Abstract
An experiment was conducted in 2022-23 with prime objective to assess the Physical and Chemical Properties of Soil at different depths of various sites of Thondamuthur, Anaimalai and Karamadai blocks of Coimbatore District, Tamil Nadu. The soil samples were collected at 0 -15, 15-30 and 30-45cm depth following standard procedures. The texture of soil samples was sandy loam. It clearly indicated that soil has good Water Holding Capacity (32.99 to 40.42%) with drainage where bulk density has shown significant range 1.04 Mg m-3 to 1.22Mg m-3 and Particle density ranges from 2.07 Mg m-3 to 2.50 Mg m-3. The pH of soil is neutral to alkaline in nature 7.372 to 8.285 which is suitable for all kinds of crops were electrical conductivity also shown (2.07 to 2.28 dSm-1 and was suitable for all crops. Organic carbon ranged from medium to high (0.586 to 1.209 %). These soils have optimum Nitrogen 284.9 kg ha-1 to 381.8 kg ha-1 in all blocks. Phosphorus 22.13 kg ha-1 to 26.15 kg ha-1 content is optimum in all samples. Potassium 112.58 kg ha-1 to 158.63 kg ha-1. Optimum in all locations. There is an including awareness of the need to pay greater attention in the role of organic matter enhancement for good soil health and proper nutrition of plant so as to attain optimum economic yield and soil is suitable for all major tropical and sub-tropical crops.
