Rice is the principal crop of the Chhattisgarh State. It covers 66% of all cultivable land and is mostly grown within the kharif cropping season. To increase sustained productivity without decreasing soil quality, algal bio fertilizers are widely used in the State. Hence, the culture of cyanobacterial bio fertilizers has been started on a regional basis. This includes survey, isolation and screening of stress-tolerant cyanobacteria. Thus, this study concerns the characterization of physical and chemical properties of soil collected from Mahasamund districts of Chhattisgarh state with respect to the biodiversity of cyanobacteria.
