Abstract
Twenty samples each of nornal and satine soils were taken. Their physico-chemical properties, total bacterial count and enzyme activity was determined. The enzymes studied were cellulase, invertase and dehydrogenase. lt was foun that higher concentrations of soluble salts decreased nitrogen and carbon contents, Enzyme activity decreased gradually with increasing salinity and at Ee level of 38.01 mmbojcm all the cnzymssemployed in this study were inactive. Bacterial counts also showed a declining trend with inc- rease in salinity. The decline ineazyms activity and bacterial count ; aposared to be associated with a ciange in osmotic potential of the | soil water phase, specific ion toxicities and a salting out effect of soluble saits on enzyme proteia.
