 Effects of amending urea with pyrite (Py) or potassium chloride (KCl) alone and in combination with copper sulphate (CuSO4) on NH3 volatilization and N-use efficiency in an Alfisol were evaluated. NH3 volatilization from surface-applied urea fertilizers was measured using a closed dynamic air flow system. Kinetics of NH3 volatilization over a 10-day period showed that the peak rate of NH3 loss was on day 3 with the unamended urea, whilst it occurred on day 4 with all amended urea fertilizers… CONTINUE READING
