Current status of major nutrients (Av. N, P and K) deficiencies in soils of Koriya district of Chhattisgarh

Author(s): Awanish Kumar, LK Srivastava, Rakesh Banvasi and VN Mishra
Abstract: Crop productivity and human health are widely associated with soil health. Sustaining the nature and degree of nutritional deficiency problems is proper in improving the fertilizer recommendations by addition of major nutrients in the fertilization schedule. In order to understand the variation in macronutrient deficiencies in the district, we carried out macronutrient deficiencies delineation studies in soils of Koriya district of Chhattisgarh. The district consists of five taluka viz. Bharatpur, Manendragarh, Baikunthpur, Khadgawa and Sonhat and 57 villages were selected randomly. Total 342 surface soil samples (6 samples each village) were collected using global positioning system (GPS). Results revealed that the soils of the Koriya district (over all mean value of all taluka) were mainly deficient in available nitrogen (Av. N) (93.0%), followed by phosphorous (Av. P) (76.0%) and potassium (Av. K) (16.0%) out of 342 surface soils (0-15 cm) samples. The nutrient index value for Av. N and P was ranged from 1.02 to 1.10 and 1.04 to 1.32 with mean value of 1.07 and 1.24 respectively. Over all fertility rating for Av. N and P of all taluka is rated under very low category. Deficiency of Av. N and Av. P was most serious in the soils of Koriya district. Deficiencies of Av. K were almost negligible and are not currently affecting any major threats to the crop production. This study indicates that for sustaining soil and crop productivity, and good quality of harvest, balance fertilization and scheduling essentials to be improved with addition of the major nutrients scarce in Koriya district of Chhattisgarh.
