Impact of legacy soil phosphorus on losses in drainage and overland flow from grazed grassland soils.

Abstract

Rates and quantities of legacy soil phosphorus (P) lost from agricultural soils, and the timescales for positive change to water quality, remain unclear. From 2000 to 2004 five 0.2ha grazed grassland plots located on a drumlin hillslope in Northern Ireland, received chemical fertiliser applications of 0, 10, 20, 40, 80kgPha-1yr-1 resulting in soil Olsen P… (More)
