To help integrated natural resource management (INRM) research "deliver the goods" for many of the world's poor over a large area and in a timely manner, the authors suggest a problem-solving approach that facilitates the scaling out of relevant agricultural practices. They propose seven ways to foster scaling out: (1) develop more attractive practices and technologies through participatory research (2) balance supply-driven approaches with resource user demands, (3) use feedback to redefine the research agenda, (4) encourage support groups and networks for information sharing, (5) facilitate negotiation among stakeholders, (6) inform policy change and institutional development, and (7) make sensible use of information management tools, including models...

The Choice of Tillage, Rotation, and Soil Testing Practices: Economic and Environmental Implications
Provedor de dados: 31
Autores: Wu,   JunJie; Babcock,   Bruce A.; Lakshminarayan,   P.G.
Which management practices farmers adopt has a significant effect on agricultural pollution. Research has analyzed factors influencing adoption of a single management practice. But often adoption decisions about many practices are made simultaneously, which suggests use of a polychotomous-choice model to analyze decisions. We apply such a model to the choice of alternative management practices on cropland in the Central Nebraska Basin and control for self-selection and the interaction among alternative practices. We use the results of the choice model to estimate the economic and environmental effect so adopting alternative combinations of management practices.  Our results suggest that crop rotation and soil N testing are complementary practices, perhaps...

Autores: Czap,   Natalia V.; Czap,   Hans J.; Khachaturyan,   Marianna; Lynne,   Gary D.; Burbach,   Mark E.
This paper further tests dual interest theory and the metaeconomics approach to environmental choice, recognizing a possible role for empathy-sympathy (the basis for an internalized, shared other-interest) in tempering and conditioning the more fundamental tendency to pursue self-interest. To test, we focus on rivers flowing through agricultural areas carrying sediments, chemicals, and fertilizers which are making their way into downstream rivers and lakes. We use data from a framed experiment. Farmers decide on the usage of conservation technology to lessen impacts on the water quality in downstream areas, which is more costly. The results confirm our hypotheses, demonstrating that upstream farmers who practice conservation are tempering profit...

The Conservation Reserve Program in the Presence of a Working Land Alternative: Implications for Environmental Quality, Program Participation, and Income Transfer
Provedor de dados: 31
Autores: Feng,   Hongli; Kling,   Catherine L.; Kurkalova,   Lyubov A.; Secchi,   Silvia; Gassman,   Philip W.
The United States has invested large sums of resources in multiple conservation programs for agriculture over the past century. In this paper we focus on the impacts of program interactions. Specifically, using an integrated economic and bio-physical modeling framework, we consider the impacts of the presence of working land programs on a land retirement for an important agricultural region—the Upper Mississippi River Basin (UMRB). Compared to a land retirement only program, we find that the presence of a working land program for conservation tillage results in significantly lower predicted signups for land retirement at a given rental rate. We also find that the presence of both a large working land and land retirement program can result in more...

A GROSS MARGIN COMPARISON OF RETURNS TO NEMATICIDE TREATMENT IN CONTINUOUS AND ROTATION TRITICALE-SOYBEAN PRODUCTION
Provedor de dados: 31
Autores: Stark,   C. Robert, Jr.; Dowler,   C.C.; Johnson,   A.W.; Baker,   S.H.
A study of irrigated strip-till soybean production compared gross margins over nematicide expense for a continuous triticale-soybean system versus a two-year rotation system alternating triticale-soybean with triticale-cotton. Half of the replicated plots under each system received nematicide treatment. Gross margins were calculated using recorded yields and Georgia average market prices by marketing years. Mean gross margins for untreated plots were not significantly different between crop-sequence systems. Within each system, however, mean gross margins were significantly higher for plots not receiving nematicide treatment versus treated plots, even when treated plots produced greater yields.

ALTERNATIVE COTTON PRODUCTION SYSTEMS
Provedor de dados: 31
Autores: Parvin,   David W., Jr.; Cooke,   Fred T., Jr.; Martin,   Steven W.
Mississippi cotton farmers are adjusting to the current problem of low cotton price and high cotton production cost by modifying the way(s) they have traditionally grown cotton. This paper compares seven alternative production systems to the costs and returns associated with the conventional or traditional system labeled "solid cotton, 8-row equipment."  Systems that combine wider equipment (less labor and machinery time per acre) with reduced tillage technology appear to offer opportunities to increase returns. Specific adjustments on individual farms will probably be dominated by the distribution of soil types.

Green Technologies for a More Sustainable Agriculture
Provedor de dados: 31
Autores: Hrubovcak,   James; Vasavada,   Utpal; Aldy,   Joseph E.
For U.S. agriculture to continue along a sustainable path of economic development, further production increases must be generated by technologies that are both profitable and more environmentally benign. In this context, we assess the role of these green or sustainable technologies in steering agriculture along a more sustainable path. However, the lack of markets for the environmental attributes associated with green technologies can limit their development. In addition, simply making a technology available does not mean it will be adopted. Experience with green technologies such as conservation tillage, integrated pest management, enhanced nutrient management, and precision agriculture demonstrates that even when technologies are profitable, barriers to...

The Impact of Weather Extremes on Agricultural Production Methods: Does Drought Increase Adoption of Conservation Tillage Practices?
Provedor de dados: 31
Autores: Ding,   Ya; Schoengold,   Karina; Tadesse,   Tsegaye.
The paper combines panel data techniques with spatial analysis to measure the impact of extreme weather events on the adoption of conservation tillage. Zellner’s SUR technique is extended to spatial panel data to correct for cross-sectional heterogeneity, spatial autocorrelation, and contemporaneous correlation. Panel data allow the identification of differences in adoption rates. The adoption of no-till, other conservation tillage, and reduced-till are estimated relative to conventional tillage. Extremely dry conditions in recent years increase the adoption of other conservation tillage practices, while spring floods in the year of production reduce the use of no-till practices.

Temporal and Spatial Evaluation of Soil Conservation Policies
Provedor de dados: 31
Autores: Lakshminarayan,   P.G.; Babcock,   Bruce A.
This paper presents estimates of the benefits and costs of alternative soil conservation policies in a spatially and temporally consistent framework. The policies considered are implementation of soil conservation practices with an objective of reducing erosion to a site's tolerance level and a policy with an objective of a voluntary 50% reduction in conventional tillage. Costs and erosion benefits of these two policies are compared with that obtained from CRP. The changes in erosion and cost are estimated relative to 1992 levels. The analysis is conducted on every NRI point in a 12-state region in the north central United States. Erosion metamodels estimated using site-specific resource, production, topography, and weather data make such an endeavor...

THE IMPACT OF CONSERVATION TILLAGE ON THE PRODUCTIVITY AND STABILITY OF MAIZE CROPPING SYSTEMS: A CASE STUDY IN WESTERN MEXICO
Provedor de dados: 31
Autores: Jourdain,   Damien; Scopel,   Eric; Affholder,   Francois.
This paper examines the economics of introducing conservation tillage into maize cropping systems in the state of Jalisco, in the western part of Mexico. A stochastic cost-benefit analysis (SCBA) of introducing conservation tillage in two contrasting agro-climatic zones in the four main maize management systems in the area was carried out. The SCBA takes into account the effects of conservation tillage on average returns and fully evaluates its potential risk-reducing aspect. The SCBA results were then used for a stochastic dominance analysis to evaluate farmers' incentives, characterized by their aversion to risk. The analysis reveals that although conservation tillage is economically viable, cash-constrained farmers, especially in the dry areas, may not...

Factors influencing adoption of conservation tillage in Australian cropping regions
Provedor de dados: 31
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...

A Risk Analysis of Converting CRP Acres to a Wheat-Sorghum-Fallow Rotation
Provedor de dados: 31
Autores: Williams,   Jeffery R.; Llewelyn,   Richard V.; Pendell,   Dustin L.; Schlegel,   Alan J.; Troy,   Dumler.
This study examines the economic potential of producing a wheat (Triticum aesitivum) and grain sorghum (Sorghum bicolor (L.) Moench) rotation with three different tillage strategies compared to the Conservation Reserve Program (CRP) in a semi-arid region.  This research uses stochastic efficiency with respect to a function (SERF) to determine the preferred management strategies under various risk preferences and utility-weighted certainty equivalent risk premiums.  Yields, input rates, and field operations from an experimental field in western Kansas are used to calculate net returns for each tillage strategy.  Although current net returns to crop production using reduced tillage and no-tillage strategies are higher than CRP, risk analysis indicates CRP...

Autores: Lewandrowski,   Jan; Peters,   Mark; Jones,   Carol Adaire; House,   Robert M.; Sperow,   Mark; Eve,   Marlen; Paustian,   Keith H.
Atmospheric concentrations of greenhouse gases can be reduced by withdrawing carbon from the atmosphere and sequestering it in soils and biomass. This report analyzes the performance of alternative incentive designs and payment levels if farmers were paid to adopt land uses and management practices that raise soil carbon levels. At payment levels below $10 per metric ton for permanently sequestered carbon, analysis suggests landowners would find it more cost effective to adopt changes in rotations and tillage practices. At higher payment levels, afforestation dominates sequestration activities, mostly through conversion of pastureland. Across payment levels, the economic potential to sequester carbon is much lower than the technical potential reported in...

GREEN SUBSIDIES IN AGRICULTURE: ESTIMATING THE ADOPTION COSTS OF CONSERVATION TILLAGE FROM OBSERVED BEHAVIOR
Provedor de dados: 31
Autores: Kurkalova,   Lyubov A.; Kling,   Catherine L.; Zhao,   Jinhua.
Because of payoff uncertainties combined with risk aversion and/or real options, farmers may demand a premium in order to adopt conservation tillage practices, over and above the compensation for the expected profit losses (if any). We propose a method of directly estimating the financial incentives for adopting conservation tillage and distinguishing between the expected payoff and premium of adoption based on observed behavior. We find that the premium may play a significant role in farmers' adoption decisions.

Limited Access to Conservation: Limited- Resource Farmer Participation in the Conservation Security Program in the Southeast
Provedor de dados: 31
Autores: Bergtold,   Jason S.; Molnar,   Joseph J.
The paper examines the joint adoption of conservation tillage, crop rotations, and soil testing by small and limited-resource farmers in the Southeast. The objectives are to determine the potential eligibility of small farmers for the Conservation Security Program, examine socioeconomic factors affecting adoption, and assess the interdependence between adopting different conservation practices. Results indicate that conservation management, ethnicity, and farm characteristics affect practice adoption. Of the producers surveyed in the study, 7% meet Conservation Security Program eligibility requirements, while the other 93% have less than a 20% likelihood of adopting the needed practices to qualify.

Adoption of herbicide-tolerant cotton and conservation tillage may be simultaneously related.  Bayes' theorem and a two-equation logit model were used to test the simultaneity hypothesis.  Evidence for Tennessee suggests that adoption of these technologies reduced residual herbicide use and soil erosion more than if adoption of these technologies were independent.

WILL SOUTHERN AGRICULTURE PLAY A ROLE IN A CARBON MARKET?
Provedor de dados: 31
Autores: Zeuli,   Kimberly A.; Skees,   Jerry R.
While a carbon market offers substantial opportunities for US agriculture, regional differences in such a market are often ignored. This paper focuses on the advantages and challenges for agriculture in the South. The potential of two promising options are analyzed: conversion from cropland to forests and greater use of conversation tillage. It is argued that the right institutional arrangements can overcome three fundamental challenges to an efficient carbon market: transaction costs, risk, and perverse incentives. Some examples are given, such as the use of a farmer-owned organization and the provision of land use and carbon information by the government.

Simultaneous Adoption of Herbicide-Resistance and Conservation-Tillage Cotton Technologies
Provedor de dados: 31
Autores: Roberts,   Roland K.; English,   Burton C.; Gao,   Qi; Larson,   James A.
If adoption of herbicide-resistant seed and adoption of conservation-tillage practices are determined simultaneously, adoption of herbicide-resistance seed could indirectly reduce soil erosion and adoption of conservation-tillage practices could indirectly reduce residual herbicide use and increase farm profits. Our objective was to evaluate the relationship between these two technologies for Tennessee cotton production. Evidence from Bayes' theorem and a two-equation logit model suggested a simultaneous relationship. Mean elasticities for acres in herbicide-resistance seed with respect to the probability of adopting conservation-tillage practices and acres in conservation-tillage practices with respect to the probability of adopting herbicide-resistance...

MULTIPLE BENEFITS OF CARBON-FRIENDLY AGRICULTURAL PRACTICES: EMPIRICAL ASSESSMENT OF CONSERVATION TILLAGE
Provedor de dados: 31
Autores: Kling,   Catherine L.; Kurkalova,   Lyubov A.; Zhao,   Jinhua.
In this study, we estimate empirically the multiple benefits of a subsidy policy that would offer payments to farmers in return for the adoption of conservation tillage and compare the outcomes of alternative targeting designs for such a policy. Using data for roughly 12,000 National Resource Inventory (NRI) points, we simulate for the state of Iowa the least-cost policy schemes for offering payment incentives. We use an economic model of conservation tillage adoption to evaluate the costs of adoption, and we use a model that simulates physical processes (Environmental Policy Integrated Climate, or EPIC) to estimate the environmental benefits of adoption at each of the NRI points.   We assess the costs and environmental consequences of two targeting...

CONSERVATION TILLAGE AND PESTICIDE USE IN THE CORNBELT
Provedor de dados: 31
Autores: Fuglie,   Keith O.
Adoption of conservation tillage can lead to substantial environmental benefits from reduced soil erosion.  But benefits may be partially offset if adoption increases reliance on agricultural chemicals.  Using area study data from the Cornbelt, this study examines factors affecting adoption of no-till and other conservation tillage systems and their effect on chemical use and corn yield.  The results find no evidence that herbicide or fertilizer application rates are higher on fields with conservation tillage systems compared with conventional tillage.  However, insecticide use may increase somewhat and yield may be lower.  Current demographic trends in U.S. agriculture favor continued diffusion of conservation tillage.

Tillage systems and nutrient sources affecting soil cover, temperature and moisture in a clayey oxisol under corn
Provedor de dados: 90
Autores: Veiga,Milton da; Reinert,Dalvan José; Reichert,José Miguel.
Tillage affects soil physical properties, e.g., porosity, and leads to different amounts of mulch on the soil surface. Consequently, tillage is related to the soil temperature and moisture regime. Soil cover, temperature and moisture were measured under corn (Zea mays) in the tenth year of five tillage systems (NT = no-tillage; CP = chisel plow and single secondary disking; CT = primary and double secondary disking; CTb = CT with crop residues burned; and CTr = CT with crop residues removed). The tillage systems were combined with five nutrient sources (C = control; MF = mineral fertilizer; PL = poultry litter; CS = cattle slurry; and SS = swine slurry). Soil cover after sowing was greatest in NT (88 %), medium in CP (38 %) and lowest in CT treatments...

Provedor de dados: 91
Autores: Bandeira,Douglas H.; Bertol,Ildegardis; Vázquez,Eva V.; Ramos,Júlio C.; Bertol,Camilo.
ABSTRACT Water erosion in soil is influenced by several factors, including rain, relief, cover, and management and conservation practices. Also, erosion is affected by pig slurry (PS) applied to the soil as a fertilizer. The objectives of this research were i): to evaluate water erosion in a Humic Cambisol cultivated with Zea mays L., Avena strigosa, Glycyne max L., and Raphanus sativus in rotation after PS dispersal under different tillage treatments, namely: no-tillage (NT), minimum tillage (MT), rotation tillage (RT) and conventional tillage (CT) , and ii): to compare erosion before and after PS application in a single dose of 50 m3 ha-1 in each crop, soon after the germination of the crops. NT had lower soil and water loss, which were reduced by 81 and...

Phosphate fertilization and phosphorus forms in an Oxisol under no-till
Provedor de dados: 63
Autores: Olibone,Dácio; Rosolem,Ciro Antonio.
Under no-till phosphorus (P) accumulates in a few centimeters of the topsoil layer. Plant residues left on the soil surface release P and organic acids, which may improve P availability and fertilizer efficiency, including both soluble (such as triple super phosphate) and less soluble sources (such as reactive natural phosphates). In this study, soybean response to P fertilizer and P forms in the top 40 cm of an Oxisol were evaluated after surface application of different phosphates in a 5-year-old no-till system. Treatments consisted of 0 or 80 kg ha-1 of total P2O5 applied on the soil surface, both as natural reactive phosphate (NRP) or triple super phosphate (TSP). In addition, 80 kg ha-1 of P2O5 were applied to subplots, in furrows below and beside the...

Phosphorus loss by surface runoff in no-till system under mineral and organic fertilization
Provedor de dados: 63
Autores: Bertol,Oromar João; Rizzi,Nivaldo Eduardo; Favaretto,Nerilde; Lana,Maria do Carmo.
The no-till system has been intensively used in the state of Paraná, Brazil, and it has increased the nutrients level at the soil surface. This has contributed for nutrient losses via runoff and consequently, off-site water pollution. The objective of this study was to evaluate phosphorus loss in surface runoff by simulated rainfall on an Oxisol, under no-till system following application of mineral fertilizer and liquid swine manure. Nitrogen, soil and water losses from the same study are reported in a separated paper. The application of liquid swine manure, compared with mineral fertilization, increased runoff concentration of total P, particulate P and dissolved reactive P by 193%, 111% and 506%, respectively, averaged for all rainfall intensities....

Study on the effect of tillage on the change of soil properties, nitrogen leaching away from root zone, yield and plant nutrient uptake of maize grown on Warin soil series (Arenic Haplustult) was carried out in Ban Nonsomboon, Krissana sub-district, Sikhiu Nakhon district, Nakhon Ratchasima province. The experimental design employing randomized complete block design consisted of four various tillage methods as follow; conventional tillage (using 3-disc followed by 7-disc plough), reduced tillage (using only 7-disc plough), mulch tillage (using 7-disc plough with plant residues left to cover soil surface) and no-tillage. Results showed that conventional tillage tended to give a maximum grain yield of 566 kg/rai. The lowest amount of grain yield (479 kg/rai)...

Desafios e oportunidades do sistema de plantio direto na palha para a produção agrícola familiar em argissolo arenoso no sudoeste da Amazônia brasileira.
Provedor de dados: 119
Autores: COSTA, F. de S.; LAMBERTUCCI, D. M.
A mudança no uso da terra na Amazônia brasileira ainda no sistema de derruba e queima tem mídia global. Esse sistema é utilizado também na limpeza de áreas já desmatadas para novos cultivos e renovação de pastagens, independente da escala de produção. É necessário pesquisar alternativas tecnológicas para a agricultura familiar devido a suas vulnerabilidades social, de segurança alimentar e fontes de renda. A agricultura familiar cultiva mandioca, milho e feijão, entre outros, importantes para a sua segurança alimentar e comercialização de excedentes, geralmente em solos de baixa qualidade intrínseca, baixo uso de tecnologia, com problemas no escoamento, no mercado de insumos e alternativas de venda. Para a mudança desse cenário uma pesquisa participativa é...

Nowadays, using of conservation tillage instead of conventional tillage has been changing attitudes from conventional agriculture to sustainable agriculture. The tillage method affects directly soil and water quality. Actions relative to optimized agricultural management such as conservation tillage methods has adopted at recent years by agronomists and agricultures, due to agricultural and environment advantages. These advantages consist of soil and water quality improving, wind and water erosion prevention, evaporation reduction, soil surface temperature reduction, greenhouse gases reduction, fuel consumption reduction, and etc. In conversation tillage, more than 30% agricultural production residues remain on the ground. For evaluation of residues cover...
