Abstract
Fertilizer use efficiency can be increased by minimizing the loss of N by ammonia volatilization. There have been efforts in developing slow release fertilizers which release nutrients at rates and concentration that allow plants to maintain maximum growth but minimize N losses. This study was conducted to evaluate the effect of urea coated with different concentrations of NHA on NH3 volatilization lost. Bungor Soil Series Typic Kandiudults was used in this study. Urea coated with four different concentrations of nitrohumic acid NHA and non-coated urea were compared. Urea coated with different concentrations of NHA did not show any significant different in reducing total NH3 lost. when compared to non-coated urea except for 8 NHA coated urea. There was significant accumulation of nitrate in the soil for urea coated with NHA compared to non-coated urea. Thus urea fertilizer efficiency could be increased when the urea was coated with nitrohumic acid.
