Comparison of the fertilizing value of urea and ammonium nitrate applied before sowing and as a topdressing



Comparison of the fertilizing value of urea and ammonium nitrate applied before sowing and as a topdressing



Roczn. Nauk rol, 89A: 195-211



In pot experiments with oats and rape grown on acid soil (pH 5) and on soil limed to pH 6.7, urea became hydrolysed during the first week after application, but nitrification especially in the acid soil was significantly slower; the NO3 contents of unfertilized acid soil and soil given urea or NH4NOsbecame equalized only in the third week. Losses of N from surface-applied urea were 5-8%, ten times higher than those from NH4NO3.
