Cauvery Delta Zone

The Cauvery Delta Zone in Tamil Nadu is an agriculturally rich region that spans several districts in the southeastern part of the state. The Cauvery Delta Zone encompasses districts like Thanjavur, Tiruvarur, and Nagapattinam, and Myladuthurai. It is located along the eastern coast of Tamil Nadu. This zone is characterized by its fertile alluvial soil, abundant water resources from the Cauvery River, and a tropical climate. The region experiences a tropical climate with a significant monsoon season, ensuring reliable water availability for agriculture. The Cauvery Delta is known for its fertile alluvial soil, which is rich in nutrients and ideal for various crops. This soil type is the result of sediment deposition by the Cauvery River over centuries. The Cauvery Delta is often referred to as the "Rice Bowl" of Tamil Nadu due to its extensive cultivation of paddy rice.
