Leaching of nitrate and other nutrients from a grazed pasture
The object of this study was to determine the amounts of nitrate (NO 3 - ) and other nutrients leached from an intensively grazed pasture over 1 year. Concentrations of NH 4 + , NO 3 - , Ca 2+ , Mg 2+ , Na + , K + , SO 4 2- , PO 4 3- , and Cl - were measured in samples of water percolating through s...

The amount of element leached was calculated as the product of measured concentration and estimated drainage volume. Leaching losses over 1 year (kg/ha nil-N treatment; kg/ha +N treatment) were thus estimated as N (88; 193); Ca (154; 216); Mg (32; 44); Na (71; 86); and K (14; 21). Rainfall and estimated drainage were 1840 and 985 mm respectively. |
