rice has been used for a long time in Korea,
China, and Japan. It is one of the most popular
environmentally-friendly methods of agriculture that preserves the nature, produces
safe foods, protects public health, and increasing farm income.
Ducklings are highly resistant to disease or epidemics compared to other
animals and feed on underwater organisms and weeds that grow in swamps, farms,
and ponds. Their discharges work as
organic fertilizers that improve quality of soil. Ducklings are not trained, but their natural
habits are used in farming.
As ducklings pick and eat weeds and various harmful insects, no chemical
herbicides and pesticides are needed.
Also, their discharges reduce the use of chemical fertilizers by 1/3.
No use of chemicals saves cost of farming and produces safe and completely
quality rice for higher income of farm households. (duckling rice is about 150% pricier than
regular rice and ducklings are also sold as healthy food.)
