Abstract

The study was carried out to evaluate the soil fertility with respect to available calcium status in red and yellow soils of Sakti block in Janjgir-Champa district of Chhattisgarh. Grid based surface (0-15 cm depth) soil samples were collected using global positioning system (GPS) from 130 villages of Sakti block consisting of red and yellow soils. The soil samples were analyzed for calcium. The soils were high in available calcium content. The status of available calcium varied from 224 to 8960 kg ha^-1 with a mean value of 5037 kg ha^-1. 97.31 per cent and 2.68 per cent soil samples from the study area were classified as high and low fertility class, respectively.

Abstract

The study was carried out for evaluation of soil fertility with respect to available sulphur status and its relationship with important physico-chemical characteristics in red and yellow soil of Dabhra block under Janjgir district of Chhattisgarh during 2013-14. Grid based surface (0-15 cm depth) soil samples were collected using global positioning system (GPS) from 126 villages from every 10 ha land area. The soil result revealed that pH varied from 4.1 - 8.4 (mean 5.7) and indicated that soils were found to be acidic to slightly alkaline in reaction. The electrical conductivity (EC) varied from 0.01 to 0.97dS m-1 with a mean value of 0.16 dS m^-1 at 25°C of the Dabhra block. The total salt content of these soils, expressed as EC, were categorized as <0.1, 0.1 to 0.2, 0.2 to 0.3 and >0.3 dSm^-1. The soil ranged from 0.01-1.3 with a mean value of organic carbon 0.57 per cent, about 52.66 per cent soil of this block came under medium, 31.75 per cent sample under low and only 14.29 per cent sample had high range of fertility group. The soil was high in available S content. It ranged from 7.28 to 89.6 kg ha^-1 with an average of 35.02 kg ha^-1. The available S in more than 44.37 per cent soil sample was classified as high, 21.89 per cent sample under medium and 33.72 per cent sample in low fertility class under fertility group. The correlation between available S and soil properties showed negative significant correlation with pH and positive significant correlation with OC.
