Phosphorus exchangeability and leaching losses from two grassland soils
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2002)
Although phosphate phosphorus (P) is strongly sorbed in many soils, it may be quickly transported through the soil by preferential flow. Under flood irrigation, preferential flow is especially pronounced and associated ...
Seasonal fluctuations in phosphorus loss by leaching from a grassland soil
(Soil Science Society of America, 2004)
Phosphorus losses from soils have been reported to impair the water quality, resulting in deaths of fish and other marine animals, and can harm human health. The objective of this study was to determine the seasonal ...
Improved nitrogen management with eco-n nitrification inhibitor : an example of "growing for good"
(New Zealand Large Herds Association, 2005-04)
The recent report by the New Zealand Parliamentary Commissioner for the Environment, called "Growing for Good", highlighted the adverse impacts that nitrate leaching can have on water quality. It called for a 'redesigning ...
