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 Late-Applied N on Corn Dry Matter, N Content, and YieldNitrogen management of corn (Zea mays L.) may be improved by delaying N application until just prior to the rapid growth phase (approximately V6-V8). This timing is commonly referred to as 'sidedress'.� Some farmers do not sidedress because they are concerned inclement weather may delay N application beyond V8, requiring high clearance equipment to apply N and possibly reducing grain yield. However, few studies have investigated the effects of late-applied N in rain-fed production environments... |
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 |
