Soil is a complex mixture of minerals, organic matter, liquids, gases and microorganisms that all works together to support life. Soil fertility is one of the important factor that determines yield of the crops. The present study focuses on analysis of physico - chemical properties of soils that were collected from five districts of Cauvery delta zone of Tamil Nadu, India. The physical and chemical parameters of soil samples such as pH, Electrical conductivity, Organic carbon and nutrient status of available Nitrogen, Phosphorus and Potassium were analyzed. The soil samples comprising four different textural types viz., Clay soil, Clay loam, Loamy soil and Sandy clay loam from ten different locations were noticed. Soil pH of the collected samples was alkaline and neutral, ranging from 7.0 to 8.10 and soil EC ranged from 0.14 to 1.20 dSm-1. The available Nitrogen content of the collected soil samples ranged from 125 to 295.05 kg ha-1. The available Phosphorus content of the collected soil sample ranged from 7.86 to 37.50 kg ha-1 and the available Potassium content of the collected soil sample ranged from 232 to 390 kg ha-1. This knowledge on soil nutrient status could help the researchers, farmers and planners for a better crop production.

Key words : Cauvery delta zone, physico - chemical properties and Available soil nutrients NPK.
