The farmgate phosphorus balance as a measure to achieve river and lake water quality targets

This short communication proposes a pathway for achieving river and lake water quality phosphorus (P) targets using the agricultural farmgate P balance (FPB). The context is the internationally important Lough Neagh and general river network in Northern Ireland (NI). A meta-analysis shows a direct a...

Description
Summary:This short communication proposes a pathway for achieving river and lake water quality phosphorus (P) targets using the agricultural farmgate P balance (FPB). The context is the internationally important Lough Neagh and general river network in Northern Ireland (NI). A meta-analysis shows a direct and strong linear relationship between the FPB and, with a one-year lag, the mean soluble reactive phosphorus (SRP) concentration for ninety-three river sites over eighteen years (R2 = 0.73, p
