Abstract
Abstract Loss of NH3 from urea fertilizer in a cultivated sandy desert soil was evaluated by using various fertilizer treatment regimes. The nitrification of added urea increased with the pretreatment of (NH4)2SO4. The increase in nitrification rate was directly related to the amount of (NH4)2SO4 added. These results suggested that when urea was applied after sufficient increase in nitrification rate, i.e., 3 to 5 weeks after the pretreatment with NR+ 4 fertilizers, the NH+ 4 produced by the hydrolysis of urea was quickly nitrified, leaving low concentration of NH+ 4 in soil and resulting in decreased losses of NH3. Among the different NH+ 4 containing or forming fertilizers, (NH4)2SO4 was significantly better in arresting NH3 loss from a subsequent application of urea. The decreased loss of N was reflected in higher yields of pearl millet.
