Assessment of physico-chemical properties of soil from different blocks of Katihar district, Bihar

Abstract

The present research topic entitled Assessment of Physical Properties of Soil from Different Blocks of Katihar District, Bihar was carried out at the Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj. Department of Soil Science and Agricultural Chemistry formerly called Naini Agricultural Institute, (U.P.). During the year 2023-2024. The soil samples were collected at three depths: 0-15 cm, 15-30 cm, and 30-45 cm, from nine different villages of three different blocks of Katihar areas, a total of 27 samples collected and analyzed for their physical parameter by using standard Laboratory Technique. The result showed that the Soil Texture of Pranpur, Azamnagar, and Sameli block is Sandy loam. The Bulk Density reported 1.00 -1.42 Mg m-3, Particle Density reported 2.20 to 2.56 Mg m-3, Percent of Pore Space varied 41.08 to 54.08%, Water Retaining Capacity ranged 39.38 to 51.89%. Results suggest that farmers should adopt appropriate soil management techniques, such as crop rotation and conservation tillage, which will contribute to maintain the soil physical characteristics to ensure the sustainability of agricultural practices and the long-term health of the soil.
