Takao, a rice farmer in Japan has created an innovative
and also very effective way of production based on symbiosis on between varied
species of animals and plants in his rice paddies: the ducks feeds on insects
and weeds and their droppings enrich the soil, promoting the development of plankton,
which feed the fish. Also the aquatic plant called azolla supplies nitrogen for
the plant's growth. The environment can provide their own maintenance and
protection, without any chemicals. An innovative and also profitable review of
production's methods.
