Spatial and Temporal Soil Nitrogen Distribution After Shallow Disk Manure Injection in Corn

The purpose of this field research was to explore nitrogen (N) distribution in the form of nitrate and ammonium in both a spatial and temporal manner over two seasons in manure injection plots in central Pennsylvania. The description of N movement from high concentration at the manure band through the season can aid in understanding of nutrient migration and utilization efficiencies.

Recommendations for Manure Injection and Incorporation Technologies for Phase 6 Chesapeake Bay Watershed Model
