1. Manure Management Practices to Limit Nutrient Loss from Frozen Agricultural FieldsManure applied to crop areas can be an importa nt source of plant nutrients for crop production and may improve soil quality. Relatively small amounts of nutrients especially phosphorus (P) from manure reaching water bodies can signifi cantly increase eutrophication and impair water quality. Most recommendations indicate not to apply manure to fro zen soils because the risk of nutrient loss to surface water may be increased. Our research objective was to determine the influence of manure application... |
2. Effect of Biosolids Application On Plant Available NutrientsBiosolids are a by-product of municipal wastewater treatment process which is extensively treated to meet all applicable federal and state regulations so that they can it can be safely applied to land. Approximately, 7.9 million dry metric tons of biosolids are produced annually in the United States (U.S.) and over 55% of this amount is beneficially utilized through land application (NEBRA, 2007). Farmland application of biosolids is considered to be one of the most economical and environmentally... |
3. Nitrogen Dynamics and Agronomic-Environmental Impacts of Annual Vs. Perennial Cover Crops in Irrigated Corn-Soybean Systems on Sandy SoilsIrrigated sandy soils can be highly productive yet vulnerable to Nitrogen (N) losses. Kura Clover (Trifolium ambiguum) living mulch offers an alternative mitigation strategy. However, there is limited research aiming to holistically compare the effect of annual vs. perennial cover crops on season-long N dynamics and agronomic-environmental impacts on corn (Zea Mays L.)-soybean [Glycine max (L.) Merr.] cropping systems. This 2-yr study assessed rye (Secale cereale) and Kura... E. Garay lagos, F. Fernández, J. Grossman , V. Sharma, R. Venterea |
