AbstractThe present work aims at assessing the releasing of N mineral in the forms of NH 4 + e NO 3 -in a due time after the beginning of the flooding in different lowland soils of RS and correlate the forms of N mineral to the soil characteristics. Samples of 15 lowland soils of RS were collected in 13 cities of flooded rice producing regions. The samples were put into leaching tubes and incubated for 24 weeks. During this period, leaching was carried out and the N-mineral content was determined. The N… Show more
