An Inventory of Mitigation Methods and Guide to their Effects on Diffuse Water Pollution, Greenhouse Gas Emissions and Ammonia Emissions from Agriculture

Type: article
Abstract: Effectiveness: N: Conversion to ungrazed grassland would reduce NO 3 losses by around 90%; annual losses on converted land would typically be <5 kg N/ha.Ammonium and nitrite losses to water would also be reduced.Similarly, direct and indirect N 2 O and NH 3 emissions would be reduced by around 90%. P and sediment: Particulate P and associated sediment losses in surface runoff would be reduced by around 50%.Soluble P losses would be reduced in the longer-term.Other pollutants: There would be reductions in energy use and increased carbon storage in the grassland soils; initially in the range 1.9 to 7.0 tCO 2 e/ha/year.However, it is unlikely that these increases would be sustained over the longer-term (>50 years), as a new soil carbon equilibrium level would be reached.
