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. 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 |
