This study aims to assess the effects of animal supplementation and legume pastures on nitrogen balance in integrated crop-livestock systems.
Conducted in two phases, livestock and cropping, with three treatments: control pasture, legume mixture, and supplementation treatment.
Each treatment was replicated three times, with soybeans planted during the cropping phase.
Supplements increased stocking rate by 21% and legume treatments resulted in a 30% increase in residual nitrogen via feces and urine.
Supplementation increased residual nitrogen returned by 30% without impacting soybean yield (~4.1 Mg ha−1).
Nitrogen off-take by soybean was ~9% higher in supplemented and legume treatments compared to controls, while cattle carcasses showed no change.
Soybeans accounted for 96-97% of total nitrogen export, demonstrating the effectiveness of integrated nutrient management.
