Abstract
The study was conducted at Sam Higginbottom University of Agriculture Technology and Sciences’ Department of Soil Science and Agricultural Chemistry Lab. A total of 27 samples were collected from 3 blocks (Pusapatirega, Denkada and Bhogapuram), 9 villages, and analysed for physico-chemical properties using standard laboratory at varying depths (0-15, 15-30, and 30-45 cm). The soil colour ranged from yellowish red to yellowish brown (dry) and reddish brown to yellowish-brown (wet). It had a red sandy loam texture. Bulk density 1.402 (Mg m-3), Particle density 2.603(Mg m-3), Pore space 43.44(%), Water Holding Capacity 40.23(%), Specific gravity 2.42, pH 7.63 neutral, Electrical Conductivity 0.25 (dS m-1) non- saline, and Soil Organic Carbon 0.37(%). Available Nitrogen 269.88(kg ha-1) is low, Available Phosphorous and Available Potassium 17.34 and 191.09 (kg ha-1) are medium. Exchangeable Calcium 4.63 (cmol kg-1) and Exchangeable Magnesium 1.91 (cmol kg-1) medium to high. Farmers need to maintain a soil health card, adopt proper management techniques, and provide adequate nutrients to the soil in order to overcome pollution.
