Summary
In preliminary work in the enzymatic activity of a semi-arid Gezira soil microbes were counted and urease, dehydrogenase, and Catelase activities were measured in five soil horizons from 0 to 72 inches depth. Urease and dehydrogenase activities of unamended soil from all horizons appeared to be better indicators of biological status than catalase activity. Biological activity was marked in the top soil (0–2 inches) — the zone of grass root activity — but decreased gradually to reach a low level in deeper horizons.
