.  A rainfall simulator (96 mm/h) was used to study the vegetative conditions under which losses of total dissolved phosphorus and filterable reactive phosphorus leaching are likely.  Boxes containing a Portneuf silt loam soil (Xeric Haplocalcid) were planted with annual ryegrass (Lolium perenne) and cut at two...

Use of standardized procedures to evaluate metal leaching from waste foundry sands
Provedor de dados: 18
Autores: Miguel, Roberto E.; Ippolito, J.A.; Noriega, Roxana B; Dungan, R.S.
As part of the casting process, foundries create sand molds and cores to produce ferrous and non-ferrous metal castings.  After the process, a portion of the sand is discarded and becomes waste foundry sand (WFS). The aim of this study was to quantify metals (i.e. Ag, Ba, Cd, Cr, Cu, Ni, Pb, and Zn) in leaching extracts from a variety of waste molding and core sands from ferrous and non-ferrous foundries using the Extraction Procedure, Toxicity Characteristic Leaching Procedure, and ASTM water extraction procedure. The WFS metal extract concentrations were compared to those found in virgin silica sands and Argentinean and U.S. hazardous waste laws to determine if the WFSs met toxicity limits. The majority of the WFS extracts analyzed, regardless of metal...

Influence of sugarbeet tillage systems on rhizoctonia-bacterial root rot complex
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Eujayl, Imad A.
The Rhizoctonia-bacterial root rot complex on sugarbeet caused by Rhizoctonia solani and Leuconostoc mesenteroides can cause significant yield losses.  To investigate the impact of different tillage systems on this complex, field studies were conducted from 2009 to 2011.  Split blocks with conventional and strip tillage as main plot treatments were arranged in a randomized complete block design with four replications.  Within main plots, there were seven treatments (non-inoculated check and six R. solani AG 2-2 IIIB strains).

Nitrogen and Phosphorus Fertilizer Placement in Corn Production
Provedor de dados: 18
Autores: Tarkalson, D.D.; Bjorneberg, D.L.
The use of strip tillage and other conservation tillage practices are used to conserve soil and soil water through residue management and reduce tillage costs in many areas of the Corn Belt. However, in the Pacific Northwest these tillage practices are less common. Strip tillage is becoming more common in the sugar beet industry in southern Idaho and due to the high dairy cow populations, corn production is increasing. The dual use of strip tillage for sugar beet and corn production will likely continue to develop, increasing the need for strip tillage best management practices in this region. In this study we evaluated the effects of common and logical nitrogen and phosphorus placements with strip tillage and conventional tillage on grain yield on four...

Characterization of physical and chemical properties of spent foundry sands pertinent to beneficial use in manufactured soils
Provedor de dados: 18
Autores: Dayton, E.A.; Whitacre, S.D.; Dungan, R.S.; Basta, N.T.
Abstract As of 2007, of the 2,000 United States foundries, 93% produce ferrous or aluminum castings, generating 9.4 million tons of non-hazardous spent foundry sand (SFS) annually. Only 28% of the SFS is beneficially used. The U.S. EPA Resource Conservation Challenge identifies SFS as a priority material for beneficial use, with soil blending as a potential reuse option. The objectives of this work were to measure: (1) select chemical and physical properties important to soil quality and function and (2) total and soluble elemental content of 39 SFSs, in order to evaluate SFS suitability as a component in manufactured soils. Total elemental concentration of the SFS was lower than natural background soil levels for most elements analyzed, suggesting limited...

Evaluation of Potential Runoff and Erosion of Four Center Pivot Irrigation Sprinklers
Provedor de dados: 18
Autores: King, B.A.; Bjorneberg, D.L.
The operational characteristics of center pivot sprinklers are well documented but few studies have been conducted to evaluate the effects that operating characteristics of a particular sprinkler have on infiltration, runoff, and erosion for specific soil types.  The objective of this study was to evaluate potential runoff and erosion from four commercial center pivot sprinklers on three widely distributed, south central Idaho soils.  A modified commercial irrigation boom system was used to emulate center pivot irrigation on experimental runoff plots.  Sprinklers used in the study were: 1) Nelson R3000 with brown plate, 2) Nelson R3000 with red plate, 3) Nelson S3000 with purple plate, and 4) Senninger I-Wob with standard 9-groove plate.

Differences in irrigation water quality may affect the water repellency of soils treated or untreated with surfactants.  Using simulated irrigations, we evaluated water quality and surfactant application rate effects upon the water repellency of a Quincy sand (Xeric Torripsamment).  We used a split plot design with two irrigation water qualities, three surfactant application rates, two irrigations, and twelve sampling depths as fixed effects, with four replications.  Each water quality x rate x irrigation combination was a main plot and depth was a repeated-measures subplot.  A slightly water repellent Quincy soil (average water drop penetration time, WDPT, of 2.5 s) was packed in 25-mm lifts (or layers) to a bulk density of 1.6 Mg/cubic m into 0.15-m-high...

Root rot in storage can lead to considerable sucrose losses in storage and adversely affect factory processing as well. The use of fungicide treatments applied to the root surface prior to storage were investigated to determine if they could reduce storage rots caused by Botrytis sp., Penicillium sp., and Athelia sp. Roots of the sugar beet cultivar B-5 were produced using standard cultural practices. At harvest eight roots were placed in a mesh onion bags to establish experimental units. The study included nine fungicide treatments (applied as a root dip) and a non-treated check arranged in a randomized complete block design with four replications. Roots were then placed on top of an indoor commercial sugar beet pile and evaluated four times for root rot...

Use of time domain reflectometry for continuous monitoring of nitrate-nitrogen in soil and water
Provedor de dados: 18
Autores: Payero, J.O.; Tarkalson, D.D.; Irmak, S.
Nitrate-Nitrogen (NO3 -N) losses to ground and surface water are an environmental and agronomic concern in  modern crop production systems in the Central Great Plains. Monitoring techniques for nitrogen use in agricultural  production are needed to increase crop yield, optimize nitrogen use, and reduce NO 3 -N leaching. Time domain reflectometry  (TDR) could potentially be calibrated to continuously measure NO3 -N in soil and water. The objectives of this study were to:  (1) evaluate the effect of different factors affecting the response of the bulk electrical conductivity (ECb) sensed by TDR, (2)  compare the sensitivity and differences between vertically-installed and horizontally-installed probes for measuring NO3 -N  leaching in the soil profile, and...

Disease notes - Bacterial root rot
Provedor de dados: 18
Autores: Neher, Oliver T.; Strausbaugh, C.A.
Bacterial root rot initiated by lactic acid bacteria, particularly Leuconostoc, occurs every year in Idaho sugarbeet fields.  Hot fall weather seems to make the problem worse.  Although Leuconostoc initiates the rot, other bacteria and yeast frequently invade the tissue as well.  The acetic acid bacteria, particularly Gluconobacter, are what give the rotted tissue a fermented vinegar-like smell.  The bacteria gain entry into the root through wounds caused by rodents, growth cracks, and fungal lesions such as those associated with Rhizoctonia root rot.  No definite management practices for bacterial root rot in sugarbeet have been established, but minimizing problems with rodents and fungal root rots would be advisable.

Erosion: Irrigation-induced
Provedor de dados: 18
Autores: Lehrsch, G.A.; Lentz, R.D.; Bjorneberg, D.L.; Sojka, R.E.
Soil can be eroded by sprinkler or surface irrigation. Once sprinkler droplet kinetic energy detaches soil, overland flow transports the sediment downslope and off-site. Protecting the soil surface, increasing sprinkler wetted diameters, and tilling to increase infiltration and thereby lessen overland flow are effective control measures. Runoff minimization and management are key to reducing erosion induced by either sprinkler or surface irrigation. Slowing furrow stream velocities with mulch or crop residues reduces the flow’s hydraulic shear and, in turn, detachment of soil from furrow wetted perimeters. Stabilizing surface soil with, for example, polyacrylamide, bio-polymers, or whey keeps soil in place and helps maintains acceptable water quality in...

Sugar beet germplasm and commercial check cultivars were evaluated in a sprinkler-irrigated sugar beet field near Kimberly, ID where sugar beet was grown in 2009. The soil type was Portneuf silt loam. The field trial relied on natural inoculum for rhizomania (caused by Beet necrotic yellow vein virus) development. The seed was treated with clothianidin (2.1 oz a.i. per 100,000 seed) to limit pests and curly top. The plots were planted on 26 Apr to a density of 142,560 seeds/A, and thinned to 47,520 plants/A on 12 Jun. Plots were single rows (22-in. row spacing) and 10 ft long.

Irrigation: Erosion
Provedor de dados: 18
Autores: Bjorneberg, D.L.
Irrigation is essential for global food production. However, irrigation erosion can limit the ability of irrigation systems to reliably produce food and fiber in the future. The factors affecting soil erosion from irrigation are the same as rainfall—water detaches and transports sediment. However, there are some unique differences in how the factors occur during irrigation and in our ability to manage the application of water that causes the erosion. All surface irrigation entails water flowing over soil. Soil type, field slope and flow rate all affect surface irrigation erosion, with flow rate being the main factor that can be managed. Ideally sprinkler irrigation will have no runoff, but application rates on moving irrigation systems can exceed the soil...

Potato cultivar response to seasonal drought patterns
Provedor de dados: 18
Autores: Stark, J.C.; Love, S.; King, B.A.; Marshall, J.M; Bohl, W.H.; Salaiz, T.
The ability to minimize potato yield and quality losses due to drought can be greatly improved by understanding the relative responses of different cultivars to seasonal variations in water supply. To address this need, we initiated a two year field experiment to determine the responses of the six potato cultivars to different seasonal drought patterns, including  1) full season irrigation at 100% ET, 2) irrigation at 100% ET terminated during late bulking , 3) full season irrigation at 70% ET , 4) irrigation at 70% ET terminated during late bulking , and 5) a gradual reduction in irrigation from 100% ET during tuber initiation through early bulking, to 70% ET during mid-bulking, and 50% ET through late bulking.

Concentrations of Airborne Endotoxin and Microorganisms at a 10,000 Cow Open-Freestall Dairy
Provedor de dados: 18
Autores: Dungan, R.S.; Leytem, A.B.; Bjorneberg, D.L.
Confined animal production systems produce elevated bioaerosol concentrations, which are a potential respiratory health risk to individuals on site and downwind. In this study, airborne endotoxin and microorganisms were collected during the spring, summer, and fall at a large  open-freestall dairy in southern Idaho. Compared to the background ambient atmosphere, both endotoxin and culturable heterotrophic bacteria concentrations were up to several-hundred fold greater 50 m downwind from the facility, then decreased to near background concentrations at 200 m. However, downwind fungi concentrations were not elevated above background concentrations. At 50 m downwind, the average inhalable endotoxin concentration ranged from 4.6 to 4243 endotoxin units/cubic...

Little is known about inorganic fertilizer or manure effects on organic carbon (OC) and inorganic C (IC) losses from a furrow irrigated field, particularly in the context of other system C gains or losses. In 2003 and 2004, we measured dissolved organic and inorganic C (DOC, DIC), particulate OC and IC (POC, PIC) concentrations in irrigation inflow, runoff, and percolation waters (6-7 irrigations/y); C inputs from soil amendments and crop biomass; harvested C; and gaseous C emissions from field plots cropped to silage corn (Zea mays L.) in southern Idaho. Annual treatments included: (M) 13 (y 1) and 34 Mg/ha (y 2) stockpiled dairy manure; (F) 78 (yr 1) and 195 kg N/ha (y 2) inorganic N fertilizer; or (NA) no amendment--control.

Rhizoctonia root rot resistance in experimental sugar beet cultivars in Twin Falls County, ID, 2012
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Eujayl, Imad A.
Rhizoctonia root rot continues to be a concerning problem in sugar beet production areas.  To investigate resistance to this disease in 26 experimental sugar beet cultivars, field studies were conducted with three Rhizoctonia solani AG-2-2 IIIB strains.  Based on means for the 26 cultivars, surface rot ranged from 0 to 93% depending on the strain-cultivar combination.  Both the number of dead plants and root surface area rotted resulted in significant (P &lt; 0.0004) cultivar differences.  Based on Spearman’s rank correlation coefficient, there was always a significant relationship (P &lt; 0.0279) when comparing cultivar performance across all three strains regardless of disease variable.  The three most resistant cultivars performed well against all...

Hardwood biochar and manure co-application to a calcareous soil
Provedor de dados: 18
Autores: Ippolito, J.A.; Stromberger, M.E.; Lentz, R.D.; Dungan, R.S.
Biochar may improve nutrient retention when applied to soils, so co-applying biochar with manure may be synergistically beneficial to soils.  In a laboratory incubation study, dairy manure (2% by weight) and a hardwood-based, fast pyrolysis biochar was applied (0, 1, 2, and 10% by weight) to a calcareous soil.  Destructive sampling occurred at 1, 2, 3, 4, 5, 6 and 12 months, and monitored for changes in soil chemistry, water content, microbial respiration, bacterial populations, and microbial community structure.  Increasing biochar application rate improved the soil water content, which may be beneficial in limited irrigation or rainfall areas.  Biochar application increased soil organic carbon content and plant-available iron and manganese, while a...

Soil management and conservation: Irrigation: Methods
Provedor de dados: 18
Autores: Bjorneberg, D.L.
Irrigation applies water to soil to improve crop production. The three main methods of irrigation are surface, sprinkler and micro. Surface irrigation is used on 85% of the irrigated land in the world. It generally requires lower capital investment because the soil conveys water within the field, rather than pipes or tubing used for sprinkler or microirrigation. Water application is more controlled with sprinkler and microirrigation and these irrigation methods can be automated easier than surface irrigation. There are many variations of irrigation methods and types of irrigation equipment. The purpose of this article is to describe the irrigation methods primarily used for agricultural production.

Amending soil with biochar may be a means of sequestering atmospheric CO2 and improving soil quality, but few multiyear field studies have examined the impacts of a one-time biochar application in an irrigated, calcareous soil. We fall-applied four treatments: dairy manure (18.7 tons/ac dry wt.); hardwood-derived biochar (10 tons/ac dry wt.); combined biochar and manure; and no amendments (control). We measured net N-mineralization using buried soil bags and soil greenhouse gas emissions (CO2, CH4, and N2O) from late spring to fall, corn silage yields, and crop N uptake each year. The influence of biochar and manure on silage yield changed with time after application in fall 2008. Biochar increased corn yields slightly (5%) in 2009, decreased yields by 14%...

Curly top caused by Curtovirus species is a widespread disease problem vectored by the beet leafhopper in semiarid sugar beet production areas.  The insecticide seed treatment Poncho Beta has proven to be effective in controlling curly top in sugar beet, but was only evaluated under light to moderate disease pressure.  Thus, the insecticide seed treatments Poncho Beta, NipsIt INSIDE, and Cruiser Force were evaluated under severe curly top pressure (6 viruliferous beet leafhoppers per plant) in field studies during the 2010 and 2011 growing seasons on two commercial sugar beet cultivars.  In addition, the foliar insecticides Movento, Provado, and Scorpion were also evaluated.  The seed treatments and Scorpion reduced curly top symptoms by 33 to 41% (P...

Biochar Usage:  Pros and Cons
Provedor de dados: 18
Autores: Ippolito, J.A.; Lentz, R.D.; Novak M, J; Spokas, K.A.; Collins, H.P.; Streubel, J.
Soil fertility benefits of charcoal application have been reported as early as 1847 indicating that plant nutrients are sorbed within charcoal pores.  The use of biomass-derived black carbon or biochar, the solid byproduct from the pyrolysis processing of any organic feedstock, has garnered recent attention as a potential vehicle for carbon sequestration and a beneficial soil conditioner.  However, most of the past biochar research has focused on improving the physico-chemical properties of tropical (i.e. terra preta) and highly weathered soils, while little research has focused on improving arid or semi-arid soils of the USA.  Here, we present an overview of the potential benefits and drawbacks of biochar usage in western US agro-ecosystems based on...

Strausbaugh, C.A., Panella, L.W. 2016. Beet curly top resistance in USDA-ARS plant introduction lines, 2015
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Panella, Leonard W.
Curly top caused by Beet curly top virus (BCTV) is a widespread disease problem vectored by the beet leafhopper in semiarid sugar beet production areas.  Host resistance is the primary defense against this problem, but resistance in commercial cultivars is only low to intermediate.  In order to identify novel sources of curly top resistance, thirty-one Plant Introduction (PI) Lines were screened in a disease nursery in 2015.  The lines were arranged in a randomized complete block design with three replications.  A curly top epiphytotic was created by releasing approximately 6 viruliferous beet leafhoppers per plant at the four- to six-leaf growth stage on 24 Jun.  Foliar symptoms were evaluated on 13 and 20 Jul using a scale of 0-9 (0 = healthy and 9 =...

Provedor de dados: 18
Autores: Strausbaugh, C.A.; Eujayl, Imad A.; Wambolt, C.
Rhizomania caused by Beet necrotic yellow vein virus (BNYVV) and storage losses are serious sugar beet production problems.  To identify sugar beet cultivars with resistance to BNYVV and evaluate storability, 33 commercial cultivars were screened by growing them in a sugar beet field infested with BNYVV in Kimberly, ID during the 2014 growing season in a randomized complete block design with 6 replications.  At harvest on 24-25 September 2014, roots were dug and evaluated for symptoms of rhizomania and also placed in an indoor commercial sugar beet storage building.  After 138 days in storage, samples were evaluated for surface rot, weight loss, and sucrose loss.  Surface root rot ranged from 7 to 82%, weight loss ranged from 9.4 to 19.1%, sucrose losses...

Provedor de dados: 18
Autores: Strausbaugh, C.A.; Eujayl, Imad A.
Rhizoctonia root rot continues to be a concerning problem in sugar beet production areas.  To investigate resistance to this disease in 26 experimental sugar beet cultivars, field studies were conducted with three Rhizoctonia solani AG-2-2 IIIB strains.  Based on means for the 26 cultivars, surface rot ranged from 0 to 93% depending on the strain-cultivar combination.  Both the number of dead plants and root surface area rotted resulted in significant (P &lt; 0.0004) cultivar differences.  Based on Spearman’s rank correlation coefficient, there was always a significant relationship (P &lt; 0.0279) when comparing cultivar performance across all three strains regardless of disease variable.  The three most resistant cultivars performed well against all...

Autores: Kincaid, Dennis C.
Users of center pivot and lateral move  irrigation systems now have  a wide array of sprinkler packages  from which to choose, including the  traditional overhead impact sprinklers,  various types of spray heads and the  LEPA-type furrow emitters. The original  spray heads used simple, smooth or serrated  fixed deflection plates. Recently, rotating  plate or wobble-plate spray heads have  been developed, combining the advantages  of spray heads and rotating sprinklers  — medium-size pattern radius, good  pattern shape and medium-size droplets  at medium to low pressures (10 to 30 psi).

Water balance for a west and midwest watershed.
Provedor de dados: 18
Autores: Bjorneberg, D.L.; King, K.
Water use efficiency is a term often applied to irrigated conditions to determine the amount of applied water that is used by crops. Water use in irrigated watersheds can be managed by adjusting irrigation diversions to meet irrigation needs. Precipitation is often the only source of water input in many watersheds, and its rate and timing cannot be controlled. Excess water is often drained from the watershed through surface or subsurface drains to provide suitable conditions for crop growth. The objective of this paper is to compare water balances for the irrigated Upper Snake-Rock (USR) watershed in southern Idaho and the subsurface drained Upper Big Walnut Creek (UBWC) watershed in central Ohio. Irrigation water diverted from the Snake River supplied 80%...

Endotoxins are derived from gram-negative bacteria and are a potent inducer of inflammatory reactions in the respiratory tract when inhaled. To assess daily fluctuations of airborne endotoxin and their potential for transport from dairies, endotoxin concentrations were monitored over an 8-h period at upwind (background) and downwind (5 m from edge of dairy) locations on three separate days at two dairies. The dairies consisted of an open-lot or an open-freestall production system, both of which were stocked with 10,000 milking cows.  Upwind concentrations were stable throughout the sampling period, averaging between 1.2 and 36.8 endotoxin units (EU) m-3, whereas downwind concentration averages ranged from 179 to 989 EU-3. Downwind endotoxin concentrations...

Autores: Lehrsch, G.A.
Surfactants may affect soil structure differently depending upon the soil or the quality of rainfall or irrigation water. This study examined whether the water-stable aggregation of 11 wettable soils was affected by surfactants and the water in which the soils were sieved. The study also examined whether the wettable soils’ water drop penetration time (WDPT) was affected by surfactants, water drop quality, and elapsed time since the surfactants were applied. Two nonionic surfactants and a surfactant-free water control were sprayed (by misting) upon air-dry soil, then WDPT was measured 1 and 72 h thereafter. Subsequently, this treated soil was slowly wetted with an aerosol to its water content at a matric potential of 3 kPa, then immediately sieved for 600...

Reducing sucrose loss in sugar beet storage with fungicides
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Neher, Oliver T.; Rearick, E.; Eujayl, Imad A.
Root rots in sugar beet storage can lead to multi-million dollar losses because of reduced sucrose recovery. Thus, studies were conducted to establish better chemical control options and a better understanding of the fungi involved in the rot complex. A water check and three fungicides (Mertect, Propulse, and Stadium) were investigated for their ability to control fungal rot on sugar beet roots held in long term storage during both the 2012 and 2013 storage seasons. At the end of September into October, roots were collected on 5 subsequent weeks, treated, and placed on top of a commercial indoor storage pile until early February. Differences (P &lt;0.0001 to 0.0150) between spray treatments were evident with both Propulse and Stadium reducing fungal growth...

Alarm is expressed about the environmental impact of the increasing amount of reactive N in the atmosphere and in terrestrial and marine ecosystems around the globe. Much of this increase is attributed to production and use of N fertilizer. Use of fertilizer N is essential to meet growing global demand for agricultural commodities. Management is key to increasing productivity while also increasing N use efficiency and reducing N losses. A team of University of Nebraska-Lincoln scientists, with partial funding from the Nebraska State Legislature, addressed this challenge. They conducted 32 irrigated trials across diverse production conditions of Nebraska from 2002 to 2004 to evaluate corn response to rates of split-applied N. The results were reported in...

Autores: Tarkalson, D.D.; Brown, B.; Kok, H.; Bjorneberg, D.L.
Impact of wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) straw removal from fields on soil organic C (SOC) is a concern.  Increased animal populations and potential development of cellulosic ethanol production could increase the removal of straw from fields.  This paper focuses on the effects of wheat and barley straw removal on SOC in irrigated production systems, and related the results to estimates of the minimum straw C inputs required to maintain SOC (MSC) from rain-fed systems. Six studies compared SOC changes with time in irrigated systems in which wheat straw was removed or retained.  These studies indicated that SOC did not decline when residues were removed. Apparently belowground biomass is supplying C to irrigated soils at a rate...

Feed management practices to reduce manure phosphorus excretion in dairy cattle
Provedor de dados: 18
Autores: Kebreab, Ermias; Hansen V, Anja; Leytem, A.B.
Phosphorus (P) is an essential mineral that needs to be supplied in sufficient quantities for maintenance and growth and milk production in dairy cattle. However, over 60% of the P consumed can be excreted in faeces with a potential to cause environmental pollution. Concern over higher levels of P in intensively managed livestock systems has led to legislation such as  the Water Framework Directive in the European Union. In this manuscript, several methods of reducing P pollution are discussed. A major source of environmental P pollution has been overfeeding P mainly due to addition of ‘safety margin’ over the animal’s requirement and concerns related to fertility. Matching the animal’s requirement and feeding in groups so that animals at the same...

Length of efficacy for control of curly top in sugar beet with seed foliar insecticides
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Wenninger, E.J.; Eujayl, Imad A.
Curly top in sugar beet caused by Beet curly top virus (BCTV) is an important yield limiting disease that can be reduced via neonicotinoid and pyrethroid insecticides.  However the length of efficacy of these insecticides is poorly understood, so a series of field experiments was conducted with the seed treatment Poncho Beta (60 g a.i. clothianidin + 8 g a.i. beta-cyfluthrin/100,000 seed) and foliar treatment Asana (55.48 g a.i. esfenvalerate/ha).  A series of four experiments were conducted in 2014 and repeated in 2015 with four treatments (untreated check, Poncho Beta, Asana, and Poncho Beta + Asana) which were arranged in a randomized complete block design with 8 replications.  To evaluate efficacy, viruliferous (contain BCTV strains) beet leafhoppers...

Changes in soil test phosphorus and phosphorus in runoff from calcareous soils receiving manure, compost, and fertilizer application with and without alum
Provedor de dados: 18
Autores: Leytem, A.B.; Bjorneberg, D.L.
Intensification of the dairy industry in southern Idaho had led to the over-application of manures and a buildup of soil phosphorus (P) which is a potential threat to water quality in the region.  As the use of alum has been shown to reduce both soluble manure P and runoff P from alum treated manures, the objective of this study was to determine if surface applications of alum to dairy manure and compost prior to soil incorporation would reduce P losses under furrow irrigation on a calcareous soil. The effects of manure, compost, and fertilizer application with and without alum treatment on soil P, runoff P and aluminum (Al) under furrow irrigation, crop yield, tissue P concentrations and P removal over a four year period were investigated in Kimberly, ID,...

Root rot in sugar beet (Beta vulgaris) causes significant losses worldwide. To assess the distribution of root  rot fungi and their relationship to bacterial root rot,commercial sugarbeet roots with rot symptoms were collected at  harvest time in the Intermountain West. Isolations for both fungi and bacteria were conducted using standard  microbiological techniques, and the root area rotted was assessed. A subset of fungal isolates was tested for  pathogenicity to sugar beet in greenhouse assays and field trials with and without manure. In the field survey of rotting  beets, the fungi most frequently associated with root rot included Fusarium spp. (Fusariumoxysporum and Fusarium  acuminatum with 24% and 15% of isolates, respectively), Geotrichum spp. (16%...

Dairy wastewaters from storage ponds are commonly land applied to irrigate silage crops. Given that diverse microbial populations are associated with cattle feces, the objective of this study was to use a culture-independent approach to characterize Bacteria and Archaea in dairy wastewaters. Using domain-specific primers, a region of the 16S rRNA gene was amplified from pooled DNA extracts from 30 dairy wastewaters and subsequently used to create a clone library. A total of 152 bacterial clones were examined and sequence matches were affiliated with the following groups: Actinobacteria, Bacteroidetes, Firmicutes, Proteobacteria, and Synergistetes. Firmicutes was identified as the largest phylum representing up to 69% of the clone sequences. Of 167 clones...

Russian wildrye nutritive quality as affected by accession and environment
Provedor de dados: 18
Autores: Karn, J.F.; Mayland, H.F.; Berdahl, J.D.; Asay, K.H.; Jefferson, P.G.
High-quality forage for spring and fall grazing is an important need of ranchers  in the Northern Great Plains and Intermountain-West regions of the United States of America and in the prairie provinces of Canada.  Russian wildrye [Psathyrostachys juncea (Fischer) Nevski] has been used to meet this grazing need, especially in Canada. However, its  use has probably been limited by its reputation for seedling establishment difficulties and scattered reports of grass tetany. The purpose  of this research was to characterize the variation in nutritive quality of Russian wildrye accessions used in a multi-location grass tetany  project, to access the effect of environment on quality components, and to determine the relationship between forage nutritive quality...

Estimation of infectious risks in residential populations exposed to airborne pathogens during center pivot irrigation of dairy wastewaters
Provedor de dados: 18
Autores: Dungan, R.S.
In the western United States where dairy wastewaters are commonly land applied, there are concerns over individuals being exposed to airborne pathogens. In response, a quantitative microbial risk assessment (QMRA) was performed to estimate infectious risks after inhalation exposure of pathogens aerosolized during center pivot irrigation of diluted dairy wastewaters. The dispersion of pathogens (Campylobacter jejuni, Escherichia coli O157:H7, non-O157 E. coli, Listeria monocytogenes, and Salmonella spp.) was modeled using the atmospheric dispersion model, AERMOD. Pathogen concentrations at downwind receptors were used to calculate infectious risks during one-time (1, 8, and 24 h) and multi-day (7 d at 1 h/d) exposure events using a Beta-Poisson...

What is new with rhizomania and curly top management and effects of these viruses on storage
Provedor de dados: 18
Autores: Strausbaugh, C.A.
Rhizomania is a serious yield limiting viral disease in sugarbeet first identified in California, USA in 1984.  The disease has since spread to all major production areas in the United States.  Rhizomania is caused by Beet necrotic yellow vein virus (BNYVV) and vectored by the plasmodiophorid (a fungal-like organism), Polymyxa betae.  The virus survives inside the thick-walled resting spore of the vector in the soil, which can remain viable for many years.  As a result, once a field is infested, using crop rotation and non-host crops will not be effective for controlling the disease.  In the spring with near saturated soil conditions, the resting spore will germinate to release zoospores when in close proximity to sugarbeet roots.  The zoospores will...

Year-Long Assessment of Airborne Endotoxin at a Concentrated Dairy Operation
Provedor de dados: 18
Autores: Dungan, R.S.; Leytem, A.B.; Bjorneberg, D.L.
In this study, we monitored total airborne endotoxins at upwind and downwind sites at a large open-lot dairy each month for a year. At the upwind site, the average airborne concentration was 28.5 endotoxin units (EU) m-3, while at the downwind edge of the lot and 200 m from the lot edge, the average concentrations were 169 and 72 EU m-3, respectively. At the downwind edge of the lot, there was a significant correlation between the airborne endotoxin concentration and wind speed or air temperature. A comparison between total and inhalable airborne endotoxin concentrations, near the end of the study, revealed no significant differences between the two endotoxin collection methods. Our data suggest that endotoxin exposure can be reduced as one increases their...

Provedor de dados: 18
Autores: Strausbaugh, C.A.; Camp, S.
Experimental sugar beet cultivars were evaluated in a commercial sprinkler-irrigated sugar beet field near Heyburn,  ID where winter wheat was grown in 2005. The field trial relied on natural infection of Verticillium dahliae. The plots were  planted on 28 Apr to a density of 142,560 seeds/A, and thinned to 47,520 plants/A on 15-20 Jun. Plots were four rows wide  (22-in. row spacing) and 34.5 ft long. The experimental design was a randomized complete block design with eight  replications per cultivar. The field was cultivated on 8 and 20 Jun. The crop was managed by the grower according to  standard cultural practices. The percentage of plants with leaves that had dead vein delimited sectors was recorded for the  center two rows on 6 Sep. The center two...

Transient Soil Surface Sealing and Infiltration Model for Bare Soil Under Droplet Impact.
Provedor de dados: 18
Autores: King, B.A.; Bjorneberg, D.L.
The marked reduction in infiltration rate caused by formation of a soil surface seal due to water droplet impact on bare soil is a well known phenomenon but is rarely considered in infiltration models, especially under center pivot irrigation.  Water application rates under center pivot irrigation commonly exceed infiltration rate, especially near the end of the system lateral.  This can lead to off-site runoff and erosion, but more importantly results in field-scale non-uniform water infiltration that can substantially reduce water use efficiency of these irrigation systems.  The objective of this study was to develop a sealing soil infiltration model that considers transient soil seal formation on a 30 min or less time scale and can potentially be...

Beet curly top resistance in USDA-ARS Plant Introductions, 2013
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Panella, Leonard W.
Curly top caused by Curtovirus species is a widespread disease problem vectored by the beet leafhopper in semiarid sugar beet production areas. Host resistance is the primary defense against this problem but resistance in commercial cultivars is only low to intermediate. In order to identify novel sources of curly top resistance, thirty Plant Introduction (PI) Lines were screened in a disease nursery in 2013. The lines were arranged in a randomized complete block design with three replications. A curly top epiphytotic was created by releasing approximately 6 viruliferous beet leafhoppers per plant at the four- to six-leaf growth stage on 27 Jun. Foliar symptoms were evaluated on 16 Jul using a scale of 0-9 (0 = healthy and 9 = dead) in a continuous manner....

Autores: Dungan, R.S.; Leytem, A.B.
Endotoxins are derived from gram-negative bacteria and are  a potential respiratory health risk for animals and humans. To  determine the potential for endotoxin transport from a large  open-lot dairy, total airborne endotoxin concentrations were  determined at an upwind location (background) and five  downwind locations on three separate days. The downwind  locations were situated at of the edge of the lot, 200 and 1390  m downwind from the lot, and downwind from a manure  composting area and wastewater holding pond. When the  wind was predominantly from the west, the average endotoxin  concentration at the upwind location was 24 endotoxin units  (EU) m?3, whereas at the edge of the lot on the downwind side  it was 259 EU m?3. At 200 and 1390 m downwind...

Laser precipitation monitor for measurement of drop size and velocity of moving spray-plate sprinklers
Provedor de dados: 18
Autores: King, B.A.; Winward, T.W.; Bjorneberg, D.L.
Sprinkler drop size distribution and associated drop velocities have a major influence on sprinkler performance in regards to application intensity, uniformity of water application, wind drift, evaporation losses and kinetic energy transferred to the soil surface.  Sprinkler drop size measurements are either labor intensive or require use of expensive equipment, both of which limit data availability.  Sprinkler drop velocity data are more limited than drop size data due to measurement difficulty and associated cost of labor and instrumentation.  An economical laser instrument commercially marketed for real-time rainfall measurements as a Laser Precipitation Monitor (LPM) was used to measure drop size and velocity from ten moving spray-plate type...

Sugar beet (Beta vulgaris) varieties were evaluated for disease resistance to curly top to establish  if disease ratings made in inoculated nurseries correlated with disease ratings and yield in sugar  beet crops exposed to natural disease outbreaks. Cultivars were planted both in inoculated curly  top nurseries in Kimberly, ID, and in commercial cultivar trials in irrigated fields near Ontario,  OR and Nampa, ID. Plants were evaluated for curly top using a rating scale of 0 (no symptoms)  to 9 (dead). Moderate disease pressure in the Ontario (mean rating = 3.8) and Nampa (mean  rating = 4.1) fields resulted in significant differences for disease rating, root yield, sugar content,  and estimated recoverable sugar among cultivars.

Yield response of corn to deficit irrigation in a semiarid climate
Provedor de dados: 18
Autores: Payero, J.O.; Melvin, S.R.; Irmak, S.; Tarkalson, D.
Irrigation water supplies are decreasing in many areas of the US Great Plains, which is  requiring many farmers to consider deficit-irrigating corn (Zea mays L.) or growing crops like  winter wheat (Triticum aestivum L.) that require less water, but that are less profitable. The  objectives of this study were to: (1) quantify the yield response of corn to deficit irrigation,  and (2) determine which of several seasonal water variables correlated best to corn yield in a  semiarid climate. Eight (T1-T8) and nine (T1-T9) deficit-irrigated treatments (including  dryland), were compared in 2003 and 2004 in North Platte, Nebraska. The actual seasonal  crop evapotranspiration (ETd) (calculated with procedures in FAO-56) for the different  treatments was 37-79% in...

Evaluation of Beta corolliflora for resistance to curly top in Idaho
Provedor de dados: 18
Autores: Gillen, A.M.; Strausbaugh, C.A.; Tindall, K.V.
Curly top of sugarbeet is caused by Beet severe curly top  virus (BSCTV) or closely related curtovirus species which  are vectored by the beet leafhopper (Circulifer tenellus).  Beta corolliflora, shown in 1969 to impart a very high level  of curly top resistance to sugarbeet into the BC2 generation,  is a wild relative of cultivated sugarbeet that has not  been utilized in breeding programs. The nature of curly top  resistance from B. corolliflora seems to be reduced symptoms  and resistance to viral accumulation. Field screening  of 14 B. corolliflora accessions for resistance to curly top  followed by PCR detection of BSCTV did not identify any  accessions with phenotypic symptoms of curly top and 9  accessions did not have detectable virus.

Aluminum-based water treatment residual use in a constructed wetland for capturing urban runoff phosphorus: Column study
Provedor de dados: 18
Autores: Ippolito, J.A.
Aluminum-based water treatment residuals (Al-WTR) have a strong affinity to sorb phosphorus.  In a proof-of-concept greenhouse column study, Al-WTR was surface-applied at 0, 62, 124, and 248 Mg/ha to 15 cm of soil on top of 46 cm of sand; Al-WTR rates were estimated to capture 0, 10, 20, and 40 years of phosphorus from an urban watershed entering an engineered wetland in Boise, Idaho, USA.  Creeping red fescue (Festuca rubra) was established in all columns; one set of columns received no Al-WTR or plants.  After plant establishment, once per week over a 12-week period, ~1.0 pore volumes of ~0.20 mg phosphorus/L was added to each column.  Infiltration rates were measured, leachate was collected and analyzed for soluble phosphorus, and fescue yield,...

Provedor de dados: 18
Autores: Tarkalson, D.D.; Kachman, S.D.; Knops, J.M.N.; Thies, J.E.; Wortmann, C.S.
Results of a previous laboratory study indicated that six transgenic crops expressing the Cry1Ab insecticidal protein from Bacillus thuringiensis (Bt) decomposed at a slower rate than their respective non-Bt isolines. Consequently, litter decomposition rates, nitrogen cycling, and carbon pools may change in agricultural systems as the result of the widespread use of Bt crops. In this study, we assessed the decomposition rates and chemical composition of commonly grown hybrids of Bt and non-Bt isolines of corn (Zea mays L.) in the field. Leaves, stalks, and cobs from two Bt corn hybrids (Pioneer 34N44 Bt and NC+ 4990 Bt) and their non-Bt isolines (Pioneer 34N43 and NC+ 4880) were analyzed for biomass fractions (soluble, hemicellulose, cellulose, and lignin)...

Autores: Tarkalson, D.D.; Eujayl, Imad A.; Beyer, Werner; King, B.A.
Increased water demands and drought have resulted in a need to indentify crop hybrids that are drought tolerant, requiring less irrigation to sustain yields. This study was conducted to assess differences in drought tolerance among a group of genetically diverse sugarbeet hybrids. The study was conducted over three consecutive growing seasons (2008-2010) at the USDA Northwest Irrigation and Soils Research Laboratory in Kimberly, Idaho on a Portneuf silt loam soil (coarse-silty, mixed, superactive, mesic Durinodic Xeric Haplocalcid). Drought tolerance was evaluated by measuring sucrose yield production of six breeding hybrids of Klein Wanzlebener Saatzucht (KWS SAAT AG) and one commercial hybrid (Betaseed Inc.) under six water input treatments.

Provedor de dados: 18
Autores: Lehrsch, G.A.; Brown, B.; Lentz, R.D.; Johnson-Maynard, J.L.; Leytem, A.B.
Adequate characterization of nitrogen (N) mineralization with time from manure and other organic sources is needed to maximize manure N use efficiency, decrease producer costs, and protect groundwater quality.  The objective of our two-year field study at Parma, ID, was to quantify in situ N mineralization with time as affected by a one-time fall application of solid dairy manure, either composted or stockpiled.  The experiment included five treatments: a non-N fertilized control, two first-year rates of stockpiled solid dairy manure (21.9 and 43.8 Mg/ha, dry wt.) and two rates (53.1 and 106.1 Mg/ha, dry wt.) of composted dairy manure (hereafter termed compost).  Net N mineralization (mineralization less immobilization) was determined to a depth of 0.3 m...

Autores: Dungan, R.S.; Leytem, A.B.; Verwey, S.; Bjorneberg, D.L.
Increased bioaerosol loadings in downwind plumes from concentrated animal feeding operations (CAFOs) may increase the risk for allergy and infection in humans. In this study we monitored airborne concentrations of culturable bacteria and fungi at upwind (background) and downwind sites at a 10,000 milking cow dairy over the course of a year. The average bacterial concentrations at the upwind site were 8,400 colony forming units (CFU)/cubic meter and increased to 990,000 CFU/cubic meter at the downwind edge of the cattle pens, decreasing to 63,000 CFU/cubic meter 200 m farther downwind. At the same sites, the average fungal concentrations were 515, 945, and 1010 CFU/cubic meter, respectively. Significant correlations between the ambient weather data and...

Biochar can positively influence soil moisture relations
Provedor de dados: 18
Autores: Ippolito, J.A.; Levine, Jonah; Williams, Morgan.
One major issue related to climate change is the potential to improve soil water relations in light of changes in future precipitation patterns or reductions in water availability in drier portions of the world (such as the western US).  It appears that biochar may play a positive role, but that role may be soil texture related.  We performed a study with a sandy (Wolverine sand from Shelley, ID), silty (Portneuf silt loam from Kimberly, ID), and clay loam soil (Danville clay loam from a subsurface horizon, from near Oakland, CA) that received either 5 or 10% by volume of lodgepole biochar in either chipped (0.25-0.63”) or fine (0-0.25”) form; a control (no biochar) was also included.  Soil-biochar treatments were evenly mixed and placed into containers,...

Effects of Planting Configuration and In-Row Plant Spacing on Photosynthetic Active Radiation Interception for Three Irrigated Potato Cultivars
Provedor de dados: 18
Autores: Tarkalson, D.D.; King, B.A.; Bjorneberg, D.L.; Taberna, J.P, Jr.
Research studies have evaluated the production of potatoes (Solanum tuberosum L.) grown in conventional and bed planting configurations. However, intercepted photosynthetically active radiation (PAR) from these planting configurations has not been quantified. A study conducted in 2008 and 2009 quantified and compared the intercepted PAR from three planting configurations (four row conventional ridged-row [4RC], five row bed [5RB], and seven row bed [7RB]), and from different plant spacings of cvs Russet Burbank, Russet Norkotah, and Ranger Russet potatoes under sprinkler irrigation. A second study was conducted in 2007 to evaluate the relationship between PAR and leaf area of Russet Norkotah and Russet Burbank for the three planting configurations. These...

Impact of sheep bedding on soil nutrient dynamics in the Centennial Mountains of Montana and Idaho
Provedor de dados: 18
Autores: Leytem, A.B.; Seefeldt, S.S.
Sheep and lamb production is an important industry in Idaho, with  summer sheep grazing in the mountains a common practice. Sheep are  concentrated in bedding areas at night leading to concentrated grazing  and manure and urine accumulation in these areas. To address the effects  of bedding on soil nutrient status, we monitored 16 bedding areas in the  Centennial Mountains, with a general survey performed in 2004 followed  by more intense monitoring of six sites from 2005 to 2006. In 2004, soils  were analyzed for total carbon (C) and nitrogen (N), organic C, total P,  Olsen P, water-soluble phosphorus (WSP), soluble nitrate, and soluble  ammonium. Over the period 2005–2006, soils were analyzed for soluble  nutrients including Olsen P, WSP, soluble...

Sprinkler Irrigation Effects on Infiltration and Near-Surface Unsaturated Hydraulic Conductivity
Provedor de dados: 18
Autores: Lehrsch, G.A.; Kincaid, D.C.
Sprinkler irrigation alters soil hydraulic properties both at and below the soil surface, yet its effects are not well characterized. We evaluated the effects of sprinkler irrigation on infiltration and near‐surface hydraulic conductivity (K) measured under tension in a poorly structured, recently roller‐harrowed Portneuf silt loam (Durinodic Xeric Haplocalcid). The experimental design was a randomized complete block with two treatments (pre‐ and post‐irrigation) and four replications. We used two half‐circle spray heads to apply 127 mm of water at 70 mm h-1 in one irrigation to duplicate 1 × 2 m plots. Unconfined (three‐dimensional) infiltration rates at steady‐state were measured at potentials of -55, -35, and -15mm of water before and about 10 days...

Predicting soil-extractable Zn, P, Fe, and Cu in a biosolids-amended dryland wheat agroecosystem
Provedor de dados: 18
Autores: Barbarack, K.A.; Ippolito, J.A.
Biosolids Beneficial Use Programs frequently involve multiple applications at agronomic rates, with plant-nutrient availability changing as elements react with soil constituents over time. Consequently, can regression equations reasonably estimate plant availability of Zn, P, Fe, and Cu, where multiple applications of Littleton and Englewood, Colorado Wastewater Treatment Plant biosolids are applied to a dryland wheat (Triticum aestivum L.)-fallow agroecosystem? Before each growing season, we added Littleton and Englewood biosolids at rates of 0 to 11.2 dry Mg ha?1 to plots arranged in randomized complete blocks with four replications per treatment. Soil samples collected after each wheat harvest were analyzed using an NH4HCO3-diethylenetriaminepentaacetic...

Nutrient excretion, phosphorus characterization, and phosphorus solubility in excreta from broiler checks fed diets containing graded levels of wheat distillers grains with solubles
Provedor de dados: 18
Autores: Leytem, A.B.; Kwanyuen, P.; Thacker, P.A.
Increased interest in ethanol production  in North America has led to increased production of  distillers dried grains with solubles (DDGS), the majority  of which are fed to livestock. To determine the  impact of including wheat DDGS in broiler diets on  nutrient excretion and P characterization and solubility,  125 one-day-old male broiler chicks were fed wheat and  soybean meal-based diets containing 0, 5, 10, 15,  or 20% wheat DDGS. There were 5 replicate pens per  treatment, with 5 birds per pen arranged in a randomized  block design. Apparent retention of both N and  P were determined by using the indicator method.  Nutrients excreted per kilogram of DM intake were  also calculated. Characterization of excreta P was determined  by 31P-solution...

Dietary low-phytate mutant-M 955 barley grain alters phytate degradation and mineral digestion in sheep fed high-grain diets
Provedor de dados: 18
Autores: Leytem, A.B.; Taylor, J.B.; Raboy, V.; Plumstead, P.W.
Greater production demands for ruminants require increased dietary inclusion of high-energy feeds. Grains and oil seeds are most commonly used to enhance diet energy density. However, use of such feeds proportionally increases the amount of dietary phytate phosphorus (P), which the ruminant may not be able to fully utilise. Our objectives for this study were to determine the extent of phytate degradation and mineral digestion in wethers fed high-grain diets consisting of either a non-mutant or low-phytate mutant barley grain. In two separate experiments, mature Columbia wethers (n = 7) fitted with rumen and duodenal cannulas and Columbia × Polypay wether lambs (n = 8) were individually fed one of two finishing diets formulated with either non-mutant...

Autores: Koehn, A.C.; Lehrsch, G.A.; Busscher, W.J.; Evans, D.E.; King, B.A.; Stieneke, D.L.; Sojka, R.E.
Agricultural crops grown in southern Idaho are furrow or sprinkler irrigated. Therefore, the soil experiences several wetting and drying cycles each growing season that can contribute to changes in aggregate tensile strength and friability. The objective of the research was to evaluate the influence of irrigation on soil structural properties. Four furrow irrigated fields were sampled at the top and bottom of the field, in the furrow and on the bed location of the furrow. Five sprinkler irrigated fields were sampled at 0-5 and 5-15 cm depth and at the top and bottom of the field. Results from this study indicate that differences in tensile strength in furrow irrigated fields were only evident soon after irrigation; otherwise, there were few differences in...

Autores: Ippolito, J.A.; Laird, D.A.; Busscher, W.J.
Understanding and improving environmental quality by reducing soil nutrient leaching losses, reducing bioavailability of environmental contaminants, sequestering C, reducing greenhouse gas emissions, and enhancing crop productivity in highly weathered or degraded soils, has been the goal of agroecosystem researchers and producers for years.  Biochar, produced by pyrolysis of biomass, may help attain these goals.  The desire to advance understanding of the environmental and agronomic implication of biochar utilization led to the organization of the 2010 ASA-CSSA-SSSA Environmental Quality Division session entitled Biochar Effects on the Environment and Agricultural Productivity (Long Beach, CA; Oct. 31-Nov. 3).

Autores: Leytem, A.B.; Dungan, R.S.; Bjorneberg, D.L.
The volatilization of NH3 from dairy production facilities is not only a loss of valuable N, but also an air quality concern because NH3 plays a role in the formation of airborne particulate matter, which can be a health hazard. The ambient NH3 concentrations over several seasons at 3 locations (open lots, compost yard, lagoon) throughout a large openlot dairy were determined, as well as the spatial distribution of NH3 over the open-lot area. There was a significant main effect of location (P &lt; 0.0001), which followed the trend of lot &gt; lagoon = compost &gt; background, with averages of 0.58, 0.33, 0.30, and 0.04 mg NH3/m3, respectively. The effect of weather and lot conditions on the spatial distribution of NH3 across the lots was evident, with...

To further expand biochars utility, ARS scientists have collaborated with United States Environmental Protection Agency (US EPA) investigators to reclaim mine-impacted soils. In the agronomic investigations, both positive and negative aspects of biochar application were revealed.  In some experiments,...

Manure and fertilizer effects on carbon balance and organic and inorganic carbon losses for an irrigated corn field
Provedor de dados: 18
Autores: Spokas, K.A.; Novak, J.M.; Masiello, C.A.; Johnson, M.G.; Colosky, E.C.; Ippolito\, J.A.
Data collected from both artificially and field (naturally) weathered biochar suggest that a potentially significant pathway of biochar disappearance is through physical breakdown of the biochar structure. Through scanning electron microscopy (SEM) we characterized this physical weathering which increased structural fractures and possessed higher numbers of liberated biochar fragments. This was hypothesized to be due to the graphitic sheet expansion accompanying water sorption coupled with comminution. These fragments can be on the micro and nano-scale, but are still carbon-rich particles with no detectable alteration in the oxygen to carbon ratio of the original biochar. However, these particles are now easily dissolved and could be moved by infiltration....

In-field rates of decomposition and microbial communities colonizing residues vary by depth of residue placement and plant part, but not by crop genotype for residues from two Cry1AB Bt corn hybrids and their non-transgenic isolines.
Provedor de dados: 18
Autores: Londono-R, L; Tarkalson, D.D.; Thies, Janice E.
The adoption of Bt corn has been largely overshadowed by concerns about their unintended effects on human health and the environment. Residues of transgenic Bt crops decomposed more slowly than their non-transgenic isolines in one laboratory study, although no mechanism to explain these observations was proposed. If Bt crop residues were to decompose more slowly in field soils, changes in carbon cycling and nutrient availability could result. We compared the in-field decomposition rates and diversity of decomposers colonizing residues of two Cry1Ab Bt corn hybrids, active against the European corn borer, with their non-transgenic isolines in litterbags placed in a Nebraska field. After five months, we found no significant differences in either the rates of...

Bacterial root rot of sugarbeet (Beta vulgaris) caused by Leuconostoc mesenteroides subsp. dextranicum is a disease problem recently described in the Intermountain West region of the United States. To ameliorate the impact of bacterial root rot on sucrose loss in the field, storage piles, and factories, studies were conducted to establish an assay for identifying host resistance. In 2006 and 2007, 21 commercial cultivars were evaluated in a petri dish laboratory assay. Root slices were inoculated with L. mesenteroides and the diameter of the rotted area was measured after 72 and 96 h. The cultivars were arranged in a randomized complete block design with 4 replications. With 2006 roots after 96 h, the average rot diameter ranged from 16 to 34 mm (LSD = 5)...

Managing Runoff Water Quality From Recently Manured, Furrow Irrigated Fields
Provedor de dados: 18
Autores: Lentz, R.D.; Westermann, D.T.
Nutrient losses in furrow irrigation runoff potentially increase when soils are amended with manure. We evaluated the effect of tillage, water soluble polyacrylamide (WSPAM) and irrigation management on runoff water quality during the first furrow irrigation on a calcareous silt loam soil, which had received 45 Mg/ha (dry wt.) dairy manure applied in the fall. In Exp. 1 the amended soil was rototilled and irrigated that fall; furrow inflows were either treated with 10 mg/L WSPAM injected into furrow inflows only during furrow advance (Fall-WSPAM), or were untreated (Fall-Control). In Exp. 2 the first irrigation on the amended soil was delayed until the following spring and treatments included rototilled WSPAM (Spring-WSPAM) and untreated rototilled...

Adoption of new management techniques which improve soil water storage and soil nitrogen  plant availability yet limit nitrogen leaching may help improve environmental quality.  A benchtop study was conducted to determine the influence of a single urea fertilizer rate (224 kilograms of Nitrogen per hectare) applied with band or fully-mixed zeolite (Clinoptilolite) application rates (up to 90 megagrams per hectare) on ammonium-nitrogen and nitrate-nitrogen concentrations in a Portneuf silt loam.  Two additional greenhouse experiments were carried out to test the soil moisture status and corn growth in a Wolverine sand.  Mixing urea fertilizer into silt loam soil resulted in greater urea mineralization, but the mixed zeolite was more effective at adsorbing...

Delayed sample filtration and storage effects on dissolved nutrients measured in agricultural runoff
Provedor de dados: 18
Autores: Lentz, R.D.
Standard water quality analysis methods recommend that sediment-laden runoff waters sampled to determine dissolved nutrient concentrations be filtered immediately after collection.  Few research studies have examined the influence of delayed filtration on sample stability or nutrient loss assessments.  Twenty eight runoff water volumes were collected from 3 irrigation furrows during a 12-h irrigation set.  Four subsamples of each volume were obtained; 2 were filtered (45 µm) in the field and the other 2 were filtered 10 days later, with or without boric acid treatment (1 mL saturated H3BO3 solution per 100 mL sample). All samples were refrigerated at 4 deg. C.  Dissolved reactive P (DRP), NO3-N, and NH4-N concentrations were measured in all filtered...

Evaluating the surface irrigation soil loss (SISL) model
Provedor de dados: 18
Autores: Bjorneberg, D.L.; Prestwich, C.J.; Evans, R.G.
Although the percentage of surface irrigated land in  the United States is declining, it is still used on  43% of the irrigated land, and 51% of the surface  irrigated land is irrigated down furrows or rows  (USDA, 2004). Water flowing in irrigation furrows often detaches  and transports soil, reducing crop productivity and impairing  off-site water quality. Crop yields were at least 25%  less on fields eroded from over 80 years of furrow irrigation  in south-central Idaho (Carter et al., 1985). Measured soil  loss from furrow irrigated fields in this area varied from 1 to  141 Mg ha-1 annually (Berg and Carter, 1980) while the annual  average soil loss from the entire irrigated tract was 0.46 Mg  ha-1 in 1971 (Brown et al, 1974). This soil, and associated...

Fifteen Years of Wheat Yield, N Uptake, and Soil Nitrate-N Dynamics in a Biosolids-Amended Agroecosystem. Agriculture, Ecosystems and Environment
Provedor de dados: 18
Autores: Barbarick, K.A.; Ippolito, J.A.; McDaniel, J.P.
Understanding N dynamics in biosolids-amended agroecosystems can help avoid over-application and the potential for environmental degradation. We investigated 15-years of biosolids application to dryland-wheat, questioning what is the relationship between cumulative grain yield and N uptake (N removal) and biosolids or N fertilizer rates and how many times biosolids or N fertilizer are applied? How are wheat-grain production and N uptake intertwined with residual soil nitrate-N? We found that biosolids or N fertilizer rates plus the number of applications of each material produced planar-regression (3-dimensional) models with 15-years of grain yield and N uptake data (all R2 &gt; 0.93). To evaluate how yield or N uptake impacted residual soil nitrate-N, we...

Automatic Water Control Structures for Surface Irrigation (Summarized)
Provedor de dados: 18
Autores: Humpherys, A.S.
Many improvements have been made in irrigation methods  and equipment in recent years. However, surface irrigation has not benefited from automation and still requires much hand labor. In addition to this high labor requirement, an excessive amount of water is often used. This is particularly true in areas where water is relatively cheap and labor is scarce. Further improvement in surface  irrigation methods and equipment using mechanized automated  control structures will enable the farmer to apply water with a  minimum of labor and to obtain maximum use from the water, thus conserving his resources.

Rhizomania caused by the Beet necrotic yellow vein virus (BNYVV) is a worldwide problem that can lead to loss of tonnage and lower percent sucrose in the field. BNYVV can also reduce the storability of roots. To identify germplasm with resistance to these problems, 18 sugarbeet germplasm lines developed by the USDA-ARS Ft. Collins sugarbeet program and four check cultivars were screened in a field experiment arranged in a randomized complete block design with 6 replications. During the growing season plants were evaluated for foliar rhizomania symptoms. At harvest on 4 October 2012, roots were evaluated for rhizomania symptoms and then placed into an indoor commercial sugarbeet storage building in Paul, ID. Foliar symptoms ranged from 0% for resistant...

Assessment of Phosphorus Retention in   Irrigation Laterals
Provedor de dados: 18
Autores: Ippolito, J.A.; Nelson, N.O.
Irrigation  laterals  transport  irrigation  return  flow,  including  water,  sediment, and dissolved nutrients, such as phosphorus (P), back to surface water bodies. Phosphorus transformations during transport can affect both P bioavailability and the best management practices selected to minimize P inputs to waters of the United States. The objective of this study  was  to  determine  P  retention  in  three  irrigation  laterals.  Soluble  reactive  P  (SRP) concentrations in lateral waters were increased from 0.08 to 0.25 mg L -1  (0.08 to 0.25 ppm) by constantly injecting a phosphate (PO4) solution for 2.5 hours.

Transport of steroid hormones in the vadose zone after land application of beef cattle manure
Provedor de dados: 18
Autores: Van Donk, S.J.; Bigas, S; Kranz, W.L.; Snow, D.D.; Bartlelt-Hunt, S.L.; Mader, T.L.; Shapiro, C.A.; Shelton, D.P.; Tarkalson, D.D.; Zhang, T.C.; Ensley, S.M.
A variety of naturally occurring steroid hormones are regularly excreted by livestock, while additional steroid hormones have been used as growth promoters by the livestock industry. Depending on manure age and storage conditions, both groups of compounds are likely to be present during application to crops. Recent research suggests that some estrogens, androgens and progestagens in surface waters may originate from runoff after land application of livestock manure. Groundwater may also be impacted by livestock manure when used as a nutrient source to crops and may be indicated by excess nitrate in water. Few studies have been conducted to investigate the potential of steroid hormones contamination of groundwater. The objective of this study was to monitor...

Riparian Shrub Metal Concentrations and Growth in Amended Fluvial Mine Tailings
Provedor de dados: 18
Autores: Meiman, P.; Davis, N.R.; Brummer, J.; Ippolito, J.A.
Fluvial mine tailing deposition has caused extensive riparian damage throughout the western United States.  Willows are often used for fluvial mine tailing revegetation, but some species accumulate excessive metal concentrations which could be detrimental to browsers.  In a greenhouse experiment, growth and metal accumulation of Geyer willow, Drummond’s willow, diamondleaf willow, Bebb willow, thinleaf alder, water birch, red-osier dogwood, and shrubby cinquefoil were evaluated for potential revegetation use.  Bare-root shrubs were grown in tailings collected from three acidic, metal-contaminated (i.e. cadmium, copper, lead, and zinc) fluvial deposits near Leadville, Colorado, USA.  Tailings were amended with only lime to raise the soil pH to 7, or with...

Oilseed Radish Effects on Soil Structure and Soil Water Relations
Provedor de dados: 18
Autores: Lehrsch, G.A.; Gallian, J.J.
Oilseed radish (Raphanus sativus spp. oleifera) reduces sugarbeet cyst nematode (Heterodera schachtii) populations. Fall-incorporated radish biomass may also increase the yield and quality of subsequently grown sugarbeet (Beta vulgaris L.) by improving soil physical and hydraulic properties. This field study determined radish effects on nearsurface soil aggregate stability, water-stable aggregate size distribution, bulk density, and field-saturated water content, as well as infiltration and hydraulic conductivity measured at water supply potentials of ‑40, ‑20, and +0 mm H2O. In 2003 and 2004 in Twin Falls, ID, radish were grown in a Portneuf silt loam (Durinodic Xeric Haplocalcid) for about 10 weeks in the fall, then incorporated later that fall by...

Rejection criteria for open-path Fourier transform infrared spectrometry during continuous atmospheric monitoring
Provedor de dados: 18
Autores: Shao, L.; Pollard, M.J.; Griffiths, P.R.; Westermann, D.T.; Bjorneberg, D.L.
Over 32,000 interferograms measured during open-path Fourier transform infrared (OP/FT-IR) measurements at dairy and hog farms were  evaluated for anomalies. Five types of anomalies could be distinguished: a reduction in the interferogram intensity because of weather-related  optical misalignment; an increase in the amplitude of interferograms measured with too short a path-length that leads to a non-linear detector  response; a periodic interference caused by wind-induced vibrations; the presence of spikes in the interferogram; and an increase in the noise level  of the interferogram (and hence of the spectrum) because of the effect of electrical interference. Prior to testing for the presence of anomalous data,  each interferogram is subjected to a...

Emissions of Ammonia, Methane, Carbon Dioxide and Nitrous Oxide From Dairy Cattle Housing and Manure Management Systems
Provedor de dados: 18
Autores: Leytem, A.B.; Dungan, R.S.; Bjorneberg, D.L.; Koehn, A.C.
Concentrated animal feeding operations emit trace gases such as ammonia (NH3), methane (CH4), carbon dioxide (CO2), and nitrous oxide (N2O) to the atmosphere. The implementation of air quality regulations in livestock-producing states increases the need for accurate on-farm determination of emission rates. The objective of this study was to determine the emission rates of NH3, CH4, CO2, and N2O from three source areas (open-lots, lagoon, compost) on a commercial dairy located in southern Idaho. Average emissions per cow per day from the open-lots were 0.12 kg NH3, 0.49 kg CH4, 26.9 kg CO2, and 0.01 kg N2O. Average emissions from the lagoon (g per m square per day) were 1.5 g NH3, 132 g CH4, 391 g CO2, and 0.36 g N2O. Average emissions from the compost...

Effects of tillage system and nitrogen supply on sugarbeet production
Provedor de dados: 18
Autores: Tarkalson, D.D.; Bjorneberg, D.L.; Moore, Amber.
The sugarbeet (Beta vulgaris L.) industry in Idaho is interested in strip tillage (ST) primarily due to the potential savings in tillage costs. This study was conducted to evaluate the use of strip tillage in Idaho compared to conventional tillage practices and to evaluate N requirements of sugarbeet under ST and conventional tillage.  The effect of tillage method (strip tillage, moldboard plow system [MP], and chisel plow system [CP]) and N supply (5 levels) on sugarbeet production factors were investigated in Kimberly, ID from 2008 to 2010 on a Portneuf silt loam with barley as the previous crop. Root and estimated recoverable sucrose (ERS) yields were the same under all three tillage practices.  However, estimated tillage costs for ST were from 53...

Autores: Lentz, R.D.; Ippolito, J.A.
When added to soils, carbon-rich biochar derived from the pyrolysis of woody materials can sequester atmospheric carbon dioxide, mitigate climate change, and potentially increase crop productivity.  However, research is needed to confirm the suitability and sustainability of biochar application to different soils.  We applied four treatments (dry wt.) to an irrigated calcareous soil in Nov. 2008: control; stockpiled dairy manure, 18.8 Mg/ha; hardwood-derived biochar, 22.4 Mg/ha; and manure + biochar using previous rates.  Nitrogen fertilizer was applied when needed (based on pre-season soil test N and crop requirements) in all plots and years with N mineralized from added manure included in this determination.  Available soil nutrients (NH4-N, NO3-N, Olsen...

Interaction of calcium and phytate in broiler diets: 1. Effects on apparent prececal digestibility and retention of phosphorus
Provedor de dados: 18
Autores: Plumstead, P.W.; Leytem, A.B.; Maguire, R.O.; Spears, J.W.; Kwanyuen, P.; Brake, J.
Phytate P utilization from soybean meal (SBM) included in broiler diets has been shown to be poor and highly dependent on dietary Ca intake. However, the effect of Ca on P utilization and on the optimal ratio of Ca to nonphytate P (Ca:NPP) when diets contained varying levels of phytate has not been clearly shown and was the objective of this research. A factorial treatment structure was used with 4 dietary Ca levels from 0.47 to 1.16% and 3 levels of phytate P (0.28, 0.24, and 0.10%). Varying dietary phytate P levels were obtained by utilizing SBM produced from 3 varieties of soybeans with different phytate P concentrations.

Phosphorus losses from an irrigated watershed in the Northwestern U.S.: Case study of the Upper Snake Rock Watershed
Provedor de dados: 18
Autores: Bjorneberg, D.L.; Leytem, A.B.; Ippolito, J.A.; Koehn, A.C.
Watersheds utilizing surface water for irrigation often return a portion of the water to a water body. This irrigation return flow often includes sediment and nutrients that reduce the quality of the receiving water body. Research in the 82,000 ha Upper Snake Rock (USR) watershed from 2005 to 2008 showed that, on average, water diverted from the Snake River annually supplied 547 kg/ha of total suspended sediment (TSS), 1.1 kg/ha of total phosphorus (TP) and 0.50 kg/ha of dissolved phosphorus (DP) to the irrigation tract. Irrigation return flow from the USR watershed contributed 414 kg/ha of TSS, 0.71 kg/ha of TP and 0.32 kg/ha of DP back to the Snake River. Significantly more TP flowed into the watershed than returned to the Snake River while there was no...

Sugarbeet yield and quality when substituting compost or manure for conventional nitrogen fertilizer
Provedor de dados: 18
Autores: Lehrsch, G.A.; Brown, B.; Lentz, R.D.; Johnson-Maynard, J.L.; Leytem, A.B.
To profitably produce sugarbeet (Beta vulgaris L.) by maximizing recoverable sucrose, producers must effectively manage added nitrogen (N), whether it be from inorganic sources such as urea or from often readily available and sometimes less expensive organic sources such as manure or composted manure. Our multi-site study’s objective was to determine if equivalent sugarbeet root and sucrose yields could be achieved when substituting composted dairy cattle manure or stockpiled manure for conventional N (urea) fertilizer. Treatments at Site 1 (Parma, ID), for 2 y included a control (no N applied), urea (202 kg N/ha), compost (1089 and 2175 kg total N/ha), and manure (350 and 701 kg total N/ha).

Irrigated small-grain residue management effects on soil chemical and physical properties and nutrient cycling
Provedor de dados: 18
Autores: Tarkalson, D.D.; Brown, B.; Kok, H.; Bjorneberg, D.L.
The effects of straw removal from irrigated wheat and barley fields cropped to wheat and barley on soil properties and nutrient cycling is a concern due to its potential impact on the sustainability of agricultural production.  Increasing demand of straw for animal bedding and the potential development of cellulosic ethanol production will likely increase the demand in the future.  Previous reviews addressing changes in soil properties when crop residues are removed focused primarily on rain-fed systems. This paper reviews published research assessing the effects of wheat and barley straw removal on soil organic carbon (SOC), and analyzes changes in nutrient cycling within irrigated wheat and barley production systems.  The effects of straw removal on bulk...

Leuconostoc spp. associated with root rot in sugar beet and their interaction with rhizoctonia solani
Provedor de dados: 18
Autores: Strausbaugh, C.A.
Rhizoctonia root and crown is an important disease problem in sugar beet caused by Rhizoctonia solani and also shown to be associated with Leuconostoc.  Since, the initial Leuconostoc studies were conducted with only a few isolates and the relationship of Leuconostoc with R. solani is poorly understood, a more thorough investigation was conducted.  A total of 203 Leuconostoc isolates were collected from recently harvested sugar beet roots in southern Idaho and southeastern Oregon during 2010 and 2012: 88 and 85% L. mesenteroides, 6 and 15%  L. pseudomesenteroides, 2 and 0% L. kimchi, and 4 and 0% unrecognized Leuconostoc sp., respectively.  Based on 16S rRNA sequencing, haplotype 11 (L. mesenteroides isolates) comprised 68 to 70% of the isolates both...

Manure and fertilizer effects on carbon balance and losses for irrigated corn
Provedor de dados: 18
Autores: Lentz, R.D.; Lehrsch, G.A.
Little is known about inorganic fertilizer or manure effects on organic carbon (OC) and inorganic C (IC) losses from a furrow irrigated field, particularly in the context of other system C gains or losses.  In 2003 and 2004, we measured dissolved organic and inorganic C (DOC, DIC), particulate OC and IC (POC, PIC) concentrations in irrigation inflow, runoff, and percolation waters (6-7 irrigations/y); C inputs from soil amendments and crop biomass; harvested C; and gaseous C emissions from field plots cropped to silage corn (Zea mays L.) in southern Idaho.  Annual treatments included:  (M) 13 (y 1) and 34 Mg/ha (y 2) stockpiled dairy manure; (F) 78 (yr 1) and 195 kg N/ha (y 2) inorganic N fertilizer; or (NA) no amendment--control.

Phytate utilization and phosphorus excretion by broiler chickens fed diets containing cereal grains varying in phytate and phytase content
Provedor de dados: 18
Autores: Leytem, A.B.; Willing, B.P.; Thacker, P.A.
Eighty, 12-day-old, male broiler chicks, were fed one of four diets to determine the effects of  feeding grains varying in phytate phosphorus (P) and intrinsic phytase activity on ileal and excreta  P digestibility and composition. The diets contained approximately 970.7 g grain kg?1 (maize, high  fat–low lignin oat, normal barley or low-phytate barley) with the cereal supplying the sole source of  dietary P. The diets were fed for a 7-day acclimation period followed by a 2 day excreta collection  while ileal digesta was collected at slaughter on day 21. The coefficients of ileal apparent digestibility  (CIAD) for P and phytate P ranged from 0.79 (normal barley) to 0.86 (maize and low-phytate barley)  and 0.76 (low-phytate barley) to 0.89 (maize),...

The global feed market: Asian perspectives
Provedor de dados: 31
Autores: Zhou,   Zhang-Yue.
Global demand for feed, especially cereal feed, is expected to increase in the decades to come. At the global level, demand for cereal feed will be met by the supply. There are, however, disparities between regions. As a result of strong livestock industry development, the Asian region as a whole will have a shortage of cereal feed and will become a major cereal feed importer. This paper examines existing projections of feed demand and supply in the Asian region. It also sheds light on the implications of the feed demand and the livestock industry development in the Asian region for the Australian rural industries.

Autores: Di Pasquale,   Jorgelina; Adinolfi,   Felice; Capitanio,   Fabian.
The objective of this study is to analyze consumer behaviour in relation to functional foods by a direct survey. To this end, the proposal is an analysis of the reasons for choosing to consume this type of food or not, accompanied by a supplementary investigation, mostly to assess the relationship between consumption patterns and willingness to pay (WTP) for the most common categories of functional foods, such as milk fortified with CLA (conjugated linoleic acid). Our research shows that a proportion of the population is unaware of the existence of functional foods and their properties. Moreover, it shows that when the concept of functional foods is explained to consumers, this creates a greater willingness to pay for such food, which is strongly linked to...

Bringing competition to urban water supply
Provedor de dados: 31
Autores: Sibly,   Hugh; Tooth,   Richard.
This paper proposes a market-based reform that would introduce competition into the provision of urban water. This proposal calls for a decoupling of infrastructure control and ownership of water whereby the property rights to water would be transferred to private hands. The proposal involves periodically allocation (e.g. by auction) of existing water stock held in urban catchments to virtual suppliers who then compete in providing bulk water. This change when coupled with effective third party access and retail competition would lead to a competitive market for the provision of urban water. The approach aims to address concerns over inefficient pricing and infrastructure provision under the current arrangement.

Raising the Financial Costs of Children and Fertility Responses: Evidence from the Kibbutz
Provedor de dados: 31
Autores: Ebenstein,   Avraham; Hazan,   Moshe; Simhon,   Avi.
Prior to 1996, Israelis in collective communities (kibbutzim) shared the costs of raising children equally. This paper examines the impact of the privatization of kibbutzim on fertility behavior among members. We find that fertility declined by 6-15 percent following the shift to privatization. In light of the massive change in financial costs associated with childbearing due to privatization, our results suggest that financial considerations may be a more modest factor in fertility decisions than generally regarded.

This paper investigates the rationale for local and sustainable food systems and retailer co-operatives as their entry points within local conditions. Emphasis is on localised food networks and connection between socially as well as environmentally sustainable production, distribution and consumption. Investigated is the premise that co-operative organisational structures, for reasons of their long-term socially responsible origins are at the forefront of development of local and sustainable food systems and are thereby in a position to offer a specific contribution to market development. Two key research questions are proposed: Firstly, is there a pre-determination of co-operatives to issues of sustainable and local food sourcing given the historical and...

Modeling of the cure fraction in survival studies
Provedor de dados: 31
Autores: Lambert,   Paul C.
Cure models are a special type of survival analysis model where it is assumed that there are a proportion of subjects who will never experience the event and thus the survival curve will eventually reach a plateau. In population-based cancer studies, cure is said to occur when the mortality (hazard) rate in the diseased group of individuals returns to the same level as that expected in the general population. The cure fraction is of interest to patients and a useful measure to monitor trends and differences in survival of curable disease. I will describe the strsmix and strsnmix commands, which t the two main types of cure fraction model, namely, the mixture and nonmixture cure fraction models. These models allow incorporation of the expected background...

Autores: Greene,   Catherine R.; Slattery,   Edward; McBride,   William D.
Organic agriculture has established a foothold in many U.S. farm sectors, particularly among horticultural specialties, but the overall use of organic practices lags behind that of many other countries. Recent data from several producer surveys illustrate notable differences and similarities between organic and conventional farmers. Emerging issues in the organic sector include dampened consumer demand resulting from the weaker U.S. economy and potential competition from new labels like the “locally grown” label.

Relationship Quality and Innovation Capacity of Chains: The Case of the Traditional Food Sector in the EU
Provedor de dados: 31
Autores: Gellynck,   Xavier; Kuhne,   Bianka; Weaver,   Robert D.
The purpose of the paper is to explore how the perceived relationship quality is related to the innovation capacity in chains of the traditional food sector. Based on suggestions from theory and previous studies, empirical evidence is drawn from a survey of 90 traditional food chains including 270 chain partners from three European countries in four traditional food product categories. Heterogeneity across these chains is first examined based on cluster analysis that identifies three distinct clusters interpreted as reflecting three levels of intensity in innovation capacity: high, medium, and low. Next, we define measures of the chain relationship quality through characteristics such as trust, conflict and reputation. Results suggest that various aspects...

The Complexities of the Interface between Agricultural Policy and Trade
Provedor de dados: 31
Autores: Schmitz,   Troy G.; Schmitz,   Andrew.
Tariff and non-tariff barriers are widespread as applied to agricultural trade. The theory of gains from trade considers the impacts of free trade relative to no trade and to non-tariff barriers, while the theory of agricultural policy generally places little weight on the international trading sector. However, it is necessary to combine agricultural policy with the international trading sector so that agricultural policy instruments such as price supports are considered together with barriers to trade such as tariffs. This is possible within the context of welfare economics when considering the costs and benefits of alternative agricultural and trade policies.

Customer relationships strategy: an Australian cattle producers’ case study

Autores: Jie,   Ferry.
An analysis of beef supply chains revealed that a strategic focus on beef quality was critical to that part of the chain involving producers. Moreover, beef quality was directly related to customer relationship management. Across the industry, there are a diverse set of customers each with different needs. This means that it is difficult for individual producers to develop a successful approach to customer relationship management without developing a product focus on one or two of these customer segments.

Economic Potential of Swine Effluent in Intensified Forage Systems in the Southern Plains
Provedor de dados: 31
Autores: Park,   Seong Cheol; Vitale,   Jeffrey D.; Turner,   Jason Clemn; Stoecker,   Arthur L.; Hattey,   Jeffory A.
The projected long-run increase in corn prices from $2.50 to $3.50 per bushel is expected to have a similar effect on feed prices, pushing up feed costs by as much as 50 percent. With feed costs on the rise, increasing forage production through more intensive management techniques becomes a potentially viable option. This study uses experimental data from a seven-year study in the Oklahoma Panhandle to assess the economic feasibility of intensifying forage production. Four commonly used forage grasses in the region were field tested using two alternative fertilizer sources – swine effluent and urea. The results found that only the two cool season grasses – orchard grass and wheatgrass – generated positive economic returns under intensification.

Profile likelihood for estimation and confidence intervals
Provedor de dados: 31
Autores: Royston,   Patrick.
Normal-based confidence intervals for a parameter of interest are inaccurate when the sampling distribution of the estimate is nonnormal. The technique known as profile likelihood can produce confidence intervals with better coverage. It may be used when the model includes only the variable of interest or several other variables in addition. Profile-likelihood confidence intervals are particularly useful in nonlinear models. The command pllf computes and plots the maximum likelihood estimate and profile likelihood–based confidence interval for one parameter in a wide variety of regression models.

The discipline boomed in the 1960s and 70s, both internationally and at UNE. Yet it has fallen into relative decline subsequently. He suggests some of the reasons for the decline, focussing particularly on issues in Australia. He discusses the need for a revival in a world in which food security is likely to be an increasingly serious problem. He concludes with thoughts about...

Are Competitors' Free Trade Agreements Putting U.S. Agricultural Exporters at a Disadvantage?
Provedor de dados: 31
Autores: Wainio,   John; Dyck,   John H.; Gehlhar,   Mark J.; Vollrath,   Thomas L.
The growing number of free trade agreements among U.S. competitors has prompted questions about whether U.S. agricultural exporters may lose a share of the global market. ERS research shows that the recently created ASEAN-China and ASEANAustralia/ New Zealand free trade agreements are likely to have modest adverse impacts on U.S. agricultural exports. The Mercosur-Colombia free trade agreement has reduced U.S. agricultural exports to Colombia; U.S. grain sellers face increasingly stiff competition due to preferential tariffs granted to Mercosur exporters.

A magyarországi máktermelésről
Provedor de dados: 31
Autores: Karacsony,   Peter; Toth,   Kalman; Pinek,   Gyula; Pal,   Robert.
Hazánkban az utóbbi években egyre nagyobb területeken folyik alkaloida és étkezési mák termelése. Megállapítható, hogy nem igazolódtak be azok a várakozások, melyek az uniós csatlakozástól a máktermelés csökkenését várták, annak ellenére, hogy az unió korlátozta egyes hazai, magasabb alkaloidatartalmú fajták termelését. Vizsgálataink alapján megállapítható, hogy a máktermelés magas hektáronkénti termelési költsége ellenére jövedelmező. Ha a hazai máktermelést az 1960-as évek szintjére emelnék, akkor az hozzájárulhatna a napjainkban fennmaradásukért és mindennapi megélhetésükért küzdő – elsősorban a szegényebb kelet-magyarországi régiókban – gazdálkodók megélhetéséhez.   ------------------------------------- The area used for growing poppy seed for human...

Changing business environment: implications for farming
Provedor de dados: 31
Autores: Malcolm,   Bill.
The natural, technological, economic, political and social environment in which farmers farm constantly changes. History has lessons about change in agriculture and about farmers coping with change, though the future is unknowable and thus always surprising. The implication for farm operation is to prepare, do not predict.

Robust standard errors for panel regressions with cross–sectional dependence
Provedor de dados: 31
Autores: Hoechle,   Daniel.
I present a new Stata program, xtscc, that estimates pooled ordinary least-squares/weighted least-squares regression and fixed-effects (within) regression models with Driscoll and Kraay (Review of Economics and Statistics 80: 549–560) standard errors. By running Monte Carlo simulations, I compare the finite-sample properties of the cross-sectional dependence–consistent Driscoll–Kraay estimator with the properties of other, more commonly used covariance matrix estimators that do not account for cross-sectional dependence. The results indicate that Driscoll–Kraay standard errors are well calibrated when cross-sectional dependence is present. However, erroneously ignoring cross-sectional correlation in the estimation of panel models can lead to severely...

Savings and technology choice for risk averse farmers
Provedor de dados: 31
Autores: Brennan,   Donna C.
Farmers in developing countries have limited opportunities for borrowing to even out variability associated with risky farm income, but they can save. A dynamic programming model of savings is presented in the current paper which examines optimal savings strategies for farmers, using a case study of integrated rice-shrimp farms in Vietnam. It is shown that when savings are accounted for, the expected utility ranking of different risky farm choices may not differ that much between farmers with different levels of risk aversion.

Marketing Efficiency of Green Peas under Different Supply Chains in Punjab
Provedor de dados: 31
Autores: Sidhu,   R.S.; Sidhu,   M.S.; Singh,   J.M.
During the year 2007-08, the area under green peas in Punjab was 18.45 thousand hectares with a production of 1.11 lakh tonnes. The total consumption at the farm level being just 2.54 per cent, the marketed surplus was 97.46 per cent. The maximum quantity of green peas was sold by the growers in the wholesale market (about 89%) and the rest was sold at the farm, in the village and in Apni Mandi. The marketing of green peas has been studied by three supply chains, viz. I: Producer → wholesaler (through commission agent) → retailer → consumer; II: Producer → retailer (through commission agent) → consumer; III: Producer → consumer. The net price received by the producer was 67 per cent, 69 per cent and 94 per cent in supply chains I, II and III respectively...

Does Agriculture Help Poverty and Inequality Reduction? Evidence from Vietnam
Provedor de dados: 31
Autores: Viet Cuong,   Nguyen.
This paper measures impacts of production of crops, forestry, livestock and aquaculture on household welfare, poverty and inequality in rural Vietnam using fixed-effects regressions. Data used in this paper are from Vietnam Household Living Standard Surveys 2002 and 2004. It is found that impact estimates of the production of crops and forestry on per capita income and consumption expenditure are not statistically significant. Impact estimates of the livestock production are positive and statistically significant for per capita income, but not statistically significant for per capita expenditure. However, the aquacultural production has positive and statistically significant impacts on both income and expenditure. As a result, the aquacultural production...

Autores: Alford,   Andrew R.; Clark,   Richard A.; Griffith,   Garry R.
A critical component of the Continuous Improvement and Innovation (CI&amp;I) process described in Paper 4 above is Performance Assessment - analysing and interpreting the results achieved, and not achieved, in relation to the focus and target outcomes. This is made easier if specific Key Performance Indicators (KPIs) are established during Action Design and monitored during Action Implementation. The target outcome for the Measurement, Monitoring and Evaluation (MME) Strategy is to design and implement effective and efficient MME mechanisms that will demonstrate improvements and innovations in individual beef businesses and supply chains and in the broader Australian beef industry.

This study used information about a farm in the Victorian Mallee during the period 1998 – 2005 to analyse the profitability of investing in Precision Agriculture and Site-Specific Crop Management technology and farming systems. Two equipment guidance systems were evaluated. Both guidance systems earned more than 8 percent real return p.a. on the extra capital invested. A Real-Time Kinetic (RTK) guidance system with a precision of 2 cm and a capital cost of $50,000 was less profitable than a Sub-Metre guidance system with 20 cm accuracy and costing $20,000. Producers investing in RTK guidance technology would be well-paid to also adopt supporting management practices that enhance crop gross margins or provide other benefits. The capital cost of GPS...

Reconsiderando la metodología FAO sobre el cálculo del número de personas que pasan hambre en el mundo
Provedor de dados: 31
Autores: Morales-Opazo,   Cristian; Barreiro-Hurlé,   Jesús.
FAO measure of undernourishment is calculated based on three main parameters: dietary energy supply (DES), minimum dietary energy requirement (MDER), and the coefficient of variation of dietary energy consumption (CV). In the current implementation of this methodology, the DES and the MDER change over time, as would be expected. The CV, however, remains constant. However, we expect the CV to change over time and be a function of income and prices. This paper discusses why the CV should change in response to changes in these variables, and suggests a practical way to estimate changes in the CV over time in the absence of survey data.

Australasian environmental economics: contributions, conflicts and ‘cop-outs’
Provedor de dados: 31
Autores: Bennett,   Jeffrey W.
Australian and New Zealand environmental economists have played a significant role in the development of concepts and their application across three fields within their subdiscipline: non-market valuation, institutional economics and bioeconomic modelling. These contributions have been spurred on by debates within and outside the discipline. Much of the controversy has centred on the validity of valuations generated through the application of stated preference methods such as contingent valuation. Suggestions to overcome some shortcomings in the work of environmental economists include the commissioning of a sequence of non-market valuation studies to fill existing gaps to improve the potential for benefit transfer.

Speaking Stata: Spineplots and their kin
Provedor de dados: 31
Autores: Cox,   Nicholas J.
The term spineplot has been applied over the last decade or so to a type of bar chart used particularly for showing frequencies, proportions, or percentages of two cross-classified categorical variables. The principle is that the areas of rectangular tiles are proportional to the frequencies in the cells of a contingency table. Often both coarse and fine structure are easy to see, including departures from independence. The main idea has, in fact, been rediscovered repeatedly over at least the last 130 years. In its most general form, it has been widely publicized under the name mosaic plots. This column introduces, discusses, and exemplifies a Stata implementation of spineplots. It is noted that a restriction to two variables is more apparent than real,...

Public investment in agricultural research and development in Australia remains a sensible policy option
Provedor de dados: 31
Autores: Mullen,   John D.
There is evidence that productivity in Australia’s broadacre agriculture (extensive cropping and livestock industries) has been slowing in the past decade. A series of poor seasons has been partly responsible, but an econometric analysis of structural changes in the trend of total factor productivity (TFP) indicates that stagnant public investment in agricultural R&amp;D has also made a significant contribution to this slowdown in TFP. Related econometric analysis of the returns to public investment in agricultural R&amp;D in the broadacre sector confirms that the rate of return to investment remains high. Despite these findings, a recent enquiry by Australia’s Productivity Commission into the financing of rural research suggests that the public sector may...

Both are general estimators designed for situations with “small T, large N” panels, meaning few time periods and many individuals; independent variables that are not strictly exogenous, meaning they are correlated with past and possibly current realizations of the error; fixed effects; and heteroskedasticity and autocorrelation within individuals.

A general-purpose method for two-group randomization tests
Provedor de dados: 31
Autores: Kaiser,   Johannes; Lacy,   Michael G.
We outline a novel approach to calculate exact p-levels for two-sample randomization tests. The approach closely resembles permute in its applications, with the main difference being that the results are approximated only if the execution time needed to calculate exact p-levels would exceed a specified maximum. We demonstrate its use by deriving p-levels for the significance of Somers’ D, the coefficient of variation, the difference in means and in medians, and the difference in two multinomials.

Beyond semi-dwarf wheat yield increases: impacts on the Australian wheat industry of on-going spillovers from the International Maize and Wheat Improvement Center
Provedor de dados: 31
Autores: Brennan,   John P.
Wheat genetic materials developed from research at the International Maize and Wheat Improvement Center (CIMMYT) in Mexico for developing countries have provided spillover benefits to Australia. Varieties developed from those genetic materials have resulted in yield increases in Australia. While the initial impact came through the introduction of higher-yielding semi-dwarf wheat crops, those impacts have continued in the post-semidwarf period. CIMMYT’s success in developing countries has also reduced the world price for wheat. While the lower prices affect returns in Australia, the increased yields in Australia from the CIMMYT spillovers from both the semi-dwarfs and the postsemidwarf phases have provided benefits to Australia averaging A $30 million per...

However, this presupposes that differences in sustainability are communicated to consumers. Even if food products are eco-labelled and consumers are motivated to support sustainability, a number of potential barriers may prevent consumers from using the information to make sustainable choices. Six such barriers are discussed in this paper.

Practical fixed-effects estimation methods for the three-way error-components model
Provedor de dados: 31
Autores: Andrews,   Martyn; Schank,   Thorsten; Upward,   Richard.
Methods for fixed-effects estimation of the three-way error-components model are not yet standard. Where possible, we make the fixed-effects methods originally developed by Abowd, Kramarz, and Margolis (Econometrica 67: 251–333) for linked worker-firm data more accessible. We also show how these methods can be implemented in Stata. There is a caveat, however. If the researcher wants to recover estimates of the error components themselves, and the number of units at the higher level of aggregation is large, memory or matrix constraints may make using Stata to estimate the components themselves infeasible.

Autores: Cox,   Nicholas J.
Spells in time series (and more generally in any kind of one-dimensional series) may be defined as sequences of observations that are homogeneous in some sense. For example, a categorical variable may remain in the same state, or values of a measured variable may satisfy the same true–false condition. Devices for working with spells in Stata include marking the start of each spell with indicator variables and tagging spells with integer codes. Panel data are easy to handle with the by: prefix. Some kinds of spell identification require two passes through the data, as when only spells of some minimum length are of interest or short gaps are tolerable within spells. Many questions concerning spells are easy to answer given careful use of by: and appropriate...

Multinomial goodness–of–fit: Large–sample tests with survey design correction and exact tests for small samples
Provedor de dados: 31
Autores: Jann,   Ben.
I introduce the new mgof command to compute distributional tests for discrete (categorical, multinomial) variables. The command supports largesample tests for complex survey designs and exact tests for small samples as well as classic large-sample x2-approximation tests based on Pearson’s X2, the likelihood ratio, or any other statistic from the power-divergence family (Cressie and Read, 1984, Journal of the Royal Statistical Society, Series B (Methodological) 46: 440–464). The complex survey correction is based on the approach by Rao and Scott (1981, Journal of the American Statistical Association 76: 221–230) and parallels the survey design correction used for independence tests in svy: tabulate. mgof computes the exact tests by using Monte Carlo methods...

Stakeholder Analysis of Agroparks
Provedor de dados: 31
Autores: Wubben,   Emiel F.M.; Isakhanyan,   Gohar.
An agropark is a cluster in which several primary producers and processors cooperate to enhance sustainable agro-food production. Because agroparks represent complex system innovations, this article studies their realisation trajectories from the stakeholder management perspective. By using the case study method, the research confirms that agroparks are system innovations involving many participants, most of them being key stakeholders. The different stakes and power positions, and their impact have been assessed. and managed in line with the realisation process of the agropark. The paper provides first learnings on stakeholder management in agropark projects, which may promote their realisation.

The practices products and resource management of Australia’s farm managers and their environmental consequences are being closely scrutinised by the community. Accreditation is an approach increasingly being used to monitor these matters across agricultural industries. Quality Assurance and Environmental Management Systems have gained prevalence as a means of validating activity and providing evidence of meeting stewardship responsibilities. This paper reviews the range of programs and systems available to primary producers across Australia. In this review it is argued that the growth of these accreditation systems has given rise to confusion, duplication, and increased management and industry costs, with limited assurances to customers and the community...

Evaluation of Malaysia’s Food Balance of Trade Plan: Achievement Rates
Provedor de dados: 31
Autores: Mohamed Arshad,   Fatimah; Mohd. Noh,   Kusairi.
Malaysia has always been a net food importer in the last four decades. In 2007, the deficit in the food trade stood at RM9.7 billion (or USD2.9 billion). In 2002, Malaysia implemented a policy towards achieving a surplus balance of trade in food of RM1.2 billion (or USD352 billion) by 2010. This paper evaluates the policy in terms of the achievement rates of the plan. The analysis suggests that the actual trade data shows the intended targets are likely not to be met; in fact the deficit is expected to grow bigger with time. While the objective was commendable, the targets, rationales and strategies for such a plan require a serious rethinking

Autores: Benda,   Petr; Havlicek,   Zdenek; Lohr,   Vaclav; Havranek,   M.
As a result of technological progress ICT (Information and Communication Technologies) has created the so-called „digital divide“. Some people are unable to individually respond to this progress, but the proper use of ICT can help them overcome this handicap. One of the possibilities is to create accessible and usable applications depending on the character and level of disability. In accordance with the European CertiAgri project, e-learning tools are used for integrating people with disabilities into the horticultural area. The paper specifically describes examples of simple teaching aids from the practical „green care“ course, which focus on the skills of people with mental disabilities.

Do USDA Announcements Affect Comovements Across Commodity Futures Returns?
Provedor de dados: 31
Autores: Karali,   Berna.
The value of USDA reports has long been a question of interest for researchers and practitioners. However, the impact of announcements on comovements across related commodity prices has not been explored beyond financial asset markets. This is important because the structure of the relationship between commodities could change depending on the type of information revealed in the announcement, thus affecting price perceptions, hedging ratios, and portfolio return variance. This study simultaneously measures the impact of selected USDA reports on the conditional variances and covariances of returns on corn, lean hogs, soybeans, soybean meal, and soybean oil futures contracts using a multivariate GARCH model. It is shown that the largest movements in...

Stata’s main data model treats observations in rows and variables in columns quite differently, but rowwise problems also arise that require working against the grain. This column shows how to exploit existing functions and egen functions when they exist and apply to such problems. It offers advice on how to build your own loops, egen functions, or programs when needed. Mata provides especially convenient tools for constructing many such functions and programs, centered on putting selected data into matrices and then processing each observation as a separate vector. Two programs, rowsort and rowranks, are formally published with this column.

Implementing double-robust estimators of causal effects
Provedor de dados: 31
Autores: Emsley,   Richard; Lunt,   Mark; Pickles,   Andrew; Dunn,   Graham.
This article describes the implementation of a double-robust estimator for pretest–posttest studies (Lunceford and Davidian, 2004, Statistics in Medicine 23: 2937–2960) and presents a new Stata command (dr) that carries out the procedure. A double-robust estimator gives the analyst two opportunities for obtaining unbiased inference when adjusting for selection effects such as confounding by allowing for different forms of model misspecification; a double-robust estimator also can offer increased efficiency when all the models are correctly specified. We demonstrate the results with a Monte Carlo simulation study, and we show how to implement the double-robust estimator on a single simulated dataset, both manually and by using the dr command.

The Stata command felsdvreg to fit a linear model with two high–dimensional fixed effects
Provedor de dados: 31
Autores: Cornelissen,   Thomas.
This article proposes a memory-saving decomposition of the design matrix to facilitate the estimation of a linear model with two high-dimensional fixed effects. A common way to fit such a model is to take into account one of the effects by including dummy variables and to sweep out the other effect by the within transformation (fixed-effects transformation). If the number of panel units is high, creating and storing the dummy variables can involve prohibitively large computer-memory requirements. The memory-saving procedure to set up the moment matrices for estimation presented in this article can reduce the memory requirements considerably. The companion Stata ado-file felsdvreg implements the estimation method, takes care of identification issues, and...

Bargaining rationale for cooperative generic advertising
Provedor de dados: 31
Autores: Crespi,   John M.; James,   Jennifer S.
The beggar-thy-neighbour aspect of commodity advertising means that benefits to one commodity from advertising come at the expense of other commodities. The effect can be mitigated by cooperation among groups as shown by Alston, Freebairn and James (AFJ). A drawback to AFJ’s analysis is that some cooperative outcomes require side payments from one producer group to another. This paper offers a bargaining solution as an alternative to cooperation in the case where cooperative side payments would be needed. We show that while bargaining without side payments is not as effective as cooperation at reducing beggar-thy-neighbour effects, it is a welfare improving alternative to non-cooperation and is likely more practical in many situations.

Many value-added practices cannot be observed by feeder cattle buyers. Third-party verification can decrease market inefficiency associated with this asymmetric information. We evaluate the effectiveness of a verification program, the Oklahoma Quality Beef Network, in increasing received prices. We estimate the value of verification, weaning, vaccinating, certification and phenotypic traits of feeder cattle at Oklahoma auctions. Results indicate that the OQBN program adds $2.39 to $5.74/cwt. Vaccinating calves adds $1.44/cwt, and weaning calves adds $2.05/cwt. Differential values for lot size, average weight, hide color, frame size, conditioning, Brahman influence, gender and other characteristics are also reported.

The efficiency of the Chinese wheat and soybean futures markets is studied. Formal statistical tests were conducted based on Johansen’s cointegration approach for three different cashmarkets and six different futures forecasting horizons ranging from1 week to 4 months.The results suggest a long-termequilibrium relationship between the futures price and cash price for soybeans and weak short-term efficiency in the soybean futures market. The futures market for wheat is inefficient, which may be caused by overspeculation and government intervention.

This paper examines wine grape supply contracts used in the main grape growing regions of Australia. An empirical analysis provides insight into specific aspects of contract design and implementation. Statistical analyses of sample data reveal differences between regions in contract specifications. Lower quality grape growing regions place a greater reliance on grape quality assessment to determine bonus/penalty payments compared to higher quality regions. Contracts in higher quality regions place greater emphasis on explicit winery involvement and direction in vineyard management.Results indicate that longer duration contracts are more inclusive in terms of the number of clauses included. Evidence of risk shifting (i.e., winery to grower) for high quality...

Jowar is the main cereal crop in Maharashtra occupying 4.176 M ha area out of which rabi jowar occupied maximum area of 3.112 M ha during the year 2009-10. The gradual growth in use of technology in agriculture has resulted in increased crop productivity. The actual yields obtained are considerably lower than those recorded in the demonstration plots and research stations/farms. Therefore, there is a need to know the different yield gaps between the farmers’ fields and the demonstration plots. The study has suggested that to bridge this gap the use of recommended levels of input is most essential. The farmers should be motivated through visits to progressive farmers and organizations of field demonstrations, seminars and other communication means to use...

Vulnerability to risk among small farmers in Tajikistan: results of a 2011 survey
Provedor de dados: 31
Autores: Lerman,   Zvi; Wolfgramm,   Bettina.
Tajikistan is judged to be highly vulnerable to risk, including food insecurity risks and climate change risks. By some vulnerability measures it is the most vulnerable among all 28 countries in the World Bank’s Europe and Central Asia Region – ECA (World Bank 2009). The rural population, with its relatively high incidence of poverty, is particularly vulnerable. The Pilot Program for Climate Resilience (PPCR) in Tajikistan (2011) provided an opportunity to conduct a farm-level survey with the objective of assessing various dimensions of rural population’s vulnerability to risk and their perception of constraints to farming operations and livelihoods. The survey should be accordingly referred to as the 2011 PPCR survey. The rural population in Tajikistan is...

This study presents a method of simulating longer-term cash flows that reflect the cumulative effects of variation in seasons, prices, enterprise sequences and mixes and other management decisions. It can be used to develop full risk profiles on a whole-farm or individual-component enterprise basis for most dryland farms in southern Australia, at gross margin, profit or cash flow levels. This analysis concentrates on the cash flow implications of these various scenarios because cash flow is the indicator which includes all costs, and therefore demonstrates affordability and the long-term viability of the farm business entity. This study shows that the role of sheep in the mixed farming enterprise in south-eastern Australia is to reduce the exposure of the...

Case studies of mainstream and local food supply chains reveal the variety of ways that food products move from farms to consumers. Farms in local food supply chains maintain a diverse portfolio of products and market outlets, which may help defray large fixed costs across multiple revenue streams. Local food supply chains are more likely to provide consumers with detailed information about where and by whom products were produced.

The Brazilian production of poultry meat in 2010 reached 12.230 million tons, a growth of 11.38%, driven by increased consumption and increased exports. Mato Grosso is the 7th. Major national producer in terms of slaughter and production numbers are growing every year, considering the production of soybeans and corn and the possibility of planting new areas, making poultry the star of this new scenario. This article aims to examine contracts of broiler farms in Mato Grosso from the perspective of New Institutional Economics. The theoretical reference provides the concepts of transaction costs and governance structures. The data were derived from contracts related to the integration of poultry production in the period of 2008 and 2009, from the point of...

Measuring the Benefits to Advertising under Monopolistic Competition
Provedor de dados: 31
Autores: Boland,   Michael A.; Crespi,   John M.; Silva,   Jena; Xia,   Tian.
This paper determines the benefits and costs of firm-level advertising in a monopolistically competitive industry. The model is useful in an environment in which firm-level costs may be absent or imprecise. The empirical example uses data on the advertising for a new line of prune snacks by Sunsweet Growers between 2008 and 2010, revealing average benefit-cost estimates from $1.26 to $4.35 for every dollar allocated to the new product line.

The Impact of Settlement Design on Tropical Deforestation Rates and Resulting Land Cover Patterns
Provedor de dados: 31
Autores: Caviglia-Harris,   Jill L.; Harris,   Daniel.
Policymakers in the Brazilian Amazon face the challenge of meeting environmental and developmental goals as cities and towns within these tropical forests continue to face migration pressure. Alternative government planning strategies have been implemented to address forest clearing in conjunction with meeting social agendas. This paper uses panel estimation methods to investigate the impact of settlement design on land use. Results indicate that new settlement designs developed to further social interaction have had a negative impact on land cover and land use transformation. Thus, while new settlement designs appear to positively impact stated social goals, including greater contact between families and access to water and services, these social advances...

Towards farming-systems change from value-chain optimisation in the Australian sugar industry
Provedor de dados: 31
Autores: Antony,   George; Prestwidge,   D.; Sandell,   G.; Archer,   A.; Thorburn,   Peter; Higgins,   Andrew J.
The supply chain of the conventional Australian sugar industry is characterized by horizontal separation between the stages. Often antagonistic relations between segments, particularly farmers and millers, led to each developing their systems for their own segment’s benefit, without reference to the wider industry interests. Cane growing developed into a monoculture, reliant on material inputs and technological solutions, whose low labour intensity afforded substantial lifestyle benefits to growers. Such a system worked well while the industry was the worldwide cost leader, but it has contributed to stagnating yields and left growers exposed to the industry downturn caused by Brazilian competition. Over the past few years, CSIRO and BSES research aimed at...

Autores: Ver Ploeg,   Michele.
A small percentage of U.S. households live in “food deserts,” where access to a supermarket or large grocery store is a problem. Low-income households often leave food deserts to shop where food prices are lower. Business costs, along with characteristics of potential customers, affect where stores locate.

Supply chain management in the lamb industry: An analysis of opportunities and limitations
Provedor de dados: 31
Autores: Johnson,   Sue.
Record prices during mid-2004, tipping 530 c/kg (MLA 2004b) have lead to increased interest in the production of lamb. Overall sheep numbers have fallen by 30% in the last decade, while prime lamb production is increasing. With the consumer-dominating product selection there has been a changing role of the producer and a shift in power to retailers. In Australia the major supermarket chains – i.e. Coles, Woolworths and their subsidiaries - had 40% of the retail grocery market in 1970 (AFFA and ABARE 2000). By 2000-01 this figure had moved to 63% (ABARE 2002). Internationally Wal-Mart and Carrefour operate in more than 30 countries, with sales of 273,335 million Euro (A$488,098 million) in 2000/01. This compares with Woolworths, Coles and BiLo with sales of...

Autores: Sharma,   Gaurav; Joseph,   Joby; Tharian,   George K.; Dey,   S.K.
Among the various promotional schemes targeted for the promotion of rubber in Tripura, Block Plantation Scheme (BPS) has been introduced exclusively for the rehabilitation of scheduled tribes and scheduled castes. BPS is a comprehensive scheme with the characteristic features of group/community approach in all spheres of operations up to primary processing and marketing and family labour participation as wage labour during the immature phase of the plantations spanning six years. However, there has been a distortion in the uninterrupted supply of family labour to the scheme in the recent past due to growing popularity of employment opportunities under the Mahatma Gandhi National Rural Employment Guarantee Act, 2005 (MGNREGA) programme, which may eventually...

The political economy of quality measurement: a case study of the USA slaughter cattle market
Provedor de dados: 31
Autores: Whitley,   John E.
As agricultural products move from being economic commodities to qualitydifferentiated goods, price dispersion within specific markets increases and implicit subsidies from high quality producers to low quality producers are removed. The present paper examines how these distributional effects can influence patterns of support and opposition to changes in marketing arrangements. The simple model developed is calibrated using data from the USA slaughter cattle market. Estimates of the impact on prices of measuring quality more accurately are found to be similar in size to previous estimates of market power price suppression in the market.

A megújuló és a fosszilis energiahordozók szerepe Magyarországon

A magyar gazdaság energiaszükségletében meghatározóak a fosszilis eredetű tüzelőanyagok – kőolaj, földgáz, kőszén, illetve ezek származékai –, amelyek kimerülőben vannak, így növelik függőségünket, károsítják környezetünket. Ezért fokozott figyelmet kell fordítani az alternatív energiaforrásokra, amelyekről ma még az a véleményünk, hogy kimeríthetetlenek, kevésbé károsítják Földünket. A kutatók számára ma az jelent feladatot, hogy ezen erőforrások felhasználásának korlátait felkutassák, feltárják. Az előrelépés egyik tényezője a finanszírozásban keresendő, mert annak ellenére, hogy mintegy évtizede az aktuális kormányok folyamatosan hirdetik részarányuk növelésének szükségességét, a megfelelő – a társadalom nagy többsége számára elérhető – támogatási...

Assessment of agricultural land fund in the Czech Republic, importance and future
Provedor de dados: 31
Autores: Voltr,   Vaclav.
Assessment of land depends on the production function of soil and additional connections given by environmental requirements, by the evaluation of public goods or by the requirements for formation a fair tax policy and even by the interests of landowners. Analysis of coherences during the soil appraisal shows a relatively strong dependence on the development of year-by-year yields and cost including subsidy policy, which is strongly reflected in the grasslands. Development of subsidies does not basically influence a long- term return and costs ratio for the production on arable land. The requirements for formation of prices are given due to the need for stability of the mutual relations between the quality of soil and climatic conditions, which manifests...

Effects of Manure Use and Use Restrictions on Variable Production Costs and Net Incomes for U.S. Corn Producers
Provedor de dados: 31
Autores: Beckman,   Jayson F.; Livingston,   Michael J.
We utilize a treatment effects model to examine if there are differences in costs/profits for manure-using corn producers versus non-users. We find that manure users have lower peracre operating costs via reductions in fertilizer and soil conditioner costs; however, the use of manure reduces grain yields and ultimately leads to no difference in profit. Separate results indicate that manure-use restrictions do not affect costs or profits; thus policies could be in place to regulate manure usage without impacting the costs/profit structure of the farm.

Development of profitable milk production systems for northern Australia: an analysis of intensification of current systems
Provedor de dados: 31
Autores: Callow,   Mark N.; Gobius,   N.; Hetherington,   G.
Milk producers in northern Australia are attempting to make rapid adjustments to production systems that enable them to compete in a newly deregulated market, although there is uncertainty about how to do this. Through industry consultation and expert review a process was developed to identify production systems that may be capable of supporting economic targets of 10% return on assets and 600,000 L milk/labour unit. A broadly based project team in terms of disciplines then used this process to identify five production systems which were each applicable to substantial numbers of current milk producers. These were modelled using whole farm economic analyses and annual feed planning, using an iterative process over an extended period, to determine the...

Az ökológiai gazdálkodás költség-jövedelem viszonyait a hagyományos termeléssel összehasonlítva, modellszámítások alapján vizsgáltuk. A modellépítéshez szükséges adatokat Hortobágy térségében működő egyéni gazdálkodók körében gyűjtöttünk. Az egy hektárra jutó költségek összegében a két gazdálkodási mód között jelentőseltérések nem voltak, a költségek szerkezete azonban markáns különbségeket mutatott, amely a technológiák eltéréseivel magyarázható. Az ökológiai növénytermelésben a hozamok jellemzően alacsonyabbak voltak, az önköltség és az értékesítési árak viszont magasabbak. Egyik termelési mód sem bizonyult életképesnek támogatások nélkül, a bruttó jövedelem különbségeit azonban nem a támogatások, hanem elsősorban az eltérő hozamok és értékesítési árak...

Provedor de dados: 31
Autores: Cox,   Nicholas J.; Longton,   Gary M.
Distinct observations are those different with respect to one or more variables, considered either individually or jointly. Distinctness is thus a key aspect of the similarity or difference of observations. It is sometimes confounded with uniqueness. Counting the number of distinct observations may be required at any point from initial data cleaning or checking to subsequent statistical analysis. We review how far existing commands in official Stata offer solutions to this issue, and we show how to answer questions about distinct observations from first principles by using the by prefix and the egen command. The new distinct command is offered as a convenience tool.

Provedor de dados: 31
Autores: Cox,   Nicholas J.
Table-like graphs can be interesting, useful, and even mildly innovative. This column outlines some Stata techniques for producing such graphs. graph dot is likely to be the most under-appreciated command among all existing commands. Using by() with various choices is a good way to mimic a categorical axis in many graph commands. When graph bar or graph dot is not flexible enough to do what you want, moving to the more flexible twoway is usually advisable. labmask and seqvar are introduced as new commands useful for preparing axis labels and axis positions for categorical variables. Applications of these ideas to, e.g., confidence interval plots lies ahead.

Economic analysis of automatic flood irrigation for dairy farms in northern Victoria
Provedor de dados: 31
Autores: Armstrong,   Dan P.; Ho,   Christie K.M.
Interest in automatic flood irrigation is strong, given the labour and lifestyle benefits it can provide. An economic analysis of three automated flood irrigation systems for a dairy farm in northern Victorian indicated that automatic irrigation can be a profitable labour saving investment in many cases. However, profitability was sensitive to the amount and value of the labour saved. Pneumatic and timer systems were good investments regardless of the area they were installed to service. The supervisory control and data acquisition (SCADA) system was a good investment when more than 50 ha were serviced by the system. Irrigation water savings are unlikely to have a significant effect on the profitability of automatic irrigation, particularly if the price of...

Accommodating covariates in receiver operating characteristic analysis
Provedor de dados: 31
Autores: Janes,   Holly; Longton,   Gary M.; Pepe,   Margaret S.
Classification accuracy is the ability of a marker or diagnostic test to discriminate between two groups of individuals, cases and controls, and is commonly summarized by using the receiver operating characteristic (ROC) curve. In studies of classification accuracy, there are often covariates that should be incorporated into the ROC analysis. We describe three ways of using covariate information. For factors that affect marker observations among controls, we present a method for covariate adjustment. For factors that affect discrimination (i.e., the ROC curve), we describe methods for modeling the ROC curve as a function of covariates. Finally, for factors that contribute to discrimination, we propose combining the marker and covariate information, and we...

A nemnövekedés (degrowth) a fejlett országok számára ajánlott új gazdasági paradigma, amely hosszú távon bolygónk ökológiai fenntarthatóságát és az igazságosabb társadalmak kialakítását eredményezheti. A fogalom karrierje Latouche francia közgazdász 2006-os könyvével indult, amelyet két nemzetközi konferencia, négy latin nyelvű országban pedig politikai mozgalom is követett. Jelen cikk szerzője javasolja, hogy – az alulról jövő kezdeményezések mellett – valamelyik fejlett EU-tagállam is vállalja fel e mozgalom támogatását. A hazai agrárszakemberek a témakörön belül elsősorban az ökofalvakkal, az alacsony fogyasztású vidéki életmóddal és a szövetkezeti bankokkal kapcsolatos francia és spanyol kezdeményezéseket hasznosíthatják, amelyeket ők a nemnövekedés...

Accelerated Productivity Growth Offsets Decline in Resource Expansion in Global Agriculture
Provedor de dados: 31
Autores: Fuglie,   Keith O.
Rapid increases in agricultural commodity prices during 2006-08 raised concerns that agricultural productivity growth may not be keeping up with increasing demand for agricultural commodities. ERS has developed a new index of total factor productivity (TFP) in global agriculture to provide a more comprehensive understanding of longrun sources of agricultural output growth. ERS research shows that the average rate of growth in global agricultural TFP has accelerated in recent decades and accounts for an increasing share of growth in agricultural production. Faster TFP growth has offset declining growth in agricultural land, labor, and other resources, although TFP growth across countries and global regions remains unevenly distributed.

Az üzemek jellemzője továbbá a viszonylag kis méret, a saját földtulajdonra és családi munkaerőre alapozott munkavégzés, valamint a tudatos, piaci igényeket figyelembe vevő termelési szerkezet.

Autores: Banks,   Rob.
This paper contains my personal reflections as scientific editor of the livestock systems and technology section of the Australian Farm Business and Farming Systems Management Journal, i.e. AFBM Journal. It is the aim of this paper to highlight critical issues in defining the framework of opportunities for authors in the broad area of livestock systems and technology. The message within the description of current economic, marketing and technological conditions for farming is that only a limited proportion (about 20%) of the farming community has taken the opportunities that are available to achieve levels of profitability and efficiency sufficient to break the city: bush gap. However, when most farmers are working below profitability benchmarks, their...

Chinese consumer’s perceptions of beef
Provedor de dados: 31
Autores: Liu,   Hongbo; Parton,   Kevin A.; Cox,   Rodney J.
China has experienced rapid economic growth over the last 26 years. As per capita income has increased, household consumption has become greatly diversified, and many food new products have entered the market. Beef is slowly gaining ground relative to the more traditional pork products. This research examined factors affecting beef purchasing decisions in China. The effect of socioeconomic and demographic characteristics, together with other influences on preferences, was analysed using probit regression analysis. Compared with other meats, the relatively high price of beef (34%) and consumers’ unfamiliarity with its cooking method (26%) are the main limitations for beef consumption. These are followed by ‘don’t like the taste and smell’ which shows that...

Labor-Intensive U.S. Fruit and Vegetable Industry Competes in a Global Market
Provedor de dados: 31
Autores: Calvin,   Linda; Martin,   Philip L.
The U.S. fruit and vegetable industry is labor intensive, pays higher wages than are paid in many other countries, and increasingly operates in a global economy. U.S. fruit and vegetable farms rely on seasonal workers who are likely to be unauthorized immigrants; any future immigration reform could reduce the supply of labor or raise wages. Fruit and vegetable growers may respond to any potential wage increases by reducing the number of seasonal workers employed, adopting mechanized harvesters or other labor-saving technologies in the field, or reducing production.

Influence of Brand Equity on Milk Choice: A Choice Experiment Survey
Provedor de dados: 31
Autores: Taglioni,   Chiara; Cavicchi,   Alessio; Torquati,   Biancamaria; Scarpa,   Riccardo.
In the context of sustainable consumption buying local produce could support environmentally friendly production from the local economy. Our study estimates the preference weights that local consumers assign to some milk attributes including local origin and the influence on choice of a local brand of milk, which is traded by a local cooperative of producers in Umbria (Italy). Several preference segments are found amongst fresh and UHT milk buyers by employing a Latent Class model to analyze stated choice data. This specification allows us to verify whether consumers who have a better attitude towards local milk also prefer this brand to others, placing different values on the regional origin of milk.

Synchronized artificial insemination was used to inseminate cows using different types of sire genetics, including low-accuracy, calving-ease, and high-accuracy. These three sire groups were compared to calves born to cows bred using natural service. We found substantial production efficiency gains, carcass merit improvement, and economic value for calves of cows bred using a synchronized artificial insemination program with highaccuracy semen. The economic advantage of the high-accuracy sire group of calves was computed to be in the neighborhood of $40 to $80/head, relative to the natural service sire group of calves.

Case-study forty-year historical analysis of production and resource use on northern Victoria dairy farming
Provedor de dados: 31
Autores: Melsen,   Monique G.; Armstrong,   Dan P.; Ho,   Christie K.M.; Malcolm,   Bill; Doyle,   Peter T.
Recent analysis from surveys of dairy farms has shown that despite large increases in production, the productivity gains on these farms have been modest. Productivity gains are important for farm viability, farmers have made production gains through adoption of technologies and increases in scale. This long-term farm case study of an irrigated dairy farm over a 40-year period provides an in-depth analysis of system changes and management complexity. Detailed records of milk production, herd, farm area and infrastructure, water use, supplementary feed, and labour were collected and pasture consumption was estimated. Changes in milk production were analysed in relation to individual resources, particularly farm inputs. Increases in production were associated...

The starting point of the EDORA project was the recognition that, rather than becoming more uniform in character, rural Europe is, in many ways, becoming increasingly diverse, implying new challenges and opportunities. The project’s overarching aim was to examine the process of differentiation, in order to better understand how EU policy can enable rural areas to build upon their specific potentials to achieve ‘smart, sustainable and inclusive growth’. The first phase of the project consisted of a literature review in order to establish a conceptual framework for subsequent empirical analysis. This identified a very wide range of aspects of contemporary rural change. In order to manage this complexity, and so that it could be communicated simply and...

Autores: Rao,   I.V.Y. Rama.
The study has assessed the economics and sustainability of SRI (system of rice intensification) and traditional methods of paddy cultivation in North Coastal Zone of Andhra Pradesh for the period 2008-09, based on the data of costs and returns of crop. Apart from budgeting techniques, benefit-cost ratio (BCR), yield gap analysis, sustainability index and response priority index have been employed in the study. It has shown that BCR is higher for SRI (1.76) than traditional (1.25) methods. Further, there is a 31 per cent yield gap between SRI and traditional methods, in which cultural practices (20.15%) have shown a stronger effect than input use (10.85%). The most important constraint in SRI cultivation has been identified as ‘nursery management’. The SRI...

Autores: Armstrong,   Dan P.; Ho,   Christie K.M.; Doyle,   Peter T.; Malcolm,   Bill; Gibb,   I.; Brown,   Stuart.
The dairy industry in northern Victoria faced dramatic changes between 2001/02 and 2002/03. Drought resulted in a substantial decrease in availability, and subsequent increase in price, of irrigation water and supplementary feed. Most farms recorded substantial net cash flow deficits. Prior to 2002/03, a project had been established using case studies and a spreadsheet model to examine potential futures for different farm types. This approach was successfully adapted to examine drought impacts and recovery options under the vastly different prevailing circumstances. Several factors appear to have contributed to the adaptability of the approach, as follows: • The approach considered many aspects of farm management systems, but was simple enough to allow...

Azt vizsgáltuk, hogy a különböző mennyiségű, zsír- és fehérjetartalmú tejet termelő szarvasmarhafajták (holstein-fríz, magyar tarka, jersey) esetében miképpen alakulnak a tejtermelés bevételei és költségei, valamint azt, hogy a koncentráltabb tejért fizetett felárak és a feldolgozásukban jelentkező költségmegtakarítás milyen arányban állnak egymással. Megállapítható volt, hogy a tehenészetek mindhárom fajtánál, a jelenlegi árviszonyok mellett, némi jövedelmet csak a költségvetési támogatásoknak köszönhetően érnek el. A tejtermelésben a fajták versenyképessége legpontosabban a termelési érték és a takarmányköltség különbözete alapján ítélhető meg, az egyéb költségek többségének alakulása ugyanis nem a fajtától függő.

Energy consumption in the United Sates has been increasing and the cost of fossil fuels has been unstable in recent years. Expanding investment in renewable energy is one way to reduce the nation’s dependence on fossil fuels. However, the Not-In-My-Back- Yard (NIMBY) opposition and various concerns raised at public hearings may inhibit the expansion of wind energy in Illinois. This study aims to characterize the public beliefs and opinions toward wind energy in central Illinois.

Organic Dairy Sector Evolves To Meet Changing Demand
Provedor de dados: 31
Autores: McBride,   William D.; Greene,   Catherine R.
Declining demand for organic products in response to the economic downturn has slowed the rapid growth in organic milk production. Economic forces, primarily lower production costs, may be pushing organic dairies to be more like conventional dairies in terms of size, location, and the types of technologies used. More specific pasture requirements for organic certification proposed under USDA’s National Organic Program may affect how the organic milk production sector evolves.

Social benefit cost analysis of Dairy Moving Forward extension activity
Provedor de dados: 31
Autores: Malcolm,   Bill; Paine,   Mark.
Dairy Australia has delivered a program entitled DMF involving a series of activities to enhance the expertise of dairy farmers and encourage their use of expert services. A substantial investment of $5.2m (adjusted to 2005 dollars) has been made by Dairy Australia in the program. In this report, justifications for DA using farmers’ and taxpayers’ funds in this way are explored; a Social Benefit Cost Analysis has been carried out. The conclusion is that the public and industry investment in DMF is likely to have earned a return on capital that justifies the investment.

Public Research Yields High Returns... Measured in More Than Dollars
Provedor de dados: 31
Autores: Heisey,   Paul W.; King,   John L.; Day-Rubenstein,   Kelly A.
Well-established quantitative approaches find that in the aggregate, public investments in agricultural research yield high returns and spur growth in agricultural productivity. Standard economic approaches may be difficult to apply to evaluations of some research benefits and may not help in gauging important steps necessary to positive research outcomes. In these more difficult cases, economic reasoning can provide qualitative analysis even when quantitative estimates of benefits are intractable.

A comparison of the economic and environmental performances of conventional and organic farming: evidence from financial statements
Provedor de dados: 31
Autores: Argiles,   Josep M.; Brown,   Nestor Duch.
While conventional farming systems face serious problems of sustainability, organic agriculture is seen as a more environmentally friendly system since it favours renewable resources, recycles nutrients, uses the environment’s own systems for controlling pests and diseases, sustains ecosystems, protects soils, and reduces pollution. At the same time organic farming promotes animal welfare, the use of natural foodstuffs, product diversity and the avoidance of waste, among other practices. However, the future of organic agriculture will depend on its economic viability and on the determination shown by governments to protect these practices. This paper performs panel regressions with a sample of Catalan farms (Spain) to test the influence of organic farming...

Multivariate random-effects meta-analysis
Provedor de dados: 31
Autores: White,   Ian R.
Multivariate meta-analysis combines estimates of several related parameters over several studies. These parameters can, for example, refer to multiple outcomes or comparisons between more than two groups. A new Stata command, mvmeta, performs maximum likelihood, restricted maximum likelihood, or method-of-moments estimation of random-effects multivariate meta-analysis models. A utility command, mvmeta_make, facilitates the preparation of summary datasets from more detailed data. The commands are illustrated with data from the Fibrinogen Studies Collaboration, a meta-analysis of observational studies; I estimate the shape of the association between a quantitative exposure and disease events by grouping the quantitative exposure into several categories.

The impact of management skills on farm incomes in Canada
Provedor de dados: 31
Autores: Painter,   Marvin J.
This study assesses the reported farm income crisis in Canada and uses farm financial data to illustrate the importance and impact that management skills and practices have on farm income and net worth. For grain and oilseed farms, large farms produce higher revenues per hectare and achieve economies of scale on operating expenses, interest and depreciation, making them significantly more profitable than smaller or average sized farms. The higher profits associated with large farms are partly returns to good farm management. While farmland investment returns are competitive with stock and bond markets, grain and oilseed farm labour and management returns are not competitive with provincial average wages and salaries. On average, Canadian grain and oilseed...

Autores: Jann,   Ben.
The counterfactual decomposition technique popularized by Blinder (1973, Journal of Human Resources, 436–455) and Oaxaca (1973, International Economic Review, 693–709) is widely used to study mean outcome differences between groups. For example, the technique is often used to analyze wage gaps by sex or race. This article summarizes the technique and addresses several complications, such as the identification of effects of categorical predictors in the detailed decomposition or the estimation of standard errors. A new command called oaxaca is introduced, and examples illustrating its usage are given.

Measuring producer welfare under output price uncertainty and risk non-neutrality
Provedor de dados: 31
Autores: Bullock,   David S.; Garcia,   Philip; Shin,   Kie-Yup.
Procedures to measure the producer welfare effects of changes in an output price distribution under uncertainty are reviewed. Theory and numerical integration methods are combined to show how for any form of Marshallian risk-responsive supply, compensating variation of a change in higher moments of an output price distribution can be derived numerically. The numerical procedure enables measurement of producer welfare effects in the many circumstances in which risk and uncertainty are important elements. The practical ease and potential usefulness of the procedure is illustrated by measuring the producer welfare effects of USA rice policy.

Autores: Stevens,   David R.; Casey,   M.J.; Brown,   C.D.; Platfoot,   G.J.
Rapid dairy industry expansion in the South Island of New Zealand during the 1990’s increased demand for agistment and supplementary feed. Consultants and retailers recognised the ability of whole-crop cereal silage to provide the extra feed required. The local arable industry had declined, creating the opportunity to develop commercial technical support packages from establishment to harvesting for sheep and dairy farmers growing whole-crop cereal silage. Industry technical support packages were supported by ‘just in time’ local research into the growing, making and feeding of whole-crop cereal silage. The package, based on several methods of payment, captured the benefits of new Triticale cultivars. Further investigation into the uptake of whole-crop...

The Influence of Clusters on the Competitiveness of Hog Production: The Example of Northwestern Germany
Provedor de dados: 31
Autores: Deimel,   Mark; Arens,   Ludwig; Theuvsen,   Ludwig.
In recent decades the northwestern part of Germany (Weser-Ems region) has come to focus on intensive pork production. This has led to public outrage about the disposal of biological waste, farmers’ complaints about the high cost of leasing land, soaring risks of animal diseases, and the decreasing popularity of intensive animal husbandry. However, despite these problems, due to a beneficial cluster structure, the region is a successful market participant. To shed some light on the relationship between network relationships in clusters and competitiveness, an empirical survey was undertaken to compare this pork-intensive region with non–pork-intensive regions. Bi- and multivariate analyses reveal a better access to knowledge and information on the part of...

Economic Impact of Wildlife-Associated Recreation Expenditures in the Southeast United States: A General Equilibrium Analysis
Provedor de dados: 31
Autores: Hussain,   Anwar; Munn,   Ian A.; Holland,   David W.; Armstrong,   James; Spurlock,   Stanley R.
The economic impact of wildlife-associated recreation in the Southeast United States was evaluated using a general equilibrium model. Exogenous demand shocks to the regional economy were based on estimates of expenditures by wildlife recreationists on hunting, fishing, and wildlife watching activities. Counterfactual simulations were carried out, making alternative assumptions about labor and capital mobility and their supply. Without wildlife-associated recreation expenditures, regional employment would have been smaller by up to 783 thousand jobs, and value added would have been $22 to $48 billion less. These findings underscore the significance of regional factor market conditions in economic impact and general equilibrium analysis.

A Hybrid Land Conversion Model Incorporating Multiple End Uses
Provedor de dados: 31
Autores: Kaza,   Nikhil; Towe,   Charles A.; Ye,   Xin.
The need for models that forecast land use change spans many disciplines and encompasses many approaches. Pattern-based models were the first in which projections of change at specific locations in actual landscapes could be predicted. In contrast, recent economic models have modeled the underlying behavioral process that produces land use change. This paper combines attributes from each approach into a hybrid model using a multiple discrete continuous extreme value formulation that allows for multiple conversion types, while also estimating the intensity of each type of conversion, which is an important but often overlooked dimension. We demonstrate the simulation routine, which successfully predicts a majority of growth by type, time, and location at a...

Sensitivity analysis for average treatment effects
Provedor de dados: 31
Autores: Becker,   Sascha O.; Caliendo,   Marco.
Based on the conditional independence or unconfoundedness assumption, matching has become a popular approach to estimate average treatment effects. Checking the sensitivity of the estimated results with respect to deviations from this identifying assumption has become an increasingly important topic in the applied evaluation literature. If there are unobserved variables that affect assignment into treatment and the outcome variable simultaneously, a hidden bias might arise to which matching estimators are not robust. We address this problem with the bounding approach proposed by Rosenbaum (Observational Studies, 2nd ed., New York: Springer), where mhbounds lets the researcher determine how strongly an unmeasured variable must influence the selection...

China’s agriculture, smallholders and trade: driven by the livestock revolution?
Provedor de dados: 31
Autores: Rae,   Allan N.
China’s sustained rapid economic growth and development has contributed to the surge in consumption and production of livestock in that country termed the livestock revolution. Consumption trends are first reviewed, and changes in food consumption patterns include a marked shift away from grains and towards meats and dairy products. A question is to what extent this rapid increase in demand for livestock products is reflected in China’s agri-food trade statistics? While her agri-food imports have dramatically increased since China’s accession to the WTO, livestock products have not made a noticeable contribution, although the import of certain animal feedstuffs has. This implies China’s continuing self-sufficiency in most livestock products. The paper next...

The paper deals with the analysis of market land prices that were collected from land purchased contracts in the Czech Republic. Regression model was used to identify determinants explaining variability of market prices between 2008 and 2009. It was found out that type of plantation, region, type of buyers, plot size, distance to regional city or number of parcels play significant role. These factors explain more than a half of variance in land price. Quality of land that was expressed through administrative price has significant effect on market price. Yet, such effect became less import in regions nearby cities (e.g. Prague and Olomouc), where the market land price is significantly influenced by the distance to the district city. Land reform, however has...

Autores: Bai,   Junfei; Wahl,   Thomas I.; McCluskey,   Jill J.
This study relates the social-demographic characteristics of urban Chinese consumers to their consumption of fluid milk. A Tobit model is estimated drawing on individual consumer survey data collected in urban Qingdao in China in 2005. The major results of this study indicate that fluid milk consumption in urban Qingdao is much higher compared to China’s national level. The effect of increased income on milk consumption is positive, as expected. The expansion of modern food retailers also appears to play a positive role by facilitating consumers’ fluid milk consumption and influencing their food shopping patterns. The young and old consume significantly more fluid milk than the middle-aged. Health consciousness of the elderly and the openness of youth to...

Using urban survey data collected by the authors in 2001–02, this paper analyses demographics, cultural factors and purchasing behaviours influencing the consumption of fresh milk, yogurt, ice cream and powered milk in Beijing, Shanghai and Guangzhou, China. Results from estimation of a double-hurdle model of consumption show that income and marketing channels are the key determinants of milk consumption levels; however, education, advertising and convenience play a more important role in consumption of other dairy products. There is some evidence that milk powder, as a consumer good, may be becoming an inferior product in urban China. Finally, the survey data suggest that the growing sophistication of China’s retail sector is influencing consumption of...

An exact and a Monte Carlo proposal to the Fisher–Pitman permutation tests for paired replicates and for independent samples
Provedor de dados: 31

This article concerns the nonparametric Fisher–Pitman tests for paired replicates and independent samples. After outlining the theory of exact tests, I derive Monte Carlo simulations for both of them. Simulations can be useful if one deals with many observations because of the complexity of the algorithms in regard to sample sizes. The tests are designed to be a more powerful alternative to the Wilcoxon signed-rank test and the Wilcoxon–Mann–Whitney rank-sum test if the observations are given on at least an interval scale. The results gained by Monte Carlo versions of the tests are accurate enough in comparison to the exact versions. Finally, I give examples for using both supplemented tests.

Achieving the U.S. goal to triple biofuel use by 2022 will depend on rapid expansion in cellulosic biofuels, and U.S. agriculture, as a leading source of the Nation’s biomass, will play a significant role in this expansion. The U.S. Environmental Protection Agency announced that the cellulosic biofuel mandate for 2010 would be reduced from 100 million gallons to 6.5 million gallons. Blending and shipping constraints may encourage investors to turn away from cellulosic ethanol in favor of processes that yield green fuels, more closely substitutable for fossil fuels.

Then, the farming sector is analysed, both with respect to its productive and factor characteristics, and the farm population features, over the period of systemic transformation. It is noted that farming intensity has gone down altogether on almost all accounts, while privatisation of farming has been overwhelming. At the same time, during the transformation, there have been disadvantageous phenomena within the farm...

Capturing benefits from water entitlement trade in salinity affected areas: A role for trading houses?
Provedor de dados: 31
Autores: Bell,   Rosalyn.
While there is potential for substantial benefits from water entitlement trade, external effects such as salinity may mean that traders cannot capture these benefits. This paper demonstrates that by creating a trading house as a single seller of water entitlements, with trade profits distributed to buyers, it is possible to achieve an allocation of entitlements which gives a social outcome higher than that possible from atomistic competition for entitlements. Such an outcome may be comparable to an optimally set uniform charge for water entitlements, but the trading house mechanism has the advantage that it makes use of trade to generate information on the optimal level of charging in the presence of salinity.

Rapid urbanization enhances the desirability of policies for preserving open space but policies intended to preserve open space may extend the urban boundary and create leapfrog development. We investigate this potential conflict between open space preservation and urban sprawl conceptually and empirically using data from the Baltimore-Washington suburbs. In accord with previous theoretical and empirical results, the estimated econometric model indicates that both zoning and forest planting requirements contribute to sprawl by increasing the amount of land needed to accommodate the current number of households. These results point to a conflict between preserving open space incorporated into private building lots or internal to sub-divisions and public...

El modelo de ayudas directas en la PAC post-2013: análisis de impactos de escenarios potenciales
Provedor de dados: 31
Autores: Blanco,   Maria; Garcia-German,   Sol; Bardaji,   Isabel.
Following their introduction in 1992, direct payments have become one of the main instruments of the Common Agricultural Policy. The aim of this study is to analyse potential scenarios of harmonization of direct payments in the CAP post-2013. In doing so, we use the CAPRI model, which represents the functioning of agricultural markets at the global level and simultaneously models CAP measures at the EU regional level. Results suggest that while a flatter rate of direct payments would have minor impacts on agriculture at the EU level, it would imply substantial redistributive effects, both across regions and Member States.

Do Farm Programs Encourage Native Grassland Losses?
Provedor de dados: 31
Autores: Claassen,   Roger; Carriazo,   Fernando; Cooper,   Joseph C.; Hellerstein,   Daniel.
Federal programs may encourage farmers to convert native grasslands—land that has never been cultivated — to production of corn, soybeans, and other crops, leading to potential losses of Northern Plains' native grasslands. Federally subsidized crop insurance reduces risk associated with crops grown on converted grasslands and, over time, increases average returns to production by making crop farming more attractive. Other programs, including Federal disaster assistance and marketing loan benefits, also reduce risk and increase returns to crop production on converted grasslands. While these programs can be important risk management tools for farmers, they may also result in unintended, environmentally damaging actions.

Factors Affecting Adoption of Monocropping of Rice in Manipur: A Logistic Approach
Provedor de dados: 31
Autores: Sarungbam,   Diana; Prasad,   Y.E.
The study conducted in the state of Manipur, has identified the factors affecting monocropping of rice as the cropping intensity of the state is only 107 per cent. Multistage random sampling has been followed to select the districts, blocks, villages and finally the farmers and logit model has been used for the analysis. The study has observed that availing of institutional credit and educational level are among the important factors which decrease monocropping. The study has highlighted the need for focus on crop diversification and increasing cropping intensity. Strengthening of co-operative societies, increasing availability and accessibility to credit facilities, increasing awareness about new technologies, etc. will help in increasing the cropping...

The Implications of Skewed Risk Perception for a Dutch Coastal Land Market: Insights from an Agent-Based Computational Economics Model
Provedor de dados: 31
Autores: Filatova,   Tatiana; Parker,   Dawn Cassandra; van der Veen,   Anne.
Dutch coastal land markets are characterized by high amenity values but are threatened by potential coastal hazards, leading to high potential damage costs from flooding. Yet, Dutch residents generally perceive low or no flood risk. Using an agent-based land market model and Dutch survey data on risk perceptions and location preferences, this paper explores the patterns of land development and land rents produced by buyers with low, highly skewed risk perceptions. We find that, compared to representative agent and uniform risk perception models, the skewed risk perception distribution produces substantially more, high-valued development in risky coastal zones, potentially creating economically significant risks triggered by the current Dutch flood...

Hidden action, risk aversion and variable fines in agri-environmental schemes
Provedor de dados: 31
Autores: Ozanne,   Adam; White,   Benedict.
This note analyses the design of agri-environmental schemes for risk-averse producers whose input usage is only observable by costly monitoring. The scheme penalises producers in proportion to input use in excess of a quota. A striking result is that if the scheme is designed in such a way that producers always comply with the quota, risk aversion is not relevant in determining the level of input use.

Making regression tables simplified
Provedor de dados: 31
Autores: Jann,   Ben.
estout, introduced by Jann (Stata Journal 5: 288–308), is a useful tool for producing regression tables from stored estimates. However, its syntax is relatively complex and commands may turn out long even for simple tables. Furthermore, having to store the estimates beforehand can be cumbersome. To facilitate the production of regression tables, I therefore present here two new commands called eststo and esttab. eststo is a wrapper for official Stata’s estimates store and simplifies the storing of estimation results for tabulation. esttab, on the other hand, is a wrapper for estout and simplifies compiling nice-looking tables from the stored estimates without much typing. I also provide updates to estout and estadd.

Economic Analysis of Post-harvest Losses in Marketing of Vegetables in Uttarakhand
Provedor de dados: 31
Autores: Sharma,   Gaurav; Singh,   S.P.
The study has examined the nature and extent of post-harvest losses in vegetable supply chain in the Kumaon division of Uttarakhand. Multistage cluster sampling has been used for selection of 80 vegetable growers, 40 farmers from the hilly region and 40 farmers from the bhabhar region. The sample has also included 25 market functionaries. Twelve major vegetables have been selected for the study. The maximum aggregate post-harvest losses have been found in tomato, followed by potato, brinjal, chilly, French bean and pea. The study has suggested that establishment of producer co-operatives to handle various activities relating to production and marketing of vegetables would help in reducing post-harvest losses.

Social Meaning in Supermarkets as a Direct Route to Improve Parents’ Fruit and Vegetable Purchases
Provedor de dados: 31
Autores: Payne,   Collin R.; Niculescu,   Mihai.
Direct and indirect attempts to increase parents’ fruit and vegetable purchases have had little, if any, success. Most of the disappointing results are reported in the grocery environment. In this context, embedding messages with social meaning may have a significant impact on current campaigns. We use the focus theory of normative conduct as an alternative theoretical framework and suggest that social norms that are salient, easy to interpret, and easy to compare against individuals’ behavior may improve current attempts to increase parents’ fruit and vegetable purchases in retail environments.

Tajikistan, with 93% of its surface area taken up by mountains and 65% of its labor force employed in agriculture, is judged to be highly vulnerable to risks, including climate change risks and food insecurity risks. The article examines a set of land use policies and practices that can be used to mitigate the vulnerability of Tajikistan’s large rural population, primarily by increasing family incomes. Empirical evidence from Tajikistan and other CIS countries suggests that families with more land and higher commercialization earn higher incomes and achieve higher well-being. The recommended policy measures that are likely to increase rural family incomes accordingly advocate expansion of smallholder farms, improvement of livestock productivity, increase...

An Exploration of the Relationship Between Income and Eating Behavior
Provedor de dados: 31
Autores: Chen,   Susan E.; Liu,   Jing; Binkley,   James K.
This paper explores the relationship between income and eating behavior. To do this we examine choice in two food categories: milk and soft drinks. These categories have varieties differing in health qualities but either no differences in cost or lower cost for the healthier types. By examining food choices when there are no measurable cost differences but clear health differences, we are able to isolate the association between income and healthy eating behavior. We find a negative association between income and dietary intake of higher-calorie types of milk and soft drinks. Our estimates are consistent across the five sets of the National Health and Nutrition Examination Survey and the Continuing Survey of Food Intakes by Individuals data that we study....

Autores: Villano,   Renato A.; Fleming,   Euan M.; Rodgers,   Heidi.
Productivity change and real returns to resources are measured for a sample of farms in south-west Victoria that produce beef. A stochastic frontier production model is estimated from which annual production frontiers and individual farm technical inefficiencies are calculated during the survey period from 1995-96 to 2004-05. Results suggest that best-practice beef producers in this region (those operating on the production frontier) modestly improved their productivity during the period. Technically inefficient farms seem to be achieving productivity increases lower than their top-performing counterparts and are on average falling behind the productivity levels of the latter. A single factoral terms of trade index is also estimated for each farm as a...

Removing border protection on wheat and rice: effects on rural income and food self-sufficiency in China
Provedor de dados: 31
Autores: Mai,   Yinhua.
In this paper, I use the Monash Multi-Country model – a dynamic Computable General Equilibrium model of China, Australia and the Rest of the World – to analyse the effects of removing border protection on wheat and rice in China. The analysis points to the possibility that removing border protection on wheat and rice may lead to an increase in rural income in China. This is mainly due to the following two factors. First, removing border protection on wheat and rice not only leads to a contraction in agricultural activities, but also leads to an expansion in manufacturing and services activities. Second, on average, rural households in China obtain over half of their income from manufacturing and services activities.

This article evaluates the cost-effectiveness of the Catchment Care Australian conservation auction. It provides evidence of auction cost effectiveness, and estimates cost savings from two discrete components: (i) the opportunity cost revelation incentive provided by the auction mechanism, and (ii) the improved environmental targeting capacity that results from development of a scientifically based environmental benefits assessment capacity. Results show that there are potentially very large returns associated with the latter component that have been overlooked in the literature. Additionally, transaction costs involved with administering the case study conservation auction and the prior non-auction payment policy are compared. We find that the...

Average total factor productivity measures for the dairy industry provide an insight into how the industry is performing as a whole, but reveal little about what may be happening on individual farms. A case study of an irrigated dairy farm in northern Victoria, over a 37-year period, found that total milk production and some measures of partial productivity increased substantially. The economic performance of this case study farm over the 37-year period is described and analysed. From records of income and expenses, operating profit, returns to capital, labour and management and total productivity measures were calculated. Between 1980 and 2000, the business achieved productivity gains at higher than the rate estimated for the whole industry. This...

The Role of Information and Prices in the Nitrogen Fertilizer Management Decision: New Evidence from the Agricultural Resource Management Survey
Provedor de dados: 31
Autores: Williamson,   James M.
This article investigates the impact of agronomic and price information on nitrogen fertilizer management. Excessive nitrogen applications can cause environmental degradation, and it is important to understand how information influences the application decision in order to develop effective conservation policies. The impact of soil N-tests on the rate of applied nitrogen is estimated. Farmers who use a soil test reduce their use of commercial nitrogen by up to 83 lbs/acre relative to non-testers. New evidence indicates that rising fertilizer prices encourage farmers to manage nitrogen more carefully. Estimated price elasticities of quantity demanded range from -1.67 to -1.87.

Ecological engineering has recently emerged as a paradigm for considering pest management approaches that are based on cultural practices and informed by ecological knowledge rather than on high technology approaches such as synthetic pesticides and genetically engineered crops (Gurr et al. 2004a). This article provides a brief summary of ecological engineering for arthropod pest management and contrasts it with its controversial cousin, genetic engineering. The development of ecological engineering is explored, ranging from a simple first approximation that diversity is beneficial, to contemporary understanding that diversity can have adverse effects on pest management. This requires that the functional mechanisms that lead components of biodiversity to...

Trade Policy Implications of Carbon Labels on Food
Provedor de dados: 31
Autores: Baddeley,   Shane; Cheng,   Peter; Wolfe,   Robert.
Carbon labels providing information about the carbon footprints associated with food products might influence consumer purchases, which would have a differential effect on producers throughout global food chains. We first discuss why any labels work and then describe the mechanics of carbon labels. The novelty of the paper is an examination of the issues members of the WTO have raised about all types of labels since 1995. Although carbon labels are voluntary standards for now, their increasing use could become effectively mandatory. Difficulties for exporters will include the lack of an international standard and the challenge, especially for developing country exporters, of dealing with complex carbon footprint procedures.

This paper reports and discusses the results of a survey conducted among experts working in the field of decision support systems (DSS) in Australian agriculture. It also reviews the literature on DSS in the light of these experts’ responses. The findings from this survey have consolidated our understanding of the current state of DSS in Australian agriculture. The uptake of DSS by farmers has been slow and various issues said to be contributing to this include fear of using computers, time constraints, poor marketing, complexity, lack of local relevance, lack of end-user involvement, and mismatched objectives between developers and users. The future prospects for the development of DSS were generally regarded as poor. Nevertheless, the authors believe...

Against the background of increasing competitive pressures and growing requirements with regard to food quality and safety, the significance of network-wide collaboration in food production has been pointed out in recent years. With this in mind, it is the objective of this paper to analyse pig farmers’ network participation in general and to explore whether cooperative structures in food supply chains influence the type as well as the quality of farmers’ network relations. Our results show that cooperative structures influence pig fattening farmers’ network participation concerning relationship quality with slaughterhouses as well as farmers’ choice of network partners for information exchange and consultancy. Furthermore, the results show that farmers...

The value of health protocol certification may vary with certifying entity. Results from a choice experiment and survey of cattle feeders indicate preconditioning programs that include weaning, vaccinating against respiratory and clostridial/blackleg, and treating for parasites are worth on average $7.28/cwt to feedlots. Furthermore, a health program certified by USDA carries an additional value of $2.37/cwt on average.

The Two Faces of Rural Population Loss Through Outmigration
Provedor de dados: 31
Autores: McGranahan,   David A.; Cromartie,   John; Wojan,   Timothy R.
Over a third of nonmetropolitan counties lost more than 10 percent of their population over the past 20 years through net outmigration. Poverty and low education account for the high net outmigration in some of these counties, but most are relatively prosperous. Their outmigration is related to low population density, geographic isolation, and a lack of scenic amenities. Programs that reduce the disadvantages of geographic isolation and that enhance residents' access to scenic amenities could help slow or reverse net outmigration in many nonmetro counties.

Az élelmiszerlánc szereplői közötti kapcsolatok hazánkban

Hazánkban a válság miatt a keresleti oldalról növekedni képtelen piacon a kiskereskedelmi szereplők a kötelező éves növekedést immár csak a piac újraosztásával érhetik el, ami a kiskereskedők között kíméletlen – horizontális – versenyt eredményez. Ennek eszköze az alapvető termékek esetében a minél alacsonyabban tartott ár. Ezért a kereskedelmi láncok és beszállítóik kapcsolata vegyes képet mutat. A nagy, tőkeerős, elsősorban nemzetközi élelmiszer-feldolgozók és mezőgazdasági beszállítók számára még így is jövedelmező lehet a kereskedelmi láncok által biztosított széles körű piaci jelenlét. Ezzel szemben a hazai szinten nagy, de nem elég tőkeerős hazai beszállítók alkupozíciója rendkívül kényes, számukra még veszteség mellett is létkérdés a kereskedelmi...

The Food Costs of Healthier School Lunches

The U.S. Department of Agriculture proposed and adopted a new set of meal pattern requirements for the National School Lunch Program that will allow schools to claim 6 cents more in lunch reimbursement rates. This study analyzes the food costs of school menus in 2005 that met many of the proposed requirements. Overall, schools that served more, and more diverse, non-starchy vegetables had higher average food costs, and schools that served menus with lower calories had lower food costs. The food costs of school lunch menus that met the combined standards for dark green vegetables, orange vegetables, other vegetables, lowfat/fat-free milk, and fruit averaged 9 cents more per meal in 2005 dollars when other major factors that could affect food choices are...

In this paper an extensive review of the theoretical and applied literature on natural resource accounting (NRA) is provided. The review begins by explaining the economic theory that underpins NRA, contrasting welfare and sustainability as policy goals, and presenting various distinct conceptions of national income. The state of play regarding official revisions to the system of national accounts (SNA) with respect to natural resources and the environment is presented and controversial areas are highlighted. Finally, the economic literature on proposed revisions, and applied studies that have proceeded using these methods, is summarised and critiqued. We argue that much of the literature proceeds with weak conceptual foundations, and that typical case...

Labour Demand and Labour-saving Options: A Case of Groundnut Crop in India
Provedor de dados: 31
Autores: Govindaraj,   G.; Mishra,   A.P.
Groundnut is a labour-intensive crop, especially for operations like sowing, weeding, harvesting, and drying. But, of-late, due to timely unavailability of labour, many farmers are not able to exercise timely operations resulting in low yield realization. The present study conducted in two major groundnut-growing states, viz. Gujarat and Andhra Pradesh, has revealed that farmers employ more human labour in weeding and harvesting operations in groundnut than in other operations. The practise of manual decortication and stripping is followed by a larger number of farmers in Andhra Pradesh than in Gujarat, indicating less mechanization in the former. For weeding, though, the human labour-use in weedicide + bullock intercultivation + hand weeding technique is...

Access to Local Agriculture and Weight Outcomes
Provedor de dados: 31
Autores: Berning,   Joshua P.
Recent studies examine the impact of the built environment on health outcomes such as obesity. Several studies find for certain populations that access to unhealthy food has a positive effect on obesity, whereas access to healthy choices has a negative effect. Given the growth and popularity of locally grown food, we examine how individual weight outcomes are affected by access to direct-to-consumer local food. After controlling for potential endogeneity, we find that greater access to local food has a negative association with individual weight outcomes. We also find a negative association with greater weight loss over a one-year period. These results provide evidence that local food access can have potential indirect benefits.

Irrigation, poverty and inequality in rural China
Provedor de dados: 31
Autores: Huang,   Qiuqiong; Dawe,   David; Rozelle,   Scott; Huang,   Jikun; Wang,   Jinxia.
This paper examines the impact of irrigation on rural incomes, poverty and the income distribution in rural China. The relationship between irrigation and income is examined using descriptive statistics and multivariate analysis. A simulation approach is used to explore the impact of irrigation on poverty incidence. To uncover the effect of irrigation on the income distribution, inequality is decomposed by source of income, by group according to access to irrigation and by estimated income flows as a result of specific household characteristics. The results show that irrigation increases income and reduces poverty and inequality.

Do U.S. Cotton Subsidies Affect Competing Exporters? An Analysis of Import Demand in China
Provedor de dados: 31
Autores: Muhammad,   Andrew; McPhail,   Lihong Lu; Kiawu,   James.
We estimate the demand for imported cotton in China and assess the competitiveness of cotton-exporting countries. Given the assertion that developing countries are negatively affected by U.S. cotton subsidies, our focus is the price competition between the United States and competing exporters (Benin, Burkina Faso, Chad, Mali, India, and Uzbekistan). We further project how U.S. programs affect China’s imports by country. Results indicate that if U.S. subsidies make other exporting countries worse off, this effect is lessened when global prices respond accordingly. If subsidies are eliminated, China’s cotton imports may not fully recover from the temporary spike in global prices.

A shortcut through long loops: An illustration of two alternatives to looping over observations
Provedor de dados: 31
Autores: Vanlaar,   Ward.
It is well known that looping over observations can be slow and should be avoided. The objective of this article is to discuss two alternative solutions to looping over observations that can be used to overcome a particular data-management problem of merging datasets in which unique key identifiers changed over time. The first alternative, mapch, which is introduced in this article, uses a combination of appending, indexing, and merging to solve the problem, while the second alternative uses repeated merging. Both solutions are much quicker than looping over observations. However, depending on the nature of the problem, one solution may work better than the other. It is argued that the use of such dataset-type manipulations may be suitable to overcome...

This paper examines the composition of China’s international trade from 1980 to 1997, with a focus on agriculture and a view towards understanding agriculture’s changing trade structure relative to other sectors. We analyse the time series behaviour of individually traded goods at the Standard Industrial Trade Classification three‐digit level, categorised into three groups: agricultural commodities, ‘other’ primary commodities and manufactures. We find that China’s agricultural trade has expanded along comparative advantage lines in only a very modest way, suggesting that World Trade Organization membership will have a large impact on China’s agricultural trade patterns.

Optimal management of the New Zealand longfin eel (Anguilla dieffenbachii)

Autores: Doole,   Graeme J.
Annual recruitment of the NewZealand longfin eel (Anguilla dieffenbachii) hasdecreased by 75 per cent since significant levels of commercial fishing began in the early 1970s. This motivates application of a multiple-cohort bioeconomic model to a New Zealand longfin eel fishery to investigate its optimal management and ascertain the suitability of existing regulatory policy. The use of historical harvest to calculate total allowable catch is asserted to be unsustainable based on recovery dynamics. In addition, individual transferable quota systems are argued to be fundamentally flawed for the protection of longfin fisheries because of high-grading, low-surplus production and a current lack of effective stock-assessment procedures. Area closure and the...

While a proposed Murray-Darling Basin plan has been released, water sharing agreements will continue to evolve and much detail remains to be worked out as part of implementation at the state level. Given this, we seek to synthesise current research on the costs and benefits of the Murray-Darling Basin plan.

Policy reform and farmers' wheat allocation in rural China: a case study
Provedor de dados: 31
Autores: Buschena,   David E.; Smith,   Vincent H.; Di,   Hua.
Market-oriented policy reforms often have important effects on farm-level grain production and utilisation decisions in developing countries. China’s grain farmers are of particular interest because of China’s importance in world grain markets and because of China’s recent major agricultural policy advances and retrenchments. An empirical evaluation of market liberalisation among farmers located in two provinces in China on farm-level wheat consumption, market sales and on-farm storage during 1994 is presented. The results indicate that policymakers should account for such changes in farm household behaviour in designing and assessing the consequence ofmarket liberalisation programs for agricultural sectors in developing countries.

Ronald Aylmer Fisher suggested transforming correlations by using the inverse hyperbolic tangent, or atanh function, a device often called Fisher’s z transformation. This article reviews that function and its inverse, the hyperbolic tangent, or tanh function, with discussions of their definitions and behavior, their use in statistical inference with correlations, and how to apply them in Stata. Examples show the use of Stata and Mata in calculator style. New commands corrci and corrcii are also presented for correlation confidence intervals. The results of using bootstrapping to produce confidence intervals for correlations are also compared. Various historical comments are sprinkled throughout.

As patents and other forms of intellectual property become more pervasive in the next generation of biotechnologies, designing policies and practices to ensure sufficient freedom to operate (i.e., the ability to practice or use an innovation) will be crucial for non-profit research agencies, especially those intent on developing technologies destined for commercial release. Are non-profit organisations exempt from intellectual property claims? What constitutes infringement of a patent? How does a non-profit establish its freedom to operate? We address these issues in this paper and evaluate various options for accessing other people’s technologies.

Consumer versus citizen preferences in contingent valuation: evidence on the role of question framing
Provedor de dados: 31
Autores: Ovaskainen,   Ville; Kniivila,   Matleena.
Rather than individual consumer preferences, responses to referendum-style contingent valuation surveys on environmental goods may express citizen assessments that take into account benefits to others. We reconsider the consumer versus citizen hypothesis with a focus on the role of framing information. Survey data on conservation areas in Ilomantsi, Finland, are used. Different versions of the valuation question were used to encourage the respondents to take the consumer or the citizen role. The citizen version expectedly resulted in substantially fewer zero-WTP responses and protests and higher mean and median WTP, suggesting that the framing information has a major effect on the preferences expressed. The findings support the idea of multiple...

Provedor de dados: 31
Autores: Guo,   Xiao-ting.
From the point of view of industrial market structure, we analyze the influence of market structure on grain production, circulation, and processing, and on the grain pricing power of entities along China's grain industrial chain. Through analysis, it is indicated that different features of market structure play a significant role in pricing power of such microeconomic entities as farmers and grain enterprises in grain production and transaction. And the market structure determines welfare distribution model of consumers' surplus and producers' surplus at the market.

Tanulmányunkban azt vizsgáltuk, hogy az elmúlt 10 év adatai igazolják-e azt, hogy a kelet-európai országok csak az alultőkésítettség miatt nem teljesítettek a potenciáljuknak megfelelő mértékben. Az Európai Unió tagországai közül kiragadtunk 6 nyugati és 6 keleti országot, vagyis két országcsoportot képeztünk, ezt követően pedig megvizsgáltuk a kiválasztott 6-6 ország teljesítményét.  Megállapítható, hogy az elmúlt évtizedben a keleti térség országainak kibocsátási szintje a potenciális pálya közelében mozgott, miközben a hat nyugati ország teljesítménye észrevehetően elmaradt saját potenciális értékétől.

Exploring the role of fertilizer application on the sustainability of Greek potato farms: A DEA application
Provedor de dados: 31
Autores: Vasileiou,   Konstantinos Z.
Farm sustainability is becoming an increasingly important issue to European agriculture. However, fertilizer leaching to groundwater is still a major concern for Greek agriculture. The impact on the maximum potential short-run profit and yield, when fertiliser application dose is limited to certain point, was examined, using Data Envelopment Analysis (DEA). Spring potato farmers were found to apply rather high doses of chemical fertiliser, which poses high potential risk for nitrate and phosphorus leaching to groundwater. However, restricting nitrogen application to the doses recommended by agronomists would imply only little economic and yield sacrifices on potato farms,but resulting to significant reduction to potential environmental risk.

Tajikistan is classified by the World Bank as one of the CIS countries that are most vulnerable to climate change risks. This paper provides a closer look at a set of variables that determine Tajikistan’s vulnerability to risk in general and to climate change risk in particular. After presenting some background information on Tajikistan (Chapter 1), we provide a conceptual introduction to vulnerability and discuss some quantitative approaches to vulnerability assessment that have been recently applied in the literature (Chapters 2-4). We then use official statistical data for Tajikistan to assess quantitatively a range of basic variables that are recognized in the literature as determinants or drivers of vulnerability (Chapter 5). These variables include...

Measures of Farm Household Well-Being Tell Different Stories
Provedor de dados: 31
Autores: Jones,   Carol Adaire; Milkove,   Daniel.
Traditionally, the economic well-being of households is gauged by indicators of the financial resources available–— household income and, when available, wealth. ERS publishes estimates of farm household income and wealth based on responses to USDA’s annual Agricultural Resource Management Survey (ARMS). Since 1998, average farm operator household income has exceeded that of the typical U.S. household by 3 to 21 percent, and median farm household wealth has been 4-5 times that of all U.S. households. But the variability of income complicates farm-nonfarm comparisons.

During the 2007-09 recession, inflation-adjusted food expenditures by U.S. households fell 5 percent—the largest decrease in at least 25 years. Spending patterns differed by income level, with middle-income households curbing expenditures the most. Households responded to the recession by cutting back on eating out and by economizing on grocery purchases.

The Supplemental Nutrition Assistance Program, Financial Stress, and Childhood Obesity
Provedor de dados: 31
Autores: Burgstahler,   Rebecca; Gundersen,   Craig; Garasky,   Steven B.
The Supplemental Nutrition Assistance Program (SNAP) is the largest nutritional assistance program addressing food insecurity in the United States. Due to the program’s reach, SNAP has been called upon to address other nutrition-related challenges facing low-income Americans, including childhood obesity. This study considers the effect of SNAP participation on child weight outcomes after controlling for household financial stress, an important determinant of child overweight status that disproportionately affects low-income households. Using data from the Survey of Household Finances and Childhood Obesity and instrumental variable methods, we find that SNAP participation is negatively associated with obesity among eligible children.

Autores: Huang,   Jikun; Hu,   Ruifa; Rozelle,   Scott; Qiao,   Fangbin; Pray,   Carl E.
Genetically modified cotton varieties have greater production efficiency for smallholders in farming communities in China. We also find that the adoption of Bacillus thuringiensis (Bt) cotton varieties leads to a significant decrease in the use of pesticides. Hence, we demonstrate that Bt cotton appears to be an agricultural technology that improves both production efficiency and the environment. In terms of policies, our findings suggest that the government should investigate whether or not they should make additional investments to spread Bt to other cotton regions and to other crops.

The Doha Round and Food Security in the Dairy Sector in Cameroon: A Global Simulation Model (GSIM) Approach
Provedor de dados: 31
Autores: Leudjou,   Roland R.
In the framework of the new round of trade liberalization launched in Doha, paragraph 13 of the Development Declaration states that members will support special and differential treatment to accommodate development, including food security. This article simulates scenarios of multilateral tariff reduction from the WTO December 2008 draft modalities on agriculture for the Cameroon dairy sector. Using the Global Simulation Model, the analysis shows a substantial increase in world and domestic consumer prices, as the reduction of bound tariffs does not affect the applied tariffs given the high "binding overhang". As a consequence, consumers' welfare decreases.

Diversification choices in agriculture: a Choice Modelling case study of sugarcane growers
Provedor de dados: 31
Autores: Windle,   Jill; Rolfe,   John.
Growers in the sugarcane industry have been struggling under financial pressure for several years. One option to improve farm viability might be to diversify farm enterprise income. Choice Modelling, an economic valuation technique, was used to explore the trade-offs growers make between different attributes of diversification, and how their choices may be related to certain socio-economic characteristics. Application of the technique involved surveys of cane growers in three regions of Central Queensland. This is a novel approach to assessing grower intentions that has the potential to reveal detailed information about influences on grower choices.

Managing staple length in fine-wool sheep using shearing interval

Autores: Lee,   Greg J.; Sladek,   Mary Ann; Cox,   Rodney J.; Gordon,   Rachel V.; Johnson,   Sue.
Anecdotal evidence, confirmed by an analysis of six years wool sales data, indicates that selection to reduce fibre diameter and maintain, or increase, fleece weight, has led to an increase in the quantity and staple strength of fleeces produced. Long staples attract a price penalty. However, a comparison of 9- vs. 12-monthly shearing indicated that reducing the shearing interval to 9 months did not lead to any significant improvement in gross margins. An analysis of the effects of age and growth period on the repeatability of staple length indicated that sheep with the potential for long staple lengths could be allocated to appropriate management groups at 9 or 12 months-of-age.

The present paper has analyzed the mechanism by which farmers try to cope with the supply-demand gap of agricultural labourers during busy agricultural seasons in the face of growing shortage of agricultural labourers. The traditional mechanism of patron-client relationship between farmers and agricultural labourers has been dealt with in this regard. In this paper an attempt has been made to find answer to the following questions: What is the degree of attachment of the agricultural labourers with the employer? Is there any patron-client relationship between the employer and the employee? How effective is this relationship as a coping mechanism to mitigate the problem of supply-demand gap of agricultural labourers? The paper is based on a micro level...

This study explores the potential for risk reduction by New Zealand farmers through the diversification of their farm asset portfolios to include financial investments such as ordinary industrial shares, government bonds and bank bills. Low correlations between rates of return on farm and these financial assets suggest that significant reduction of income variability might follow their inclusion in farmers’ portfolios. Stochastic efficiency analysis is used to analyse alternative portfolios of ordinary shares, government bonds and bank bills and New Zealand farmland, using coefficients of absolute risk aversion derived from a negative exponential utility function. The results suggest that those farmers showing high degrees of risk aversion would gain...

Regional economic impacts of a plant disease incursion using a general equilibrium approach
Provedor de dados: 31
Autores: Wittwer,   Glyn; McKirdy,   Simon; Wilson,   Ryan.
The present study uses a dynamic multiregional computable general equilibrium (CGE) model to estimate the micro- andmacroeconomic effects of a hypothetical disease or pest outbreak. Our example is a Karnal bunt incursion in wheat in Western Australia. The extent of the incursion, the impact of the disease or pest on plant yields, the response of buyers, the costs of eradication and the time path of the scenario contribute to outcomes at the industry, regional, state and national levels. We decompose the contribution of these individual direct effects to the overall impact of the incursion. This might provide some guidance regarding areas for priority in attempting to eradicate or minimise the impacts of a disease or pest. The study also introduces a theory...

Continuous improvement and continuous innovation are used in the service and manufacturing industries, but there is little evidence of their use in the beef production sector. This paper examines the evidence relating to Continuous Innovation and Continuous Improvement and describes a collaborative partnership approach to its implementation in the beef industry. The results indicate that using a facilitated network of businesses can increase the uptake of innovations and improvements in beef businesses. Results also indicate that there is a need to develop facilitators so that they are aware of the impact of innovations and improvements on business profitability and so they can assist managers and business owners to implement short term changes to the...

Kutatásunk célja fényt deríteni arra, hogy a vállalkozások környezeti teljesítménye befolyásolja-e pénzügyi teljesítményüket, továbbá az, hogy milyen szerepet játszik ebben a média, hogyan változott az elmúlt időszakban a vállalkozások zöld erőfeszítéseinek megítélése? Megállapítható, hogy azokban a vállalkozásokban, amelyekben a média és a befektetők környezeti teljesítményüket kedvezően ítélik meg, magasabbak a megtérülési (ROE) mutatók, mint azokban, amelyeknek környezeti teljesítményét nem ítélik meg pozitívan. A magyarországi társadalomban a nem anyagi értékek iránti érzékenység és a környezettudatosság alacsony szintű. A társadalmi értékrendben alárendelt szerepet játszó környezetvédelmi gondolkozásra – reklámérték híján – a média mérsékelten hat. Ez...

The Effects of NAFTA and U.S. Farm Policies on Illegal Immigration and Agricultural Trade
Provedor de dados: 31
Autores: Luckstead,   Jeff; Devadoss,   Stephen; Rodriguez,   Abelardo.
We analyze the effects of the North American Free Trade Agreement (NAFTA) and United States farm subsidies on U.S.-Mexican illegal immigration and agricultural trade. The theoretical analysis develops an integrated trade-migration model and shows that NAFTA and U.S. subsidies exacerbate the illegal labor flow and increase U.S. exports. The theoretical analysis is empirically implemented by simultaneous estimation and simulation analysis. The analysis shows that NAFTA increased the number of undocumented workers to U.S. agriculture and U.S. farm exports to Mexico by an average of 1573 and $6.82 billion, respectively. U.S. farm subsidy reduction decreases unauthorized entry marginally and U.S. farm exports by an average of $3.2 billion.

Autores: Nunn,   Mike J.
Australia’s very good animal health status faces a wide range of biosecurity challenges that will arise during the next decade from changes in disease risk, ecosystems, technology and the policy environment in which animal producers operate. An understanding of these challenges should help enable producers to adopt management strategies to make their enterprises more resilient, as well as help policy-makers make better-informed choices to maintain and improve the health of Australia’s animals and animal industries.

Currently almost all energy is provided by fossil fuels that increase greenhouse gas emissions contributing to global warming. These emissions can be reduced with the use of renewable energy produced from biomass such a livestock manure. The manure is raw material for production of electricity and thermal energy. Anaerobic digestion of waste can reduce emissions by capturing methane, a greenhouse gas produced by waste in facilities large and small scale. The South Central region of the state of Chihuahua has the potential for renewable energy production from biomass and waste are approximately 58,000 head of cattle, valuing a daily output of 2,900 m3 of sewage and 10,000 m3 of waste water can cause environmental problems.

The aged care industry in regional Australia: will it cope with the tsunami to come?

Autores: Sappey,   Jennifer; Bone,   Zelma.
This paper reports on a pilot project to map the aged care industry in the Bathurst region of Central West New South Wales. The purpose of the project is to inform the future efforts of government, community based providers (CBPs) and private agencies in the sustainable development of the aged care industry. Early data suggest that the fragmented industry structure of CBPs, funded through asynchronous, disjointed state and federal funding programs, will be unable to respond to the increased demand for aged care services during the next decade. Initial findings also suggest that market tensions between CBPs and commercial providers will increase as they engage in competitive tendering for federal and state funding, and directly compete for scarce labour in...

Consumer Market for Functional Foods in South Brazil
Provedor de dados: 31
Autores: de Barcellos,   Marcia Dutra; Lionello,   Rafael Laitano.
This study aims at investigating the consumer market for functional foods (FF) in Porto Alegre, South Brazil. Functional food is any healthy food claimed to have a health-promoting or disease-preventing property beyond the basic function of supplying nutrients. Health has been named as the most significant trend and innovation driver in the global food and drinks market. Brazil is one of the leading countries in food production and consumption, and the market for functional foods have been growing 10% per year, three times more than the market for conventional foods. Although this food category is considered mature in some developed markets (such as in Japan, in the Nordic countries and in the U.S), it is still unknown for many consumers, especially those...

Quality Choices in a Vertical Structure: National Brands vs Private Labels in Grocery Retailing
Provedor de dados: 31
Autores: Fousekis,   Panos.
The paper analyzes quality choices in a vertical structure involving a monopolist food manufacturer (national brand-NB producer) and a monopolist retailer supplying both the national brand as well as a private label (PL). The analysis is based on a threestage dynamic game. According to the results, in the Nash equilibrium the two players choose the maximum possible qualities for their products. This means that the B food manufacturer seeks the maximum product differentiation, while the LP retailer seeks the minimum product differentiation. The behavior of the two players appears to be consistent with actual developments in the food markets as well as with earlier empirical studies documenting the efforts of NB food manufacturers to increase product...

Water flow risks and stakeholder impacts on the choice of a dam site
Provedor de dados: 31
Autores: Bicak,   Hasan Ali; Jenkins,   Glenn P.; Ozdemirag,   Ali.
This study evaluates three alternative locations for building a fresh water dam in the Yeşilirmak Valley of North Cyprus. Each of the three sites has different investment costs, water storage capabilities and socio‐political repercussions. These kinds of trade‐offs have in recent years characterised much of the worldwide debate surrounding the construction of electricity and irrigation dams. Another issue raised in this paper is the appropriate treatment of the risk and variability associated with the availability of water to fill the dam through time. This paper demonstrates how an integrated financial‐economic‐stakeholder analysis can provide the inputs needed by decision‐makers in such situations to make rational political and economic choices.

Farms and farming are major contributors to the world economy, directly responsible for a large part of GDP. These achievements are not trivial and imply that farms are being managed in reasonably effective ways, else agricultural industries would not be sustained. However has the study of Farm Management within Australia made significant contributions to agriculture or lagged in the background. Is it contributing to better Farm Management or merely cataloguing what has happened? Is it leading or following? During recent years there has been an increasing interest in managing farms more sustainably, with emphasis on issues beyond short-term profitability to encompassing rural communities, ecosystems, biodiversity, ethics of technology and politics.

Rural Europe 2+2+: A conceptual framework for a rural employment policy
Provedor de dados: 31
Autores: Fieldsend,   Andrew F.
The four main ways in which rural employment creation can be grounded on the exploitation of natural capital can be structured by two complementary analytical directions.  These are firstly, ‘production’ based on (a) renewable resources (agriculture, energy) and (b) depletive resources (energy, construction materials) and, secondly, ‘consumption’ by (a) non-residents (tourism and leisure) and (b) residents (incomers including the wealthy retired).  This analysis forms the basis of a conceptual framework (Rural Europe 2+2+) which recognises that there is no simple definition of rural employment but that a sustainable approach to exploiting natural capital, together with the development of the other capitals of the territory via a place-based (i.e....

Private sector investment in agricultural research and development in Australia
Provedor de dados: 31
Autores: Keogh,   Mick.
There is growing recognition that the private sector is playing an increasingly important role in agricultural research and development internationally, and in Australia. There are only very limited data available about the extent of private sector research and development (R&amp;D) investment that is occurring in Australia, and the nature of that investment. This paper reports the results of a survey and data review that was carried out to gain a better understanding of private sector agricultural R&amp;D investment in Australia. The survey, whilst limited, suggests that private sector agricultural R&amp;D investment in Australia is more significant than previously reported, and that private sector investors see public sector investment in this area as...

Taxes and quality: A market-level analysis
Provedor de dados: 31
Autores: James,   Jennifer S.; Alston,   Julian M.
Aconventional assumption of product homogeneity when the commodity of interest is actually heterogeneous will lead to errors in an analysis of the incidence of policies, such as taxes. In this article, an equilibrium displacement model is used to derive analytical solutions for price, quantity, and quality effects of ad valorem and per unit taxes. The results show how parameters determine the effects of tax policies on quality. The potential for tax-induced distortions in quality, and the distributive consequences of those distortions, are illustrated in a case study of the market for Australian wine.

Rural America Benefits From Expanded Use of the Federal Tax Code for Income Support
Provedor de dados: 31
Autores: Farrigan,   Tracey L.; Durst,   Ron L.
Over the past two decades, the Federal tax code increasingly has been used as a tool for achieving social and other policy objectives, primarily through the expanded use of tax credits. A larger share of rural taxpayers benefit from Federal tax policies aimed at lower income taxpayers because they have historically had lower incomes and higher poverty rates than urban households. The earned income and child tax credits have provided a substantial boost in income to low and middle-income rural taxpayers and have reduced the rural poverty rate.

The present paper surveys various methods used to analyse market power in the retail food industry. The strengths and weaknesses of these approaches are explored and a review of the issues in using New Empirical Industrial Organization (NEIO) and time-series models is provided. The absence of a theory underlying time-series models is highlighted and a review of some theoretical models in retailing is presented. The impact of imperfect competition in the food processing sector on retailing is also examined. It is argued that a combination of the approaches that minimises the weaknesses and builds on the strengths of single approaches may prove more promising for examining non-competitive behaviour.

Economic analysis of automatic flood irrigation for dairy farms in northern Victoria
Provedor de dados: 31
Autores: Armstrong,   Dan P.; Ho,   Christie K.M.
Interest in automatic flood irrigation is strong, given the labour and lifestyle benefits it can provide. An economic analysis of three automated flood irrigation systems for a dairy farm in northern Victorian indicated that automatic irrigation can be a profitable labour saving investment in many cases. However, profitability was sensitive to the amount and value of the labour saved. Pneumatic and timer systems were good investments regardless of the area they were installed to service. The supervisory control and data acquisition (SCADA) system was a good investment when more than 50 ha were serviced by the system. Irrigation water savings are unlikely to have a significant effect on the profitability of automatic irrigation, particularly if the price of...

Autores: Doole,   Graeme J.
Lucerne ( Medicago sativa L.) helps to prevent soil salinisation in the Western Australian Wheatbelt by reducing recharge to saline water tables. There is broad consensus, though, that it is not sufficiently profitable to motivate producers to plant it at the intensity at which considerable off-site benefits would be conferred. This paper employs a multiple-phase optimal control model to explore the value of this perennial pasture for the management of herbicide-resistant annual ryegrass ( Lolium rigidum Gaud.) in a crop–pasture rotation, given the difficulty of observing this value in practice. The availability of selective herbicides for efficient weed control is found to determine whether or not it is profitable to adopt lucerne pasture under optimal...

Autores: Mason,   Jane; Blackwood,   I.
The Animal Welfare Sub-Unit of the NSW Department of Industry and Investment, in association with some members of the Extensive Livestock Industry and Development (ELID) sheep and beef team, have been developing procedures and training to help District Livestock Officers (DLOs) deal with RSPCA cases involving failure to provide animals with food. These procedures are being developed to ensure evidence collected will withstand a courtroom cross-examination. The resources developed will be extended to staff of various organisations involved in animal welfare cases with livestock. Several areas have been identified for future research that will improve these procedures.

Farm Management analysis: a core discipline, simple sums, sophisticated thinking
Provedor de dados: 31
Autores: Malcolm,   Bill.
In this paper it is argued that solving problems in farm management involves applying an appropriate balance of disciplinary knowledge. More specifically, farm management decision-making is about making choices, and the discipline of choice is economics. Thus economics is the core discipline of farm management analysis and decision-making. Modelling farm systems using the whole farm approach, with emphasis on the risky elements, can be very useful. Also enlightening is using real farm case studies to test research output. The conclusion is that bringing to bear on farm management questions a few disciplines, a few perspectives and a few figurings to explore a few futures is a useful way to go.

The study has identified the factors responsible for rural-urban migration based on 120 sample respondents each of migrants and non-migrants spread over two districts, viz. Ratnagiri and Sindhudurg of Konkan region of Maharashtra by employing the logit model. The study has highlighted the importance of rural development programs like MGNREGA that are being implemented by the government with a view to provide employment and income to the rural population in the country. It has also shown that for both migrant and non-migrant households,, agriculture was the major source of income, and their consumption expenditure was more than the production expenditure. It has also been observed that migration has a positive impact on income, expenditure and net savings...

Changes in cereal land use and production level in the European Union during the period 1999-2009, focusing on New Member States
Provedor de dados: 31
Autores: Takacs-Gyorgy,   Katalin; Takacs,   Istvan.
The decrease in the area of arable land has further continued in the European Union (EU) since the Millennium. Sustainable development is partially based on the sustainable use of natural resources, which is based on the limitation of land use and on the introduction of different incentives. Previous direct subsidies resulted in increased production. The reform of the Common Agricultural Policy (CAP) has aimed to stop the increase in production, possibly even to decrease production. The objective of this research is to show whether such an effect on land use and on the change of production structure in the EU can be observed. Analyses have shown that agricultural and arable areas have further decreased within land use since the Millennium, continuing the...

Use of strategies and decision rules by Australian wool producers to manage uncertainty
Provedor de dados: 31
Autores: Murray-Prior,   Roy B.; Wright,   Vic.
Decisions by Australian wool producers were modelled with a technique combining personal construct psychology and hierarchical decision models. Both strategic and tactical approaches were evident in wool producers’ responses to the risks associated with producing and marketing their wool. Strategic responses included avoiding short to medium-term response to price changes, diversification, maintaining equity and selling wool at auction in the same sale each year. Producers identified many types of risk, with each engendering a distinctive response. Similarly the context of a decision appeared to have a major influence on the attitude to risk. Simplifying decision rules were apparent that helped producers deal with the physical, information, and processing...

Összességében megállapítható, hogy Magyarországon az elmúlt fél évszázadban rendkívül megnőtt az energiafelhasználás, ami többnyire a fosszilis tüzelőanyagokból nyert energiára alapult. Ez arra készteti a jelen és a jövő kor társadalmát, hogy törekedjen a rendelkezésre álló megújuló energiaforrások felhasználásának előtérbe helyezésére, melyek használata a fenntarthatóság és a versenyképesség szempontjából sem elhanyagolható, hiszen ismert, hogy napjaink egyik kritikus költségtényezőjét adják az energiaköltségek. A megoldásban jelentős szerep hárul a vidéki társadalmakra, mert hiába történik az energiafelhasználás zöme az urbanizált területeken, az energia-előállítás, kitermelés a vidékre koncentrálódik.

Understanding Ornamental Plant Market Shares to Rewholesaler, Retailer, and Landscaper Channels
Provedor de dados: 31
Autores: Hinson,   Roger A.; Paudel,   Krishna P.; Velastegui,   Marco.
Market channel alternatives that include garden centers, landscapers, mass merchandisers, and rewholesalers have contributed to the growth of ornamental crops sales in the United States. The impact of growers’ business characteristics on shares of sales to these channels by firm size was estimated using the two-limit Tobit model. Important explanatory variables were regions of the United States, sales of plant groups, kinds of contract sales, and channel diversity. There were important differences in behavior by grower size. Overall, the results indicate a stronger than expected role for the rewholesaler channel as a preferred channel for ornamental plant sales.

Despite the modest regional consumption of organic products, Sicily is one of the most important European regions in surface area per number of companies active in organic farming. The University of Palermo, as early as 2000, to promote the development and success in this industry, the Faculty of Agriculture, introduced two major degree programs in "Organic Farming". The objective of these courses is to train graduates who are technically capable of supporting the organic farmers market, to promote and facilitate the expansion of the consumption of organic products, and to create employment opportunities for young graduates. At the end of 2009, in the area of these activities, a training and research program involved numerous students in the creation of an...

Autores: Zhao,   Huan; Liu,   Jian-qiu; Qu,   Kai-yue; Feng,   Li; He,   Yi.
In recent years, the price of traditional Chinese medicinal materials soars continuously, and the resulting price risk increasingly looms large, which has critically affected midstream and downstream industries and peoples' demand for drug, and imperiled healthy and orderly development of traditional Chinese medicinal industries. Based on the status quo of continuous skyrocketing price of traditional Chinese medicinal materials at present, we winkle out the root cause of soaring price as follows: the supply and demand lose balance; the production costs hike up; there are other factors responsible for soaring price. This paper further analyses the impact of sharp increase in price of traditional Chinese medicinal materials on ail links of industry chain as...

ERS research shows that away-from-home meals and snacks tend to contain more calories and to be of lower nutritional quality than food prepared at home. Recent legislation will require chain restaurants across the United States to list calorie information on their menus and menu boards. Calorie disclosure may prompt consumers to substitute menu items that lower their caloric intakes and may encourage restaurants to offer lower calorie options.

Saltbush – a case for reintroduction
Provedor de dados: 31
Autores: Ledger,   Peter; Morgan,   Christopher K.
This paper reviews historical, philosophical and socio-cultural information as a means of explaining why saltbush in Australia has declined. That decline coincided with introduced hard hoofed animals overgrazing native pastures and was compounded by land clearing. Over time, losing ecosystem diversity degraded vegetation, soil and water resources; subsequently, watertables rose. A benefit of saltbush ecosystems has been keeping landscape function stable by controlling saline watertables. In suitable ecosystems, the reintroduction of saltbush would be potentially highly rewarding, but significant impediments block the way, none more so than a decision-making context overwhelmingly constrained by short-term production and financial considerations.

The economies of developed countries have, since 2007, experienced the most significant and persistent period of economic malaise since the 1930s. Domestic economic policies have failed to revive sustained economic growth and, as a result, unemployment remains at levels that voters find difficult to accept. In addition, without tax revenue-enhancing growth, government deficits persist, and borrowing to finance the cumulative deficits has become increasingly difficult for some countries. With domestic policies largely exhausted, but economic growth elusive, policy makers have been considering external policies as a means to stimulate their economies. Trade protectionism and strategic devaluation are potential policies. The lessons of the 1930s regarding the...

Survey on the Peasants' Will of Forest Land Transfer in the Reform of Collective Forest Right System - On the Case of 180 Peasant Households in Lishui City of Zhejiang Province
Provedor de dados: 31
Autores: Li,   Zhi.
Taking sample survey in the eighteen villages of Yunhe, Longquan and Qingyuan County of Lishui City of Zhejiang Province, the results show that the forest land transfer of sample peasants is mainly transfer-out. The private treaty of forest land transfer is the main pattern of most peasant households, forest right trading market hasn't got wide approval in peasants, peasants' dependence on land is reducing, and so on. Through analysis, the reasons of influent transfer of forest land include peasants’ subjective will, less type of transfer objects, dull information communication, big difference of expected price and imperfect development of intermediary organization. In order to promote a healthy development of forest land transfer, the paper puts forward...

Autores: Vittorini,   Pierpaolo; Necozione,   Stefano; di Orio,   Ferdinando.
The need for timely collection and analysis of epidemiological data is becoming of primary importance, e.g., for bioterrorism detection or epidemiological surveillance. Web-based information systems (WISs) may provide the needed technological support. Thus we present the WeeW (workflow-enabled epidemiological WIS) system—i.e., a WIS that helps epidemiologists, through workflow management, to effectively select remote centers, collect, and process the received data to produce conclusive technical reports. In detail, we show the functionalities of the WeeW system, its architecture, and particularly Stata’s role in executing statistical analyses and producing graphs. Furthermore, we discuss the performance of the WeeW–Stata interface. Finally, we outline...

The Trees and the Bees: Using Enforcement and Income Projects to Protect Forests and Rural Livelihoods Through Spatial Joint Production
Provedor de dados: 31
Autores: Albers,   Heidi J.; Robinson,   Elizabeth J.Z.
Forest managers in developing countries enforce extraction restrictions to limit forest degradation. In response, villagers may displace some of their extraction to other forests, which generates “leakage” of degradation. Managers also implement poverty alleviation projects to compensate for lost resource access or to induce conservation. We develop a model of spatial joint production of bees and fuelwood that is based on forest-compatible projects such as beekeeping in Thailand, Tanzania, and Mexico. We demonstrate that managers can better determine the amount and pattern of degradation by choosing the location of both enforcement and the forest-based activity.

Trade liberalisation and regional integration: the search for large numbers
Provedor de dados: 31
Autores: Robinson,   Sherman; Thierfelder,   Karen.
We surveyed the empirical literature using multi-country computable general equilibrium (CGE) models to analyse potential and actual regional trade agreements (RTAs). The studies indicate that these RTAs improve welfare, that trade creation greatly exceeds trade diversion, and that they are consistent with further global liberalisation. The welfare gains are bigger when models incorporate aspects of ‘‘new trade theory’’ such as increasing returns, imperfect competition, and links between trade liberalisation, total factor productivity growth, and capital accumulation. We also conjectured that an RTA expands market size and stability, allowing firms to pursue economies of fine specialisation, generating additional ‘‘Smithian’’ efficiency gains.

Autores: McRae,   Timothy B.; Cox,   Rodney J.; Watson,   Geoff K.
In this paper the results of a situation analysis of the Australian venison industry are presented from a study commissioned as part of the development process of an endorsed strategic plan for the Australian farmed venison industry. An extensive literature review, combined with in depth interviews with industry participants, revealed that the Australian venison industry is currently in an extended slump, characterised by a lack of viability within the industry. This lack of viability is due to many factors including, a decline in the number of large scale producers, reduced slaughter and production levels, historically low farm gate returns and very low demand for venison in the domestic market. A significant decline in export demand for venison has also...

Contribution of Wildlife to the Value of U.S. Southern Forestland
Provedor de dados: 31
Autores: Straka,   Thomas J.
Rural appraisers should be aware of the important contribution wildlife values and hunting leases make to forestland value. Many rural appraisals take place on small family holdings that constitute about 62 percent of private forestland in the United States. Roughly 12 percent of these small forest holdings are leased for hunting or some other recreational use, producing significant annual revenue. The methodology to value these contributions is described. Using southern hunting lease revenues and a six percent real discount rate, hunting leases increased forestland values by $184.00 per acre on average, certainly a significant contribution to value.

A comparison of fitness between horses with different exercise history
Provedor de dados: 31
Autores: Barker,   Anna B.E.; Warren-Smith,   A.K.
Anecdotal evidence suggests that a horse’s prior fitness level has an effect on the horse’s ability to return to that previous level of fitness. This trial aimed to test this assumption which would benefit horse trainers to create individual fitness programs for horses. Standardised exercise testing was used to compare the progress of two groups of horses during weeks three and seven of a 14-week training program. Group A had undergone a similar training program twelve months previously and Group B had not. Plasma lactate samples and heart rate monitoring were used to assess the levels of fitness of the horses. Analysis of variance showed that there was no significant difference in post-exercise plasma lactate concentration between the groups. The horses...

Evaluating the potential contribution of contract auctions to Agri-Environmental Policy efficiency: A simulation model for Emilia-Romagna (Italy)
Provedor de dados: 31
Autores: Viaggi,   Davide; Raggi,   Meri; Gallerani,   Vittorio.
Auctions are a potentially suitable policy tool for increasing the efficiency of Agri- Environmental Schemes (AES) through an improved allocation of contracts. In theory, through the auction mechanism, farmers have incentives to reveal their compliance costs, helping to reduce information rents and increase policy cost-effectiveness. The aim of this paper is to simulate the potential contribution of auction mechanisms to the efficiency of AES in Emilia-Romagna (Italy). The results show advantages for auctions compared with traditional flat rate payments based on average compliance costs. However, their performance is worse than flat payments based on marginal compliance costs.

Comparing the Cost-Effectiveness of Water Conservation Policies in a Depleting Aquifer: A Dynamic Analysis of the Kansas High Plains
Provedor de dados: 31
Autores: Ding,   Ya; Peterson,   Jeffrey M.
This research analyzes two groundwater conservation policies in the Kansas High Plains located within the Ogallala aquifer: 1) cost-share assistance to increase irrigation efficiency; and 2) incentive payments to convert irrigated crop production to dryland crop production. To compare the cost-effectiveness of these two policies, a dynamic model simulated a representative irrigator’s optimal technology choice, crop selection, and irrigation water use over time. The results suggest that the overall water-saving effectiveness can be improved when different policy tools are considered under different conditions. High prevailing crop prices greatly reduce irrigators’ incentive to give up irrigation and therefore cause low enrollment and ineffectiveness of the...

Rising pressure on sugar prices was intensified by supply disruptions in 2009, driving prices to double the long-term average. Higher production costs and growing ethanol use in Brazil set the stage for higher prices, but policy-induced production swings among Asian countries are the main source of price volatility in world markets. Although dramatic fluctuations in world prices have affected U.S. sugar prices, domestic sugar policy continues to drive U.S. sugar price movements.

Does Healthy Food Cost More in Poor Neighborhoods? An Analysis of Retail Food Cost and Spatial Competition
Provedor de dados: 31
Autores: Hatzenbuehler,   Patrick L.; Gillespie,   Jeffrey M.; O'Neil,   Carol E.
The organization of the Baton Rouge, Louisiana, retail food industry was analyzed to determine whether spatial competition influenced the cost and availability of food items. Using a spatial competition gravity variable, the costs of two separate market baskets were analyzed in January 2009, and the factors influencing spatial competition were determined. Store type (chain or supercenter) was found to be the most significant determinant of food costs, validating findings of past studies. Although food was not found to be more expensive in low-income areas, results suggest that residents in low-income and rural areas have disincentives to purchase affordable, available healthy food due to the spatial organization of their local food market.

A financial analysis of the impact of sheep on the risks and returns associated with mixed enterprise dryland farming in south-eastern Australia: Part II
Provedor de dados: 31
Autores: Hutchings,   Timothy R.
This paper extends the long-term cash-flow simulations reported in Part I (Hutchings 2009) to include a range of seasonal scenarios at four representative dryland sites in south-eastern Australia. The effect of varying the proportion of sheep and cropping in the enterprise mix at each site on cash surpluses is discussed. The analysis shows that, for most sites, the cropping enterprises require better than average seasons, prices and water-use efficiencies to generate a positive cash flow and are subject to substantial variability and risk of loss. In contrast, the sheep enterprises show small but stable cash flows in all but extreme drought conditions. This paper emphasises the need to include site-specific, long-term variability and whole-farm costs in...

Spatial Externalities of Pest Control Decisions in the California Citrus Industry
Provedor de dados: 31
Autores: Grogan,   Kelly A.; Goodhue,   Rachael E.
Predaceous and parasitic insects provide control of important citrus pests. However, many pesticides are toxic to these beneficials. Using California citrus grower survey data, this article tests whether landscape-level use of pesticides affects the presence of and reliance on Aphytis melinus, an important beneficial insect. Results show that landscape-level pesticide use decreases the presence of A. melinus and increases reliance on insecticides. Pesticide use on non-citrus crops has a significant negative effect on the presence of Aphytis melinus, suggesting a cross-crop spatial externality. Our findings illustrate that regulations designed to address cross-crop effects on beneficial insects can increase social welfare.

This paper aims at specifying the main determinants of the intra-industry trade in agricultural products, associated with the funds of the Common Agricultural Policy (CAP) of the EC, and more precisely, with its “price support mechanism” and its “structural reform policy.” It presents CAP’s reformed main tools and mechanisms, and explains the choice of selected variables as determinants of intra-industry trade in agricultural products at intra-EC trade. The econometric analysis covers the period 1973-2005, following recent developments in time-series analysis employing the ARDL approach to cointegration. The empirical results provide evidence of Granger causal effects in both on short-run and long-run horizon running from CAP’s above mentioned policy tools...

Valuing options for reserve water in the Fitzroy Basin
Provedor de dados: 31
Autores: Rolfe,   John; Windle,   Jill.
Option values may be an important component of non-use values when development options for environmental assets are considered. These are values that the community might hold for maintaining options to make future choices about allocating resources. However, option values are very difficult to define, at both theoretical and practical levels, and there has been a retreat over the past decade to the more inclusive concept of option prices. In the present paper, estimates of option values are reported for retaining unallocated water in reserve rather than using it for current development. The use of option values rather than option prices is justified on the basis that the focus is on nonuse values, and demand and supply uncertainties have been minimised....

This study investigates the potential for development of a regional environmental certification scheme through which beef producers in northeast Victoria, who were employing a high standard of environmental care, produced premium quality beef that could attract an improved financial return over regular market prices. Beef producers, butchers, domestic consumers and the restaurant industry were surveyed to identify the level of interest in the community for organic food and ‘clean and natural’ beef. Beef producers were further surveyed to identify their views on some elements of sustainable agricultural production. The findings conclude that there is a potential niche market for ‘clean and natural’ beef in Northeast Victoria. A certification scheme for...

Autores: Marchenko,   Yulia V.; Carroll,   Raymond J.; Lin,   Danyu Y.; Amos,   Christopher I.; Gutierrez,   Roberto G.
In the past decade, many statistical methods have been proposed for the analysis of case–control genetic data with an emphasis on haplotype-based disease association studies. Most of the methodology has concentrated on the estimation of genetic (haplotype) main effects. Most methods accounted for environmental and gene–environment interaction effects by using prospective-type analyses that may lead to biased estimates when used with case–control data. Several recent publications addressed the issue of retrospective sampling in the analysis of case–control genetic data in the presence of environmental factors by developing efficient semiparametric statistical methods.

Impacts of changing water price and availability on irrigated dairy farms in northern Victoria
Provedor de dados: 31
Autores: Ho,   Christie K.M.; Armstrong,   Dan P.; Doyle,   Peter T.; Malcolm,   Bill.
Farming systems throughout the Murray-Darling Basin are under increasing scrutiny from the perspective of ecological sustainability of farm and catchment systems. In northern Victoria, the dairy industry is a major user of water, and contributes to the environmental issues. Changes in irrigation water price, availability and policy will invariably impact on the viability of dairy farming in this region, but the diversity of dairy farm systems suggests that the impact will vary between farms. Two case study farms, a ‘water-reliant’ farm and a ‘fodder-reliant’ farm, were used to examine economic and social impacts of changes in water price, availability and policy.

Constraints or Cooperation? Determinants of Secondary Forest Cover Under Shifting Cultivation
Provedor de dados: 31
Autores: Klemick,   Heather.
This study examines the drivers of land use in a shifting cultivation system with forest fallow. Forest fallow provides on-farm soil quality benefits, local hydrological regulation, and global public goods. An optimal control model demonstrates that farmers have an incentive to fallow less than is socially optimal, though market failures limiting crop production can have a countervailing effect by encouraging fallow. An econometric model estimated using data from the Brazilian Amazon suggests that fallowing does not result from internalization of local fallow services but instead is associated with poor market access and labor and liquidity constraints.

Economic Analysis of Menthol Mint Cultivation in Uttar Pradesh: A Case Study of Barabanki District
Provedor de dados: 31
Autores: Kumar,   Sanjay; Suresh,   Ram; Singh,   Virendra; Singh,   A.K.
The present study has been carried out in the Barabanki district of Uttar Pradesh on economic analysis of menthol mint cultivation in the year 2010. The economics has been worked out by comparing costs and returns at different stages by the conventional method. The linear production function has been fitted to evaluate the resources-use efficiency in the production of menthol mint. The study has shown that the major portion of operational cost is shared by hired labour, interculture operations, distillation charges, irrigation and machine / tractor charge. The overall benefit-cost ratio has been found to be 2.55, which indicates a higher profit for farmers on less investment in mint cultivation. The independent variables like human labour, machinery,...

Autores: Nemeth-T.,   Anett; Vincze-Tóth,   Judit; Trojan,   Szabolcs.
A magyar hűtőipar számára a külföldi piacokon való értékesítés nagy jelentőségű. A hűtőipar talán az egyetlen ágazat, melynek termelése minőségileg sosem különült el az értékesítés piacai szerint, köszönhetően annak, hogy a vertikumban a nemzetközi követelmények érvényesültek. A komplex vásárlói modellek elemzését követően megállapítható, hogy az ízesített termékeket leginkább az aktív szellemi foglalkozásúak részesítik előnyben, akik átlag feletti jövedelemmel rendelkeznek. Az ízesített termékek és a vegyes összetevőjű (mix) termékek tipikus vásárlója között nem tapasztalható jelentős eltérés. A vizsgálat eredményei alapján az a következtetés vonható le, hogy az egy összetevőjű termékek vásárlói között a legalacsonyabb a férfiak és a legmagasabb a nők,...

Így kapott kiemelt figyelmet a vidéki turizmus, a kézműipar, a hungarikumok kérdése, jelenleg pedig a közvetlen termelői értékesítés lehetősége. Ezek közös jellemzője, hogy a kialakult állapotokat nem kérdőjelezik meg, csak annak életképességének javításához egy eddig is ismert megoldást tolnak előtérbe, elkerülve ezzel, hogy az alapvető gondokkal szembenézzenek.

Japanese Consumers’ Valuation of U.S. Beef and Pork Products after the Beef Trade Ban
Provedor de dados: 31
Autores: Peterson,   Hikaru Hanawa; Burbidge,   Linda D.
Analysis of survey data indicates that Japanese consumers discount their willingness to pay for U.S. beef and pork relative to that of domestic products, but that the discounts have declined from 2006 to 2009. The discounts for U.S. products were greater than those imported from other countries in 2006, but the 2009 discounts were statistically indistinguishable across origins. Our findings also suggest than Japan is a receptive market for meat produced with GM-free feed and for meat products meeting full organic standards.

Early indicators of the extent of climate change on Australian farms
Provedor de dados: 31
Autores: Crean,   Jason; Parton,   Kevin A.; Hayman,   Peter; Mullen,   John D.
More research is needed before we know the implications of climate change for Australian farms. Nevertheless given the information at hand, an assessment can be made of some early indicators. First, the severity of the recent drought was compared with earlier droughts. Second, the trend in rainfall was examined. Third, projections of climate change were reviewed to assess the likely course of climate variability, and hence provide a picture of the severity of future droughts. Although further research is warranted, the indications are that even if rainfall is no lower in future droughts, they may seem more severe because rising temperatures will tend to increase evaporation and reduce runoff.

Causes and Consequences of Supply-Demand Gap for Labour in Sugarcane in India
Provedor de dados: 31
Autores: Sharma,   Ashwani K.; Prakash,   Brahm.
The paper has estimated the demand for human labour use in sugarcane and other competing crops and changes over time in its use in major cane-growing states. It has also examined the supply-demand gap in human labour for sugarcane and has provided some coping strategies. The study, based on the primary as well as secondary data on the use of human labour for sugarcane for the past 30 years (1980 to 2010), has found that sugarcane cultivation is least mechanized and most labour-intensive in almost all major canegrowing states of India. The labour-use per hectare has increased in all the cane-growing states, except Tamil Nadu and Maharashtra. Study has revealed that the proportion of casual labour has increased over the years in sub-tropical states because...

A closer examination of subpopulation analysis of complex–sample survey data
Provedor de dados: 31
Autores: West,   Brady T.; Berglund,   Patricia; Heeringa,   Steven G.
In recent years, general-purpose statistical software packages have incorporated new procedures that feature several useful options for design-based analysis of complex-sample survey data. A common and frequently desired technique for analysis of survey data in practice is the restriction of estimation to a subpopulation of interest. These subpopulations are often referred to interchangeably in a variety of fields as subclasses, subgroups, and domains. In this article, we consider two approaches that analysts of complex-sample survey data can follow when analyzing subpopulations; we also consider the implications of each approach for estimation and inference. We then present examples of both approaches, using selected procedures in Stata to analyze data...

The value chain is a new concept inside the agricultural development in Mexico that involves having in mind the demands of the consumers for the development of commercialization strategies for fruits. The nutritional and functional properties can add value to food. The mango and byproducts generated during its processing or marketing are a very important source of bioactive compounds with high added value, mostly dietary fiber, micronutrients, polyphenols, carotenoids, among many others. These can be valorisated through multidisciplinary research, innovation, technology transfer, development of market studies and business plans, as well as the accompaniment during the management and implementation of functional foods in agro-business.

Rasch analysis: Estimation and tests with raschtest
Provedor de dados: 31
Autores: Hardouin,   Jean-Benoit.
Analyzing latent variables is becoming more and more important in several fields, such as clinical research, psychology, educational sciences, ecology, and epidemiology. The item response theory allows analyzing latent variables measured by questionnaires of items with binary or ordinal responses. The Rasch model is the best known model of this theory for binary responses. Although one can estimate the parameters of the Rasch model with the clogit or xtlogit command (or with the unofficial gllamm command), these commands require special data preparation. The proposed raschtest command easily allows estimating the parameters of the Rasch model and fitting the resulting model.

Autores: Kaminski,   Jonathan.
This paper provides new evidence on the pattern of individual subjective welfare after a natural experiment in policy-led rural development, and aims to identify the causal relationships between subjective welfare and political opinions on the effects of the policy change. I adopt a structural approach by introducing a reference-based utility function that contains a signal of individual participation in the policy change, which is conveyed by political opinions. Using data collected in cotton areas of Burkina Faso, several simultaneous estimations are performed to analyze seemingly covariant political opinions on the recent cotton reform and changes in subjective wealth, while addressing measurement issues related to subjective indicators as well as...

Productivity growth and the returns from public investment in R&amp;D in Australian broadacre agriculture
Provedor de dados: 31
Autores: Mullen,   John D.
Investment in R&amp;D has long been regarded as an important source of productivity growth in Australian agriculture. Perhaps because research lags are long, current investment in R&amp;D is monitored closely. Investment in R&amp;D has been flat while productivity growth has remained strong, relative both to other sectors of the Australian economy and to the agricultural sectors of other countries. Such productivity growth, at a time when the decline in terms of trade facing Australian farmers has slowed, may have enhanced the competitiveness of Australian agriculture. The econometric results presented here suggest no evidence of a decline in the returns from research from the 15 to 40 per cent per annum range estimated by Mullen and Cox. In fact the...

Household Production and the Demand for Food and Other Inputs: U.S. Evidence
Provedor de dados: 31
Autores: Huffman,   Wallace E.
The paper develops a new productive household model and a consistent household fullincome/ expenditure demand system for inputs and leisure of U.S. households. The demand system is fitted to U.S. annual aggregate data over the last half of the 20th century and findings include that the price and income elasticity of demand for food-at-home are roughly two times larger than for food-away-from-home and that food-at-home and away-from-home are substitutes. The price and income elasticity of demand for men’s unpaid housework are twice as large as for women’s unpaid housework and women’s and men’s unpaid housework are shown to be complements.

Potential Economic Impacts of the Managed Haying and Grazing Provision of the Conservation Reserve Program
Provedor de dados: 31
Autores: Campiche,   Jody L.; Dicks,   Michael R.; Shideler,   David W.; Dickson,   Amanda.
The Food Security and Rural Investment Act of 2002 included a new provision that allowed managed haying and grazing (including the harvest of biomass), if consistent with the conservation of soil, water quality, and wildlife habitat, in return for partial reductions in the annual CRP payments. The legislation provided for managed (or limited use) haying and grazing on the CRP acreage rather than prohibiting all use. This research analyzed whether or not the alternative grazing and haying scenarios would dramatically impact the price of beef or hay, and we estimated the impact such changes would have on state economies.

Empirical investigation of investment behaviour in Australia's pastoral region
Provedor de dados: 31
Autores: Agbola,   Frank W.; Harrison,   Stephen R.
Optimal intertemporal investment behaviour ofAustralian pastoralists is modelled using panel data for the period 1979–1993.Results indicate that quasi-fixity of inputs of labour, capital, sheep numbers and cattle numbers is characteristic of production in the pastoral region. It takes about two years for labour, four years for capital and a little over two years for both sheep numbers and cattle numbers to adjust towards long-run optimal levels. Results also indicate that, after accounting for adjustment costs, own-price product supply and input demand responses are inelastic in both the short and long run.

This paper presents an evaluation of a farm-business assessment model that uses financial performance measures and tracks ‘wealth change’ to evaluate performance trends over time, and ranks the relative business performance of commercial participants. Its core component involves the use of comparative analysis, which is structured as an introductory rapid-assessment model, together with a ranking system that has been designed to differentiate the relative performance levels of farm businesses. The system has been labelled as the Business Performance Index (BPI) model to reflect its performance-ranking role that explores the relationships, if any, between farmer attitudes and business performance. The BPI model is discussed within the context of the debate...

Research on the Model of Household Credit Risk Evaluation of Rural Microfinance
Provedor de dados: 31
Autores: Zhu,   Manhong; Si,   Chuan-yu; Wang,   Jing.
Since rural microfinance is a credit which grants loans without collateral and guarantees to farmers, it is considerably important to evaluate and control the household credit risk. Through establishing the evaluation index system and then using catastrophe progression theory, three common types of catastrophe system and the normalization formula, we get the comprehensive evaluation. Finally, we take the empirical test and the result shows that this method is simpler and more objective which can be used by the credit cooperatives to decide whether to authorize the loans.

The aim of this research was to determine the effects of different factors of production (farm management strategy, veterinary management, physical farm conditions, and breeding technology) on the performance of Hungarian pig breeding farms. Performance is defined in a broad sense, reflecting the complexity of pig breeding, taking into consideration technological and economic indices. According to our hypothesis a direct, quantifiable stochastic relation can be shown between management strategy, veterinary practice management, construction and building engineering characteristics of plants, breeding technology and the performance of farms. The data for the analysis were acquired by a direct question survey of more than 130 Hungarian pig breeding farms....

COMPETITIVIDAD DE LA CADENA ARROCERA DEL ESTADO PORTUGUESA, VENEZUELA, EN LOS PROCESOS DE INTEGRACIÓN EN SUDAMÉRICA
Provedor de dados: 31
Autores: Vivas,   Víctor; Albisu,   Luis Miguel.
The rice chain in the Portuguesa state is of great significance for Venezuela because half of the country's production comes from that state. Activities' integration that goes from production to consumption have some specificities which, in rice producing countries, the most important are those linked to the production and transformation of raw materials. On top, political and economic instability induce to take unwise macroeconomic decisions that affect the monetary system and balance of the country causing clear negative impacts on the rice chain. Several countries from the CAN (Colombia) and MERCOSUR (Argentina, Brazil and Uruguay) have been selected either as exporters or importers and consequently as potential competitors on the international markets...

Testing for differences in benefit transfer values between state and regional frameworks
Provedor de dados: 31
Autores: Rolfe,   John; Windle,   Jill.
Policy makers are often interested in transferring non-market estimates of environmental values from a ‘source’ study to predict economic values at a ‘target’ site. While most applications of the benefit transfer process involve an opportunistic search for suitable source studies, there are some examples available of more systematic approaches to developing a framework of values for benefit transfer processes. A key issue in developing such a framework is to deal with adjustment factors, where value estimates might vary systematically according to the context of the trade-offs. Previous research has identified that large differences in scope, such as between national and regional contexts, do affect values and hence benefit transfer. The research reported...

The nature of farm succession in three New South Wales communities
Provedor de dados: 31
Autores: Crockett,   Judith.
Farm transfer between generations of the same family has long been considered a highly significant aspect of rural ideology in Australia with major ramifications for farm management decision making. However, the importance attached to family farm succession has been increasingly questioned in current literature. Results from a study in rural culture in New South Wales support the contention that succession is declining in importance, highlighting instead that the wellbeing and education of younger family members is being placed ahead of expectations that children will automatically take over their parents' property and remain in farming. Implications of this trend for farm management are flagged and directions for further research explored.

A Comparison Of Choice Experiments And Actual Grocery Store Behavior: An Empirical Application To Seafood Products
Provedor de dados: 31
Autores: Hudson,   Darren; Gallardo,   Rosa Karina; Hanson,   Terrill R.
In this paper we compare results from an in-store field experiment and a mail survey choice experiment (CE) to investigate CE’s capacity in predicting grocery store market share. For the comparison, we used three seafood products: freshwater prawns, marine shrimp, and lobster. CE estimates were obtained via four econometric models: the conditional logit, the random parameter logit, the heteroskedastic extreme value, and the multinomial probit. We found that the level of control in the grocery store experiment and the choice of econometric model influenced the capacity of CE to predict grocery store market shares.

Autores: Iglesias,   Ana; Quiroga,   Sonia; Diz,   Agustin; Garrote,   Luis.
We evaluate the potential impacts and measure the potential limits of adaptation of agriculture to climate change. Pressures on land and water resources are expected to intensify existing risks in low latitude areas – e.g., South-East Asia deltas – and in regions with current water scarcity – e.g. Mediterranean, and create new opportunities in some northern temperate areas – e.g., Northern Russia, Northern Europe. The need to respond to these risks and opportunities is addressed by evaluating the costs and benefits of a number of technical and policy actions. The discussion aims to assist stakeholders facing the adaptation challenge and develop measures to reduce the vulnerability of the sector to climate change.

Impacts of Turkey’s Integration into the European Union on Agricultural Markets and Income Distribution
Provedor de dados: 31
Autores: Nazlioglu,   Saban; Erdem,   Ekrem.
This study analyzes the impacts of Turkey’s integration into the EU on price, production, consumption, and self-sufficiency in the selected agricultural markets (wheat, maize, sugar, milk, beef, lamb, and poultry). The study also examines the welfare and the income distribution impacts of the integration. A partial equilibrium model, Modéle Internationale Simplifié de Simulation (MISS), is used to simulate the impacts of the integration on the agricultural markets and Gini coefficients are calculated to examine the income distribution effects. The results show that the integration has substantial impacts on the selected agricultural markets in Turkey and deteriorates the distribution of income among the selected Turkish producers.

Van-e jövője az agrárgazdaságtannak mint önálló tudománynak?
Provedor de dados: 31
Autores: Ferto,   Imre.
Az agrárgazdaságtannal foglalkozók mint tudományos közösség előtt komoly kihívások állnak. Az elmúlt évtizedekben a hagyományos agrárgazdaságtan művelésének külső és belső feltételei gyökeresen megváltoztak. Ezek közül talán a legjelentősebb, hogy az agrárgazdaságtan mint szakma iránti kereslet csökkenésével, illetve a kereslet szerkezetének megváltozásával a szakma „láthatósága” is visszaesett, melynek legfontosabb jelei a tanszékek számának zsugorodása, illetve a stagnáló tudományos társasági élet. Az agrárgazdaságtant művelők azonban eddig sikeresen alkalmazkodtak a változásokhoz, ami az agrárgazdaságtan horizontjának folyamatos bővülésével járt. Az agrárgazdaságtan mint önálló diszciplína életben maradásához azonban világos és előrelátó stratégia...

A Tisza-tó jelentős változásokat idézett elő a térség életében, módosult a települések térbeli kiterjedése. Ez a fajta térmódosulás a tanulmányban bemutatott ábrákon kiválóan végigkövethető. Sarud, Abádszalók és Tiszafüred esetében egyértelműen megállapítható, hogy a települések térszerkezetének eltolódása a Tisza-tó partján kínálkozó turisztikai lehetőségek hatására következett be. A településkép beépítettségében, új településrészek kialakításában, a település arculatának módosulásában szintén közrejátszott a Tisza-tó léte. A strandok településformáló hatása is jelentős a feléjük vezető lineáris infrastruktúrák fejlődésében, az út mentén lévő telkek árainak felértékelésében és a parton végbemenő változásokban (például Abádszalók).

Economic evaluation of beef cattle production systems in China
Provedor de dados: 31
Autores: Gong,   Wendy; Parton,   Kevin A.; Zhou,   Zhang-Yue; Cox,   Rodney J.
The livestock industry in China has undergone massive changes since the liberalisation of markets started in 1985. The beef sector is no exception to this transition with production and consumption increasing faster than all other meats in the last two decades. The number of cattle has nearly doubled since 1980 to be around 141.6 million in 2005 and beef production has increased at a much faster rate than the cattle inventory. As the third largest beef producing country in the world, China exports and imports beef cattle. The emerging Chinese market has generally been seen as an opportunity for the Australian red meat industry. However, given the rate of increase in output, China may also provide a threat. With this in mind, understanding the current beef...

Ignoring the Multi-species Aspect of Labor Supply Decisions in Spatially Explicit Bio-economic Fishery Models
Provedor de dados: 31
Autores: Stafford,   Tess.
This paper analyzes the bias associated with ignoring the multi-species aspect of labor supply decisions in spatially explicit bioeconomic fishery models.  Recent advancements have been made to simultaneously model the biology of a marine species and the strategic behavior of harvesters over both time and space in order to more accurately predict the effect of regulatory policies on harvester effort and resource population.  These models assume a nested choice structure in which the harvester first faces a dichotomous decision between fishing for the target species or not on a given day and then chooses a location to fish conditional on participation.  This structure implicitly groups all non-target species options together in the first nest forcing...

Reducing Agriculture's Nitrogen Footprint: Are New Policy Approaches Needed?
Provedor de dados: 31
Autores: Ribaudo,   Marc.
Nitrogen is the single most important input a farmer can control to increase crop yields on nonirrigated fields. Given this, and the fact that nitrogen has been a relatively inexpensive input, farmers have an economic incentive to “apply a little extra” to ensure that crops have the necessary nutrients when they need them most. As a consequence, excess nitrogen remains in the soil and freely moves into water resources or into the atmosphere. Agriculture is the single largest source of nitrogen compounds entering the environment in the U.S., contributing 73 percent of nitrous oxide emissions, 84 percent of ammonia emissions, and 54 percent of nitrate emissions in recent years. The production and release of nitrogen, however, has greatly changed the Earth’s...

In Afghanistan, the 2007/08 rapid rise in wheat prices impacted urban and rural household food security, with observed declines in food consumed, calories, protein, and dietary diversity. Households traded off quality for quantity, moving away from micronutrient-rich foods like meat, fruit, and vegetables toward staples. Food price shocks can exacerbate chronically low levels of nutrient intake in countries with large populations living in poverty with generally poor diets.

Quasi–least squares (QLS) is an alternative method for estimating the correlation parameters within the framework of the generalized estimating equation (GEE) approach for analyzing correlated cross-sectional and longitudinal data. This article summarizes the development of QLS that occurred in several reports and describes its use with the user-written program xtqls in Stata. Also, it demonstrates the following advantages of QLS: (1) QLS allows some correlation structures that have not yet been implemented in the framework of GEE, (2) QLS can be applied as an alternative to GEE if the GEE estimate is infeasible, and (3) QLS uses the same estimating equation for estimation of Β as GEE; as a result, QLS can involve programs already available for GEE.

The objective of this research is to identify and quantify the motivations for organic grain farming in the United States. Survey data of US organic grain producers were used in regression models to find the statistical determinants of three motivations for organic grain production, including profit maximization, environmental stewardship, and an organic lifestyle. Results provide evidence that many organic grain producers had more than a single motivation and that younger farmers are more likely to be motivated by environmental and lifestyle goals than older farmers. Organic grain producers exhibited a diversity of motivations, including profit and stewardship.

This paper derives unbalanced versions of the test statistics for firstorder serial correlation and random individual effects summarized in Sosa-Escudero and Bera (2001, Stata Technical Bulletin Reprints, vol. 10, pp. 307–311), and updates their xttest1 routine. The derived test statistics should be useful for applied researchers faced with the increasing availability of panel information where not every individual or country is observed for the full time span. The test statistics proposed here are based on ordinary least-squares residuals and hence are computationally very simple.

A kukorica és a vágósertés felvásárlási árának és mennyiségének ciklikussága
Provedor de dados: 31
Autores: Hegedusne Baranyai,   Nora.
A vizsgálatok a rendszerváltozást követő időszakra vonatkozó piaci folyamatok – árak, felvásárolt mennyiségek – havi változásainak elemzésére irányultak. Célként fogalmazódott meg annak a hipotézisnek az igazolása, miszerint piacgazdasági körülmények között nem elhanyagolható rövid távú ciklikus ingadozásokkal szükséges számolni. A kukorica felvásárlási áránál öt teljes ciklus figyelhető meg az ár alakulásában 1992 januárja és 2011 januárja között. A ciklikus periódusok hossza 3-4 évre tehető. A vágósertésnél szintén öt ciklus rajzolódott ki a vizsgált időszakban. A hullámok hossza változó volt. A sertésáraknál a leghosszabbnak az utolsó előtti tekinthető, a maga három és fél évével.

Speaking Stata: Turning over a new leaf
Provedor de dados: 31
Autores: Cox,   Nicholas J.
Stem-and-leaf displays have been widely taught since John W. Tukey publicized them energetically in the 1970s. They remain useful for many distributions of small or modest size, especially for showing fine structure such as digit preference. Stata’s implementation stem produces typed text displays and has some inevitable limitations, especially for comparison of two or more displays. One can re-create stem-and-leaf displays with a few basic Stata commands as scatterplots of stem variable versus position on line with leaves shown as marker labels. Comparison of displays then becomes easy and natural using scatter, by(). Back-to-back presentation of paired displays is also possible. I discuss variants on standard stem-and-leaf displays in which each distinct...

Convergence in Agriculture: Evidence from the European Regions
Provedor de dados: 31
Autores: Alexiadis,   Stilianos.
Although there have been numerous studies on regional convergence, agriculture has received far less attention. In this study, the intention is to augment the existing literature by testing for convergence in agricultural productivity among the EU-26 regions. A low rate of absolute convergence is estimated over the period 1995-2004 whilst evidence of club convergence is apparent.

Preference erosion effects on the agricultural sector of the EU’s Mediterranean Partner Countries
Provedor de dados: 31
Autores: Kavallari,   Aikaterini; Schmitz,   P. Michael.
This paper analyses preference erosion effects on the agricultural sector of the EU’s Mediterranean Partner Countries (MPCs) with the partial equilibrium multi-commodity multi-region world trade model AGRISIM. Supposing that the preferences to the MPCs granted by the EU remain as of 2001 then the effects are evident for high protected markets like beef in Turkey, milk and rice in Morocco and olive oil in the MPCs. Supposing a free trade area between the EU and the MPCs, then the impacts are high for beef, milk and sugar. The farmers’ income decreases, but the consumers and the taxpayers benefit from lower prices and the overall welfare in all MPCs increases.

Using climate information to approximate the value at risk of a forward contracted canola crop
Provedor de dados: 31
Autores: Wallace,   Garry E.; Samsul Huda,   A.K.
In recent decades farmers have used financial instruments such as cash forward contracts to lock-in a price for increasing proportions of their crop through different stages of the production cycle. Given the high variability of the Australian climate this practice has inherent risk with drought induced crop failure being significantly probable. Under failed crop conditions farmers buy themselves out of the contracted position at prevailing prices thereby compounding the financial burden of crop failure. This paper reports on the role of the relatively recent developments in climate prediction, based on the SOI phase system, to develop crop yield probability distributions using regression approximation and to evaluate the Value at Risk of establishing a...

Price elasticities, joint products, and international trade
Provedor de dados: 31
Autores: Piggott,   Nicholas E.; Wohlgenant,   Michael K.
This paper extends the basic results of Houck’s insight for derived demand elasticities for the case of joint products by allowing for the possibility of the joint and raw products being traded. Theoretical relationships between individual demands for a set of jointly-produced commodities that are traded and composite demand for the raw product from which the joint products originate are derived. It is shown that while the derived price elasticity of domestic demand retains the same form as Houck’s original formula, the relevant price elasticities of demand to include in the formula are elasticities of total demand instead of domestic demand elasticities. Using the USA soybean industry as an example, this generalised formula that takes into account trade...

Main problems of agriculture and rural areas in Poland in the period of transformation and integration with European Union
Provedor de dados: 31
Autores: Zegar,   Jozef St.; Florianczyk,   Zbigniew.
Problems currently observed in Polish agriculture have different origins. Some of them have an historical background, while others are related to systemic transformation and forthcoming accession to the European Union. Most of the problems are common for all the candidate countries and most of them are also observed in the developed economies. Identification of these problems is the main purpose of this article. Special attention is paid to natural, human and capital resources available in rural areas. Possible development paths are pointed out. The article also covers most of the opportunities that may help overcome rural development problems in Poland in the wake of forthcoming accession, and their limitations.

A financial analysis of the effect of the mix of crop and sheep enterprises on the risk profile of dryland farms in south-eastern Australia
Provedor de dados: 31
Autores: Hutchings,   Timothy R.; Nordblom,   Thomas L.
This study analyses the financial risk faced by representative mixed-enterprise farm businesses in four regions of south-eastern Australia. It uses discrete stochastic programming to optimise the ten-year cash flow margins produced by these farms, operating three alternative farming systems. Monte Carlo simulation analysis is used to produce a risk profile for each scenario, derived from multiple runs of this optimised model, randomised for commodity prices and decadal growing season rainfall since 1920. This analysis shows that the performance of the enterprise mixes at each site is characterised more by the level of variability of outcomes than by the mean values of financial outputs. It demonstrates that relying on mean values for climate and prices...

Growth Management Policies for Exurban and Suburban Development: Theory and an Application to Sonoma County, California
Provedor de dados: 31
Autores: Newburn,   David A.; Berck,   Peter.
This study examines the effectiveness of growth management policies on influencing future patterns of exurban and suburban development. We initially estimate a spatially explicit model of residential development with parcel data in Sonoma County, California. This estimated model is then used to simulate the effect of urban growth boundaries (UGBs) versus allowing municipal sewer service expansion. The UGB policy decreases the amount of suburban development but is less effective in managing exurban development. The downzoning policy in agricultural and resource areas reduces the amount of exurban development, but only partially due to the prevalence of grandfathered lots in rural areas.

Design efficiency for non-market valuation with choice modelling: how to measure it, what to report and why
Provedor de dados: 31

We review the basic principles for the evaluation of design efficiency in discrete choice modelling with a focus on efficiency of WTP estimates from the multinomial logit model. The discussion is developed under the realistic assumption that researchers can plausibly define a prior belief on the range of values for the utility coefficients. D-,A-,B-,Sand Cerrors are compared as measures of design performance in applied studies and their rationale is discussed. An empirical example based on the generation and comparison of fifteen separate designs from a common set of assumptions illustrates the relevant considerations to the context of non-market valuation, with particular emphasis placed on Cefficiency.

The Effects of Vertical Organization on the Pricing of Differentiated Products
Provedor de dados: 31
Autores: Shi,   Guanming; Chavas,   Jean-Paul.
We investigate differentiated product pricing and the effects of vertical organization under imperfect competition. We rely on vertical measures of concentration (termed VHHI) to study how the exercise of market power varies with substitution/complementarity relationships among products and vertical structures. This approach is applied to U.S. soybean seed pricing under vertical integration versus licensing. We find evidence that vertical organization affects seed prices, with an impact ranging from 1.87% to 13.6% of the mean price. These effects vary by institutional setup.We also find that complementarity can mitigate price enhancements associated with market concentration.

The Sustainability of Intensive Livestock Areas (ILAS): Network System and Conflict Potential from the Perspective of Animal Farmers

The present study has determined the perceived consequences of an ILA on the production conditions of livestock farming systems based on the advantages of an agglomerated agri-food industry and the disadvantages of an increasing livestock concentration. It became obvious that the benefits of such ILAs can be understood according to their human and social capital. These elements, however, are both associated with a low geographic responsiveness to any increase in problems and so cause land use conflicts to increase. Their perception of the effects of being located within an ILA caused the livestock farmers in this survey to consider their production conditions more when formulating their demands with respect to policies concerning regional development and...

Az előhasi üszőktől született borjak növendék állományon belül történő elszámolásának hatása vagyont és eredményt csökkentő tételként jelentkezik. Azt, hogy az elszámolás során keletkező különbözet milyen arányban jelenik meg vagyont és eredményt csökkentő tételként, a korosbítás gyakorlata is jelentősen befolyásolja. Ha az állományt az első korcsoport után választják szét, nagyobb hányad kompenzálja a tejre jutó költségnövekedést és kisebb lesz a vagyoncsökkenés. Minél magasabb korcsoportban sorolják át a húshasznosítású állatokat, annál nagyobb arányban csökkenti a vagyont és az eredményt...

This article is devoted to changes in the functional structure of Poland’s rural areas in the years 1988-1999, that is – in the period of transition from the socialist to market economy and the country’s preparations for the EU accession. As the result of functional classification of rural areas carried out in 1999, it proved possible to identify ten functional classes, which can be associated into five groups (i.e. areas with an agricultural function, with equal contribution from different functions, with prevalent forestry, with prevalent tourist/rest-and-recreation function, and with prevalent non-agricultural function). The functional classification obtained revealed that the ten-year period brought a strengthening of the agricultural function in...

Evolution of tubewell ownership and production in the North China Plain

Autores: Wang,   Jinxia; Huang,   Jikun; Rozelle,   Scott.
The overall aim of the present paper is to better understand the evolution of tubewell ownership in the North China Plain, especially focusing on the factors that determine ownership and its effect on production. Based on a random sample of 30 villages in three counties in the Hai River Basin, our results show that collectively owned tubewells have been gradually privatised. The analyses demonstrate that increasing water and land scarcity and policy intervention (mainly fiscal and financial subsidies for tubewell investment) leads to the observed shifts in tubewell ownership patterns. The results also show that the privatisation of tubewells has affected cropping patterns in the North China Plain. When villages shift towards private tubewells, farmers move...

Evaluating the Performance of U.S. Supermarkets: Pricing Strategies, Competition from Hypermarkets, and Private Labels
Provedor de dados: 31
Autores: Volpe,   Richard J., III.
This study draws upon literature from the fields of agricultural economics, industrial organization, and business to study the performance of supermarkets in the United States. The empirical work draws from a rich dataset on the characteristics of supermarkets across the U.S. to test several hypotheses. Supermarkets utilizing everyday low pricing operate more efficiently than those using other strategies. Stores increase their performance by using strategies of their closest competitors. Competition with hypermarkets results in decreased supermarket performance, especially for smaller stores. Increases in private label sales relative to national brand sales are not necessarily related to increased performance.

This paper concerns the economic assessment of a nonconventional technology to provide a cheap food and/or feed for many developing countries, using wasted resources, i.e. coastal arid areas irrigated directly with seawater to grow a halophyte crop(Salicornia-sos-7). It was cultivated for two successive years in Kuwait. The analysis showed that the harvested yield was 20 tons per hectare, which provided 12.42 MT of straw for sale and 1.7 MT of oil seeds for processing. Processed seeds of 1-hectare provide 425 kg of food oil and 1.1 MT of feed meal.Under Kuwait conditions, on per hectare basis, the total costs of production( fixed &amp;variable costs)were $3088. However,simulation of this technology under a conventional developing country like Egypt with...

Demand for Private Marketing Expertise by Organic Farmers: A Quantile Analysis Based on Counts
Provedor de dados: 31
Autores: Lohr,   Luanne; Park,   Timothy A.
We study the demand by organic farmers for technical advice using a quantile regression for the demand of organic farmers for consultations with private information providers. There is substantial heterogeneity in the impact of critical explanatory variables on consultations of organic farmer. Larger farm size has a positive effect on contacts, but the effect is absent for the highest number of consultations. Internet use has a positive marginal effect on visits to private information providers across each quantile, suggesting that expanded efforts to deliver programs through web-based resources are a useful investment for information providers.

In Punjab, the influx of migrant labour particularly in agriculture sector started with the green revolution and picked up subsequently. Due to monoculture in the cropping pattern, the state has become largely dependent on migrant labourers for various agricultural operations. The influx of seasonal as well as permanent labour from outside has led to various socio-economic problems in Punjab. In the wake of this, the present study was purposively conducted in the Central Zone of Punjab for the year 2011 to find the causes and impact of labour in-migration in Punjab. A total of 105 respondents belonging to the states of Bihar, Uttar Pradesh, Jharkhand, Madhya Pradesh and Nepal constituted the sample frame. The results have revealed that better income and...

Internationalization and Firm Performance in Agribusiness: Empirical Evidence from European Cooperatives
Provedor de dados: 31
Autores: Heyder,   Matthias; Makus,   Christian; Theuvsen,   Ludwig.
The ongoing internationalization of markets has become a major issue also for companies of the agribusiness. Nevertheless, neither the degree of internationalization of agribusiness firms nor the internationalization-performance relationship in the agribusiness sector have been analyzed thoroughly so far. To help fill this void, we use panel data compiled from annual reports and balance sheets to investigate the internationalization as well as the internationalization-performance relationship of 21 leading European cooperatives in the dairy and meat sectors. Our results indicate that internationalization has a significant positive impact on firm performance.

In the Beef CRC, Sustainable Beef Profit Partnership (BPP) teams meet regularly to measure their current performance, set targets for future productivity increases, and use a profitability framework to assess the potential impact of improvements, innovations and new technologies in their beef businesses. Their decisions and actions are based on the Continuous Improvement and Innovation (CI&amp;I) process. Capacity building and partnership outcomes are also assessed, and the BPP teams are supported with appropriate tools and resources. In this paper the achievements of the project to date are assessed against the project targets and issues in implementation of the project are discussed.

Fish demand patterns in nine Asian countries were investigated using a multistage budgeting framework allowing a disaggregated approach to analysing fish consumption. This paper highlights the heterogeneity of fisheries products in terms of species, sources and cultural responses of consumers, factors that are important in fish demand under the Asian setting. Specifically, fish demand by income groups were compared to determine how the low- and high-income households respond to price and income changes. Results showed that the estimated price and income elasticities of all fish types included in the study were relatively more elastic among the poorer households.

Towards a Diagnostic Instrument to Identify Improvement Opportunities for Quality Controlled Logistics in Agrifood Supply Chain Networks
Provedor de dados: 31
Autores: van der Vorst,   Jack G.A.J.; van Kooten,   Olaf; Pieternel,   A. Luning.
Western-European consumers have become not only more demanding on product availability in retail outlets but also on other food attributes such as quality, integrity, and safety. When (re)designing food supply-chain networks, from a logistics point of view, one has to consider these demands next to traditional efficiency and responsiveness requirements. The concept ‘quality controlled logistics’ (QCL) hypothesizes that if product quality in each step of the supply chain can be predicted in advance, goods flows can be controlled in a pro-active manner and better chain designs can be established resulting in higher product availability, constant quality, and less product losses. The paper discusses opportunities of using real-time product quality information...

The role of broadband developments financed from EU Structural Funds in the enhancement of regional cohesion in the NMS-10
Provedor de dados: 31
Autores: Feko,   Adrienn; Sass,   Magdolna; Nagy,   Gabor.
This paper examines if broadband Internet access (‘broadband’) developments enhance regional cohesion in ten New Member States (NMS-10) of the European Union. It focuses on broadband developments in these countries financed from Structural Funds (SF). The importance of their impacts is potential, but not automatic. The topic is well established theoretically, versus business. There is no conclusive evidence yet empirically. Broadband is perceived here as an essential part of ICT, enabling the spread and use of ICT. The paper analyses (1) the regional dimension of broadband access in the NMS-10, (2) the recognition of broadband-cohesion links by NMS-10 governments, and (3) the priority given to broadband in SF spending. The impact of broadband developments...

Adoption of Technology, Management Practices, and Production Systems by U.S. Beef Cow-Calf Producers
Provedor de dados: 31
Autores: Pruitt,   J. Ross; Gillespie,   Jeffrey M.; Nehring,   Richard F.; Qushim,   Berdikul.
Using USDA’s Agricultural Resource Management Survey data, factors leading to the adoption of technology, management practices, and production systems by U.S. beef cow-calf producers are analyzed. Binary logit regression models are used to determine impacts of vertical integration; region of the U.S.; farm size, diversification, and tenure; and demographics on adoption decisions. Significant differences were found in adoption rates by region of the U.S., degree of vertical integration, and size of operation, suggesting the presence of economies of size and vertical economies of scope. Results also indicate high degrees of complementarity among technologies, management practices, and production systems.

Fixed Effects Estimation of the Intensive and Extensive Margins of Irrigation Water Demand
Provedor de dados: 31
Autores: Hendricks,   Nathan P.; Peterson,   Jeffrey M.
Irrigation water demand is estimated using field-level panel data from Kansas over 16 years. The cost of pumping varies over time due to changes in energy prices and across space due to differences in the depth to water. Exploiting this variation allows us to estimate the demand elasticity while controlling for field-farmer and year fixed effects. Fixed effects also allow us to control for land use without an instrument or assumptions about the distribution of errors. Our estimates of water demand are used to calculate the cost of reducing irrigation water use through water pricing, irrigation cessation, and intensity-reduction programs.

Autores: King,   Katie; Zulauf,   Carl R.
Farmers and other buyers and sellers of commodities use options in their marketing strategies. A cost of buying put and call options is the decay in option premium that occurs from the time an option position is established until the time the option position is closed out. This article finds that the average option premium decay cost associated with buying December corn and November soybean put and call options is relatively small if the option position is closed out before mid-to-late June. After this date the average option premium decay cost begins to accelerate, resulting in and increasing cost of using options to market corn and soybeans.

Do Australian woolgrowers manage price risk rationally?
Provedor de dados: 31
Autores: Deane,   Paul; Malcolm,   Bill.
Australian woolgrowers have not adopted price risk management in the last decade. This is despite a concerted effort at various times by participants in the wool industry to encourage growers to use hedging/forward selling. The explanation for the reluctance of woolgrowers to use futures market and forward pricing instruments lies not in market failure but in characteristics of wool producing farm businesses. In particular, the degree of business and financial risk and the interaction between the two helps to explain why woolgrowers do not use futures. In the context of the whole farm system, Australian woolgrowers are behaving as rational managers of wool price risk.

We use observational data from 22 elementary schools and over 48,000 child-day observations to examine the relationship between the number of fruit and vegetable items and the consumption patterns of children during school lunch. We find that each additional fruit or vegetable item that is offered increases the fraction of children who eat at least one serving of fruits and vegetables by 12 percent. We also use our observational data to provide practical information about which items are most likely to be eaten by children during lunch and compare this to the cost and nutritional quality of these items.

Bioeconomic analysis of protected area use in fisheries management
Provedor de dados: 31
Autores: Greenville,   Jared W.; MacAulay,   T. Gordon.
Protected areas in fishery management have been suggested to hedge management failures and variation in harvests. In this paper, a stochastic bioeconomic model of a two-species fishery in the Manning Bioregion is used to test the performance of protected areas as a management tool in a fishery. The establishment of a protected area is analysed under the assumption of heterogenous environments that are linked via density-dependent or sink-source stock dispersal relationships. The sensitivity of the results to different degrees of management is also explored. The model is applied to the Ocean Prawn Trawl, and Ocean Trap and Line fisheries within Manning Bioregion in New South Wales, Australia. The focus of the study is placed on the biological and...

Autores: Robertson-Carolan,   Jessica; Parcell,   Joseph L.; Patterson,   David J.; Eakins,   Roger; Franken,   Jason R.V.
An important component of the beef cow herd is the contribution of the dam to herd profitability. Yet, no research has contributed to valuing the dam’s genetic contribution to herd quality performance or profitability. This paper examines how managing for dam genetic pedigree quality grade affected the outcome of calf crop quality, and simulates the economic impact for different levels of quality premium. The results show that managing for dam pedigree genetics beyond three generations in the herd has little economic value for producers.

Contour–enhanced funnel plots for meta–analysis
Provedor de dados: 31
Autores: Palmer,   Tom M.; Peters,   Jaime L.; Sutton,   Alex J.; Moreno,   Santiago G.
Funnel plots are commonly used to investigate publication and related biases in meta-analysis. Although asymmetry in the appearance of a funnel plot is often interpreted as being caused by publication bias, in reality the asymmetry could be due to other factors that cause systematic differences in the results of large and small studies, for example, confounding factors such as differential study quality. Funnel plots can be enhanced by adding contours of statistical significance to aid in interpreting the funnel plot. If studies appear to be missing in areas of low statistical significance, then it is possible that the asymmetry is due to publication bias. If studies appear to be missing in areas of high statistical significance, then publication bias is a...

The Role of Farmland in an Investment Portfolio: Analysis of Illinois Endowment Farms
Provedor de dados: 31
Autores: Noland,   Kevin; Norvell,   Jonathan; Paulson,   Nicholas D.; Schnitkey,   Gary D.
The recent financial crisis has renewed interest in alternative asset classes such as farmland. Previous work has shown that farmland may provide expected return premiums while adding little additional risk to a diversified portfolio. However, these studies have been based on relatively short time periods and aggregated data on farmland returns. This analysis contributes to this literature using farm-level data from the University of Illinois endowment farms, providing additional evidence that farmland could play a favorable role within an investment portfolio. The implications of these results extend to the use of farmland within general investment portfolios.

Estimating parameters of dichotomous and ordinal item response models with gllamm
Provedor de dados: 31
Autores: Zheng,   Xiaohui; Rabe-Hesketh,   Sophia.
Item response theory models are measurement models for categorical responses. Traditionally, the models are used in educational testing, where responses to test items can be viewed as indirect measures of latent ability. The test items are scored either dichotomously (correct–incorrect) or by using an ordinal scale (a grade from poor to excellent). Item response models also apply equally for measurement of other latent traits. Here we describe the one- and two-parameter logit models for dichotomous items, the partial-credit and rating scale models for ordinal items, and an extension of these models where the latent variable is regressed on explanatory variables. We show how these models can be expressed as generalized linear latent and mixed models and...

Autores: Cicia,   Gianni; Cembalo,   Luigi; Del Giudice,   Teresa; Scarpa,   Riccardo.
The intense process of internationalization of the food market is giving rise to new competitive scenarios. Growing market shares on the part of new export countries, along with other consumer and retail issues, impose different marketing policies for agri-food products. In particular, greater consumer awareness of environmental and health issues is changing the structure of demand for fresh products. In the past, the country of origin and a good quality/price ratio were the main strategic strengths for gaining and maintaining international market shares. Nowadays, market shares are gained by moving towards new product attributes, namely environmental friendliness and food safety. This paper draws attention to new, more successful marketing strategies. The...

The Quality-Quantity Trade-off in the Principal-Agent Framework
Provedor de dados: 31
Autores: Olmos,   Marta Fernandez; Martinez,   Jorge Rosell.
This paper uses the principal-agent theory to analytically investigate the optimal incentive-based compensation contract that a processor should offer to a grower performing efforts in quantity and quality. In this process, we contribute to the substantive literature on multi-task principal-agent models by analyzing the quality-quantity trade-off and studying the implications of such a relationship in the principal-agent framework. One striking result of these effects is that, under appropriate incentive-based grower’s compensation, the processor may encourage grower’s effort in quality without crowding out grower’s effort in quantity.

Soil conservation and technical efficiency among hillside farmers in Central America: a switching regression model
Provedor de dados: 31
Autores: Solis,   Daniel; Bravo-Ureta,   Boris E.; Quiroga,   Ricardo E.
The main objective of this paper is to evaluate and analyse technical efficiency (TE) levels for hillside farmers under different levels of adoption of soil conservation in El Salvador and Honduras. A switching regression model is implemented to examine potential selectivity bias for high and low level adopters, and separate stochastic production frontiers, corrected for selectivity bias, are estimated for each group. The main results indicate that households with above-average adoption show statistically higher average TE than those with lower adoption. Households with higher adoption have smaller farms and display the highest partial output elasticity for land. Constraints in the land and credit markets are likely explanations for these differences. In...

Tariffs and steel: US safeguard actions
Provedor de dados: 31
Autores: Greenville,   Jared W.; MacAulay,   T. Gordon.
A multiproduct spatial equilibrium model of world steel trade is presented in this paper. The model is used to analyse the impacts of the safeguard trade barriers brought about by the USA in order to protect their domestic industry from the so-called unfair competition. Emphasis is placed on the likely effect on the Australian industry and possible policy responses available to the industry. A case study is made of Australia’s three largest export products; namely, slab, hot-rolled and cold-rolled steel, which share some substitutability in supply and demand because of the nature of the industry. As a result of the safeguard barriers to steel trade, world steel prices fell and trade shifted away from the USA to other importing regions.

Rotational grazing adoption in cattle production under a cost-share agreement: does uncertainty have a role in conservation technology adoption?
Provedor de dados: 31
Autores: Kim,   Seon-Ae; Gillespie,   Jeffrey M.; Paudel,   Krishna P.
Rotational grazing has been promoted as a best management practice with environmental benefits and associated higher revenue. Its adoption rate has been relatively low. This study investigates the role of uncertainty in the adoption of rotational grazing with a cost-share by cattle producers. Mail survey results indicate that 63–71 per cent of cattle producers are uncertain about adoption with a government cost-share. The study suggests that the possibility of uncertainty should be considered in cases where willingness-to-pay is elicited in the context of adoption of technology.

We discuss the semi-nonparametric approach of Gallant and Nychka (1987, Econometrica 55: 363–390), the semiparametric maximum likelihood approach of Klein and Spady (1993, Econometrica 61: 387–421), and a set of new Stata commands for semiparametric estimation of three binary-choice models. The first is a univariate model, while the second and the third are bivariate models without and with sample selection, respectively. The proposed estimators are √n consistent and asymptotically normal for the model parameters of interest under weak assumptions on the distribution of the underlying error terms. Our Monte Carlo simulations suggest that the efficiency losses of the semi-nonparametric and the semiparametric maximum likelihood estimators relative to a...

Effects of Environmental Regulation and Urban Encroachment on California’s Dairy Structure
Provedor de dados: 31
Autores: Sneeringer,   Stacy E.
Environmental regulatory compliance costs are often cited as a factor in dairy location decisions, but few studies estimate the impacts of regulation in this sector. This article uses California dairy regulations to examine the pollution haven hypothesis in agriculture. Dairy industry regulation has varied regionally within the state, with the more strictly regulated Southern California region losing production and the more environmentally lenient Central Valley gaining production. Results show that even after controlling for population density and property values, regulation had significant negative effects on dairying in Southern California.

An Environmental Trade Case Study: Agricultural Conservation Easement Pays Off Environmental Penalty
Provedor de dados: 31
Autores: Fisher,   Donald A.
Agricultural conservation easements have been traditionally used to transfer or extinguish development rights on farm and ranch land in order to preserve open space and conservation and natural resources. These transfers are typically made with governmental agencies or Internal Revenue Service qualified land trusts. Usually this process is initiated because the property owner wants to ensure future agricultural use as well as conserve natural resources in exchange for financial benefits in either payments and/or tax credits.

Technology adoption in the Australian beef industry has been low and slow compared to that in the intensive livestock and cropping industries. Adoption needs to be higher and faster to fully capture the benefits from new beef genetic and other technologies. The principles of rapid improvement and innovation, and accelerated adoption, provide an innovative solution to this problem. In the Beef CRC, Sustainable Beef Profit Partnership (BPP) teams meet regularly to assess their current performance, set targets for future productivity increases, and use a profitability framework to assess the potential impact of new technology in their beef businesses. Their thinking, decisions and actions are based on the principles and process of Continuous Improvement and...

Hired hooves: Transactions in a south Indian village factor market
Provedor de dados: 31
Autores: Mueller,   Rolf A.E.; Prescott,   Edward S.; Sumner,   Daniel A.
Bullocks are an important resource in Indian agriculture where they are used as draft animals. Previous research suggests that farmers who do not own bullocks, or own bullocks in insufficient numbers relative to their land holdings, adjust bullock‐land ratios through transactions in the land market, rather than by hiring bullock services. The reasons given for this behaviour are that there are ‘inhibited’ or ‘missing’ village markets for bullock services. Results from a survey of the activities and transactions of six bullock contractors during an entire cropping period show that village markets for bullock services exist continuously and are far from being inhibited. Close monitoring of the bullock contractors’ transactions supplied rich evidence of the...

In this article, we briefly review the role of the propensity score in estimating dose–response functions as described in Hirano and Imbens (2004, Applied Bayesian Modeling and Causal Inference from Incomplete-Data Perspectives, 73–84). Then we present a set of Stata programs that estimate the propensity score in a setting with a continuous treatment, test the balancing property of the generalized propensity score, and estimate the dose–response function. We illustrate these programs by using a dataset collected by Imbens, Rubin, and Sacerdote (2001, American Economic Review 91: 778–794).

A kistermelők tömegei elsősorban e szervezetekhez csatlakozva tudnak beszállítani. Magyarországon még nem terjedtek el eléggé a termelői szerveződések a zöldség-gyümölcs ágazatban, ezért nem töltik be azt a szerepet a nagy kereskedelmi láncoknak történő beszállításban, mint az Európai Unióban. Ez az egyik alapvető oka a hazai zöldség-gyümölcs kisárutermelők beszállítási nehézségeinek.

Dynamic regulation of nonpoint source pollution when the number of emitters is large
Provedor de dados: 31
Autores: Tsur,   Yacov; de Gorter,   Harry.
When a nonpoint source pollution process involves many polluters, each taking his own contribution to aggregate pollution to be negligible, ambient-based policies become ineffective due to lack of strategic interactions between dischargers. We offer a regulation mechanism for this case. The mechanism consists of inter-period and intra-period components. The first exploits ambient (aggregate) information to derive the optimal pollution and aggregate emission processes and the ensuing social price of emission. The intra-period mechanism takes as given the social price of emission and implements the optimal output-abatement-emission allocation across the heterogenous, privately informed firms in each time period. The mechanism gives rise to the full...

Production, processing, distribution, and consumption of a wide variety of products in the food sector have different ranges of environmental impacts. Methodologies used in environmental impact assessment differ in which set of impact categories is covered and which models are used to assess them. In the food sector, life cycle assessment results are mostly presented without any clear distinction of the principles applied to selecting the relevant methodology. In this paper, the most relevant life cycle impact assessment methodologies are determined from the list of recommended methodologies published recently in the international reference life cycle data system (ILCD) handbook. The range of the relevant impacts covered is considered as the main indicator...

Should I Make or Should I Buy? Innovation Strategies and Governance Structures in the Italian Food Sector
Provedor de dados: 31
Autores: Pascucci,   Stefano; Royer,   Annie; Bijman,   Jos.
This paper analyses the “make or buy” decision of food firms applied to innovation strategy using 389 Italian food firms data from the Unicredit 2007 database. We develop a set of hypothesis from three theoretical perspectives such as transaction cost economics, strategic management and resource-based view. Our paper aims at highlight whether or not different firm’s features can be linked to the decision to make or buy. We found out that these two decisions are positively interlinked. Moreover we also found out that it is difficult to indicate a clear-cut behaviour for the Italian food firms if we refer to making or buying decisions. We discuss these results and use them to bring some interesting outcomes to discuss managerial implications and/or policy...

An Assessment of the Informal Sector Trade in Kenya
Provedor de dados: 31
Autores: Gor,   Seth Omondi.
This study assesses the nature and practice of cross-border trade in Kenya with a view to filling the information gap on its patterns and key characteristics, a gap that has hitherto acted to hinder effective policy formulation. The study relies on information from a number of cross-border monitoring survey initiatives mounted by various institutions over the years. The study finds that informal cross-border trade accounts for more than 40 percent of the GDP and is therefore almost equivalent to formal trade. Efforts should be made to conceive policy suggestions that would optimize both formal and informal trade from the viewpoint of the national economy.

A Structural Land-Use Analysis of Agricultural Adaptation to Climate Change: A Proactive Approach
Provedor de dados: 31
Autores: Kaminski,   Jonathan; Kan,   Iddo; Fleischer,   Aliza.
This article proposes a proactive approach for analyzing agricultural adaptation to climate change based on a structural land-use model wherein farmers maximize profit by allocating their land between crop-technology bundles. The profitability of the bundles is a function of four technological attributes via which climate variables‟ effect is channeled: yield potential; input requirements; yields' sensitivity to input use; and farm-level management costs. Proactive adaptation measures are derived by identifying the technological attributes via which climate variables reduce overall agricultural profitability, despite adaptation by land reallocation among bundles. By applying the model to Israel, we find that long-term losses stem from yield potential...

Autores: D'Emden,   Francis H.; Llewellyn,   Rick S.; Burton,   Michael P.
The purpose of this research is to improve understanding of conservation tillage adoption decisions by identifying key biophysical and socio-economic factors influencing no-till adoption by grain growers across four Australian cropping regions. The study is based on interviews with 384 grain growers using a questionnaire aimed at eliciting perceptions relating to a range of possible long- and short-term agronomic interactions associated with the relative economic advantage of shifting to a no-tillage cropping system. Together with other farm and farmer-specific variables, a dichotomous logistic regression analysis was used to identify opportunities for research and extension to facilitate more rapid adoption decisions. The broader systems approach to...

Autores: Liu,   Tao.
From the perspective of supply chain of agricultural products, by establishing Stackelberg game model based on triple supply chain, this paper researches the price formation and profit distribution mechanism of agricultural products under circumstance of non-cooperation and cooperation. The results show the main factors responsible for the hiking of prices of agricultural products as follows: the cost of agricultural products climbs incessantly; the circulation cost hovers at high level; the factor inputs of agricultural products are short; inflation pressure is incessantly mounting; the profit distribution of supply chain is irrational. Finally, corresponding countermeasures are put forward.

Site-Specific Simulation of Nutrient Control Policies: Integrating Economic and Water Quality Effects
Provedor de dados: 31
Autores: Burkhart,   Christopher S.; Jha,   Manoj K.
A watershed-based modeling system is developed to assess alternative nutrient abatement policies, including fertilizer taxes, application caps, and uniform reductions. A microeconometric model of nutrient use is estimated using farm-level data, prices, and spatially detailed soil and land characteristics. Results are interfaced with a physical watershed model to predict water quality changes. Simulations demonstrate differences in water quality effects across policies. For nitrate loads at the watershed outlet, an application cap provides slightly superior performance for small reductions, but a tax is more efficient under larger reductions. Phosphorus reductions at the subwatershed level vary but provide information about policy tradeoffs.

Autores: Herd,   Robert M.; Arthur,   Paul F.; Dibley,   K.; Mula,   D.; Snelgar,   T.; Thompson,   J.
This experiment investigated the benefits of feeding steers bred from parents known to be of high genetic merit for feed efficiency (HE; midparent net feed intake-estimated breeding value (NFI-EBV) ≤-0.3kg/day), medium efficiency (ME: midparent NFI-EBV &gt;-0.3 to 0.14 kg/day), or low efficiency (LE; midparent NFI-EBV ≥0.16kg/day). The steers were evaluated over a 251-day feeding period in a large commercial feedlot. Genetic superiority in NFI had a favourable impact on the commercial performance of Angus steers by reducing feed consumed with no adverse effect on final turnoff weight. Each HE steer consumed on average 2.60t of feed compared to 2.87t by the ME and LE steers, with no compromise in weight gain. The HE steers gained less subcutaneous ribfat...

Applying search theory to determine the feasibility of eradicating an invasive population in natural environments
Provedor de dados: 31
Autores: Cacho,   Oscar J.; Hester,   Susan M.; Spring,   Daniel.
The detectability of invasive organisms influences the feasibility of eradicating an infestation. Search theory offers a framework for defining and measuring detectability, taking account of searcher ability, biological factors and the search environment. In this paper, search theory concepts are incorporated into a population model, and the costs of search and control are calculated as functions of the amount of search effort (the decision variable). Simulations are performed on a set of weed scenarios in a natural environment, involving different combinations of plant longevity, seed longevity and plant fecundity. Results provide preliminary estimates of the cost and duration of eradication programs to assist in prioritising weeds for control. The...

The possible effects of the CAP Reform on farm employment in Hungary
Provedor de dados: 31
Autores: Elek,   Sander; Ferto,   Imre; Forgacs,   Csaba.
This study analyses the possible impacts of CAP reform on farm employment in an economically disadvantaged rural region in Hungary using survey among farmers. Results show that farmers are rather pessimistic about the employment effects of CAP reformy expecting a decrease in the number of farm jobs regardless of the type. Econometric analyses suggest that farm size in terms of area is positively related to the expected number of male employment on the farms, whilst the less favoured land has negative effects on the male employment except seasonal workers. Farms employing more labour expect thet number of full time female workers to slightly increase, whilst the number of part-time and seasonal employees is expected to decrease. Less favoured areas have...

The role of local production and the world price in setting local wheat, wool, and beef prices
Provedor de dados: 31
Autores: Frost,   Mark; Parton,   Kevin A.
The Australian dollar is considered primarily a commodity-based currency. The high level of commodity-based exports in Australia’s trade balance is given as an explanation. Accordingly changes in world commodity prices should bring commensurate changes in the value of the Australian dollar, such that changes in world commodity prices are only partially transmitted to the Australian economy and local farm-gate prices. If this relationship holds, then local farm-gate prices should be significantly less volatile than their respective world price. Variances in local prices would be due to local factors (e.g. variances in local production) rather than variances in the world price and international factors. This paper examines the farm-gate prices of Australia’s...

Welfare Effects of Anti-Sprawl Policies in the Presence of Urban Decline
Provedor de dados: 31
Autores: Bento,   Antonio M.; Franco,   Sofia F.; Kaffine,   Daniel T.
This paper extends first-best analysis of anti-sprawl policies, such as development taxes, and examines the welfare effects of development taxes in the presence of urban decline at the city core. We find that anti-sprawl policies generate several important feedbacks within the urban system, generating additional welfare gains and affecting the level of urban decline and suburban sprawl. Further, the optimal development tax exceeds the (first-best) Pigouvian level, irrespective of whether or not revenues are returned lump-sum to all landowners or earmarked for urban decline mitigation.

Autores: Stovring,   Henrik.
Background: When implementing new statistical procedures, there is often a need for simple—and yet computationally efficient—ways of numerically evaluating composite distribution functions. If the statistical procedure must support calculations for censored and noncensored cases, those calculations should be carried out using efficient computational implementations of both definite and indefinite integrals (e.g., calculation of tail areas of distribution functions).  Method: We developed a generic function evaluator such that users may specify a function using reverse Polish notation. As its argument the function evaluator takes a matrix of pointers and then applies the rows of this matrix to its internally defined stack of pointers. Accordingly, each row...

However, many times open space is valued most for what it is not: the absence of negative externalities associated with development of the open space. Florida has the most ambitious programme for acquiring conservation land of any state or nation in the world. Using evidence from Florida, this study determines whether being added to a conservation land acquisition list affects nearby property values. The Florida Department of Environmental Protection claims that being on the list should not trigger any changes in property values. The results of the hedonic regression...

With ‘Regional Territorial Agendas’ towards territorial cohesion?: The emergence of supra-regional coalitions in Europe and their future role in Cohesion Policy
Provedor de dados: 31
Autores: Knippschild,   Robert.
This paper focuses on current trends of regionalisation with supra-regional coalitions emerging in Europe. In the context of further European integration and institutionalisation of cross-border cooperation, functional integration in cross-border areas is developing. By exploiting cross-border territorial capital these coalitions might contribute to the concept of territorial cohesion stated and upgraded in the European Union’s Treaty of Lisbon. The paper considers the right scale for these emerging supra-regional coalitions and their implications for the European Spatial Development Policy. When elaborating on the right delineation of supra- or transnational regional coalitions and about policy options, ‘territorial knowledge’ on territorial...

Del distrito industrial al distrito rural: implicaciones teóricas para el desarrollo territorial
Provedor de dados: 31
Autores: Castillo,   Juan Sebastián; García,   María del Carmen.
As opposed to the traditional Marshallian Industrial District, the Rural District becomes a new concept for territorial development thanks to the qualitative changes of population occurring since 1970 in developed countries and since 1980 in Spain and Castilla-La Mancha. The urban areas are decreasing in importance and the urban hierarchy and center-periphery relations evolved into less hierarchic and multipolar relations. Rural-rural movements occurred in rural environments, from minor cores to region cores and/or higher populated cores as a reproduction of a center-periphery model at rural territorial level.

Incorporating Spatial Complexity into Economic Models of Land Markets and Land Use Change
Provedor de dados: 31
Autores: Chen,   Yong; Irwin,   Elena G.; Jayaprakash,   Ciriyam.
Recent work in regional science, geography, and urban economics has advanced spatial modeling of land markets and land use by incorporating greater spatial complexity, including multiple sources of spatial heterogeneity, multiple spatial scales, and spatial dynamics. Doing so has required a move away from relying solely on analytical models to partial or full reliance on computational methods that can account for these added features of spatial complexity. In the first part of the paper, we review economic models of urban land development that have incorporated greater spatial complexity, focusing on spatial simulation models with spatial endogenous feedbacks and multiple sources of spatial heterogeneity. The second part of the paper presents a spatial...

Future dairy farming systems in irrigation regions
Provedor de dados: 31
Autores: Ho,   Christie K.M.; Nesseler,   R.; Doyle,   Peter T.; Malcolm,   Bill.
The dairy industry in northern Victoria has been subject to rapid change in recent years, resulting in great diversity in the irrigated dairy farming systems in the region. Continuing analysis is needed of the various farming systems that may be viable in the future. This study examined possible development options for different farm systems to enable them to maintain financial viability. Four case studies, representative of different farm systems, were used. All four had options to combat the effects of declining terms of trade. However, the option most suitable for one case study may be unsuitable for another farm due to differences in resources, goals or skills. A key outcome of the study was the development of a robust approach to continually analyse...

Autores: Canning,   Patrick N.
In 2007, the U.S. food system accounted for almost 16 percent of the Nation’s energy budget. Between 1997 and 2002, over 80 percent of the increase in annual U.S. energy consumption was food related. Population growth, higher per capita food expenditures, and greater reliance on energy-using technologies boosted food-related energy consumption.

Economics of extended lactations in dairying
Provedor de dados: 31
Autores: Malcolm,   Bill.
This paper deals with the economic analysis and management implications of extending lactations in specialised dairy cows. The main conclusion from this study is that in the two dairy farm cases that have been investigated in depth, the use of extended lactations to achieve efficient herd reproduction is highly likely to give greater profit than alternative systems that could be implemented. This conclusion holds even after allowing for less than total persistency of cows embarking on extended lactations. The overall outcome of a change from having only 10-month lactations to having some cows in the herd milking for extended lactations is determined by the complex interactions of all of the major input, output, cost and income factors at work in a dairy...

Autores: Brennan,   John P.; Singh,   Rajinder Pal; Singh,   Inder Pal.
A comprehensive set of potential new feed grains for Australia was evaluated to help establish the options with the highest priorities for research. The cost-reducing impacts of the different options were analysed using a linear-programming model that determined the least-cost feed rations for the different livestock industries. Economic welfare analysis was then used to estimate the size and distribution of the benefits of research from the feed grains quality-improving research. The analysis revealed that there are only limited opportunities to improve the productivity and competitiveness of Australia’s livestock industries by improving the nutritional characteristics of feed grains.

Two postestimation commands for assessing confounding effects in epidemiological studies
Provedor de dados: 31
Autores: Wang,   Zhiqiang.
Confounding is a major issue in observational epidemiological studies. This paper describes two postestimation commands for assessing confounding effects. One command (confall) displays and plots all possible effect estimates against one of p-value, Akaike information criterion, or Bayesian information criterion. This computing-intensive procedure allows researchers to inspect the variability of the effect estimates from various possible models. Another command (chest) uses a stepwise approach to identify variables that have substantially changed the effect estimate. Both commands can be used after most common estimation commands in epidemiological studies, such as logistic regression, conditional logistic regression, Poisson regression, linear regression,...

Over the past three decades, the number of farming operations has remained relatively steady, but production has shifted to larger farms. Changes in production and marketing practices have facilitated—and have been facilitated by—organizational and distributional changes in agricultural production. Resulting changes in agricultural productivity helped keep prices for agricultural goods relatively low and reduced the environmental footprint for each unit of agricultural output produced, but not without tradeoffs.

Provedor de dados: 31
Autores: Conner,   David S.; Izumi,   Betty T.; Liquori,   Toni; Hamm,   Michael W.
Many scholars and activists are interested in the potential for school-based childhood nutrition programs to positively impact the U.S. agri-food system. This paper explores efforts of a national K–12 school food collaborative to procure more sustainably grown and healthful food products. After a review of literature on transaction cost theory and school food procurement, the paper examines the potential of strategic partnerships in a value chain framework to meet procurement change goals. Results from a qualitative study of two participating school districts suggest that partnerships can offer potential solutions to recurring procurement barriers found in previous research.

In this paper we analyse the economic impact of alternative water management instruments that allow addressing the problem of non-renewable groundwater pumping in the aquifers of the Guadalentín Valley (southeast Spain). Their impact is assessed using a partial equilibrium mathematical programming model that maximises the farm net margin resulting from the use of the available water resources for irrigation in the area. Our results show that the buyback of groundwater pumping rights is the option with the greatest public budgetary cost and economic impact. On the contrary, the combination of an environmental tax on groundwater pumping and the substitution of groundwater by subsidised desalinised water allow eliminating aquifer overdraft in the area while...

Organic wheat farmers in Australia face a number of unique challenges, and an in-depth understanding of these challenges is an important first step for government agencies, universities and other groups interested in promoting organic agriculture. This research was designed to develop a qualitative understanding of the biggest transition, cultivation, market and other issues faced by organic wheat farmers in Australia. Data gathering was conducted with a series of one-to-one interviews. The top challenge identified was rain, water availability and soil moisture. This challenge places unique risks on organic farmers because of additional cultivation cycles and subsequent delayed seeding. A second key issue was weed management, with particularly tough issues...

Autores: Hatcher,   Sue; Johnson,   P.R.
This paper reviews the development of the wool follicle population with a view to the management of breeding ewes so as to optimise the genetic potential of the progeny for wool production and quality throughout their lifetime. It highlights the importance of the pre-weaning environment (i.e. maternal nutrition through pregnancy and lactation) on the initiation and maturation of the secondary follicle population and identifies the last third of pregnancy as the most critical period. The implications of this for the commercial wool producer are discussed in terms of matching the breeding cycle of the ewes to available pasture and provision of supplementary feed. Finally, it introduces a national project 'Lifetime Wool' funded by Australian Wool Innovation...

Directive 2009/28/EC established a common framework for the use, production and promotion of energy from renewable sources. Subsequently, each European Union Member State was required to prepare a national Renewable Energy Action Plan (REAP) which specifies the share of energy from renewable sources to be consumed in transport, as well as in the production of electricity and heating, in 2020. The Hungarian REAP was published in December 2010. In order to identify what further steps are required to meet the targets set by the REAP, in this article we review the current situation and the potential in Hungary for the production and use of biomass, biogas and biofuel. We conclude that the annual quantity of required biomass is already available and it should...

Is there Need for more Transparency and Efficiency in Cause‐related Marketing?
Provedor de dados: 31
Autores: Langen,   Nina; Grebitus,   Carola; Hartmann,   Monika.
The popularity of ethical consumption increases. This has motivated firms to increasingly implement Cause‐related Marketing (CrM) campaigns in Germany. But research reveals that especially German consumers are sceptic with regard to the amount of money spent for the good ‘cause’ by the enterprises. This can be explained by the small share of information provided by CrM campaigns to consumers. In consequence, this can reduce consumers’ willingness to purchase CrM products. Therefore, this study analyses whether the efficiency and transparency of a CrM campaign are important for consumers. The share of money reaching the cause relative to the product price consumers’ pay is taken as a proxy for efficiency while transparency is understood as the open...

Area response in wheat production: The Australian wheat-sheep zone
Provedor de dados: 31
Autores: Culas,   Richard J.
This paper investigates the key decision parameters of farmers related to the allocation of land between wheat production and pasture for sheep (wool) production. Wheat area supply response, is estimated across the Australian wheat-sheep zone using data for the period 1991 to 2004. Statistical results reveal that wheat growers in Western Australia are more price responsive than growers in the eastern states. Area adjustment is not significantly different between the regions. Rainfall has a positive influence on wheat production while time-related exogenous factors such as technical progress seemed to have little influence on the wheat yield over this period.

Impact Assessment of Bt Corn Adoption in the Philippines
Provedor de dados: 31
Autores: Mutuc,   Maria Erlinda M.; Rejesus,   Roderick M.; Pan,   Suwen; Yorobe,   Jose M., Jr.
This article examines the impact of Bt corn adoption in the Philippines using an econometric approach that addresses simultaneity, selection, and censoring problems. Although previous literature emphasizes the importance of simultaneity and selection problems, this is the first study that addresses the issue of censoring in estimating the effects of Bt corn adoption at the farm in a developing country context. We show that Bt corn adoption provides modest but statistically significant increases in farm yields and profits. Furthermore, our results provide some evidence of inference errors that can potentially arise when censoring in the pesticide application variable is ignored in the estimation procedures.

Tanulmányunkban az ökoélelmiszerek fogyasztói megítélését, a fogyasztói szokásokat és azokat befolyásoló tényezőket mutatjuk be. Az 1200 fős primer megkérdezés eredményei szerint a fogyasztók az ökoélelmiszerekről egyre bővebb ismeretekkel rendelkeznek, felismerik és keresik őket. A vegyszermentességük és természetességük miatt ezeket a termékeket az egészségre kedvező hatásúnak tartják.  A magas ár azonban még mindig korlátot jelent, az értékarányos ár elfogadásához több tájékoztatás és erőteljesebb kommunikáció szükséges.  Az ökotermékek értékesítésekor rendkívül fontos a bizalom, amely egyrészt az eladó és a vevő közvetlen kapcsolatának erősítésével, másrészt a minősítési rendszer szigorúságával garantálható.  --------------------------------------- In...

Causes of farm diversification over time: an Australian perspective on an Eastern Norway model
Provedor de dados: 31
Autores: Culas,   Richard J.
Farm planning often focuses on optimal diversification with respect to risk, where the risk-management strategies combine production, marketing, financial and environmental aspects of the farm-firm. In this study an empirical examination of diversification has been carried out using a sample of farms in Eastern Norway. Four measures of diversification (indices) were defined to record the risks in relation to income from farm production. Using these alternative measures of diversification and panel-data, the results show that larger farms are more diversified, and for farms in more favourable locations and access to labour, the farmers have a greater incentive to spread risk. These results suggest that diversification and farm size are positively linked and...

The current state of Contract Law in Australia and why it is important for rural managers to understand it
Provedor de dados: 31
Autores: Smith,   Tony.
Farmers are business managers and as such they must understand the law or they are likely to fall foul of it. This especially applies to contract law, with which they deal constantly. Contract law is made up of the common law – as the courts have decided it – and statute law- as the state and federal parliaments have enacted statutes which modify the common law. The most important and most recent of the latter is the new Australian Consumer Law.

Using a completely randomised design, three experimental groups and a control group of lactating meat ewes, i.e. Cuban Pelibuey breed, were exposed to supplementary feeding of Leucaena leucocephala with 1.50, 1.25 and 1.0 kg of green stuff. Body weight, corporal condition and biochemical blood indicators (i.e. haemoglobin, glucose, total blood protein, albumin and urea) were monitored at different times. Ewes from the group with the highest level of legume tree consumption achieved higher body weight, excellent corporal condition and normal biochemistry blood indicators compared to the remaining experimental groups. The two experimental groups with higher legume tree supply achieved faster reproductive cycle performance. An ANOVA test confirmed the...

Dynamic general equilibrium analysis of improved weed management in Australia's winter cropping systems
Provedor de dados: 31
Autores: Wittwer,   Glyn; Vere,   David T.; Jones,   Randall E.; Griffith,   Garry R.
A recent analysis indicated that the direct financial cost of weeds to Australia’s winter grain sectorwas approximately $A1.2bn in 1998–1999. Costs of thismagnitude represent a large recurring productivity loss in an agricultural sector that is sufficient to impact significantly on regional economies.Using amulti-regional dynamic computable general equilibrium model, we simulate the general equilibrium effects of a hypothetical successful campaign to reduce the economic costs of weeds. We assume that an additional $50m of R&amp;D spread over five years is targeted at reducing the additional costs and reduced yields arising from weeds in various broadacre crops. Following this R&amp;D effort, one-tenth of the losses arising from weeds is temporarily...

The Blinder–Oaxaca decomposition for nonlinear regression models
Provedor de dados: 31
Autores: Sinning,   Mathias; Hahn,   Markus; Bauer,   Thomas K.
In this article, a general Blinder–Oaxaca decomposition for nonlinear models is derived, which allows the difference in an outcome variable between two groups to be decomposed into several components. We show how, using nldecompose, this general decomposition can be applied to different models with discrete and limited dependent variables. We further demonstrate how the standard errors of the estimated components can be calculated by using Stata's bootstrap command as a prefix.

Food policy and poverty in Indonesia: a general equilibrium analysis
Provedor de dados: 31
Autores: Warr,   Peter G.
Rice is Indonesia’s staple food and accounts for large shares of both consumers’ budgets and total employment. Until recently, Indonesia was the world’s largest importer, but rice import policy is now highly protectionist. Since early 2004, rice imports have been officially banned. Advocates of this policy say it reduces poverty by assisting poor farmers. Opponents say it increases poverty, stressing negative effects on poor consumers. This paper uses a general equilibrium model of the Indonesian economy to analyse the effects of a ban on rice imports. The analysis recognises 1000 individual households, including allmajor socioeconomic categories, disaggregated by expenditures per person. It takes account of effects on each household’s real expenditure and...

Analysis of Factors Influencing Development of Resource-saving and Environment-friendly Agriculture in China
Provedor de dados: 31
Autores: Gao,   Wen; Luo,   Min.
By selecting the data from 1989 to 2009 in China, we conduct regression analysis on the total out value of agriculture, the usage amount of chemical fertilizer, total power of agricultural machinery, effective irrigation area, and the damage area. The results show that the usage amount of chemical fertilizer and the damage area, the great obstacle to the construction of resource-saving and environment-friendly agriculture, have significant impact on the output value of agriculture; total power of agricultural machinery and effective irrigation area have insignificant impact on the output value of agriculture. Based on these, the suggestions for promoting the development of resource-saving and environment-friendly agriculture are put forward as follows:...

Organic dairy farming: cost of production and profitability
Provedor de dados: 31
Autores: Shadbolt,   Nicola M.; Kelly,   Terry; Holmes,   Colin.
Organic milk production in the European Union (EU) costs more than conventional production and therefore requires a price premium (15-25%) and an increase in direct payments to ensure the same level of profitability. In European comparisons, milk yields per cow are lower (9-30%) and stocking rates are also 20-40% lower due to lower yields in forage production. The International Farm Comparison Network (IFCN 2003), comparison between organic and non-organic farms in the EU calculated 22-37% higher costs of production. Similarly the cost increase measured in California ranged from 13-23% for organic versus conventional milk production. However comparisons between low producing and low cost systems as described by MafPolicy (2002), and for the Argentinean...

Higher Carbon Prices Could Spur Adoption of Methane Digesters
Provedor de dados: 31
Autores: Key,   Nigel D.; Sneeringer,   Stacy E.
A market price for carbon emission reductions would allow livestock producers with methane digesters to earn additional revenue from trapping and burning methane from manure. Greater income from reducing methane emissions could substantially increase the number of livestock producers who would find it profitable to install methane digesters. Large-scale hog and dairy operations with lagoon manure management systems are likely to benefit most from a higher carbon price, which could have longrun structural implications for the livestock sector.

Bovine spongiform encephalopathy in Japan: consumers’ food safety perceptions and willingness to pay for tested beef
Provedor de dados: 31
Autores: McCluskey,   Jill J.; Grimsrud,   Kristine M.; Ouchi,   Hiromi; Wahl,   Thomas I.
The discovery of bovine spongiform encephalopathy (BSE), commonly known as ‘mad cow disease’, in Japan caused anxiety about consuming beef and beef products. As a result, there was a sudden fall in sales of beef that hurt the Japanese beef industry as well as major beef exporters to Japan. We analyse factors that affect Japanese consumers’ willingness to pay (WTP) price premiums for BSE-tested beef and estimate the mean WTP for BSE-tested beef using data obtained from a consumer survey in Japan. A single-bounded dichotomous choice contingent valuation model is used to recover the premium amount. We find that attitudes to food safety, reduction in beef consumption following the BSE outbreak, and being female all have a statistically significant positive...

This study shows the impact of cropping intensity on the economic results of plant production in Poland. The real amount of production outlays, which in value terms represents the level of direct costs, was adopted as the intensity measure. The economic results diversification scale is reflected by the level of gross margin and income from management activity, as well as by the production profitability index in the activity types analysed. When using low-intensity, as compared to high-intensity, cropping technologies, the economic results of the activities in question become more favourable. The profitability analysis of various production factors points to a prevalence of agricultural farms with low intensity levels of the activity conducted. Lower...

Developing decision-making tools for improving pasture quality on deer farms in New Zealand
Provedor de dados: 31
Autores: Stevens,   David R.; Woodward,   Simon J.R.; Westbrooke,   Victoria F.C.
This paper describes the development of a learning package to support improved pasture quality on New Zealand deer farms. The first step has been to determine the specific requirements of deer farmers that will enable them to improve pasture quality decisions on-farm. Decision support software that interprets and demonstrates the impacts of pasture quality and animal physiology on the performance of young growing deer has also been developed. Key themes identified to aid pasture management decision-making included identifying the right pasture quality, management systems to maintain pasture quality and maximising the potential of livestock. This paper reports on the type of knowledge that deer farmers require in the learning package.

The study investigates the convergence of labour productivity in 204 NUTS2 regions of the EU-15 between 1995 and 2006. The main objective of our work was to assess whether and to what extent European Union (EU) policies (Regional Policy and Common Agricultural Policy) have been effective in promoting economic growth and fostering the process of convergence of EU regions. These policies can have an asymmetric spatial impact, even if some concrete steps have been taken to avoid an excessive concentration of costs or benefits. To verify the effects of EU policies we compare different scenarios: with/without EU policies. Under a methodological profile, we adopt the Solovian model proposed by Mankiw et al. (1992).

The introduction of a carbon price and the use of agrichar in the sugarcane industry
Provedor de dados: 31
Autores: Thomas,   Cameron.
The Australian Government‘s proposal to put a price on carbon is likely to have a significant impact on the price of farm inputs (diesel, fertiliser, water and electricity). Furthermore, offsets (reduction or removal of greenhouse gas emissions that counterbalances emissions elsewhere in the economy) are a potential area of expansion of interest to the agricultural sector. Agrichar is one of the new technologies and farming practices being investigated to counteract carbon-price-imposed costs. Its two claimed benefits, which relate both to the profitability of sugarcane growers as well as to climate change, are the reduction in fertiliser application and the carbon which agrichar can store in the soil for hundreds to thousands of years. This study drew on...

Farm systems in Australia are open systems. The financial openness of farm systems has implications for managing farms and, thus, implications for analysing farm management decisions and farm performance. In elaborating on this theme, capital investment in agriculture is considered and key ideas about agricultural financing and implications for farm management are identified. Focussing on the economics of farm management analysis, without corresponding equivalent attention to finance, is to do half the job.

Land reform and farm performance in Europe and Central Asia: a 20 year perspective
Provedor de dados: 31
Autores: Lerman,   Zvi.
The rural sector in nearly all the countries of Central and Eastern Europe (CEE) and the Commonwealth of Independent States (CIS) has undergone a shift from predominantly collective to more individualized agriculture. At the same time, most of the land in the region has shifted from state to private ownership. These two shifts – a shift in tenure and a shift in ownership – were part of the transition from a centrally planned economy to a more marketoriented economy that began around 1990 in the huge post-Soviet space stretching from Prague to Vladivostok. The transition reforms in the region were unprecedented in their scope and pace. Some 150 million hectares of agricultural land transferred ownership in these countries in just one decade of reform...

Conceptualising ‘macro-regions’: Viewpoints and tools beyond NUTS classification
Provedor de dados: 31
Autores: Ladias,   Christos; Hasanagas,   Nikolaos; Papadopoulou,   Eleni.
Definitions are imposed but properties not. The basic question addressed by this paper is how to ‘detect’ objective socio-economic spatial structures instead of ‘defining’ them arbitrarily. The NUTS classification model is rather arbitrary. Not only have the administrative units been structured through ‘accidental’ historical conditions but the reliability of the measurement of the population in an area is disputable as long as the mobility is strengthened and the ‘usual residence’ becomes more and more vague. Concerning the auxiliary criteria, they are also heterogeneous and are rather perceptions imposed by decision makers than physical entities. The quantitative network analysis (QNA) approach is suggested as a tool to detect macro-structures regarded...

We employ a heavily modified ‘agricultural’ variant of the GTAP model and a realistic baseline scenario to assess the impact on the Greek economy from a hypothetical ‘hub and spoke’ and a ‘FTA’ EUMED agro-food and fisheries trade agreement. Long run estimates show that Greek agro-food and fisheries sectors are not seriously affected, where surprisingly, trade diversionary losses to Greece from the FTA scenario are minor given minimal south-south trade links between Mediterranean Partner Countries (MPC). Further research shows that under complete CAP decoupling, notable additional welfare gains for MPC are realised, whilst Greece stands to lose approximately €300 million.

The receiver operating characteristic (ROC) curve displays the capacity of a marker or diagnostic test to discriminate between two groups of subjects, cases versus controls. We present a comprehensive suite of Stata commands for performing ROC analysis. Nonparametric, semiparametric, and parametric estimators are calculated. Comparisons between curves are based on the area or partial area under the ROC curve. Alternatively, pointwise comparisons between ROC curves or inverse ROC curves can be made. We describe options to adjust these analyses for covariates and to perform ROC regression in a companion article. We use a unified framework by representing the ROC curve as the distribution of the marker in cases where we have standardized it to the control...

Production Performance and Economic Appraisal of Broiler Farms in Anand District of Gujarat
Provedor de dados: 31
Autores: Shaikh,   A.S.; Zala,   Y.C.
The production performance of different sizes of broiler farms has been studied by collecting data from 60 broiler producers of Anand district during 2005. To examine production performance, the average feed conversion ratio, livability percentage, average body weight and age at marketing have been worked out. Though broiler production is capital-intensive, it has been found profitable. The average cost of production per broiler has been found to be ` 64 and per kilogram live weight of broiler as ` 32. The variable cost and fixed cost constitute 84.5 per cent and 15.5 per cent of total cost, respectively. The major cost components have been found as feed cost (58.6%), chick cost (21.5%) and depreciation on buildings (10.7%). The net profit per broiler as...

Rural Employment Diversification in India: Trends, Determinants and Implications on Poverty
Provedor de dados: 31
Autores: Kumar,   Anjani; Kumar,   Sant; Singh,   Dhiraj Kumar; Shivjee.
This paper has studied rural employment diversification in India and across major states using NSSO data at household level for the period 1983 and 2009-10. Factors affecting rural employment diversification towards non-farm sector have also been studied. Analysis has shown that the non-farm sector has consistently grown over time and employed nearly one-third of the rural workforce in 2009-10, as compared to merely one-fifth in 1983 at all-India level. The similar trend is seen across major states as well, though the pace and pattern varied widely. In providing employment to rural workforce, increasing dominance of crop production, followed by animal husbandry was observed across major states during 2009-10. The share of fishery and forestry was...

A snapshot of Western Balkan’s agriculture from the perspective of EU accession
Provedor de dados: 31
Autores: Mizik,   Tamas.
The Western Balkan countries can be characterised by their shared goal, which is rapid accession to the EU. Agriculture is an important element to achieving this goal. The role of agriculture differs widely among the analysed countries but is more important than the average of the EU. This study gives a comprehensive overview of the most important agricultural indicators. These indicators give a precise picture of the sector’s relevance, production structure, efficiency and international relations. After demonstrating changes in input use, production structure, prices and agricultural policies, the next section identifies some of its reasons. The analysis concentrates on the newest available data. Serbia is the leading producer and the only net exporter of...

Feature, "The NAFTA Countries Build on Free Trade"
Provedor de dados: 31
Autores: Zahniser,   Steven.
Free trade is deeply rooted within North America’s agricultural economy. Canada, Mexico, and the United States gradually removed thousands of barriers to regional agricultural trade from 1994 to 2008 as part of the North American Free Trade Agreement (NAFTA). From 1989 to 1993, Canada and the United States pursued agricultural trade liberalization through the Canada-U.S. Free Trade Agreement (CUSTA), which was then folded into NAFTA. Mexico also implemented a number of unilateral agricultural trade reforms in the early 1990s. When these initiatives are considered together, the NAFTA countries have completed a remarkable two decades of agricultural trade liberalization.

Production function estimation in Stata using the Olley and Pakes method
Provedor de dados: 31
Autores: Yasar,   Mahmut; Raciborski,   Rafal; Poi,   Brian P.
Productivity is often computed by approximating the weighted sum of the inputs from the estimation of the Cobb–Douglas production function. Such estimates, however, may suffer from simultaneity and selection biases. Olley and Pakes (1996, Econometrica 64: 1263–1297) introduced a semiparametric method that allows us to estimate the production function parameters consistently and thus obtain reliable productivity measures by controlling for such biases. This study first reviews this method and then introduces a Stata command to implement it. We show that when simultaneity and selection biases are not controlled for, the coefficients for the variable inputs are biased upward and the coefficients for the fixed inputs are biased downward.

Autores: Painter,   Marvin J.
This study shows that for the period 1990–2007, international portfolio investment performance was significantly improved with the addition of Canadian farmland. Farmland in Canada is considered relatively low risk, enters the efficient portfolios at low risk levels and adds the most financial improvement to low and medium risk portfolios. Compared with T-bills and long bonds, farmland has higher risk and yield, but lower risk than stocks. Compared with stocks, farmland has income yields and risk that are similar to or better than dividend yields and risk on stocks while farmland has capital gain yields and risk that are usually lower, on average, than stocks. The low and negative correlation of farmland yields with stocks and bonds make it a good...

When the Seasonal Foreign Farm Workers are Gone
Provedor de dados: 31
Autores: Escalante,   Cesar L.; Perkins,   Samuel L.; Santos,   Florence Ivy M.
When seasonal foreign farm workers with illegal resident status have left the country, farms experience difficulty in finding “motivated” equally efficient workers to fill in the void. This study’s survey and case study indicate that larger conventional farms usually opt for greater mechanization of their operations, with downsizing as another remedy. These farms also rely heavily on family members’ increased involvement in farm management. Enterprise budget analysis results suggest that when family farm labor inputs are exhausted, business losses could be realized, as yields are significantly reduced due to difficulty or delay in hiring domestic unskilled workers.

Autores: Maheshwari,   M. Selva; Gangwar,   L.S.
This study conducted in the Thanjavur district of Tamil Nadu, has indentified the problems being faced by dairy farmers due to scarcity of farm labour for agricultural and livestock production. The study is based on the data collected from 40 selected respondents involved in crop production and dairying in the study area during the year 2008-09 through primary survey. The study has revealed that the implementation of Mahatma Gandhi National Rural Employment Guarantee Scheme (MGNREGS) has provided employment opportunities to rural workers and has checked the migration of farm labour from villages to cities and nearby industrial townships. All the eligible family member of landless dairy farmers had the job cards, but medium and large dairy farmers...

Autores: Orsini,   Nicola; Bellocco,   Rino; Bottai,   Matteo; Wolk,   Alicja; Greenland,   Sander.
Classification errors, selection bias, and uncontrolled confounders are likely to be present in most epidemiologic studies, but the uncertainty introduced by these types of biases is seldom quantified. The authors present a simple yet easy-to-use Stata command to adjust the relative risk for exposure misclassification, selection bias, and an unmeasured confounder. This command implements both deterministic and probabilistic sensitivity analysis. It allows the user to specify a variety of probability distributions for the bias parameters, which are used to simulate distributions for the bias-adjusted exposure–disease relative risk. We illustrate the command by applying it to a case–control study of occupational resin exposure and lung-cancer deaths. By...

This study analyzed the Brazilian coffee exporter’s losses between the years 2002 and 2009, by emphasizing the 2007/09 crisis, which affected several sectors and generated instability and uncertainty about the future results of the economic activities. The Brazilian coffee exporting sector is fully inserted in this context, once it acts in the financial markets and it is still subject to the strong variations from the physical market. Thus, the central analysis dealt with the volatility of the exporters returns and was based on auto regressive models with conditional heteroscedaticity (ARCH) and on the Value at Risk (VAR) estimative. As a supplement, the effects from the external demand for the Brazilian coffee and from the exchange rate variation over the...

Multivariable modeling with cubic regression splines: A principled approach
Provedor de dados: 31
Autores: Royston,   Patrick; Sauerbrei,   Willi.
Spline functions provide a useful and flexible basis for modeling relationships with continuous predictors. However, to limit instability and provide sensible regression models in the multivariable setting, a principled approach to model selection and function estimation is important. Here the multivariable fractional polynomials approach to model building is transferred to regression splines. The essential features are specifying a maximum acceptable complexity for each continuous function and applying a closed-test approach to each continuous predictor to simplify the model where possible. Important adjuncts are an initial choice of scale for continuous predictors (linear or logarithmic), which often helps one to generate realistic, parsimonious final...

Modelling a mixed system of air pollution fee and tradable permits for controlling nitrogen oxide: a case study of Taiwan
Provedor de dados: 31
Autores: Liao,   Chao-Ning.
A mixed-integer non-linear programming model that minimises the total regulatory costs of controlling nitrogen oxide is used to investigate how a newly proposed permit trading scheme in Taiwan, which incorporates the features of banking and a nonone- to-one trading ratio, may affect firms’ emission reduction strategies and permit trading decisions. Compared to the previous regulation where only an air pollution fee is used, the new regulation that requires a reduction in emissions by 10 per cent from the emission level in the year 2000 for a 5 year period will increase the costs by 77 per cent, which is equivalent to US # 9.87 million. The design of banking and the increasing returns to scale characteristic of pollution control among firms might lead to an...

An Empirical Investigation of the Linkages between Government Payments and Farmland Leasing Arrangements
Provedor de dados: 31
Autores: Qiu,   Feng; Goodwin,   Barry K.; Gervais,   Jean-Philippe.
This article investigates the impacts of decoupled and coupled program payments on farmland rental contract choices for a subset of U.S. crop farms using a principal-agent model.We consider cash and share contracts as well as hybrid contracts, which represent an increasingly prominent feature of U.S. agriculture. The conceptual framework suggests that restrictions on payments between contracting parties are ineffective and induce an offsetting contractual rearrangement. Empirical results from a multinomial logit model confirm that government support programs have large, significant effects on contract choices and that these effects vary by types of programs.

Data Availability for Carbon Calculators in Measuring GHG Emissions Produced by the Food Sector
Provedor de dados: 31

The continuing increase in burning fossil fuels over recent decades along with the changing land use have resulted in a considerable increase in the amount of greenhouse gases (GHGs) which can potentially lead to climate change. Adaptation processes will become necessary in order to cope with these challenges in the future. Despite individuals’ and institutions’ willingness to reduce the amount of GHG emissions caused by their actions or their “carbon footprints”, they may lack the knowledge to make effective choices. Carbon calculators have been developed to address these knowledge gaps by measuring and communicating the overall magnitude of the impacts and also the extent to which different behavior patterns contribute to GHG emissions.

The labour scarcity being felt as a major impediment in agriculture, this study has probed into its magnitude, impacts, causes and possible solutions in the Cuddalore district of Tamil Nadu. The study has revealed that prevalence of acute labour scarcity in the district has affected the productivity levels of almost all crops and is even leading towards the permanent changes in the cropping pattern. The important reasons identified for the labour scarcity include higher wages in other locally-available jobs, seasonal nature of agricultural jobs and presumption of an agricultural job to be of low esteem. The level of adoption of labour-saving implements and technologies by the farmers is very low for the reasons of higher cost, lack of skill and smaller...

Parallels are drawn between shortcomings and events that occurred in our western heritage with current issues facing agricultural economists. Challenges are made in relation to conflict of interest policies, external funding, cultivating connections with experts outside our discipline, and relevance of research priorities. Survey data on research priorities of upper administrators and faculty within colleges of agriculture are compared to those of Western Agricultural Economics Association members. Upper administrators from land grant colleges rank research focused in the area of competitiveness and profitability less than areas of water usage, food safety, renewable energy, global climate change, or sustainability.

To study which method is more effective in complete compensation and zero compensation for rural land expropriation, we use economic models to analyze whether the government is benevolent and which compensation method can achieve the social optimal level. The results show that both complete compensation and zero compensation will lead to over-investment of land owners, and consequently result in loss of social welfare.

Because only a small share of production enters the global market, the world rice market remains susceptible to substantial price volatility. Price volatility is exacerbated by trade policies of importers and exporters seeking to protect their consumers from high prices and ensure adequate supplies. For the U.S., this price and trade volatility can translate into short-term export opportunities.

Comparative analysis of different tillage systems used in sugarcane (Thailand)
Provedor de dados: 31
Autores: Grange,   Ian; Prammanee,   P.; Prasertsak,   P.
In order to reduce the impact of decreasing profit margins in crop production systems, all possible options that will increase net profits need to be explored. Land preparation and stool removal in sugarcane production can be a major contributor to overall production costs. Since estimates that mechanization can contribute as much as 50% of the total production costs, considerable savings can potentially be made if the number of tillage operations is reduced. Such savings however, have to be offset against other costs associated with minimum or no-tillage systems, such as the increased need for herbicide. In addition, conventional tillage systems have been implicated in yield decline over the long-term and therefore yield benefits are envisaged, together...

Dynamic Relation between Rural Human Capital and Farmers' Income in Henan Province
Provedor de dados: 31
Autores: Li,   Ting-ting; Zhang,   An-liang.
We use relevant economic and labor force data from 1990 to 2009 of Henan Province to analyze the dynamic relation between stock of rural human capital and farmers' income. Results indicate that a certain causal relationship and long-run equilibrium relation exist between rural human capital and farmers' income, but their interaction shows some lagging characteristic. Increase of farmers' income in Henan Province increases the stock of rural human capital in this Province for a short term. However, in the long run, this accumulation effect will decline along with renewal and aging of knowledge. The positive promotion action of rural human capital on farmers' income will appear after a long lag time. therefore, the policy of strengthening rural human capital...

Former Soviet Union Region To Play Larger Role in Meeting World Wheat Needs
Provedor de dados: 31
Autores: Liefert,   William M.; Liefert,   Olga; Vocke,   Gary; Allen,   Edward W.
By 2019, Russia could become the world’s top wheat exporter, and Russian, Ukrainian, and Kazakhstan wheat exports collectively could more than double those of the United States. Growth in the former Soviet Union’s grain production and exports may increase world food availability and, in the near term, help mitigate global food security concerns. U.S. wheat production is leveling off, as U.S. producers shift acreage to benefit from competitive advantages in corn and soybeans.

Autores: Heizler,   Odelia; Kimhi,   Ayal.
This paper analyzes the effect of family composition, and in particular the number of children, the age gap between the oldest and youngest child and the age of the youngest child, on parents’ involvement in social networks. The predictions of a simple theoretical model are confirmed by an empirical analysis of Israeli Social Survey data for 2002- 2006. The number of children has a U -shaped effect on parents' involvement in social networks, with substantial differences between fathers and mothers. The negative effect is dominant on the mothers’ involvement in social networks, while the positive effect is dominant on the father's involvement in social networks. The age gap between children has a positive effect on both parents’ involvement in social...

“A Definition at Last, But What Does it All Mean?” Newspaper Coverage of Organic Food Production and its Effects on Milk Purchases
Provedor de dados: 31
Autores: Kiesel,   Kristin.
This paper estimates the effects of media coverage of organic food production on food purchases. Information from several data sources links national and local newspaper coverage to fluid milk purchases. An analysis of weekly store-level scanner data in a differences-in-differences approach results in a 5% increase in organic milk sales relative to conventional milk sales. Increases in intensity of news coverage increase this relative difference in sales. Differentiating effects by media context further suggests that product category specific coverage increases sales more than general coverage. Critical coverage does not result in significant effects on organic milk sales.

Ennek jogi pillére olyan alkotmányos intézmény lehet, amely a Magyar Állam területét alkotó termőföldet tulajdoni formájától függetlenül a nemzet vagyonának minősíti. Az állam az államterületét alkotó, földre fennálló alkotmányos önrendelkezési joga alapján valamennyi jogalanyra kiterjedően szabályozza és közérdekből korlátozhatja a termőföld-tulajdonszerzés és a földhasználat feltételeit.

Forage plus Grain Wheat versus Grain-Only Wheat
Provedor de dados: 31
Autores: Duke,   Jason C.; Epplin,   Francis M.; Vitale,   Jeffrey D.; Peel,   Derrell S.
Winter wheat may be grown in the Southern Plains either to produce grain only, or as a dual-purpose crop to produce both fall-winter forage and grain. The objective of the research is to determine expected net returns for both production systems. The estimated expected net value of the dualpurpose system stocked with steers with an initial weight of 450 pounds is from $38 to $92 per acre greater than that of the grain-only system. The economic success of dual-purpose wheat depends on a number of management factors including stocking density.

Network Experiences Lead to the Adaption of a Firm’s Network Competence
Provedor de dados: 31
Autores: Kuhne,   Bianka; Cochez,   Carl; Gellynck,   Xavier.
Networks become increasingly important as external sources of innovation for firms. Through networks firms get in contact with different actors with whom they can exchange information and collaborate. A firm’s ability to be a successful network actor depends on its network competence. This term can be defined as having the necessary knowledge, skills and qualifications for networking as well as using them effectively. In this paper we investigate the link between a firm’s network competence and the benefits resulting from it in a two-way direction. First, the network competence of the firm facilitates the adoption of information from other network actors which may lead to innovation success. Second the perceived network benefits shall in their turn...

Perceived Traceability Costs and Benefits in the Italian Fisheries Supply Chain
Provedor de dados: 31
Autores: Asioli,   Daniele; Boecker,   Andreas; Canavari,   Maurizio.
The paper proposes a model in which it is hypothesized that firm characteristics influence both costs and benefits of traceability. The proposed model differentiates between aggregate measures and specific categories, as well as between expected costs and benefits on the one hand and perceived actual outcomes on the other, and is tested in a series of regression analyses based on a survey sample of 60 Italian fish processors. The findings indicate that firm characteristics are not strongly associated with any specific cost or benefit measure. However, expected overall benefits are highly significantly impacted by firm size and the number of quality management systems certified, while actual overall benefits only by firm size. Finally, the study also finds...

Optimal management of a flammable forest providing timber and carbon sequestration benefits: an Australian case study
Provedor de dados: 31
Autores: Spring,   Daniel; Kennedy,   John O.S.; Mac Nally,   Ralph.
In deciding to keep or fell a forest stand given its age, the risk of loss of timber through wildfire is an important consideration. If trees also have value from sequestration of carbon, another effect of fire is the unplanned loss of stored carbon. Factors affecting the decision to keep or fell trees, and how much to spend on fire protection, are investigated using stochastic dynamic programming, using carbon sequestration in stands of mountain ash in Victoria as a case study. The effect of treating sawlogs as a permanent carbon sink after harvesting is explored.

A new set of tools is described for performing analyses of an ensemble of datasets that includes multiple copies of the original data with imputations of missing values, as required for the method of multiple imputation. The tools replace those originally developed by the authors. They are based on a simple data management paradigm in which the imputed datasets are all stored along with the original data in a single dataset with a vertically stacked format, as proposed by Royston in his ice and micombine commands. Stacking into a single dataset simplifies the management of the imputed datasets compared with storing them individually. Analysis and manipulation of the stacked datasets is performed with a new prefix command, mim, which can accommodate data...

The nature and extent of crop diversification in the Karnataka state has been analyzed by collecting secondary data for a period of 26 years from 1982-83 to 2007-08. Composite Entropy Index (CEI) and multiple linear regression analysis have been used to analyze the nature and extent of crop diversification in the state. The CEI for different crop groups has shown that almost all the crop groups have higher crop diversification index during post-WTO (1995-96 to 2007-08) than during pre-WTO (1982-83 to 1994-95) period, except for oilseeds and vegetable crops. There has been a vast increase in diversification of commercial crops after WTO. Crop diversification is influenced by a number of infrastructural and technological factors. The results have revealed...

There has been increased public demand for environment protection, including in rural areas. Government programs and policies have responded to these demands in various ways, such as by attempting to increase farmer awareness of environmental issues, increasing budgets for rural environmental programs, increasing environmental regulation, purchasing water from irrigators for environmental purposes, and encouraging farmer adoption of new environmentally friendly practices. These changes create a number of challenges for farmers, including challenges related to maintaining farm productivity, meeting community expectations, living with less water and evaluating new opportunities. These challenges are described and discussed. While there certainly are...

Demographic and Management Factors Affecting the Adoption and Perceived Yield Benefit of Winter Cover Crops in the Southeast
Provedor de dados: 31
Autores: Bergtold,   Jason S.; Duffy,   Patricia A.; Hite,   Diane; Raper,   Randy L.
The inclusion of cover crops in cropping systems brings direct and indirect costs and benefits. Farmers will adopt and utilize cover crops as long as the perceived benefit of using them is positive. This paper examines the demographic and management factors affecting the adoption and perceived benefit (in terms of improved crop yield) of using winter annual cover crops. A double selectivity model of cover crop adoption and perceived yield gain was estimated using survey data of Alabama farmers examining cover crop use and management.  Results may help in understanding factors shaping farmers’ perceptions, adoption, and retention of cover crops.

California farm managers and rural appraisers were surveyed in Fall 2009 to rank the importance of several skills pertaining to their profession. Additional questions included age, income, years of experience, professional designations and affiliations, and whether the Valuation Code of Conduct (VCC) had affected their appraisal activities. On average, California rural appraisers were 52 years old, over half had incomes of $100,000 or greater, and the VCC has had little impact on their practice. Similar to previous studies, communication skills are thought more important than personal or technical skills.

This study has evaluated the impact of MGNREGA on income generation and labour supply in agriculture in one of the districts in central dry zone of Karnataka. Results have shown that the number of days worked in a year with the implementation of MGNREGA programme has significantly increased to 201 days, reflecting 16 per cent increase. Regression analysis has revealed that gender, education and family size of the workers are the significant factors influencing the worker’s employment under the Program. The increase in income is to the tune of 9.04 per cent due to additional employment generated from MGNERGA. In the total income, the contribution of agriculture is the highest (63%), followed by non-agricultural income (29%) and MGNREGA income (8%)....

Economic Impacts of Zilmax(R)  Adoption in Cattle Feeding
Provedor de dados: 31
Autores: Schroeder,   Ted C.; Tonsor,   Glynn T.
The Food and Drug Administration recently approved the feeding of Zilmax(R) for cattle in the United States. This study determines direct net return benefits for early-adopting cattle feeders and beef packers. In addition, longer-run producer and consumer surplus measures are estimated as adoption impacts market prices and quantities. After markets adjust, cow-calf producers, cattle feeders, and consumers will gain from adopting the new technology.

Autores: Cox,   Nicholas J.
The count command has one simple role, to count observations in general or that satisfy some condition(s). This task can be useful when some larger problem pivots on counting, especially if count is used with a loop over observations or variables. I use various problems, mostly of data management, as examples. I also make comparisons with the use of _N, summarize, and egen for the same or similar problems.

The SURE Program and Its Interaction with Other Federal Farm Programs
Provedor de dados: 31
Autores: Ubilava,   David; Barnett,   Barry J.; Coble,   Keith H.; Harri,   Ardian.
We investigate potential effects of the Supplemental Revenue Assistance Payments (SURE) program introduced in the 2008 Farm Bill. Results suggest little impact on optimal crop insurance purchase decisions, though the SURE program does seem to provide an incentive for mid-level insurance coverage. For producers in the price counter-cyclical payment (PCCP) program, SURE payments are actually higher (lower) when commodity prices are high (low). This is not the case for producers in the Average Crop Revenue Election (ACRE) program.

Irrigation water pricing between governmental policies and farmers’ perception: Implications for green-houses horticultural production in Teboulba (Tunisia)
Provedor de dados: 31
Autores: Chebil,   Ali; Frija,   Aymen; Thabet,   Chokri.
A positive mathematical programming model was constructed in this study to assess the effect of three water pricing scenarios on Teboulba’s agricultural production systems. The effects of these scenarios were estimated for three groups of farmers from three irrigated districts. Results show that water demand in group 1 remains inelastic until achieving the price of 0.20 TD. A price above this level decreases water consumption, farmer’s incomes as well as seasonal labor demand. For groups 2 and 3, the water demand curves remain highly inelastic even with a full cost recovery price. However, once reaching this last price, the model shows important income reductions reaching 20% of the current observed income. Moreover, a pricing policy aiming to recover...

Where's the economics? The core discipline of farm management has gone missing!
Provedor de dados: 31
Autores: Malcolm,   Bill.
Economic illiteracy is abundant in farm management analysis. Failure to understand that economics is the core discipline of farm-management analysis and failure to apply the whole-farm approach leads to wrong questions being asked and wrong answers being given. The power of economic thinking is in making sense of resource allocation questions in farm systems characterised by much complexity and powerful dynamics. The challenge for those who continue to work in farm management economics is to re-establish theoretically sound farm-management analysis based on economics as the core discipline.

An exploration of language for biodiversity and regeneration in Australian agriculture
Provedor de dados: 31
Autores: Scott,   Pennie; Watson,   Geoff K.
The language of words is the most commonly used tool in person to person communication and this in turn, profoundly reflects and creates an individual’s belief systems and behaviours. In the arena of sustainable production systems for food and fibre and the ‘management’ of natural resources, there is a plethora of information provided by organisations dedicated to researching and communicating new land use methods for farmers to implement. However to date, the uptake of new methods has been frustratingly low resulting in the on-going degradation of Australia’s fragile landscapes while exploitative farming practices continue. A key issue is whether the language of current policies is appropriate to influence the belief systems of decision makers in...

This study evaluates all USDA cotton supply and demand estimates for the United States and China (including unpublished price forecasts) from 1985/86 through 2009/10 for accuracy and efficiency. Results reveal that at every stage of the forecasting cycle forecast smoothing was the most widespread and persistent type of inefficiency observed in most U.S. variables. Correlation with past errors indicated the tendency to repeat past errors in most cases. Tendency to overestimate growth was also found. Bias was uncommon and limited to several cases of overestimation of China’s exports and U.S. price and underestimation of China’s domestic use. While forecasts of China’s imports and endings stocks improved, U.S. price and ending stock forecast errors became...

A comparison of hypothetical survey rankings with consumer shopping behavior and product knowledge
Provedor de dados: 31
Autores: Grebitus,   Carola; Colson,   Gregory; Menapace,   Luisa.
Hypothetical surveys are commonly used to elicit consumer behavior to guide product development, marketing, and labeling strategies. However, despite the prevalence of surveys in consumer food studies, previous work has not assessed the relationship between hypothetical responses and actual consumer behavior in real-world purchase situations.We explore whether attributes cited by consumers in surveys as being important to them when making decisions indeed factor into their product decision process in real-world markets. Evidence from a point of sale study of 702 pork purchasers indicates that there is a strong correspondence between hypothetical survey ratings and actual shopping behavior.

Outcomes of the SmartShape/SmartStretch Meat Science Project
Provedor de dados: 31
Autores: Taylor,   Johanne; Toohey,   Edwina.
SmartShape™/SmartStretch™ is technology that uses air pressure to shape meat into an even form and to stretch hot-boned meat to prevent muscle contraction during rigor mortis, which produces more tender meat. A project that was designed to research the ability of the technology to create more tender meat and to introduce the technology to industry was conducted from April 2007 to June 2011. Varied success in research results and the needs of industry have shown that the SmartShape™ function, which shapes pieces of meat into an even and easy to manage form, is of most value to industry. The technology is being adopted by a major Australian beef processor and will be commercialised in late 2011.

Process versus product: which determines consumer demand for genetically modified apples?
Provedor de dados: 31
Autores: Kaye-Blake,   William; Bicknell,   Kathryn; Saunders,   Caroline M.
One debate in the literature regarding consumers’ reactions to genetically modified food (GMF) centres on whether consumers react to the process of gene technology or to the specific GMF products. Results from a choice experiment survey in New Zealand indicate that consumers are heterogeneous with regard to GMF and that some modifications are viewed more positively than others. These findings suggest that for some consumers the process of gene technology is the decisive factor in evaluatingGMF, while for others the different potential GMF products are valued according to their enhanced attributes.

Australian farmers operate in one of the most risky farming environments in the world. They have to cope with numerous sources of risk including weather uncertainty, variable market prices, and institutional changes in their business management. This paper reports results from two case studies undertaken to examine the issues of farming risks and risk management strategies in Australia. The first case study found that unpredictable weather, financial risk, marketing risk, and personal risk were regarded as the major sources of risk among farmers in the Upper Eyre Peninsula of South Australia. The main risk management strategies used by farmers in that region included diversifying crop varieties, adopting minimum tillage farming practices, minimising the...

The profitability of wool production after surface application of lime and superphosphate on acid soils
Provedor de dados: 31
Autores: Khairo,   Salahadin A.; Norton,   Mark R.
Soil acidity is one of the major farm management problems on the Southern Tablelands of NSW. Soil acidity occurs naturally and yet some agricultural practices exacerbate the process through nitrification, leaching, removal of produce and accumulation of organic matter in the soil. A grazing experiment was conducted between 1999 and 2008 near Sutton, NSW, to assess the impact of various combinations of lime and superphosphate application, and stocking rates, on the profitability and sustainability of wool production on the Southern Tablelands. The profitability of 15 alternative experimental treatments was assessed using the discounted cash flow analysis method for a Merino wether enterprise. The results revealed that the highest net present value was...

GM crop technology and trade restraints: economic implications for Australia and New Zealand
Provedor de dados: 31
Autores: Anderson,   Kym; Jackson,   Lee Ann.
How much might the potential economic benefit from enhanced farm productivity associated with crop biotechnology adoption by Australia and New Zealand (ANZ) be offset by a loss of market access abroad for crops that may contain genetically modified (GM) organisms? This paper uses the Global Trade Analysis Project (GTAP) model to estimate effects of other countries’ GM policies without and with ANZ farmers adopting GM varieties of various grains and oilseeds. The gross economic benefits to ANZ from adopting GM crops under a variety of scenarios could be positive even if the strict controls on imports from GM-adopting countries by the European Union are maintained, but not if North-East Asia also applied such trade restaints. From those gross economic...

Reductions in maximum Conservation Reserve Program (CRP) acres mandated by the 2008 Farm Act, along with relatively high agricultural commodity prices, could lead to reduced overall environmental benefits and higher CRP costs. ERS is analyzing alternative enrollment policies and practices that could increase environmental benefits per enrolled acre and lower program costs. The effectiveness of changes will depend on improved data and models to more accurately estimate the environmental benefits provided by competing offers to enroll land in the CRP.

The increase in the level of greenhouse gas (GHG) emissions in the atmosphere in the last centuries, and the subsequent increase in temperature, has been a widely studied area in the last few decades. Climate change has become a key item on the political agenda due to concerns regarding the sustainability of current human consumption for future generations. Consumption of food and agricultural goods constitutes an important part of household based GHG emissions, and the relatively low costs associated with environmental improvements make it an interesting area of study to understand behavioural changes. Despite general agreement on the need to curb the amount of GHG emissions worldwide, little evidence exists regarding the best instruments policymakers can...

Value-added management practices for cow-calf producers have become prevalent as feeders have recognized the value of calves raised with certified health and weaning programs. Export markets requiring age and source verification or non-hormone treated cattle and advancement of markets for naturally raised cattle have also presented profit opportunities for cow-calf producers. This study estimates the value of value-added calf production and marketing programs. Weaned steer calves sold with certified health programs realized $7 to $10 per cwt premiums. Age- and sourceverified steers received $1 to $2 per cwt premiums exceeding added costs of about $0.67 per cwt in 2010 despite rapidly expanding supply.

The analysis simulates a potential confounder to assess the robustness of the estimated treatment effects with respect to deviations from the conditional independence assumption. The program uses the commands for propensity-score matching (att* ) developed by Becker and Ichino (Stata Journal 2: 358–377). I give an example by using the National Supported Work demonstration, widely known in the program evaluation literature.

Strategic networking is of crucial importance for innovation in small and medium sized enterprises (SMEs) as it enables these companies access external resources and overcome internal constraints. However, SMEs often lack the skills and competencies to engage in and benefit from networks. Consequently SMEs often fail in establishing strategic and efficient networks. To date, there is limited guidance available on the optimal design of such networks. Furthermore, limited guidance is available on the number of networks, and level of engagement therein, that companies should be involved with.

The labour shortages which face the Australian agricultural sector could be described as having both acute and chronic aspects. Acute labour shortages can be related to short-term factors; examples include the impacts of extended drought and strong growth within the mining sector which has led to strong competition for labour and a decline in the available labour force. The potential emergence of chronic or long-lasting labour shortages related to a decline in new entrants seeking employment in the sector is a significant issue. While acute labour shortages have been a significant focus for the agricultural industries for many years, agricultural industries now need to invest in strategies to address chronic workforce shortages and emerging skills gaps....

Social capital and soil conservation: evidence from the Philippines
Provedor de dados: 31
Autores: Cramb,   Rob A.
The formation of social capital is hypothesised to enhance collective efforts for soil conservation. The Landcare Program in the southern Philippines promotes simple conservation practices in upland environments by supporting community landcare groups and municipal landcare associations, thus augmenting social capital. A study was conducted in 2002–2003 to evaluate the Landcare Program, using a mix of quantitative and qualitative techniques. In the present paper, the relationship between social capital formation and adoption of soil conservation in theMunicipality of Lantapan is investigated. It is concluded that the Landcare Program as a whole created a valuable stock of bridging social capital, rapidly accelerating the adoption of contour farming...

An Economic Analysis of MGNREG Programme in Mysore District of Karnataka
Provedor de dados: 31
Autores: Vanitha,   S.M.; Murthy,   P.S. Srikantha.
An economic analysis of MGNREG programme has been made in the Mysore district of Karnataka during the year 2009-10. The women participation among total registered workers in MGNREGS has been found significant at 47.8 per cent. Among the total number of works executed under MGNREGS in the sample villages, 96.8 per cent have been natural resource management works and 74.2 per cent community works. More number of natural resource management works are needed to be taken up on individual farmers’ fields to make MGNREGS complementary to agriculture. Among the total participants and non-participants of MGNREGS, 70 per cent in each case were agricultural labourers. In the total income earned by participants and non participants, a major proportion was from...

Trigger Foods: The Influence of “Irrelevant” Alternatives in School Lunchrooms
Provedor de dados: 31
Autores: Hanks,   Andrew S.; Just,   David R.; Wansink,   Brian.
Rational choice theory commonly assumes that the presence of unselected choices cannot impact which among the remaining choices is selected—-often referred to as “independence of irrelevant alternatives.” We show that such seemingly irrelevant alternatives influence choice in a school lunch setting. In these lunchrooms, we provide evidence that the presence of specific side dishes-—trigger foods-—can strongly increase the sales of unhealthy à la carte options, even when the trigger foods are not selected. This behavioral anomaly can be exploited to lead children to healthier choices. We also offer a method that can be used to identify such foods.

Consumers responded to the Food and Drug Administration’s September 2006 warnings to avoid eating spinach because of possible contamination with E. coli O157:H7. While spinach expenditures fell, consumers turned to other leafy greens as substitutes. The longer term drop in retail expenditures on fresh spinach products was almost matched by gains in expenditures on other leafy greens.

One little Lebanese cucumber is not going to break the bank: Price in the choice of fresh fruits and vegetables
Provedor de dados: 31
Autores: Owen,   Kate M.; Griffith,   Garry R.; Wright,   Vic.
This paper reports on empirical research into individual consumer behaviour in the context of fresh fruit and vegetable purchases. The discussion draws on research results from two studies conducted around the actual shopping process. The findings suggest that consumers’ price response behaviour may not be consistent with that predicted by economic theory and that this could be significant at the aggregate level. The existence of ‘acceptable price ranges’ points to the presence of price thresholds within which consumers are relatively insensitive to price movements. Also of relevance is that the primary influence of the budget constraint may be at a broader level rather than at the level of choosing particular products.

In India, male out-migration from rural to urban areas has increased in recent years, especially in the Indo- Gangetic regions of the country. This indicates that most of the developed regions of India are utilizing labour force of backward areas. The paper has investigated on labour out-migration from the states of Uttar Pradesh and Bihar to find its determinants and its impacts on farm economy. The analysis of determinants shown that the number of members in a family and their educational status have a positive impact on migration. As a result of male out-migration, the women left behind in the villages assume a major role in various farm activities resulting in the so-called ‘feminization of agriculture’. It has also empowered the female members of the...

Speaking Stata: Counting groups, especially panels
Provedor de dados: 31
Autores: Cox,   Nicholas J.
Counting panels, and more generally groups, is sometimes possible in Stata through a reduction command (e.g., collapse, contract, statsby) that produces a smaller dataset or through a tabulation command. Yet there are also many problems, especially with irregular sets of observations for varying times, that do not yield easily to this approach. This column focuses on techniques for answering such questions while maintaining the same data structure. Especially useful are the Stata commands by: and egen and indicator variables constructed for the purpose. With by: we often exploit the fact that subscripts are defined within group, not within dataset. egen functions are often used to produce group-level statistics. Tagging each group just once ensures that...

A computable general equilibrium model is used to analyze the effectiveness of policy alternatives at achieving biofuel-related goals in Washington State. Policy regimes compared include blend mandates, generally funded volumetric and CO2e (CO2 equivalent) emissions-based tax/subsidy regimes, and revenue-neutral funded tax/subsidy regimes that use fossil fuel taxes to fund renewable fuel subsidies. Results suggest that a revenue-neutral CO2e emissions-based tax/subsidy is arguably the most effective single alternative for pursuing the full set of objectives emphasized in recent Washington State legislation.

Global Food Prices: Implications for Food Security in Malaysia
Provedor de dados: 31
Autores: Mohamed Arshad,   Fatimah; Hameed,   Amna Awad Abdel.
This paper examines the factors that led to the recent price hikes in food commodities and the implications to food security in Malaysia. Unlike the previous price crises, the price upsurge in 2008 resulted from the convergence of fundamental and technical factors and the increase of energy prices. The high price of crude oil has increased the demand for biofuel such as biodiesel, which utilises palm oil as the main feedstock. If this development continues, it may affect Malaysia’s capacity to produce more food as arable land will be dedicated to oil palm plantations. Hence, the landscape for food security concern has changed as energy and food demand are competing for the same pool of resources, in particular land and water. Further, low investments in...

Coherent Quantitative Analysis of Risks in Agribusiness: Case of Ukraine
Provedor de dados: 31
Autores: Tarasov,   Arthur.
Modern methods of quantitative risk analysis, specifically value-at-risk and expected shortfall approach, provide comprehensive and coherent risk evaluation throughout entire distribution of outcomes and can take agricultural business from the realm of uncertainty to specific, quantified risks. Monte Carlo simulation with autocorrelation of standard deviation shows the best results in risk modeling and is used for this research. The analysis showed that production risk is systemic within climatic regions of Ukraine with coefficients of correlation ranging from 0.25 to 0.85. Yield correlation among crops in several oblasts is low to negative, creating opportunities for diversification. However, positive price-yield correlation is dominant for agricultural...

QIC program and model selection in GEE analyses
Provedor de dados: 31
Autores: Cui,   James.
The generalized estimating equation (GEE) approach is a widely used statistical method in the analysis of longitudinal data in clinical and epidemiological studies. It is an extension of the generalized linear model (GLM) method to correlated data such that valid standard errors of the parameter estimates can be drawn. Unlike the GLM method, which is based on the maximum likelihood theory for independent observations, the GEE method is based on the quasilikelihood theory and no assumption is made about the distribution of response observations. Therefore, Akaike’s information criterion, a widely used method for model selection in GLM, is not applicable to GEE directly. However, Pan (Biometrics 2001; 57: 120–125) proposed a model-selection method for GEE...

Hence, spillovers of agricultural R&amp;D results across geopolitical boundaries have implications for measures of research impacts on productivity, and the implied rates of return to research, as well as for state, national and international agricultural research policy. In studies of aggregate state or national agricultural productivity, interstate or international R&amp;D spillovers might account for half or more of the total measured productivitygrowth. Similarly, results from studies of particular crop technologies indicate that international technology spillovers, and...

Economic substitution for US wheat food use by class
Provedor de dados: 31
Autores: Marsh,   Thomas L.
Wheat for food use is conceptualised as an input into flour production and demand is derived from an industry profit function to quantify price responsiveness and economic substitutability across wheat classes. Price and substitution elasticities are estimated for hard red winter, hard red spring, soft red wheat, soft white winter and durum wheat. In general, hard red winter and spring wheat varieties are much more responsive to their own price than are soft wheat varieties and durum wheat. Substitution elasticities indicate that hard red winter and hard red spring wheat are economic substitutes for milling purposes.

A tanulmány a magyarországi vágásra szánt, élőszarvasmarha-külkereskedelem versenyképességét, komparatív előnyeit és hátrányait vizsgálja az 1999–2010 közötti időszakban. A marhahús jelentős része elsősorban exportra kerül. Vizsgálva ennek versenyképességét megállapítható, hogy jelenleg komparatív hátránya van az EU27-en belüli marhahúspiacon. A mutatók tendenciáját tekintve a hátrány mértéke évről évre csökkenő. Az RSCA-átlag mutatója a folyamatos emelkedést követően 2008-ban pozitív volt. A külkereskedelmi mérleg minden vizsgált évben aktív. A 2008-ban kibontakozott pénzügyi válság hatása ugyanakkor érződött, s jelentős visszaesést okozott, ami mindhárom mutató értékeiben megnyilvánult.

Autores: Murthy,   P.S. Srikantha; Indumati,   S.
Using macro level data on MGNREGA performance in drought-prone states of Karnataka and Rajasthan as well as in irrigation-dominated state of Andhra Pradesh, this study has revealed that the impact of MGNREGA wage on the economic scarcity of labour is relatively modest when compared with the impact of hike in non-farm wages. Even though the provision of food security through public distribution system has contributed to the economic scarcity of labour, the relative hike in non-farm wages is contributing to higher economic scarcity of labour rather than PDS and MGNREGA wages.

Determinants of purchasing behaviour for organic and integrated fruits and vegetables in Slovenia
Provedor de dados: 31
Autores: Kuhar,   Ales; Juvancic,   Luka.
A country-vide survey related to purchasing behaviour of organic and integrated fruit and vegetables has been prepared for Slovenia. An ordered probit model of consumer choice was developed on the basis of survey results to quantify various determinants of purchase frequency for organically and integrally produced fruit and vegetables. Results show that purchase of analysed produce is most significantly influenced by their availability in retail outlets, followed by consumers’ income, health and environmental considerations, and visual attractiveness of products. Demand for organically and integrally produced fruit and vegetables could be further stimulated by targeted knowledge and awareness raising actions.

Do Caring Services Affect Off-Farm Work? Evidence from Italy
Provedor de dados: 31
Autores: Salvioni,   Cristina; Sciulli,   Dario; Parodi,   Giuliana.
The article investigates the determinants of the off-farm work decision in Italian farm households, highlighting the role of caring services. Assuming that the household simultaneously decides over the optimal allocation of time of each of its members, a multivariate probit model is used to estimate the off-farm participation equations and to control for possible correlation among them. Evidence of correlation between spouse and descendant equations are found. Results suggest that policy actions geared at encouraging the off-farm participation of farm household members ought to enhance the availability and accessibility of caring services and increase the level of education of household members.

The restoration and protection of the swampy meadow within an agricultural landscape
Provedor de dados: 31
Autores: Mactaggart,   Barbara; Bauer,   Johannes; Goldney,   David; Rawson,   Andrew.
This paper addresses some implications our limited understanding of the swampy meadow landform has on agricultural production and sustainable water management. The ecological and hydrological consequences of current water management practices have lead to a revaluation of natural approaches as an alternative to instream engineering solutions. One such approach would be the restoration/rehabilitation of the swampy meadow. These landforms act as buffering agents for floods and droughts, allow for the re-hydration of the floodplains, and have further positive effects on enhancing biodiversity and improving agricultural productivity outcomes. In this paper we examine the many confusing terms used to label the swampy meadow and postulate that this confusion,...

The potential for hazelnut production in Australia
Provedor de dados: 31
Autores: Baldwin,   Basil J.
Very few hazelnuts are produced in Australia, yet we import more than 1800 tonnes of kernels valued at more than $10 million per annum. Hazelnuts are a deciduous tree crop, that requires mild temperatures, well-drained soils and good soil moisture. Although Australia generally has a semi arid climate, climate comparisons for some areas in South-eastern Australia, compared with key production areas in the northern hemisphere, indicate there are areas in Australia with a suitable climate. Field evaluation of a range of cultivars and grower selections indicates some genotypes with potential for Australian conditions. Yields recorded for young trees grown at Myrtleford in northeastern Victoria compare very favourably with commercial yields in some of the...

Evaluating Vector-Virus-Yield Interactions for Peas and Lentils under Climatic Variability: A Limited Dependent Variable Analysis
Provedor de dados: 31
Autores: Elbakidze,   Levan; Lu,   Liang; Eigenbrode,   Sanford.
This study examines the effects of climatic conditions on interactions among pea and lentil yields, pea aphid Acyrthosiphon pisum (Harris) infestations, and outbreaks of PEMV (Pea enation mosaic) and BLRV (Bean leaf roll) viruses in the Palouse region of easternWashington. The study analytically and empirically evaluates the effects of aphid outbreaks on per acre yields, implicitly including the effects of adopted pest management activities and explicitly taking into account possible effects of climatic conditions on the severity of pea aphid outbreaks. The results show that aphid outbreaks have historically decreased pea and lentil yields by approximately 5% and 7% on average respectively.

Taxing Caloric Sweetened Beverages To Curb Obesity
Provedor de dados: 31
Autores: Smith,   Travis A.; Lin,   Biing-Hwan; Morrison,   Rosanna Mentzer.
High U.S. obesity rates have prompted calls for a tax on caloric sweetened beverages. Faced with such a tax, consumers are likely to substitute nontaxed beverages, such as bottled water, juice, and milk. A tax that increases the price of caloric sweetened beverages by 20 percent could cause an average reduction of 3.8 pounds of body weight over a year for adults and 4.5 pounds for children.

„Kísértet járja be Európát és Észak-Amerikát: az erdőpusztulás kísértete.” Ezzel a drámai hangvételű mondattal kezdődik a World Resources 1986. évi kötetének erdőkkel foglalkozó része, ami a 70-es években kezdődött nagyarányú erdőpusztulás világméretű „jajkiáltása” volt, melynek visszhangja: „Mentsétek meg a Föld erdeit – amíg nem késő, amíg van mit megmenteni és megőrizni!” Nemzetközi tudományos, világméretű társadalmi fórumok témájává vált az erdő. Az emberiség egyre jobban ráébredt arra, hogy az erdő az emberiség létfeltételeinek elengedhetetlen része. Ebben nagy jelentősége volt a Római Club állásfoglalásának a növekedés határairól. A Stockholmban rendezett első környezetvédelmi világértekezlet, majd a Brundtland Bizottság közös jövőnkről készített...

An Update on the Consequences of EU Sugar Reform
Provedor de dados: 31
Autores: Moyo,   Sibusiso; Spreen,   Thomas H.
Since its formation the European Union (EU) has employed a rather complicated policy to ensure high prices to domestic sugar growers and trade preferences to certain sugar exporting countries, e.g. the African Caribbean and Pacific (ACP) group. One result of this policy is that the EU has been both the second largest importer and second largest exporter in the world market. Under pressure from the World Trade Organization (WTO), the EU agreed to reform its policies toward sugar in 2001, with the full effect of the reforms being fully implemented in 2006. In this paper, the impact of the sugar reform on EU production, consumption, imports, and exports is examined especially with regard to how it all affects the ACP countries who receive preferential...

Recent Developments in Farm Labour Availability in India and Reasons behind its Short Supply
Provedor de dados: 31
Autores: Alha,   Akhil; Yonzon,   Bijoyata.
The agricultural sector is India has been characterized with high supply of labour than demand, low wages, skewed distribution of land, and limited options of earning livelihood. This sector has undergone a vast change in recent past, mainly due to the increased rural-to-urban migration and partly due to the inception of MGNREGS and other public works. The structural changes in Indian economy in recent past have made male-migration a lucrative phenomenon while schemes like MGNREGS are found to be attractive for females in rural locations due to various reasons discussed in the paper. This has caused a shortage of farm labour and consequently, an upward push in agricultural wages. The study has suggested that there is a need to implement MGNREGA and other...

Beszerzés az észak-alföldi zöldség-gyümölcs feldolgozó vállalkozásokb
Provedor de dados: 31
Autores: Villányi,   Reka.
Az Észak-alföldi Régióban – köszönhetően Szabolcs-Szatmár-Bereg megyének – összesen 60 vállalkozás, szövetkezet, betéti társaság, kft. és rt. foglalkozik zöldség-gyümölcs feldolgozással, konzerv- és fagyasztott termékek gyártásától a pálinka- és lekvárkészítésig. Megállapítható, hogy minél nagyobb az éves árbevétel, annál nagyobb szerepet kap a beszerzési funkció, az ezzel kapcsolatos ráfordítások és a szervezettség. Önálló beszerzési szervezet csupán 13 vállalkozásnál található a hatvan feldolgozóból. Ezek 500 millió Ft feletti árbevétellel rendelkező vállalkozások. A megfelelő beszállító megtalálása, a velük való hosszú távú kapcsolatok kialakítása egyformán fontos, ha van, ha nincs a szervezetben önálló beszerzés. Ahol nincsen beszerzési szervezet, ott...

A világ májtermelésének növekedése azt jelzi, hogy e különleges termék fogyasztása iránti igény várhatóan hosszabb távon fennmarad. A termelés szerkezetében azonban átrendeződés várható az olcsóbb hízott kacsamáj javára. Ugyanakkor a libamáj a hízottmáj-termékcsoportban csúcsminőség marad. Magyarország, mivel Franciaország után a legnagyobb májtermelő ország, továbbra is mindkét termék előállításában érdekelt lesz. Hazánk már évtizedek óta a világ vezető libamájtermelő országa, de a jövőben új piaci versenytársak (pl. Kína) megjelenésére is számíthat a világ májkereskedelmében. Emellett más országok növekvő kacsamájtermelése is egyre nehezebbé teszi a magyarországi májtermékek külpiaci értékesítését. Mivel a jelenlegi gyakorlattól eltérő módon hízott májat...
