Status of Correlation between status of pH, Organic Carbon and available Iron (Fe) in black soil of Navagarh block under Janjgir District in Chhattisgarh

The study was carried out to soil fertility on the basis of correlation between status of OC, pH and available Fe in black soil of Navagarh block under Janjgir district of Chhattisgarh. The soil pH varied from 5.8 to 8.0 (mean 6.24) and indicated that soils were found to be moderately acidic to slightly alkaline in reaction. The mean value of organic carbon was 0.58% and about 90% soils of this block comes under medium fertility group. The available iron and manganese and content were ranged from 0.44 to 91.6 mg kg⁻¹ (mean 23.8 mg kg⁻¹) respectively in soil of Navagarh block. Most of soil samples were found in sufficient levels of Fe. The correlation studies between available micronutrient Fe and soil properties (pH, OC) showed significant correlation with pH but significant with OC.
