Nitrogen,phosphorus and potassium utilization and their nutrient cycling in a beef‐forage production system

摘要：

Quantification of nutrient flow is the first step for nutrient management in the livestock production system.The objective of this study was to quantify the cycling for nitrogen ( N), phosphorus ( P) and potassium ( K) in a beef‐forage production system in Japan.
