Description
Remineralization of immobilized 15N labelled urea N applied to rice crop at the rate of 180 kg N/ha was determined. Mineral N increased rapidly up to 14 days of incubation and thereafter remained more or less constant. The recovery of fertilizer as mineral N varied between 0.7 and 3.1 μg/g soil. The percent mineralization of labelled organic N ranged between 3.1 and 9.5. (author). 5 refs., 2 tabs., 1 fig
