Phosphorus use efficiency in agricultural systems: A comprehensive assessment through the review of national scale substance flow analyses

This paper redefined the agricultural production system and its subsystems with respect to phosphorus (P) flow to improve the assessment of the phosphorus use efficiency (PUE), which is a key indicator for P security and sustainability of water resources. It also assessed the key P inflows, outflows...
