Agronomic And Economic Implications Of Cover Crop Inclusion Within Varying Nitrogen Management Strategies In Central Illinois, Richard T. Roth
Agronomic And Economic Implications Of Cover Crop Inclusion Within Varying Nitrogen Management Strategies In Central Illinois, Richard T. Roth
Theses and Dissertations
This thesis contains a comprehensive analysis of research investigating the impacts of nitrogen application timing and cover crops on the biomass production, nitrogen uptake, and cash crop grain yield in subsequent cash crops. Also contained within this thesis is a cost benefit analysis for the implementation of cover crops within varying nitrogen management systems, which assigns value to the environmental benefits of cover crops and determines their potential to recover the implementation costs associated with cover crops.
Improving The Efficiency Of Fall Applied N With Cover Crops, Corey Lacey
Improving The Efficiency Of Fall Applied N With Cover Crops, Corey Lacey
Theses and Dissertations
Nitrate loss studies in Midwestern tile-drained fields have found that fall applied nitrogen (N) resulted in elevated nitrate concentrations in tile water during both the corn and soybean year of a 2 year rotation. The effectiveness of cover crops to reduce nitrate leaching when N is spring applied has been well demonstrated, however there is a dearth of knowledge on the ability of cover crops to reduce nitrate leaching in a system where N is fall applied. Thus, the objectives of this research were to (i) investigate the efficacy of winter cover crops to reduce nitrate leaching from fall applied …
