STUDIES ON CERTAIN ECOLOGICAL ASPECTS OF SOIL FUNGI. III

Certain ecological aspects of soil fungi from three different localities. viz., forest, cultivated field and grassland, quite near to each other, have been studied. The forest was chiefly dominated by Sal (Shorea robusta). Triticum vulgare, Pisum sativum and Brassica campestris (in winter), Pennisetum typhoides, Sorghum vulgare, Zea mays and different Phaseolus spp. (in rainy season) were grown in cultivated field whereas in grassland Cynodon dactylon was the dominated species. sample were collected from 8 different depths, viz., 0-2, 2-7, 7-12, 12-17, 17-25, 25-35, 35-45 and 45-60 cms separately in sterilized soil containers. The sampling of soil was continued for a year in 3 different seasons i.e. summer, rainy and winter of the year 1970. The fungal population was generally found to be highest in upper layer and with an increase in depth the fungi per gm dry soil decreased gradually. Amongst 3 localities, fungal population was highest in forest sample and lowest in the grassland in  all the corresponding depths. The maximum population in forest and cultivated localities was recorded during rainy season whereas in grassland it was in winter. The lowest population was always in the summer season. Organic matter content, moisture content, pH, depth of the sampling spot, locality and seasonal variation seem to play important role in distribution of mycoflora. Aspergilli were in majority through the investigation. (Full paper at Slideshare.net)
