The process by which nitrogen moves throughout the soil varies based on factors such as cover crop usage, landscape position, and crop rotation. The purpose of this research is to reduce uncertainties that are associated with Missouri’s nitrogen fertilizer recommendations and highlight the role underlying soil health plays in management strategies. In this study, six rates of nitrogen fertilizer from 0-210 lb/ac were applied across four field sites throughout the central region of Missouri. The objective of this study was to evaluate the effect of inherent soil health, landscape position, and cover crops on nitrogen use efficiency. |
