This study will determine the impact of tillage regime on fertilizer uptake efficiency and has the potential to improve upon the standingrecommendation system, benefiting corn producers by maintaining yields while reducing fertilizer input costs.
Objectives
Determine the impact of long-term conventional- and zero-tillage management on fertilizer 15N uptake efficiency in corn
Assess the fate of residual 15N-fertilizer in inorganic and organic N pools post-harvest for zero- and conventional-till.
Quantify the contribution of residual fertilizer N to the following crop for zero- and conventional till.
