Dissolved organic nitrogen : an overlooked pathway of nitrogen loss from agricultural systems?
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2009)
Conventional wisdom postulates that leaching losses of N from agriculture systems are dominated by NO₃⁻. Although the export of dissolved organic nitrogen (DON) into the groundwater has been recognized for more than 100 ...
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 ...
