The objective of the present study was to test some chelating compounds for their ability to retard urea hydrolysis in soils by inhibiting urease activity. The rationale behind evaluation of chelating compounds for inhibiting soil urease activity was that the chelating compounds are known to interfere with the functioning of enzymes involving sulphahydral (-SH) group like urease by chelating the functions having -SH groups. Also there are evidences to show that the chelating compounds have the ability to chelate with the metallic ions in enzymatic activities responsible for functioning of nitrifiers, mainly Nitrosomonas.* The effects of chelating compounds on soil urease have not been investigated and thus prompted evaluation of some chelating compounds for the purpose.
