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

The present study was completed activity in the Soil Science and Agricultural Chemistry lab at Sam Higginbottom University of Agriculture Technology and Sciences. The savoring location was Purnea locality of Bihar. The objective of the study was to resolve the Physico-synthetic properties in soil of Purnea locality of Bihar, India. Depth wise soil samples were composed from nine different suburb of 3 blocks of selected spots at 0-15, 15-30 and 30-45 cm. The total no. of 27 samples were calm from several grower's fields, and composite inspecting was carried out. The results told that the texture of the soil is arenicolous loam. The largeness density categorized from 0.95 to 1.29 (Avg. 1.12) Mg m-3, particle bulk from 2.22 to 2.34 (Avg. 2.28) Mg m-3, pore space from 43.19 to 48.71 (Avg. 45.95) %, water ownership competency from 38.56 to 46.58 (Avg. 42.57) %. The pH ranged from 6.52 to 6.82 (Avg. 6.68), E.C. categorized from 0.31 to 0.45 (Avg. 0.38) dS m-1. The soil organic element ranged from 0.15 to 0.33 (Avg. 0.24) %. Available nitrogen categorized from 162.02 to 255.64 (Avg. 208.83) kg ha-1, available phosphorous categorized from 8.84 to 20.21 (Avg. 14.525) kg ha-1, available potassium categorized from 76.30 to 170.70 (Avg. 123.50) kg ha-1, interchangeable calcium ranged from 3.2 to 4.8 (Avg. 4.00) Meq 100g-1, interchangeable magnesium ranged from 0.60 to 1.00 (Avg. 0.855) Meq 100g-1. The Soil has satisfactory BD, PD, pore space, and water possession capacity. As a result of the advantageous electrical generated power for plants, the pH of the soil is slightly sour to noncommittal. Available Nitrogen, Phosphorus, Potassium, Exchangeable Calcium and Magnesium are low in macronutrients. The results pointed out that overall soils were in moderate conditions and producers required claiming soil health label, adopting suitable administration practices, and providing correct nutrition to the soil to overcome the dirtiness effect.
