with digestion. fermented seawater mixed with brv and wsc and fed to chickens can be used to prevent feather loss in chickens during the summer. composting lab can reduce damage to compost by neutralizing ammonia gas produced by immature compost. pest management fpj and/or ffj diluted with rice bran and water can preferentially attract pests away from crops. aphids can be controlled with 0.7 litres of soap water mixed with 20 litres of water. alternatively, use hpw. apply to the plant as a foliar spray. to control mites, dilute soap water 40x with water. alternatively, use hpw. insect attractants knf insect attractants are non-toxic methods of pest control. during the egg-laying season. aia and fia devices are installed at the height of fruits or leaves in and around the field. they are usually employed during the peak of the reproductive growth of fruit-bearing plants and during the height of vegetative growth of leafy vegetables. aromatic an aromatic insect attractant (aia) is a mixture of alcohol and rice wine or brandy and ffj or fpj (diluted 300:1) in an open container hung when pests lay their eggs. fluorescent a fluorescent insect attractant (fia) uses a zinc sheet bent in an "l" shape hung so that the shorter side acts as a roof and the other side hangs vertically. a fluorescent light hangs vertically from the corner of the sheet to attract pests. a water-filled basin containing a few drops of gasoline/kerosene hangs underneath the light to kill insects that alight. soap water and hot pepper water soap water (sowa) and hot-pepper water (hpw) are used for controlling aphids and mites. when soap water is applied as a foliar spray, sunlight evaporates the water. evaporation, heat loss and condensation kill the pests. sowa is chopped lye soap, boiled in water to make a thick soup and then diluted. hpw is chopped hot peppers, boiled and diluted. experience united states in hawaii, crop productivity increased 2-fold with the use of knf, while reducing water use by 30% and eliminating the use of pesticides. cane grass proved to be a superior cover crop on degraded hawaii fields. south korea natural farming was adopted by the south korean government after successful trials growing rice in one county, where every farmer followed the practice. they increased yields, saved money on inputs and obtained a price premium. rivers and coastal waters experienced environmental benefits. a co-op of 40 strawberry farmers used knf exclusively in 300 foot-long greenhouses, producing increasing output and obtaining a higher price. in another experiment, farmers in an entire county used knf to become self-sufficient, with each farm raising 500 chickens, 20 pigs and 5 beef cattle. mongolia in the gobi desert in mongolia, harsh wind and minimal rainfall defeated three attempts to plant trees. with knf, the trees had a 97% survival rate and as of 2014 had reached 20 feet in height. corn and barnyard grasses provide livestock feed. watermelon farming provides a stable income to farmers there. china the chinese army feeds its service members using its own resources. for the beijing olympics, it brought pigs into the city, setting off violent protests over the odour. it then dispatched two officials to south korea to study natural farming. knf techniques successfully eliminated the odour. the university of peking now offers masters and phd programs in knf.
