Soil microorganisms such as bacteria and fungi play an important role in soil fertility and promoting the plant growth. Sixty soil samples are collected of different agricultural crop fields such as groundnut field, sugarcane field, Plantain field, turmeric field, tapioca field and wasteland with Parthenium field in and around Thiruvannamalai, Tamil Nadu were investigated soil moisture content by oven drying method and diversity of fungi by using serial dilution plating method with standard Potato Dextrose Agar (PDA) for qualitative and quantitative pattern. The moisture content of different soil samples collected from the above fields were found from 11.0% to 26.3%. Among the soil samples, the groundnut and turmeric field show higher moisture as 26.0% and 26.3% and the lowest level was observed in sugarcane and tapioca soil with 11.0% and 17.0% respectively. For analysis of fungi, 22 species were enumerated from the above soil samples in which Aspergillus niger, A. flavus, A. terreus, A. fumigatus, Trichoderma spp., Cladosporium cladosporioides, Curvularia lunata, Gliocladium sp., Fusarium sp. and white non sporulating fungus were remarkably present. Regarding the distribution of occurrence, Plantain filed show highest as 28% followed by groundnut field with 23%, Sugarcane field 17%, Tapioca and waste land soil each with 14% and the turmeric field soil has the lowest occurrence as 4% of fungal population. It is concluded that from the present study as the turmeric field soil has an antimicrobial effect which shows very low population of fungi in their soil environment when compared with other soil samples.
