Peculiar way of rice farming in kaipad

Rice farming is carried out in a peculiar way in Kaipad, purely in a natural way relying on the monsoon and the sea tides. Single-crop of rice is cultivated, on mounds, in a low to medium saline phase of production cycle during June to October. Harvesting takes place by the end of October. Harvested products are brought in yachts from the interior parts of Kaipad rice tracts. This is followed by  traditional fishing, during the high saline phase, during November to April. Neither chemical fertilizers nor plant protection chemicals are used in rice, fish, or shrimp farming. The tidal flows make the fields highly fertile through a symbiotic relationship between rice crop and prawn, shrimp, fish etc. The fingerlings  of fish, shrimp, prawn etc. which swim in from the sea and the backwaters after the rice harvest, feed on the leftovers of the harvested crop. The rice crop draws nutrients from the excrement and other remnants of these sea creatures. Also, there is no purposeful removal of weeds as practiced in modern rice farming system.
