1. 4R Nitrogen Management Effects on Silage Corn Production

The 4R nutrient stewardship framework aims to improve fertilizer management through four core principles: right source, rate, time, and place. Nitrogen is one of the most important and costly inputs for silage corn production. Excessive or inefficient N applications rapidly decrease profits for growers and can cause environmental concerns. Nitrogen loss can occur through leaching, runoff, and denitrification. Most previous studies evaluating N management for silage corn have only examined one... B. Okorie, M. Yost, K. Deep, N. Howard
