Summary
Application of neem products like neem leaf and neem cake to wetland soil did not have any adverse effect on the population of heterotrophic microflora; nitrifying bacteria, on the other hand, decreased significantly due to addition of neem cake and fresh and dried neem leaf with urea. It is suggested that neem leaf could be used as an inhibitor of nitrification for enhancing nitrogen use efficiency of fertilizers where neem leaf is available in plentiful supply.
