Assessment of Physico-chemical Properties of Soil from Different Blocks of Purnea District, Bihar, India

The present study was carried out in the Soil Science and Agricultural Chemistry lab at Sam Higginbottom University of Agriculture Technology Sciences. sampling location Purnea district Bihar. objective to analyze Physico-chemical properties soil Bihar, India. Depth wise samples were collected from nine different village 3 blocks selected spots 0-15, 15-30 30-45 cm. total no. 27 several farmer's fields, composite out. results revealed that texture is sandy loam. bulk density ranged 0.95 1.29 (Avg. 1.12) Mg m-3, particle 2.22 2.34 2.28) pore space 43.19 48.71 45.95) %, water holding capacity 38.56 46.58 42.57) %. pH 6.52 6.82 6.68), E.C. 0.31 0.45 0.38) dS m-1. organic carbon 0.15 0.33 0.24) Available nitrogen 162.02 255.64 208.83) kg ha-1, available phosphorous 8.84 20.21 14.525) potassium 76.30 170.70 123.50) exchangeable calcium 3.2 4.8 4.00) Meq 100g-1, magnesium 0.60 1.00 0.855) 100g-1. has acceptable BD, PD, space, capacity. As a result beneficial electrical conductivity for plants, slightly acidic neutral. Nitrogen, Phosphorus, Potassium, Exchangeable Calcium Magnesium are low macronutrients. indicated overall soils moderate conditions farmers required maintaining health card, adopting suitable management practices, providing proper nutrition overcome pollution effect.
