Abstract The object of the present investigation was to study the fungal decomposition of organic matter from different sources, added to the saline soils. The organic matter added was in the form of fresh cuttings of two salt tolerant harbaceous plants namelyDiplachne fusca (Kallar grass) andSesbania aculeata (Dhancha). In addition to these treatments, farm yard manure and press mud (waste of sugar industry) were also used as a source of organic matter. Twelve combinations of these treatments were studied. A number of fungi were isolated from differently treated saline soils incubated at 30 °C. Among the fungi isolatedAspergillus spp. andFusarium solani had the highest frequency of occurrence. The relative cellulolytic ability of 10 fungal species was also estimated.Alternaria humicola andNigrospora sp. were found to be the most cellulolytic among the fungi isolated. The decrease in organic matter due to microbial decomposition was found to be most rapid during first two weeks of incubation. Among the treatments with one organic matter source, press mud produced maximum humus equal to 0.28 %. The pH and electrical conductivity increased slightly due to the closed system where no leaching took place.
