1. Humic Products in Agriculture: Potential Benefits and Research ChallengesHumic products have been used in cropland agriculture for several decades, but lack of widespread credibility has restricted their use to small proportions of farmers. To improve the credibility of humic products, we propose future actions to close four knowledge gaps. First, while the capacity of humic products to improve plant growth has been proven in greenhouse and growth chambers, more such work is needed in field conditions, especially to determine the modifying effects on humic...

2. 4R Nitrogen Management Effects on Silage Corn ProductionThe 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 |
