| An intact lysimeters study was carried out to measure the potential nitrogen (N) losses on an andisoil of Southern Chile with different fertilisers. The treatments tested were: fish slurry (FS), dairy slurry (DS), potassium nitrate (IF) and a control treatment (C), with no N addition. An equivalent amount of 150 kg of total N ha-1 was applied to each lysimeter and then the equivalent to 1260 mm of rainfall was irrigated over a 90 days period. Leachate samples were analysed for nitrate, nitrite, ammonia and organic N (No). Total N losses were calculated as the product between drainage and the respective N concentration in the leachates. Lowest N losses were obtained in the control and FS treatments (66 kg N ha-1) and the greatest amount was obtained in the... |
