Abstract:
An experiment was conducted in Department of Soil Science and Agricultural Chemistry, Naini Agricultural Institute, SHUATS, Prayagraj during 2020-21 to assess the physico-chemical properties of Soil in different blocks of Kanpur Dehat district, U.P., India. Depth wise soil samples were collected from nine villages at 0-15, 15-30 and 30-45 cm. Total 27 samples were selected for analysis. The results revealed that soil colour varied from grey colour to olive yellow in dry condition while from greyish brown to yellow brown in wet condition. The texture was dominantly sandy loam. The bulk density ranged from1.05 to 1.33 (Mg m-3), particle density from2.35 to 2.66 (Mg m-3), pore space from 42.52 to 55.19 (%), water holding capacity from 55.12 to 73.09 (%), specific gravity from 2.01 to 2.40. The pH ranged from 7.17 to 8.84, Electrical conductivity ranged from 0.15 to 0.51(dS m-1). The soil organic carbon ranged from 0.58 to 1.30 (%). Available nitrogen ranged from 142.16 to 440.52 (kg ha-1), available phosphorous ranged from 20.67 to 47.64 (kg ha-1) and available potassium ranged from 62.88 to 109.32 (kg ha-1), all of which showed decrease in value with increase in depth. Exchangeable calcium ranged from 0.7 to 2.57 (cmol (p+) kg-1), exchangeable magnesium ranged from 0.20 to 0.82 (cmol (p+) kg-1) and available sulphur ranged from 20.02 to 42.52 (kg ha-1) all of which varied significantly with site and depth. The results indicated that soils are good for cultivation of various crops. Farmers are required to maintain Soil Health Card which helps them to adopt suitable management practices and provide proper nutrition to soil.
