Ammonia loss reduction, exchangeable ammonium and available nitrate retention in soil treated with urea mixed with humic acid and acid sulphate soil.
Exchangeable ammonium (NH4 + ) could be recovered in soil by the application of humic acid (HA) and acid sulphate soil. The ability of humic acids to retain NH4 + has been demonstrated in our previous study. In that study, the effect of both acids on soil exchangeable NH4 + , dry matter p...
