Abstract:

The widely adopted Alternate Wetting and Drying (AWD) irrigation for rice production is increasingly needed to investigate for assessing nitrogen fate in the soil. An experiment was conducted under aerobic soil conditions to study Nitrogen (N) transformations. The simple numerical analytical model used to simulate urea, ammonical nitrogen (NH4-N) and nitrate nitrogen (NO3-N) concentration in experimental plot. Simulation of urea concentration decreased as 2 %, ammonical nitrogen and nitrate nitrogen concentration increased as 9 % and 9.8 % compared to observation. The results reflect the urea concentration is high in 37.5 cm soil depth, ammonical nitrogen and nitrate nitrogen concentration is high in 7.5 cm soil depth.


Keywords: Nitrogen, Ammonium, Nitrate, Alternate wetting and Drying
