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 Jhunjhunu district, Rajasthan, 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 color varied from dark brown to very dark brown, light brownish grey to yellowish brown and light yellowish brown to Dark greyish brown. The soil color (wet condition) varied from very dark greyish brown to Dark yellowish brown, yellowish brown to brownish yellow and dark brown. Bulk and Particle densities of these soils varied from 1.04 to 1.29 Mg m-3 and 1.60 to 2.46 Mg m-3. The pore space (%) varied from 30.22 to 54.50%. The water holding capacity (%) varied from 37.49 to 64.66%. The texture was dominantly sandy loam. Soil pH varied from 7.02 to 9.22. The Electrical Conductivity ranged from 0.21 to 0.39 dS m-1 and the maximum value was recorded in Ajeetpura village. The value of total Organic Carbon (%) was varied from 0.31 to 0.80%. The Available nitrogen content in the soil was varied from 150 to 277 kg ha-1 and nitrogen content was found low in all the entire’s farmer’s field. The Available Phosphorus content was found in between 15.20 to 26.35 kg ha-1. The Available Potassium content in the soil was varied from 109 to 245 kg ha-1 and the potassium was found medium on the surface horizon and decreased with increased in soil depths. The Exchangeable Calcium content in the soil varied from 2.45 to 5.70 cmol (p+) kg-1 and was found in the sufficient amount. The Exchangeable Magnesium content was varied from 2.25 to 3.70 cmol (p+) kg-1. The amount of Sulphur content in the varied from 21 to 29 kg ha-1 and was found to be in deficient amount. 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.
