A study was conducted at College of Agriculture, Padannakkad to know the status of various biological properties of Pokkali tracts. The parameters analysed were organic matter content, microbial biomass carbon, dehydrogenase activity and microbial population comprising of bacteria, fungi and actinomycets. Thirty soil samples were collected from different locations and analysed for the above said parameters using standard procedures. The results revealed that the soil is rich in organic matter, which ranged from 2.04 to 3.57 per cent. Microbial biomass carbon in the sample varied from 125.2 to 260.3 µg TPF g-1 soil with a mean value of 201.5 µg TPF g-1 soil. The dehydrogenase activity in the soil was found to be between 1985.48 µg g-1 soil to 2300 µg g-1, which is comparatively higher than non-flooded soil, emphasizing that flooded condition favours dehydrogenase activity. Bacterial, fungal and actinomycetes population was 4.3 x 107, 2.3 x 104 and 3.2 x 104 respectively. The presence study indicated that flooded rice soil is one of the best sources to study microbial diversity. However detailed investigation is required to assess impact of microbial community on various soil parameters.
