Abstract
Powderd plant tops of diplachne
fusca and sesbania aculeate were mixed with soil and incubatd at 27-
300 C for 90 days to study the effects
of different salinity levels on C and N mineralization, humus formation , humification productivity and soil microflora. The results indicate that increasing salinity depressed the
rate of carbon mineralization and its transformation into stable organic matter. Similarly the fungal and bacterial population was also suppressed . however, ammonia volatilization increased with the increase in salinity resulting in greater nitrogen losseswhich were more in case of Saculeata amendment than D.fusca.
