Study of the Different Forms of Soil Potassium in Ujjain Tehsil of Ujjain District of Madhya Pradesh, India

The current research was carried out in the Ujjain tehsil (Ujjain) district of Madhya Pradesh state, India, with the aim of estimation the different forms of soil potassium and different characteristics of the Soil. Throughout the research region, 150 surface soil samples with a depth of 0 to 15 cm were collected. Collected soil samples were analyzed for physico-chemical properties namely texture, pH, Electrical conductivity, organic carbon and different forms of potassium (K) i.e. Water Soluble Potassium, Exchangeable Potassium, Available Potassium, Non-exchangeable Potassium, Lattice Potassium and Total Potassium. To observe that the soil texture of Ujjain district is varied from silty clay to clay, soil pH ranged from 7.01 to 8.15, electrical conductivity was varied from 0.10 dSm-1 to 0.79 dSm-1, organic carbon is varied between 0.30 to 0.60 % and The research region's ranges for different forms of potassium i.e. Water Soluble Potassium, Exchangeable Potassium, Available Potassium, Non-exchangeable Potassium, Lattice Potassium and total K were 3.10-24.00 mgkg-1, 118.38-196.12 mgkg-1,129.95-206.70 mgkg-1,200.0-410.0 mgkg-1 ,7943.75-17515.71 mgkg-1 and 8500-18000.0 mgkg-1, in that order. The mean value of Water Soluble Potassium, Exchangeable Potassium, Available Potassium, Non-exchangeable Potassium, Lattice Potassium and Total Potassium was 11.47 mg kg-1, 148.67 mg kg-1, 160.11 mg kg-1, 330.16 mg kg-1, 12478.11 mg kg-1 and 12968.96 mg kg-1, respectively.
