Kimberly sugar beet germplasm evaluated for rhizomania and storage rot resistance in Idaho, 2015.
Provedor de dados: 18
Autores: Eujayl, Imad A.; Strausbaugh, C.A.
Rhizomania caused by Beet necrotic yellow vein virus (BNYVV) and storage losses are serious sugar beet production problems.  To identify sugar beet germplasm lines with resistance to BNYVV and storage rots, 11germplasm lines from the USDA-ARS Kimberly sugar beet program were screened.  The lines were grown in a sugar beet field infested with BNYVV and one treated with Telone II (18 gpa) in Kimberly, ID during the 2015 growing season in a randomized complete block design with 4 replications.  At harvest on 7 October 2015, roots were dug and evaluated for symptoms of rhizomania and also placed in an indoor commercial sugar beet storage building.  After 126 days in storage, samples were evaluated for surface fungal growth.  Roots for entries from the RZ field...

Evaluation of Nitrogen and Phosphorus Fertilizer Placement With Strip Tillage for Irrigated Pacific Northwest Corn Production
Provedor de dados: 18
Autores: Tarkalson, D.D.; Bjorneberg, D.L.
Nutrient placement options with strip tillage (ST) can potentially improve plant nutrient utilization and increase crop yield compared to conventional fertilizer placement practices under conventional tillage (CT). The effects of tillage practice and nitrogen (N) and phosphorus (P) placement on grain yield, biomass yield (whole plant, grain + cobs + stover), and N and P uptake of field corn (Zea mays L.) were assessed on four sites during 2007 and 2009 at the USDA-ARS Northwest Irrigation &amp; Soils Research Laboratory at Kimberly, ID. During each year, two locations (eroded and not eroded from furrow irrigation) were utilized as study locations. Band placement of fertilizer with ST increased corn grain yield by 12.5 % (11 bu/acre) and 25.9% (26 bu/acre)...

Nitrogen Use Efficiency of Irrigated Corn for Three Cropping Systems in Nebraska
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...

Autores: Strausbaugh, C.A.; Eujayl, Imad A.; Rearick, E.; Foote, P.
Thirty-two transgenic (glyphosate resistant) and six conventional commercial sugar beet 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 infection for rhizomania development. The plots were planted on 3 Apr 07 to a density of 142,560 seeds/A,  and thinned to 47,520 plants/A on 23 May. Plots were four rows (22-in. row spacing) and 24 ft long. The experimental  design was a randomized complete block design with four replications per entry. 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 26 Sep. At harvest the roots were...

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...

Row Cropping Sandy Soils Under Sprinklers Using a Winter Grain Cover to Control Wind Erosion
Provedor de dados: 18
Autores: Cary, J.W.; Kohl, R.A.; Westermann, D.T.; Rickman, R.W.
One of the most effective ways to prevent the wind erosion  of sandy soils is to maintain a continuous crop cover. Summer  row cropping following a winter grain cover offers several  attractive features, although it does present management  problems. The grain cover must be established in the fall  after harvesting the row crop, and the transition back to a  row crop in the spring must be made without leaving the  soil surface unprotected from the wind.  This report summarizes 4 years of observations and  exploratory studies in which a variety of cover-row cropping  management systems were tested with emphasis on methods  for establishing row crops directly in the winter cover.  Pertinent literature and observations of other field trials  are also discussed.

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...

Metals in waste foundry sands and an evaluation of their leaching and transport to groundwater
Provedor de dados: 18
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...

Dairy Manure Nitrogen Availability in Eroded and Noneroded Soil for Sugarbeet Followed by Small Grains
Provedor de dados: 18
Autores: Lentz, R.D.; Lehrsch, G.A.; Brown, Bradford; Johnson-Maynard, J.; Leytem, A.B.
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. Plots were planted to sugarbeet (Beta vulgaris L.), winter wheat (Triticum...

Control of Sediments, Nutrients, and Adsorbed Biocides in Surface Irrigation Return Flows
Provedor de dados: 18
Autores: Carter, David L.; Bondurant, James A.
The technology available for the control of sediments, nutrients, and  adsorbed biocides in surface irrigation return flows has been reviewed  and evaluated. Some of this technology could be applied immediately to  reduce sediment and associated nutrient and biocide concentrations in  surface irrigation return flows. Much of the available information  needs to be integrated to develop improved control practices. New ideas  and new control technology are needed. Economic incentive programs are  needed to improve acceptance of control technology. The factors controlling  erosion and subsequent sediment concentrations in surface  irrigation return flows, and how these factors can be managed to reduce  erosion and sediment concentrations are reviewed and...

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....

Distribution Control and Measurement of Irrigation Water on the Farm
Provedor de dados: 18
Autores: Robinson, A.R.; Lauritzen, C.W.; Muckel, D.C.; Phelan, Jack.
An irrigation system should be designed  to provide correct distribution,  control, and measurement of the irrigation  water.      Usually a farmer takes his irrigation  water from a canal through a headgate.  Or he may receive it from a pipeline  regulated by a valve, or perhaps from  his own well and pump. Open ditches  are most commonly used to carry the  water to the fields. Water control structures  are used to get it out of the ditches  and onto the fields. Measurement devices  are needed so the farmer can tell  how much water he has applied to his  field at any irrigation or over the  season.      Several types of structures are used  to divert, convey, control, or measure  irrigation water. Some of these are  described, and their functions...

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...

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...

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...

Phosphorus losses in runoff after application of litter from broilers fed high-available phosphorus corn feed
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...

Plant analyses and interpretation
Provedor de dados: 18
Autores: Westermann, D.T.
Plant analysis historic beginnings are generally attributed to T. de Saussure (1804)  following studies by van Helmont, Joseph Priestly, Henry Cavenish, and Antonine  Lavoisier. de Saussure showed that the composition of plant ash varied with the  part analyzed, with the age of the plant, and with the soil upon which the plant  grew. The ash was chiefly composed of alkalis and phosphates. Erasmus Darwin  in his 1800 book, Phytogia: The Philosophy of Agriculture and Gardening (London,  J. Johnson) wrote that both nitrogen (N) and phosphorus (P) were essential  components of plants. In 1833, the Fifth Duke of Richmond showed that the value  of bone meal fertilizing was due to its P component rather than calcium (Ca), although  Justus von Liebig (1852) is...

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...

Managing nitrogen during the crop rotation to increase income and protect the environment
Provedor de dados: 18
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...

Autores: Strausbaugh, C.A.; Eujayl, Imad A.; Foote, P.
The Rhizoctonia-bacterial root rot complex continues to be a concerning problem in sugar beet production areas. To investigate resistance to this complex in 26 commercial sugar beet cultivars, field studies and greenhouse studies with mature roots from the field were conducted with Rhizoctonia solani AG-2-2 IIIB strains and Leuconostoc mesenteroides. Based on means for the 26 cultivars in the 2010 and 2011 field studies, fungal rot ranged from 0 to 8%, bacterial rot ranged from 0 to 37%, total rot ranged from 0 to 44%, and surface rot ranged from 0 to 52%. All four rot variables resulted in significant (P &lt; 0.0001) cultivar differences.

Sprinkler Irrigation
Provedor de dados: 18
Autores: Pair, C.H.
Sprinkler irrigation systems distribute water by  spraying it over the fields. The water is piped under  pressure to the fields. The pressure forces the  water through sprinklers or through perforations  or nozzles in pipelines and thus forms a spray.  Sprinkling is man's imitation of natural rainfall.  Nearly all irrigable soils can be sprinkler irrigated.  It is difficult, however, to sprinkler-irrigate  if the water intake rate of your soil is less than  0.10 inch per hour.

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...

Linking manure properties to phosphorus solubility in calcareous soils: Importance of the manure carbon to phosphorus ratio
Provedor de dados: 18
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...

Soil phosphorus availability differences between sprinkler and furrow irrigation
Provedor de dados: 18
Autores: Ippolito, J.A.; Bjorneberg, D.L.
Water flowing in irrigation furrows detaches and transports soil particles and subsequently nutrients such as phosphorus.  To reduce the risk of erosion and offsite phosphorus transport, producers in south-central Idaho have been converting from furrow to sprinkler irrigation.  We completed research on soil phosphorus dynamics in furrow versus sprinkler irrigated soils from four paired-fields in the region.  Surface soils (0-2.5 inches) were obtained from fields in September following barley harvest.  Furrow irrigated soils contained 38 parts per million of plant-available phosphorus (i.e. Olsen-extractable), on average, as compared to 20 parts per million under sprinkler irrigation.  These results are important as 20 parts per million extractable...

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.

Dairy manure applications and soil health implications
Provedor de dados: 18
Autores: Moore, A.; Satterwhite , Megan; Lehrsch, G.A.; McGeehan, S.
Dairy manure applications can potentially improve soil health by adding organic matter (OM) to the soil.  However, intensive dairy manure applications can cause salt accumulations on arid, irrigated soils, impairing soil health, which can reduce crop growth and yield.  Soil organic matter, a major contributor to soil health, increased by 0.02% for every ton of manure-derived organic matter applied.  While soil OM increases typically improve soil health, salt accumulations from manure applications had antagonistic effects on soil health.  As manure application rates and frequencies increased, soil properties became increasingly saline-sodic, as indicated by elevated EC and SAR values.  Aggregate stability also decreased at the heaviest annual manure...

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.

The Pathfinder Uranium Mine which is located in southeastern Wyoming,  was actively mined during the 1960's-1980's. Reclamation involved returning the  spoil/overburden and replacing the salvaged topsoil. The area was revegetated in  1974-1977, but was not grazed until 1980-85. A grazing experiment was then  conducted to determine solubility of mineral elements in soil, uptake by plants and  absorption by grazing animals. Blood sera were collected at 28-30 day intervals  during the three grazing/growing seasons in 1980-1982. Blood sera samples were  frozen and later analyzed by ICP. When compared to published data, plants on the  reclaimed site contained lower concentrations of Ca, Mg, Mn, P, and Zn; but higher  concentrations of Cd, Cr and Ni than plants...

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...

Autores: Blecker, S.W.; STILLINGS, L.L.; MCAMACHER, M.C.; Ippolito, J.A.; DECRAPPEO, N.M.
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....

Influence of Sugarbeet Tillage Systems on the Rhizoctonia-Bacterial Root Rot Complex
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Eujayl, Imad A.
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),...

Revegetation of Fluvial Mine Tailing Deposits: The Use of Five Riparian Shrub Species
Provedor de dados: 18
Autores: Davis, N.; Meiman, P.; Brummer, J.; Ippolito, J.A.
Fluvial deposition of mine tailings has caused extensive damage to riparian ecosystems throughout the West. Willows are often used for revegetation of fluvial mine tailing deposits but some species accumulate toxic concentrations of metals in leaves and stems. A greenhouse experiment was conducted to determine the value of thinleaf alder [Alnus incana (L.) Moench spp. tinuifolia (Nutt.) Breitung], water birch (Betula occidentalis Hook.), red osier dogwood (Cornus sericea L. spp. sericea), and shrubby cinquefoil [Dasiphora fruticosa (L.) Rybd.] compared to Geyer willow (Salix geyeriana Andersson) for revegetation of fluvial tailing deposits along the Upper Arkansas River. Bare root shrubs were grown in tailings amended with lime and composted biosolids....

Hardwood biochar influences calcareous soil physicochemical and microbiological status
Provedor de dados: 18
Autores: Ippolito, J.A.; Stromberger, M.E.; Lentz, R.D.; Dungan, R.S.
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...

Influence of harvest timing, fungicides, and Beet Necrotic Yellow Vein Virus on sugar beet storage
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 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...

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,...

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...

Biochar is the carbonaceous solid byproduct of the thermochemical conversion of a carbon-bearing organic material, commonly high in cellulose, hemicelluloses, or lignin content, for the purposes of carbon sequestration and storage.  More specifically, the thermal conversion process known as pyrolysis occurs when carbon-containing substances are introduced to elevated temperatures in the absence of oxygen at varying residence times, yielding biochar.  Several pyrolysis techniques employed to produce biochar differ in the temperature of reaction and residence time in the reactor.  Different reactor residence times are described as slow (hours to days), fast (seconds to minutes), and flash (seconds).  Fast or flash pyrolysis typically occurs around 500oC with...

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: Strausbaugh, C.A.; Gallian, J.J.; Camp, S.; Foote, P.; Gillen, A.M.
Curly top of sugarbeets caused by Beet curly top virus (BCTV) was widespread from  southeastern Oregon to southcentral Idaho in 2004. Curly top first became a serious  threat to sugarbeet production in southern Idaho in 1919. By the time the first resistant  variety was released in 1935, BCTV had almost eliminated the sugarbeet industry (2).  Today this disease is largely managed through the use of resistant varieties. Early  planting and the use of systemic insecticides (phorate, aldicarb, and imidicloprid) will  also help limit curly top (1,2,4).

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
Provedor de dados: 18

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.

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.  Planting systems evaluated were (1) conventional ridgedrow with dammer-diking; (2) 3.7 m wide bed with five potato rows spaced 66 cm between adjacent rows...

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...

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...

Autores: Burns, J.C.; Fisher, D.S.; Mayland, H.F.
Forages accumulate nonstructural carbohydrates  during the day, with animals showing  preference and improved daily responses from  afternoon compared with morning cut hays. This  study evaluated alfalfa (Medicago sativa L.) hay  harvested at 0700, 1000, 1300, 1600, and 1900  h to determine how nutritive value changes during  the day and to assess the impact of these  changes on animal preference using cattle (Bos  taurus L.), sheep (Ovis aries L.), and goat (Capra  hircus L.) responses. Total nonstructural carbohydrates  were altered by time of cut (cubic contrast,  P &lt; 0.01) ranging from 85 g kg?1 at 0700 h  to 83 g kg?1 at 1000 h, then increasing to 97 g  kg?1 by 1600 h with little change at 1900 h (96 g  kg?1).

Delinearing site-specific management zones for pH-induced iron chlorosis
Provedor de dados: 18
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.

Waste molding and core sands from the foundry industry have been successfully used around the world as byproducts in geotechnical and agricultural applications.  Although waste foundry sands (WFSs) are generally not considered hazardous in nature, relevant data are not available in Argentina.  This study aimed to quantify metals in waste molding and core sands from foundries using a variety of metal-binder combinations.  Metal concentrations in WFSs were compared to those in virgin silica sands (VSSs), surface soil and soil guidance levels according to hazardous waste law 24.051 from the Argentinean Secretariat of Environment and Sustainable Development.

Detection of purple sulfur bacteria in purple and non-purple dairy wastewaters
Provedor de dados: 18
Autores: Dungan, R.S.; Leytem, A.B.
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. Analysis of the 16S rRNA genes from denaturing gradient gel electrophoresis (DGGE) bands indicated that all of the dairy wastewater ponds contained sequences...

Autores: van Donk, Simon J.; Lindgren, Dale T.; Schaaf, Daniel M.; Petersen, J.L.; Tarkalson, D.D.
Wood chip mulches are used in landscapes to reduce soil water evaporation and competition from weeds. A study was conducted over a three-year period to determine soil water content at various depths under four wood chip mulch treatments and to evaluate the effects of wood chip thickness on growth of 'Husker Red' Penstemon digitalis Nutt. plants. The effects of four wood chip thicknesses (depth of application: 0, 2.5, 5, and 10 cm) on soil water content, weed numbers, soil temperature, and height, width, stalk number, and first flower date of 'Husker Red' Penstemon were investigated. The addition of mulch, at all mulch thicknesses, conserved soil water compared to when no mulch was used. The differences in soil water content likely influenced some of the...

Autores: Eujayl, Imad A.; Strausbaugh, C.A.; Chunsheng, Lu.
KDH13 is a sugar beet (Beta vulgaris L. ssp vulgaris) doubled haploid line (PI 663862) released as a genetic stock by USDA-ARS in cooperation with the Beet Sugar Development Foundation, Denver, CO. KDH13 is resistant to beet curly top (BCT) caused by Beet curly top virus which is transmitted by the beet leafhopper (Circulifer tenellus Baker). KDH13 was extracted from the BCT resistant C762-17 (PI 560130) parental line that segregates for BCT resistance and genetic male sterility. Intensive phenotypic screening was used for selecting plants from C762-17 that showed no symptoms under fully controlled infection conditions in the greenhouse. Seed from a single plant was used as a donor of floral buds for isolation of unfertilized ovaries to regenerate KDH13...

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.

Soil phosphorus dynamics under sprinkler and furrow irrigation
Provedor de dados: 18
Autores: Ippolito, J.A.; Bjorneberg, D.L.
Furrow irrigation detaches and transports soil particles and subsequently nutrients such as phosphorus.  To reduce the risk of erosion and offsite phosphorus movement, producers can convert from furrow to sprinkler irrigation.  We completed research on soil phosphorus dynamics in furrow versus sprinkler irrigated soils from four paired fields in south central Idaho.  Surface soils (0-2.5 inches) were obtained from fields in the fall following harvest.  Furrow irrigated soils contained 38 parts per million of plant-available phosphorus (i.e. Olsen-extractable) on average, as compared to 20 parts per million under sprinkler irrigation.  These results are important as 20 parts per million Olsen-extractable phosphorus may be considered the concentration where...

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.  Scanning electron microscopy and energy dispersive x-ray analysis...

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...

Autores: Ferguson, R.B.; Kyaw, T.; Adamchuk, V.I.; Tarkalson, D.D.; McCallister, D.L.
A study was conducted over nine site/years in Nebraska, USA between 2004 and 2005 to evaluate  the potential to predict chlorosis-prone areas within fields which are relatively stable in space  and time. The study also investigated the potential benefits of site-specific cultivar management  according to chlorosis pressure. Sites were mapped for soil apparent electrical conductivity (ECa)  at two depths (0-30 cm and 0-90 cm), and soil pH at a depth of 10 cm. Sites were also sampled by  hand on a regular grid to a depth of 20 cm and analyzed for a range of soil properties. Sites were  evaluated in-season with natural color and near-infrared imagery, and at the end of the season by  yield mapping. In all or a portion of each field, replicated paired strips...

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,...

Optimal performance from center pivot sprinkler systems
Provedor de dados: 18
Autores: King, Bradley A.; Kincaid, Dennis C.
A good supply of groundwater and the commercial development  of center pivot irrigation systems significantly increased  sprinkler-irrigated acreage in southern Idaho during the late 1960s  and early 1970s. Today, center pivot systems, with their automation,  large areal coverage, reliability, high application uniformity, and ability  to operate on relatively rough topography, are replacing  surface; handline, and wheelline systems.  The irrigated area under a center pivot system expands  substantially with increasing system length. To accommodate the  increased area, the application rate increases linearly along the  center pivot lateral through one of two methods: increased flow  rates through equally spaced Sprinklers or gradually decreased  spacing of...

Seed Treatments for the Control of Insects and Diseases in Sugarbeet
Provedor de dados: 18
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...

Regression modeling weather and biolsolids effects on dryland wheat yields in Eastern Colorado, 2001-2012
Provedor de dados: 18
Autores: Barbarack, K.A.; Ippolito, J.A.; McDaniel, J.P.; Hansen., N.C.; Peterson, G.A.
In the western Great Plains, climate dictates dryland wheat (Triticum aestivum, L) productivity. Producers use inorganic N fertilizers to improve crop yields in this region, while municipalities recycle sewage biosolids in the area. Will biosolids (from the Littleton/Englewood, CO Wastewater Treatment Plant) applications to western Great Plains dryland agroecosystems interact with weather to affect wheat production? To this end, we regressed crop yields on weather variables from 2000 through 2011 at a site about 40 km (approximately 25 miles) east of Byers, CO (Byers). We used SAS (Proc Reg) to develop several multiple regression models to predict crop yields. Our model of choice included four weather parameters for Byers wheat production. Regression...

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)...

The Effect of Aldicarb on Sugarbeet Insects and Yield
Provedor de dados: 18
Autores: Blickenstaff, C.C.
Approximately 450 species of insects were collected in sugarbeet  fields in south-central Idaho over the 4-year period 1974 to 1977.  Fifty-four species or species groups were taken from 50 percent or  more of the fields sampled; 18 were classed as destructive or potentially  destructive, 14 as beneficial, and 22 of unknown function. Of  the 54, 18 were collected more commonly by sweep net, 34 were collected  more commonly by pitfall traps, and 2 were collected equally by the  two methods. Fourteen of the 54 were taken exclusively by pitfall  traps. The apparent effect of aldicarb on insect populations varied  widely with an overall reduction of about 20 percent.

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...

Autores: Lentz, R.D.; Ippolito, J.A.; Spokas, K.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,...

Commercial sugar beet cultivars evaluated for rhizomania resistance and storability in Idaho, 2010.
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Eujayl, Imad A.; Rearick, E.
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, 28 commercial cultivars were screened by growing them in a sugar beet field infested with BNYVV in Kimberly, ID during the 2010 growing season in a randomized complete block design with 4 replications.  At harvest on 18 October 2010, 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...

This publication is designed to help identify salt- and  sodium-affected soils, the salt or sodium sources, how  to take soil and water samples, how to reduce the harmful  effects of salts and sodium and where to get advice  in making reclamation and management decisions for  each situation.  Salt- and sodium-affected soils, and waters used for  irrigation, present a complex combination of problems  and possible solutions. It is not the intent here to cover  all technical aspects or possible treatment approaches  available, but rather to give a simplified overview of  what should be considered in diagnosing and managing  salt- and sodium-affected soils and irrigation waters.  Since summarizing the effects of salt and sodium on  soils and plants is...

Inhibiting water infiltration with cross-linked polyacrylamide: Seepage reduction for irrigated agriculture
Provedor de dados: 18
Autores: Lentz, R.D.
High water infiltration rates in unlined canals, reservoirs, and the inflow end of furrows relative  to outflow ends result in excessive seepage losses and reduced furrow irrigation application uniformity.  This study evaluated the use of cross-linked, anionic, polyacrylamide hydrogel (XPAM), a  water-absorbing, swellable polymer solid, for reducing infiltration and seepage losses though soil.  Experiments 1 and 2 measured the influence of soil treatments on seepage rate in soil columns  under constant-head conditions: Exp. 1 treated five soils with 0, 2.5, 5, and 10 g kg -1 XPAM; Exp.  2 applied combined XPAM (0-5 g kg-1) and NaC1 (0-5.1 g kg-1) treatments to a silt loam soil,  and separately tested the effect ofXPAM granule size and treated soil layer...

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...

Effect of irrigation amounts applied with subsurface drip irrigation on corn evapotranspiration, yield, water use efficiency, and dry matter production in a semiarid climate
Provedor de dados: 18
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...

Autores: Bjorneberg, D.L.; Ippolito, J.A.; Koehn, A.C.
Water, sediment and nutrients flowing into and out of the 82,000 ha Twin Falls,ID irrigation tract were measured from 2005 to 2008. Approximately 80% of the water flowing into the watershed was irrigation water diverted from the Snake River. About 40% of the watershed inflow returned to the Snake River. Much of this return flow was water from subsurface drain tiles and tunnels that drain shallow groundwater. Converting from furrow to sprinkler irrigation, improved irrigation management, and constructed sediment ponds have reduced sediment loss from 460 kg/ha in 1971 to &lt;100 kg/ha in 2005. In 2007 and 2008, more sediment and phosphorus entered the watershed than returned to the Snake River. Diverting irrigation water into the watershed removed 6300 Mg of...

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.

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...

The effects of phytase supplementation on performance and phosphorus excretion from broiler chickens fed low phosphorus-containing diets based on normal or low-phytic acid barley
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...

Evaluation of experimental sugar beet hybrids for resistance to curly top in Malheur County, OR, 2005
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Gillen, A.M.
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)...

Use of a surrogate to evaluate the impact of tillage on the transport of steroid hormones from manure-amended agricultural field
Provedor de dados: 18

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...

Management practices and sugar end potatoes
Provedor de dados: 18
Autores: Westermann, Dale T.
French fries processed from sugar end potatoes become  undesirably dark on one end while remaining  light on the other (fig. 1). The darkening is usually  caused by a higher concentration of reducing sugars  in the darkened end of the fry strip. Sugar ends are  associated with tubers that are pointed on the stem  end but also occur in ideally shaped tubers.  "Translucent end," "jelly end," and "sugar end"  describe the same physiological tuber problem. Translucent  end tubers with high levels of sugars develop  jelly end rot after progressive tissue breakdown  occurs. The Russet Burbank variety is particularly  susceptible to sugar end formation when subjected to  water and heat stress.

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.

Sulfate Foot Baths on Dairies and Crop Toxicities
Provedor de dados: 18
Autores: Moore, A.; Ippolito, J.A.
A rising concern with the application of dairy wastes to agricultural fields is the accumulation of   copper (Cu) in the soil. Copper sulfate (CuSO4) from cattle footbaths is washed out of dairy   barns and into wastewater lagoons. The addition of CuSO4 baths can increase Cu concentration   significantly in manure slurry, from approximately 5.0 grams per 1,000 liters to 90.0 grams per   1,000 liters. The Cu-enriched dairy waste is then applied to agricultural crops, thus raising   concerns about how soils and plants are impacted by these Cu additions.

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...

Treatment and Disposal of Sugarbeet Processing Waste Water by Irrigation
Provedor de dados: 18
Autores: Smith, J.H.; Hayden, C.W.
Irrigation with sugarbeet processing waste  water was studied at three locations for 2 or 3  years where perennial grass and alfalfa were  irrigated by flooding specially graded fields.  Experimental sites were scheduled for  irrigation at intervals of 1, 2, or 4 weeks. This  schedule was maintained for the first year until  the weekly irrigated plots were discontinued  because of excessive loading. Waste water was  sampled twice weekly from the sugar factories,  and water samples were extracted from the soil  at depths of from 15 to 150 cm each time the  fields were irrigated. All water samples were  analyzed for chemical oxygen demand, total  nitrogen, phosphorus, potassium, electrical  conductivity, calcium, magnesium, sodium,  sodium absorption ratio,...

Identification and mapping of markers linked to the Mi Gene for root-knot nematode resistance in peach
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,...

Phosphorus Biogeochemistry Across a Precipitation Gradient in Grasslands of Central North America
Provedor de dados: 18
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...

Switchgrass Biochar Effects Two Aridisols
Provedor de dados: 18
Autores: Ippolito, J.A.; Novak M, J; Busscher, W.J.; Ahmedna, M.; Rehrah, D.; Watts, D.W.
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,...

Sugarbeet
Provedor de dados: 18
Autores: Panella, Leonard W.; Kaffka, S.K; Lewellen, R.T.; McGrath, J.M; Metzer, M.S.; Strausbaugh, C.A.
Sugar beet is an industrial crop, in that it is neither the seed nor the foliage that is the plant constituent of interest – not even the root itself, but rather sucrose refined from the root.  For this reason yield is a complex trait, when looking at the amount of refined white sugar produced per area.  Yield is calculated by the root weight times the percentage of that weight that is sucrose (usually expressed as percent of fresh weight), but also by the amount of the sucrose that can be extracted from the beet juice during processing (often expressed as juice purity or percent loss to molasses).  All three of these components are variable in a population and can be improved through plant breeding.  Percent sucrose is positively correlated to the amount...

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...

Current knowledge on the environmental fate, potential impact, and management of growth-promoting steroids used in the US beef cattle industry
Provedor de dados: 18

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...

Antibiotics in agroecosystems: Introduction to the special section
Provedor de dados: 18

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...

Use of Amendments to Reduce Water Requirements for Stand Establishment of Small-Seeded Crops
Provedor de dados: 18
Autores: Dennis, R.E.; Edmond, C.W.; Robbins, C.W.
Soil crusting after planting is a serious problem in stand establishment  of small-seeded crops in the Southwest. When crusting occurs in a  saline, warm soil, stand establishment problems are especially severe. It  is customary to use costly irrigation water to keep seedbed surfaces moist  after planting to reduce soil crusting and to lower soil temperatures.  Phosphoric acid (24% and 12%) and sulfuric acid (95%) were evaluated  to determine their effectiveness in reducing soil crusting and reducing  the amount of water required to obtain stands of sugarbeets, alfalfa,  wheat and barley.  Phosphoric acid, applied in 4-6 cm bands over the seed row at  planting and before irrigation, reduced crusting and increased sugarbeet  and alfalfa seedling emergence....

Ethanol production of semi-simultaneous saccharification and fermentation from mixture of cotton gin waste and recycled paper sludge
Provedor de dados: 18
Autores: Shen, Jiacheng, J.; Foster, A.A., A.A.
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. The analysis of the reaction rates of cellobiose, glucose, cell, and ethanol using the model and the parameters from...

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...

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...

Copper Sulfate Foot Baths on Dairies and Crop Toxicities – What are the Risks?
Provedor de dados: 18
Autores: Moore, A.; Ippolito, J.A.
A rising concern with the application of dairy wastes to agricultural fields is the accumulation of   copper (Cu) in the soil. Copper   sulfate (CuSO4) from cattle foot   baths are washed out of dairy   barns and into wastewater lagoons. The addition of CuSO4   baths has been reported to increase Cu concentration significantly in manure slurry from 4.8   g/1000 L to 88.6 g/1000 L (Miner   Institute, New York). The Cu-enriched dairy waste is then applied to agricultural crops, thus raising concerns about how soils and   plants are impacted by these Cu additions.

Fate and Transport of Bioaerosols Associated with Livestock Operations and Manure
Provedor de dados: 18
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...

Recommending Soil Copper Thresholds for Potato Production in Idaho
Provedor de dados: 18
Autores: Moore, Amber; Satterwhite , Megan; Ippolito, J.A.
A rising concern with the application of dairy wastes to agricultural fields is the accumulation of copper in the soil. Copper sulfate from cattle footbaths is washed out of dairy barns and into wastewater lagoons. Potato growers are concerned about this issue, as many of the predominant dairy producing areas in Southern Idaho are also in Idaho’s established potato production regions. The objective of this project was to evaluate potato growth and copper plant uptake for potatoes grown under low, moderate, and excessively high soil copper concentrations. This study was conducted in 2011 in a greenhouse setting at the USDA ARS Kimberly Research Station. To establish an effective copper response curve, 6 rates of copper sulfate (0, 100, 200, 300, 400, and...

Technologies to minimize water quality impacts of irrigated agriculture
Provedor de dados: 18
Autores: Bjorneberg, D.L.; Sojka, R.E.; Leytem, A.B.
Irrigation transformed arid land in the Pacific Northwest into productive agricultural  land. However, much of this land is prone to erosion during irrigation, which can  cause problems on and off of the field. Management practices have been developed to  control soil erosion on irrigated land and improve the quality of water returning to  streams and rivers. Applying polyacrylamide (PAM) with irrigation water can reduce  erosion from furrow irrigated fields more than 90%. Using PAM in combination with  other practices, such as applying straw mulch in furrows and installing small  sediment ponds on fields, can virtually eliminate sediment loss from fields. Once soil  runs off a field, it can be removed by settling in sediment ponds, although soluble...

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...

Copper sulfate foot baths are a management practice used by dairy farms in an effort to control hoof infections. As an unintended consequence, agricultural soils experience Cu accumulation when spent foot baths are disposed of in wastewater lagoons that are utilized for irrigation purposes.  We investigated the effect of Cu applications (up to 1000 mg/kg) to a Xeric Haplocalcid (Declo series) and a Typic Calciaquoll (Logan series) on alfalfa (Medicago sativa) growth and Cu concentration, soil total and diethylenetriaminepentaacetic acid (DTPA)-extractable Cu, and the soil microbial community diversity using ribosomal intergenic spacer analysis (RISA).  Copper application up to 250 mg/kg did not affect alfalfa growth; above 500 mg/kg alfalfa did not grow....

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...

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...

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...

Autores: Massee, T.W.; Romanko, R.R.; Osgood, C.E.
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...

Sugarbeet
Provedor de dados: 18
Autores: Panella, Leonard W.; Kaffka, Stephen R.; Lewellen, R.T.; McGrath, J. Mitchell; Metzger, Mike S.; Strausbaugh, C.A.
Sugarbeet (Beta vulgaris L. subsp. vulgaris) is an industrial crop grown commercially as a hybrid, with sucrose refined from the root as the plant constituent of interest. Yield of refined white sugar produced per unit area is a complex trait. Sugar yield is calculated by the root weight times the proportion of root that is sucrose, minus the amount of sucrose lost during processing, often expressed as percent loss to molasses or juice purity. Yields have risen in the last 100 yr from about 10% sucrose and 22.4 Mg ha−1 (10 t ac−1) to 18% sucrose and more than 65 Mg ha−1 (29.3 t ac−1). There also has been a shift in acreage from the western United States (especially California and Colorado) to the northern Midwest (Red River Valley). Although not all of...

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...

Commercial sugar beet hybrids were evaluated for resistance to Beet severe curly top virus in a furrow-irrigated sugar  beet field near Ontario, OR where curly top had been a problem in previous years. The field trial relied on natural infection  and was planted on 6 Apr. Plots were planted to a density of 285,120 seeds/A, and thinned to 40,731 plants/A. Plots were  four rows wide (22 in. between rows) and 23 ft long. The experimental design was a randomized complete block with eight  replications. The crop was managed according to standard cultural practices. The weather during the growing season was  normal except for above average temperatures in Mar and Aug and above average precipitation in Apr and May. Disease  pressure was uniform and moderately...

Beet curly top resistance in USDA-ARS Kimberly germplasm lines, 2015
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Eujayl, I.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 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)....

Experimental 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, 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,...

Characterization of a Basidiomycete Fungus from Stored Sugar Beet Roots
Provedor de dados: 18
Autores: Toda, T; Strausbaugh, C.A.; Rodriguez-Carres, M; Cubeta, M.A.
Eighteen isolates sampled from sugar beet roots associated with an unknown etiology were characterized based on observations of morphological characters, hyphal growth at temperatures ranging from 4 to 28 C, production of phenol oxidases, and sequence analysis of internal transcribed spacer (ITS) and large subunit (LSU) regions of the ribosomal DNA (rDNA).  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...

Autores: Ippolito, J.A.; Strawn, D.G.; Scheckel, K.G.; Novak M, J; Ahmedna, M.; Niandou, M.A.S.
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...

Organic Waste Nitrogen and Phosphorus Dynamics Under Dryland Agroecosystems
Provedor de dados: 18
Autores: Ippolito, J.A.; Barbarick, K.A.
Organic waste beneficial-use programs effectively recycle plant nutrients when applied at agronomic rates. Plant-nutrient availability, transport, and fate questions have arisen when organic wastes such as biosolids have been applied to dryland agroecosystems. What is the Nfertilizer equivalency of biosolids? What is the N mineralization rate of biosolids over periods of excess moisture or drought, and over long periods of time? Would biosolids, applied at an agronomic N rate for dryland winter wheat (Triticum aestivum L.), oversupply P? If overapplication occurred, what would the repercussions be in terms of excess soil P? Our objectives were to determine: biosolids N fertilizer equivalency; biosolids N mineralization during years of above and below...

Soil-plant-microbial relations in hydrothermally altered soils of Northern California

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)...

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,...

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...

Evapotranspiration and Soil Moisture-Fertilizer Interrelations with Irrigated Winter Wheat in the Southern High Plains
Provedor de dados: 18
Autores: Jensen, M.E.; Sletten, W.H.
Irrigated and dry/and winter wheat is one of  the major crops produced in the High Plains of  Texas. As reported by the U.S. Census of Agriculture  the acreages of irrigated wheat harvested  in the High Plains in 1950, 1954, and 1959 were  133,000, 179,000 and 380,000 acres, respectively.  Additional irrigated wheat is used only for grazing  purposes. The major part of the irrigated  winter wheat harvested in the mid-1950's was in  Castro, Deaf Smith, Floyd, Hale, Parmer, and  Swisher Counties. The soils in these counties consist  mostly of clay looms and silty clay loams. Continued expansion in irrigated wheat  acreage has occurred since 1959, especially north  of the Canadian River.

Growers working with manured soils o� en rely on soil test information when developing nutrient management for their crop,  especially when manure application information is unavailable. Nutrient-enriched soils, like manured soils, can trigger nutrient  de� ciencies and toxicities due to plant–soil nutrient interactions. � e goal of the study was to determine correlations between  soil test and plant tissue nutrient concentrations for irrigated corn silage crops (Zea mays L. subsp. mays) with varying nutrient  concentrations unique to dairy manure-enriched calcareous soils. Whole plant and soil samples were collected from 39 cooperator  corn silage � elds at harvest over a 2-yr period throughout the Snake River Plain region of southern Idaho. Soils were...

Autores: Panella, Leonard W.; Strausbaugh, C.A.
Twenty-two sugar beet (Beta vulgaris L.) lines from the USDA-ARS Ft. Collins sugar beet program were screened for resistance to Beet severe curly top virus (BSCTV) and other closely related Curtovirus species in 2011. Commercial cultivars Monohikari and HM PM90 were included as susceptible and resistant checks, respectively. The curly top evaluation was conducted at the USDA-ARS North Farm in Kimberly, ID which has Portneuf silt loam soil and had been in barley in 2010. The field was plowed both in the fall and the spring, fertilized (80 lb N and 120 lb P2O5/A) on 20 Apr 11, sprayed with Ethotron (2 pt/A), and roller harrowed. The germplasm was planted (density of 142,560 seeds/A) on 16 May. The plots consisted of two rows 10 ft long with 22-in row...

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...

The sustainability of modern manure management is far from certain, with many demonstrating significant limitations from the stand point of efficient use of manure resources and protection of environmental quality and human health. As demonstrated through this review, for manure management to be sustainable, a broad array of issues must be considered and addressed, all in the context of highly competitive modern livestock production systems that largely seek to minimize costs to the consumer. In the past decade there have been major innovations in the areas of land application, manure treatment and processing and in the science of understanding the impact of manure management. As a result, major opportunities exist to improve the components of manure...

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...

Comparison of atmospheric stability methods for calculating ammonia and methane emission rates with WindTrax
Provedor de dados: 18
Autores: Koehn, A.C.; Leytem, A.B.; Bjorneberg, D.L.
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...

Environmental implications of inositol phosphates in animal manures
Provedor de dados: 18
Autores: Leytem, A.B.; Maguire, R.O.
Animal production in the USA is valued at more  than $100 billion and has consolidated significantly  during the last 20 years, with a larger  number of animals being produced on an  increasingly smaller land base (Kellogg et al.,  2000). Manure generated from animal production  is currently estimated to exceed 335 million t  of dry matter per year in the USA, while global  manure production is estimated at —13 billion t  of dry matter per year (Mullins et al., 2005).  Manures contain significant amounts of phosphorus,  with values between 6.7 and 29.1 g P/kg on  a dry weight basis reported for several species  of animals (Barnett, 1994). This phosphorus  includes inorganic and organic forms, with the  latter constituting between 10°/a and 80% of the...

Infiltration Model for Center Pivot Sprinkler Irrigation
Provedor de dados: 18
Autores: King, Bradley 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...

Autores: Gillen, A.M.; Strausbaugh, C.A.; Gallian, J.
Thirty-one sugar beet germplasm breeding lines and releases produced by the USDA-ARS sugarbeet  program at Salinas, CA, and one line from the USDA-ARS sugarbeet program at East Lansing, MI, were  evaluated for resistance to rhizomania under south-central Idaho conditions at Twin Falls, ID. The field had been  identified as having Beet necrotic yellow vein virus (BNYVV), which overcomes resistance conditioned by the  Rzl gene. Single-row plots 10 ft long with 22-in. spacing were planted on 23 May 05. Plants were thinned to 4 to  6-in. spacing in mid-Jun. The materials were predominantly multigerm; they were hand thinned to single plants  during the first week of Jul.

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...

Groundwater use on southern Idaho dairies
Provedor de dados: 18
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,...

Factors Affecting Curly Top Damage to Sugarbeets and Beans in Southern Idaho, 1919-1977
Provedor de dados: 18
Autores: Blickenstaff, C.C.; Traveller, Del.
Curly top, a virus disease transmitted only by the beet  leafhopper, was a serious threat to the sugarbeet industry  in south-central Idaho from 1919 through 1941 and to dry  edible and snap bean production from 1924 through 1957. The  frequency and severity of damage are charted from 1919  through 1977. The development of plant varieties resistant  to curly top is attributed as the major factor in lessening  damage to sugarbeets since 1942; the development of plant  resistance in beans proceeded at a slower rate, but has also  become a major factor in lessening damage. Other possible  factors discussed are: (1) size of overwintering beet leafhopper  populations, (2) early spring migration of beet leafhoppers,  (3) insecticidal control in desert areas, (4)...

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.

Water returning to a river from an irrigated watershed could increase the water temperature in the river. The objective of this study was to compare the temperature of irrigation return flow water with the temperature of the diverted irrigation water. Water temperature was measured weekly in the main irrigation canal, 24 return flow streams and one ephemeral stream from 2005 to 2008 in the Upper Snake Rock (USR) watershed. The USR is an 82,000 ha watershed in southern Idaho, USA with about 60% of the area surface irrigated and the remaining area sprinkler irrigated. Median annual water temperatures in irrigation return flow streams were not greater than the water diverted from the river, suggesting that water flowing through the canal system and furrow...

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.

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...

The effectiveness of recovered magnesium phosphates as fertilizers in neutral and slightly alkaline soils
Provedor de dados: 18
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...

Autores: Strausbaugh, C.A.; Eujayl, Imad A.; Rearick, E.
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, 26 experimental cultivars were screened by growing them in a sugar beet field infested with BNYVV in Kimberly, ID during the 2012 growing season in a randomized complete block design with 4 replications. At harvest on 3 October 2012, roots were dug and evaluated for symptoms of rhizomania and also placed in an indoor commercial sugar beet storage building.  After 134 days in storage, samples were evaluated for surface rot, weight loss, and sucrose loss. Surface root rot ranged from 34 to 90%, weight loss ranged from 8.4 to 15.4%, sucrose losses ranged...

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...

Virulence, Distribution and Diversity of Rhizoctonia Solani from Sugar Beet in Idaho and Oregon
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Eujayl, Imad A.; Panella, Leonard W.; Hanson, Linda E.
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,...

Evaluation of neural network modeing to calculate well-watered leaf temperature of wine grape
Provedor de dados: 18
Autores: King, B.A.; Shellie, Krista.
Mild to moderate water stress is desirable in wine grape for controlling vine vigor and optimizing fruit yield and quality, but precision irrigation management is hindered by the lack of a reliable method to easily quantify and monitor vine water status. The 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, a daily CWSI for the wine grape cultivar Syrah was calculated by estimating well-watered leaf temperature with an artificial neural network (NN) model and non-transpiring leaf temperature based on the cumulative probability of the measured difference...

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...

Autores: Leytem, A.B.; Dungan, R.S.
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...

Removal of vegtative clippings reduces dissolved phosphorus loss in runoff
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...

Phosphorus Fertility Relationships of Central Washington Irrigated Soils (with special emphasis on exposed calcareous subsoils)
Provedor de dados: 18
Autores: James, D.W.; Leggett, G.E.; Dow, A.I.
To facilitate irrigation in central Washington, land  is leveled or smoothed on a broad scale. As a result, the  calcareous and extremely infertile subsoils are exposed  and used directly as a medium for plant growth. Phosphorus  fertilizer requirements of exposed subsoils were  determined by measuring crop yield and P uptake on  plots that were fertilized in the current and one, two  or three preceding seasons. Annual crops used as indicators  of P availability at three sites were field beans,  Sudangrass and sugar beets. A supplementary experiment  involved fertilization of a previously established  alfalfa crop. Crop growth and P uptake results were  correlated with sodium bicarbonate soil testing

Comparison of sprinkler droplet size and velocity measurements using a laser precipitation meter and photographic method
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. A laser precipitation meter and photographic method were used to measure droplet size and velocity from an impact sprinkler at three pressures and one nozzle size. 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 velocities were found between measurement methods as...

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).  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),...

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...

The rate of advance is governed by the  intake rate of the soil, the resistance offered by  the channels to the flow of water, and the discharge  rate into the channels. A knowledge of these  factors is essential for the design of efficient irrigation  systems. Intake rate has been the object  of much study and methods are available for its  measurement before the construction of irrigation  systems. Previous flow resistance studies have  dealt with either artificially roughened boundaries,  conduits intended for uses other than irrigation,  or discharges much greater than are likely to  occur in...

This study was conducted to determine the effect of biosolids and lime on reclamation of a heavily contaminated metal site.  Within the Superfund area near Leadville, CO, biosolids and lime were amended (1998) to a 1 ha site at rates of 240 Mg per ha each.  In 2006, soil samples were collected on a 10 m x 10 m grid to a depth of 30 cm across the site.  Basic soil analysis included pH, EC, total C and N, inorganic and organic C, and NO3-N and NH4-N.  A sequential fractionation for metal contaminants of concern (Cd, Cr, Fe, Pb, Mn, and Zn) identified associations with: 1) soluble/exchangeable; 2) specifically sorbed/weakly bound; 3) non-crystalline Fe/Mn oxides; 4) crystalline Fe/Mn oxides and organically complexed; 5) residual organic; and 6) residual...

Insecticide seed treatments for sugarbeet
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Eujayl, I.A.; Foote, P.
Pest feeding and vectoring of viruses cause serious problems in sugarbeet production worldwide. In order to ameliorate pest 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 eight field trials from 2006 to 2008 along with various commercial sugarbeet cultivars in a randomized complete block design with eight replications per trial.  Natural pest incidence and curly top symptoms were evaluated.  Both Poncho Beta and Cruiser Tef provided significant reduction...

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...

Conservation practice effectiveness in the irrigated Upper Snake/Rock Creek watershed
Provedor de dados: 18
Autores: Bjorneberg, D.L.; Westermann, D.T.; Nelson, N.O.; Kendrick, J.H.
The Upper Snake River/Rock Creek Conservation Effects Assessment Project was initiated in 2005 to determine the effectiveness of conservation practices in an irrigated watershed. Our objectives were to determine water and salt balances and water quality effects of using sprinkler rather than furrow irrigation in the Twin Falls irrigation tract in southern Idaho. Data from the current study were compared with earlier studies conducted from 1968 to 1971. Irrigation water diverted from the Snake River supplied 73% and 83% of the hydrologic input to this 82,000 ha (202,000 ac) watershed in 2005 and 2006, respectively, with approximately 40% flowing back to the Snake River through furrow irrigation runoff, unused irrigation water, and subsurface drainage.

Provedor de dados: 18
Autores: Lehrsch, G.A.; Brown, B.; Lentz, R.D.; Johnson-Maynard, J.L.; Leytem, A.B.
To maximize recoverable sucrose from sugarbeet (Beta vulgaris L.), producers must effectively manage added nitrogen (N), whether it be from urea or organic sources such as manure or composted manure.  Our multi-site study’s objective was to determine the effects of a one-time application of stockpiled and composted dairy cattle manure on sugarbeet N uptake, N recovery (NR) and N use efficiency (NUE).  First-year treatments at Site 1 included a control (no N), urea (202 kg N/ha), compost (218 and 435 kg estimated available N/ha), and manure (140 and 280 kg available N/ha).  Site 2 treatments were a control, urea (82 kg N/ha), compost (81 and 183 kg available N/ha), and manure (173 and 340 kg available N/ha).  Compost and manure were incorporated into two...

The Current State of Predicting Furrow Irrigation Erosion
Provedor de dados: 18
Autores: Bjorneberg, D.L.; Strelkoff, T.; Clemmens, A.J.; Lee, J.H.
There continues to be a need to predict furrow irrigation erosion to estimate on- and off-site impacts of irrigation management. The objective of this paper is to review the current state of furrow erosion prediction technology considering four models: SISL, WEPP, WinSRFR and APEX. SISL is an empirical model for predicting annual soil loss from furrow irrigated fields. SISL could potentially be a useful model if a new method was developed to calculate base soil loss for areas other than southern Idaho where it was developed. The WEPP model uses physically-based equations to predict erosion in irrigation furrows, which are assumed to be the same as rills. Primary difficulties with the WEPP model are defining erodibility parameters for furrow irrigation 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.

Autores: Sojka, R.E.; Entry, J.A.
We compared the efficacy of matrix based fertilizers (MBFs) formulated to reduce NO 3 -,  NH4+ , and total phosphorus (TP) leaching, with Osmocoate® 14-14-14, a conventional  commercial slow release fertilizer (SRF), and with an unamended control in greenhouse  column studies. The MBF formulations covered a range of inorganic N and P in compounds  that are relatively loosely bound (MBF1) to more moderately bound (MBF2) and more tightly  bound compounds (MBF3) mixed with Al(SO 4)3 H2O and/or Fe2(SO4 )3 and with high ionic  exchange compounds starch, chitosan and lignin. When N and P are released, the chemicals  containing these nutrients in the MBF temporarily bind N and P to a Al(SO4 )3 H2O and/or  Fe2(SO4 )3 starch- chitosan- lignin matrix. One milligram...

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...

Organic carbon in soil decreased in the order IP&gt;ICT&gt;NSB&gt;IMP. We use our findings to estimate the organic carbon, potentially sequestered if the use of irrigated agriculture were increased.  We also use our findings to estimate inorganic and total carbon, potentially sequestered if the use of irrigated...

Autores: Panella, Leonard W.; Strausbaugh, C.A.
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. The experimental design was a randomized complete block design with eight replications per entry. The crop was managed according to standard cultural practices, except for...

Droplet Kinetic Energy from Center-Pivot Sprinklers
Provedor de dados: 18
Autores: King, B.A.; Bjorneberg, D.L.
The kinetic energy of discrete water 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 the seasonal runoff and erosion hazard. The size and velocity of drops from common rotating spray-plate sprinklers center-pivot sprinklers with flow rates of  approximately 40 and 20 L/ min were measured using a laser in the laboratory. The data were used to...

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...

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.

Soil ingestion by ungulates grazing a sagebrush-bunchgrass range in Eastern Oregon
Provedor de dados: 18
Autores: Sneva, Forrest A.; Mayland, H.F.; Vavra, M.
Ingested soil by the grazing animal not only contributes to the wear  of the animal's teeth, but may also be a source of dietary minerals. Thus,  an estimate of soil intake is a necessary factor in the determination of  the amount of minerals entering the animal via the soil.  Titanium (Ti), a rare earth element, is relatively abundant in soils,  but is found only in small quantities (1 part per million) in plants not  contaminated with soil (Healy, 1968). Thus, its presence in the feces of  grazing animals is a reflection of: (1) eating soil-contaminated forage;  (2) ingesting soil directly; (3) drinking soil-contaminated water. Mayland  et al. (1975) investigated the Ti method in Idaho and found it useful for  estimating soil ingestion by cattle grazing...

Manure and fertilizer effects on carbon balance and organic and inorganic carbon losses for an irrigated corn field
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.

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.

The effects of biochar and manure in silage corn
Provedor de dados: 18

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...

Copper Sequestration Using Local Waste Products
Provedor de dados: 18
Autores: Ippolito, J.A.
Dairies utilize copper sulfate (CuSO4) foot baths to control hoof infections. Typical   solutions are 5 or 10% CuSO4 (pH ~6), equal to 12,500 or 25,000 ppm Cu, respectively. When   spent, hoof bath solutions are usually disposed of in waste lagoons and subsequently utilized for   irrigation. In the Magic Valley, this practice appears to be causing soil Cu concentrations to   increase. The goal of our research was to use local waste products to sequester Cu from a   simulated hoof bath solution and to use waste products to adsorb excessive Cu from Cu-affected   soils.          We utilized lime waste and fly ash from the Amalgamated Sugar Company, LLC (Twin   Falls, ID) to identify Cu sorption maximum as a function of pH. In triplicate, solutions...

sugar beet germplasm evaluated for resistance to rhizomania and fungal growth in storage in Idaho, 2011.
Provedor de dados: 18
Autores: Eujayl, Imad A.; Strausbaugh, C.A.
Resistance to rhizomania is a basic requirement for cultivars’ approval for commercialization. The objectives of this research were to identify germplasm accessions that carry resistance genes to rhizomania and storage root rots. Twenty-one sugar beet (Beta vulgaris L.) germplasm from the USDA-ARS Kimberly sugar beet program and four check cultivars were screened for resistance to Beet necrotic yellow vein virus (BNYVV) during the 2011 growing season and during the 2011/2012 storage period for fungal growth in an indoor storage.  The rhizomania evaluation was conducted at the rhizomania nursery in the USDA-ARS North Farm in Kimberly, ID.  The crop was managed according to standard cultural practices and pest control.  The plots were rated twice (4 weeks...

One-time tillage of no-till: Effects on nutrients, mycorrhizae, and phosphorus uptake
Provedor de dados: 18
Autores: Garcia, J.P.; Wortmann, C.S.; Mamo, M.; Drijber, R.; Tarkalson, D.
Stratification of nutrient availability, especially of P, that develops  with continuous no-till (NT) can affect runoff nutrient concentration  and possibly nutrient uptake. The effects of composted manure application  and one-time tillage of NT on the distribution of soil chemical  properties, root colonization by arbuscular mycorrhizae (AM), and  plant P uptake were determined. Research was conducted on Typic  Argiudoll and Moffic Hapludaff soils under rainfed corn (Zea mays L.)  or sorghum [Sorghum bicolor (L.) Moench.] rotated with soybean  [Glycine max (L.) Men.] in eastern Nebraska. Tillage treatments included  NT, disk, chisel, moldboard plow (MP), and mini-moldboard  plow (MMP). Subplots had either 0 or 87.4 kg P ha -I- applied in compost  before...

Nitrogen placement, row spacing, and water management for furrow-irrigated field corn
Provedor de dados: 18
Autores: Lehrsch, G.; Sojka, R.; Westermann, D.
Banding and sidedressing nitrogen (N) fertilizer on a never-irrigated side of a row of corn  (Zea mays L.) were hypothesized to maintain yield and decrease nitrate leaching. In a two—year  ?eld study on a Portneuf silt loam (Durinodic Xeric Haplocalcid) in southern Idaho, we  evaluated effects on yield and N uptake of 1) urea placement (broadcast pre-plant vs. band at  planting), 2) row spacings (30-in vs. an offset 22—in spacing in which every pair of 22-—in rows  was positioned close to a furrow rather than each row on a bed center), and 3) water  management. Our water management, termed irrigated furrow positioning, consisted of every-  second furrow irrigation in which we applied water to either a) the same or b) the Opposite side  of the row with...

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 =...

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...

Dairy manure/compost N release for sugarbeets and subsequent wheat
Provedor de dados: 18
Autores: Brown, B.; Johnson-Maynard, J.; Leytem, A.; Lentz, R.; Lehrsch, G.
There is frequently more manure generated than can be environmentally applied in a sound  manner within the limited land resources of the growing number of Idaho dairies and feedlot  operations. There is considerable incentive to export manure or compost from these operations  to nearby farmer fields. Manure composting is currently used to reduce the volume of material  hauled. But the slower release nature of organic N sources could be problematic for sugarbeets  if the timing of N release interferes with late season sugarbeet growth and sugar content. A  better understanding of the N release dynamics from manures and composts is needed to know  how best to use these resources without causing excessive available N at the end of the season,  the associated...

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 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...

Sprinkler pattern analysis for center pivot irrigation
Provedor de dados: 18
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%...

Autores: Moore, Amber; Tarkalson, D.D.
Decomposition rates directly affect carbon and nitrogen ratios, which can affect nitrogen mineralization rates. The objective of this research is to determine the effect of tillage method and nitrogen rate on nitrogen available to sugar beets planted after a cereal crop. This two-year field study conducted in Kimberly, Idaho, consisted of three tillage methods (moldboard plow, chisel plow, and strip tillage), two tillage timings (fall and spring), and four fertilizer N rates plus a control. Soils from each plot were sampled shortly after nitrogen fertilization and incubated at average seasonal temperatures for Kimberly, Idaho to monitor nitrogen mineralization patterns. In 2008, we found that at N fertilizer rates of 0, 50, and 100 lbs N per acre,...

The marked reduction in infiltration rate caused by formation of a soil surface seal is a well known phenomenon but often ignored in infiltration models. The effect sequential water application events have on infiltration rate and soil surface seal formation has rarely been investigated. The objective of this study was to investigate the effect sequential water application events have on the infiltration rate of a Portneuf silt loam soil with and without water droplet impact. The Portneuf silt loam soil developed a soil surface seal that reduced infiltration rate both with and without droplet impact on the bare soil surface. When the soil surface was protected during the first rainfall event, drying the soil did not increase infiltration rate for...

Site-Specific Nematode Management for Potatoes in Idaho Using 1,3-Dichloropropene; Experiences and Economics
Provedor de dados: 18
Autores: King, Bradley A.
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. From 2002 through 2008, 62 commercial potato fields in eastern Idaho were field tested using geo-referenced grid soil sampling 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 samples had Columbia...

Autores: Dungan, R.S.; Leytem, A.B.
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...

Surfactant effects on the water-stable aggregation of wettable soils from the continental USA
Provedor de dados: 18
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...

Autores: Wortmann, C.C.; Shapiro, C.A.; Dobermann, Achim; Ferguson, Richard; Hergert, G; Walters, Daniel; Tarkalson, D.D.
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...

Small Grain Residue Management Effects on Soil Organic Carbon:  A Literature Review
Provedor de dados: 18
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...

Effects of a new polysaccharide-based amendment on furrow irrigation infiltration and erosion
Provedor de dados: 18
Autores: Bjorneberg, D.L.; Sojka, R.E.
Controlling soil erosion on furrow?irrigated fields is essential to maintain productivity and reduce off?site impacts.  Identifying effective alternatives to polyacrylamide (PAM) is desired for continued, affordable irrigation erosion control. We  compared the effectiveness of a new polysaccharide/PAM amendment with water?soluble, high molecular weight, anionic  PAM in two furrow?irrigated field tests in southern Idaho. Test 1 evaluated three rates of the polysaccharide/PAM amendment  (6, 12, and 18 mg L-1 of polysaccharide/PAM), two rates of PAM (2 and 10 mg L-1 of PAM), 10 mg L-1 polysaccharide, and  a control during two irrigations in a fallow field. Treatments were applied as a solution with furrow inflow water during  irrigation advance. Test 1...

Evapotranspiration and Soil Moisture-Fertilizer Interrelations with Irrigated Grain Sorghum in the Southern High Plains
Provedor de dados: 18
Autores: Jensen, M.E.; Sletten, W.H.
In 1956 and 1957 grain sorghum represented  37 percent of the harvested crop acreage in Texas. The largest concentrated area of sorghum  is in the High Plains where the proportion of  sorghum irrigated increased greatly during the  drought years of the 1950's. In 1959 the monetary  value of irrigated grain sorghum was estimated  to be about $100 million.  As reported by the U.S. Census of Agriculture  the acreages of irrigated grain sorghum harvested  in the 42-county High Plains area in 1950, 1954,  and 1959 were 387,000, 1 1 006,000, and 1,224,000  acres, respectively. The irrigated grain sorghum  acreage in the eight counties—Castro, Deaf  Smith, Floyd, Hale, Lamb, Lubbock, Farmer,  and Swisher—represented over 80 percent of the  total in the High...

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...

Clinoptilolite Zeolite Influence on Nitrogen in a Manure-Amended Sandy Agricultural Soil
Provedor de dados: 18
Autores: Tarkalson, D.D.; Ippolito, J.A.
Development of best management practices can help improve inorganic nitrogen (N) availability to plants and reduce nitrate-nitrogen (NO3-N) leaching in soils. This study was conducted to determine the influence of the zeolite mineral clinoptilolite (CL) additions on NO3-N and ammonium-nitrogen (NH4-N) in two common Pacific Northwest soils. The effects of CL application rate (up to 26.9 Mg ha-1) either band applied or mixed with a set rate of N fertilizer on masses of NO3-N and NH4-N in leachate and soil were investigated in a column study using a Portneuf silt loam (coarse-silty mixed mesic Durixerollic Caliciorthid) and a Wolverine sand (Mixed, frigid Xeric Torripsamment). All treatments for each soil received a uniform application of N from urea...

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,...

Autores: Strausbaugh, C.A.; Gillen, A.M.
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%...

Autores: Dungan, R.S.; Leytem, A.B.
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...

We compared the efficacy of matrix based fertilizers (MBFs) formulated to reduce NO3-, NH4+, and total phosphorus (TP) leaching, with Osmocoate 14-14-14, a conventional commercial slow release fertilizer (SRF) and an unamended control in three different soil textures in a greenhouse column study. The MBFs covered a range of inorganic N and P in compounds that are relatively loosely bound (MBF 1) to more moderately bound (MBF 2) and more tightly bound compounds (MBF 3) mixed with Al(SO4)3H2O and/or Fe2(SO4)3 and with high ionic exchange compounds starch, chitosan and lignin. When N and P are released, the chemicals containing these nutrients in the MBF bind N and P to a Al(SO4)3H2O and/or Fe2(SO4)3 starch-chitosan-lignin matrix. One milligram (8000 spores)...

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...

Comparison of fall and spring bedding for furrow irrigated potatoes following fall moldboard or chisel plowing
Provedor de dados: 18
Autores: Shock, C.; Stieber, T.; Eldredge, E.; Sojka, R.; Kennedy-Ketcheson, E.
The decision to fall or spring bed potatoes is often dictated by weather and  processor contract agreements. Although there are advantages to both fall an(  spring bedding, soil conditions are often wet in the spring in Malheur County,  Oregon. Spring bedding of wet soils leads to soil compaction and decreased  water infiltration. The primary objective of the study was to determine the  effects of fall or spring bedding on tuber yields and quality under furrow  irrigation.  Determining the most effective method of fall potato ground preparation was  the second objective of the trial. Land for potato production is normally  moldboard plowed in the fall. Chisel plowing may provide better placement of  residues in bedded ground and thus promote higher...

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...

Verticillium wilt in experimental sugar beet cultivars in Cassia County, ID, 2006
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...

Copper Sequestration Using Local Waste Products
Provedor de dados: 18
Autores: Ippolito, J.A.
Dairies utilize copper sulfate   (CuSO4) foot baths to control hoof   infections. Typical solutions are 5 or   10% CuSO4 (pH ~6), equal to 12,500   or 25,000 ppm Cu, respectively.   When spent, hoof bath solutions are   usually disposed of in waste lagoons   and subsequently utilized for irrigation. In the Magic Valley, this practice   appears to be causing soil Cu concentrations to increase. The goal of   our research was to use local waste   products to sequester Cu from a   simulated hoof bath solution and to   use waste products to adsorb excessive Cu from Cu-affected soils.

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...

Provedor de dados: 18
Autores: Strausbaugh, C.A.; Gillen, A.M.; Camp, S.; Shock, C.C.; Eldredge, E.P.; Gallian, J.J.
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,...

The absorbed phosphate moves upward  and downward in the plant. Phosphorus-deficient potato  plants transfer P from older tissues to actively growing,  younger tissues.  Symptoms of P deficiency include darker green, stunted,  spindly leaves with younger leaflets that turn upward  or curl. With prolonged deficiency, plants are  small and have reduced leaf area.

Decomposition of Bt and non-Bt corn hybrid residues in the field. Nutrient Cycling in Agroecosystems
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)...

Drought tolerance selection of sugarbeet hybrids
Provedor de dados: 18
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.

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...

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,...

Although improved tillage practices, application of commercial fertilizers, and improved crop varieties have raised the general production level in the Upper Snake River dryfarming areas, the benefits realized from these advances are generally limited by moisture supply. The has been demonstrated by the wide range of crop yields associated with year-to-year fluctuations in stored soil moisture and precipitation.

Autores: Moore, Amber; Hines, Steve; Brown, B.; de Haro Marti, Mario; Falen, Christi; Chahine, Mireille; Fife, Tianna; Norell, Rick; Ippolito, J.A.
Corn silage is the predominant crop in Idaho used for   recovering phosphorus (P) that has accumulated in soils   from dairy manure applications. However, little is known   about how much P and other nutrients are being recov-  ered under Idaho conditions. The objective of the study   is to estimate P removal by irrigated corn silage crops   cultivated throughout southern Idaho with variable soil   test P concentrations, and to identify effects of increasing soil test P on tissue concentrations of P and on plant  P uptake.        Forty-two different corn silage fields in 2008 and   2009 were selected throughout southern Idaho for soil   and whole plant sampling at harvest. Soils were ana-  lyzed for Olsen P, plant tissue was measured for total P  content,...

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...

Aggregate tensile strength and friability characteristics of furrow and sprinkler irrigated fields in Southern Idaho
Provedor de dados: 18
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...

Environmental Benefits of Biochar
Provedor de dados: 18
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).

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...

Manure and fertilizer effects on carbon balance and organic and inorganic carbon losses for an irrigated corn field

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)...

Of 53 chemicals tested in  the laboratory, 24 showed effectiveness approximately equal to or  better than DDT or carbaryl, which were used as standards. Of 26 materials  applied as sprays to beans with ground equipment, 7 that were  tested most extensively indicate effectiveness equal to or better than  carbaryl, and 9 tested less extensively .indicate a high degree of effectiveness.  Of those materials applied by air to sweet corn, permethrin  provided almost perfect control, Three formulations of carbaryl did  not differ significantly in performance in individual tests, but the...

Economic Decisions in Producing Irrigated Grain Sorghum on the Northern High Plains of Texas
Provedor de dados: 18
Autores: Wehrly, J.S.; Sletten, W.H.; Jensen, M.E.
American farmers have a wealth of research data  available to them. Much of the data is concerned  with technical problems of increasing yields, improving  quality and reducing costs. In nearly all instances  the improved practices can be applied by a farmer  only at a cost. The farmer must decide if the improvement  in output, quality or efficiency is enough  to justify the extra cost, or more likely, must decide  to what extent these practices should be applied. The  extent to which any single agricultural input should  be used cannot be determined without considering  the use and effect of other inputs and the costs of  all inputs and the price of the product.  This publication is concerned with the amounts  of nitrogen and irrigation water to use in...

Provedor de dados: 18
Autores: Eujayl, Imad A.; Strausbaugh, C.A.
Sugar beet germplasm, wild beta, and commercial check cultivars were evaluated in a commercial  field (near Declo, ID ). This field was sprinkler-irrigated and winter wheat was grown in the previous year.  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 15 Apr 08 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. The experimental design was a randomized complete  block design with eight replications per entry. The field was cultivated on 13 Jun 08. The crop was  managed by the grower according to standard...

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...

Effects of Alfalfa, Crop Sequence, and Tillage Practice on Intake Rates of Pullman Silty Clay Loam and Grain Yields
Provedor de dados: 18
Autores: Jensen, M.E.; Sletten, W.H.
The High Plains of Texas is one of the largest irrigated areas in the  United States. Most of the 5.7 million acres irrigated in Texas  (1959 census) is concentrated in the High Plains. The area is unique  because most of the irrigated land is of one soil series-Pullman.  Pullman soils represent over 5 million acres of the “hardlands” in the  Southern High Plains of Texas, New Mexico, and Oklahoma.  The term “hardlands” is used extensively when referring to the  High Plains because of the soil characteristics of the area. The soils  are mostly clay loams and silty clay loams. The have low intake  rates, are dense, and become very hard and difficult to till when dry.  The differences between the clay loams and silty clay loams are  minor. The physical...

Macroscopic and microscopic variation in recovered magnesium phosphate materials: Implications for phosphorus removal processes and product re-use
Provedor de dados: 18
Autores: Massey, M.S.; Ippolito, J.A.; Davis, J.G.; Sheffield, R.E.
Phosphorus (P) recovery and re-use will become increasingly important for water quality protection and  sustainable nutrient cycling as environmental regulations become stricter and global P reserves decline.  The objective of this study was to examine and characterize several magnesium phosphates recovered  from actual wastewater under field conditions. Three types of particles were examined including crystalline  magnesium ammonium phosphate hexahydrate (struvite) recovered from dairy wastewater, crystalline  magnesium ammonium phosphate hydrate (dittmarite) recovered from a food processing facility,  and a heterogeneous product also recovered from dairy wastewater. The particles were analyzed using  ‘‘wet” chemical techniques, powder X-ray diffraction...

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.

Autores: Tarkalson, D.D.; Bjorneberg, D.L.; Hines, Steve.
Funding is being sought from multiple sources to update nitrogen fertilizer recommendations for irrigated corn in southern Idaho and southwest Oregon. This paper summarizes the justifications and main objectives of this proposed research. Nitrogen needs to be correctly managed in corn production systems to optimize economic returns and to protect the environment. The fertilizer nitrogen recommendations for irrigated field corn in Idaho and other parts of the Pacific need to be re-evaluated because: (1) University of Idaho (U of I) and PNW region recommendations are based on sparse research data; (2) Recommendation are based on research data that is over 25 years old; (3) Corn production area and yield have increased dramatically in concentrated areas due...

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...

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. Bromide (Br) was used as a conservative tracer to determine dilution effects. Water was sampled at 10-minute intervals, beginning 30...

Management of irrigated agriculture to increase organic carbon storage in soils
Provedor de dados: 18
Autores: Entry, J.A.; Sojka, R.E.; Shewmaker, G.E.
Increasing the amount of C in soils may be one method to reduce the concentration of  C02 in the atmosphere. We measured organic C stored in southern Idaho soils having long  term cropping histories that supported native sagebrush vegetation (N SB), irrigated moldboard  plowed crops (IMP), irrigated conservation -chisel- tilled crops (ICT) and irrigated pasture  systems (1?). The C02 emitted as a result of fertilizer production, farm operations and CO;  lost via dissolved carbonate in irrigation water, over a 30 year period, was included. Net  organic C in ecosystems decreased in the order IP&gt;ICT&gt;NSB&gt;IMP. In this study, if NSB were  converted to IMP, 0.15 g C m“2 would be emitted to the atmosphere, but if converted to IP  , 3.56 g C m'2 could be...

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...

Soil and Nutrient Losses from Small Sprinkler and Furrow Irrigated Watersheds in Southern Idaho
Provedor de dados: 18
Autores: Bjorneberg, D.L.; King, B.A.; Nelson, Nathan; Lee, J.H.
Sediment and associated nutrients flowing to the Snake River with furrow irrigation runoff and unused irrigation water have been a concern in the Twin Falls irrigation tract in southern Idaho. Converting furrow irrigated fields to sprinkler irrigation is one practice that has been promoted, and received financial assistance, to reduce sediment loss. Five small watersheds (330 to 1480 acres) with 10 to 70% sprinkler irrigation were monitored from 2005 to 2008 to determine if converting to sprinkler irrigation reduced sediment and nutrient losses from these watersheds. Eliminating runoff from furrow irrigated fields by converting to sprinkler irrigation will reduce sediment and nutrient losses from fields. However, there were no significant correlations...

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. Ross 508 broiler chicks were fed 1 of 12 diets from 16 to 21 d of age. Excreta were collected from 16 to 17 d and from 19 to 20 d of...

Advances in Data Processing for Open-path Fourier Transform Infrared Spectrometry of Greenhouse Gases.
Provedor de dados: 18
Autores: Shao, L.; Griffiths, P.R.; Leytem, A.B.
The automated quantification of three greenhouse gases, ammonia, methane and nitrous oxide, in the vicinity of a large dairy farm by open-path Fourier transform infrared (OP/FT-IR) spectrometry at intervals of 5 minutes is demonstrated.  Spectral pretreatment, including the detection and correction of the effect of interrupting the infrared beam is by a moving object, and ways of correcting for the effect, and correction for the nonlinear detector response are applied to the measured interferograms.  Two ways of obtaining quantitative data from OP/FT-IR data are described.  The first, which is installed in commercial OP/FT-IR spectrometers, is based on classical least squares (CLS) regression and the second is based on partial least squares (PLS)...

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...

Phosphorus Utilization and Characterization of Excreta From Swine Fed Diets Containing A Variety of Cereal Grains Balanced For Total Phosphorus
Provedor de dados: 18
Autores: Leytem, A.B.; Thacker, P.A.
Intrinsic phytase in swine feeds may alter phytate utilization and solubility of excreted phosphorus. Therefore, the objective of this experiment was to quantify changes in fecal phosphorus composition from swine fed various cereal grains with a range of phytate concentrations and endogenous phytase activities. Twenty-five crossbred barrows weighing 89.3 + or - 6.8 kg were fed one of five diets based on corn, barley, low phytate barley, high fat-low lignin oat or wheat. Experimental diets were formulated to contain 75% of the test grain and were fed for a seven-day acclimation period followed by a three-day fecal collection. Total tract apparent digestibility coefficients were determined for dry matter, phosphorus and phytate using the indicator method....

Water treatment residuals and biosolids coapplications affect semiarid rangeland phosphorus cycling
Provedor de dados: 18
Autores: Bayley, R.M.; Ippolito, J.A.; Stromberger, M.E.; Barbarack, K.A.; Paschke, M.W.
Land coapplication of water treatment residuals (WTR) with biosolids has not been extensively researched, but the limited studies performed suggest that WTR sorb excess biosolids-borne P. To understand the long-term effects of a single coapplication and the short-term impacts of a repeated coapplication on soil P inorganic and organic transformations, 7.5- by 15-m plots with treatments of three different WTR rates with a single biosolids rate (5, 10, and 21 Mg WTR ha-1 and 10 Mg biosolids ha-1) surface coapplied once in 1991 or surface reapplied in 2002 were utilized. Soils from the 0- to 5-cm depth were collected in 2003 and 2004 and were sequentially fractionated for inorganic and organic P (Po). Inorganic P fractionation determined (i) soluble and...

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). Treatments at Site 2 (Kimberly, ID), were a control, urea (82 kg...

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...

Reducing nutrient losses in runoff from furrow irrigation
Provedor de dados: 18
Autores: Lentz, R.D.; Westermann, D.T.; Lehrsch, G.A.
Few studies have comprehensively examined nutrient losses in runoff from furrow-irrigated fields, but the rising cost of fertilizer and finite nature of the resource encourages further research.  A 2-yr experiment measured runoff losses of sediment, particulate P and N, and dissolved NO3-N, NH4-N, K, and reactive P (DRP) from fertilized, manured, or non-amended fields.  Average nutrient losses were substantial, including 15.6 lbs ac/yr dissolved N, P, and K and 73.6 lbs ac/yr particulate N and P. The cost or replacing these nutrients with inorganic fertilizers was not trivial, at $54.69 ac/yr.  Relative to non-amended soil, manure increased dissolved K, NO3-N, and DRP in runoff by 2.1x, 1.5x, and 2.7x, respectively. Other experiments evaluated the...

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.

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),...
