Technical Abstract: Nutrient cycling in forage production systems is complicated and crucial; complicated, because elements can exist in many forms and are affected by both biological and physical processes, and crucial, because nutrients affect productivity, profitability, and environmental sustainability of forage systems. We discuss the pools that nitrogen and phosphorus inhabit in forage production systems, the pathways they take as they cycle through the soil, plants, and herbivores, and the ways they are lost to the environment. This chapter provides a concise summary of nitrogen and phosphorus cycles that will benefit students and practitioners, including farmers and farm advisors.
