Two manure management and storage methods, manure stockpiled anaerobically or composted aerobically for 104 days were evaluated. Nitrogen recovery was 85.7% and 56.4% for stockpiled and composted manure, respectively. Organic nitrogen concentrations were greater for composted manure while ammonium nitrogen concentrations were greater for stockpiled manure. Simulation of hot, dry conditions during field application indicated the amount of ammonia nitrogen lost from stock¬piled manure was not great enough to offset the total nitrogen recovery advantage of this method. When evaluated on a nutrient basis, stockpiled manure has greater value as a fertilizer compared with composted manure in this study.
