The rate of conversion of urea to ammonium was studied in some acid tea soils of Sri Lanka. The stable levels of urease present in these soils are adequate to hydrolyse the applied urea. There was rapid and almost complete conversion of urea to ammonium and the rate of hydrolysis was independent of soil moisture at 25 per cent and above. The rate of conversion of urea to ammonium depended on the soil polyphenol concentration and had no relationship with either the organic carbon content or the… CONTINUE READING
