| ABSTRACT The volatilization of ammonia (NH3) and nitrate leaching (NH3-) are the main processes of nitrogen (N) loss in the soil. The objective of the study was to evaluate N losses by NH3 volatilization and mineral N transformations in the soil with urea coated with poultry litter (urea + litter) compared with other sources of N, under two moisture conditions. The experiment was conducted in a controlled environment with a 5 x 2 factorial arrangement with four replicates, five N sources (urea, SuperN®, Kimcoat®, urea + litter and control without fertilizer) and two moisture contents [80 and 100% of field capacity (FC)]. The total volatilized NH3 did not differ between the sources, regardless of the soil moisture condition, ranging from 10.8 to 13.2% of... |
