Abstract:
An experiment was conducted during 2018-19 and 2019-20 at Korea district under northern hills region of Chhattisgarh to evaluate soil chemical and biological properties of Rice-wheat cropping system in Alfisol. The data indicated that, the studied soils are classified under sandy clay loam (SCL) texture, which is slightly good for plant growth and development. The Soil bulk density, particle density and porosity values ranged from 1.35 to 1.48 (mean 1.43) Mg m⁻³, from 2.60 to 2.69 (mean 2.64) Mg m⁻³and from 43.46 to 48.28 (mean 45.75) percent, respectively. Among the rice-wheat cropping systems, Soil pH, EC and OC ranged from 6.32 to 7.18 (mean 6.88), from 0.04 to 0.24 (mean 0.15) dS m^-1 and from 3.89 to 4.96 (mean 4.20) g kg^-1 respectively. The pH of soils is slightly acidic in nature, as the Alfisols was derived from acidic parent materials. These soils had medium to high microbial bio-mass carbon, MBN, and dehydrogenase acid and alkaline phosphatase activity.
