pinabutterjam:coolthingoftheday:Farmers in Indonesia introduce fish into their rice fields. The fish excrement acts as a fertilizer for the plants, while the plants attract insects and other pests, which serve as food for the fish. This process increases rice yield by up to 10%. Fish + ducks + azolla in rice fields is an amazing combo. No need for fertilizers, pesticides, nor herbicides. The movement of the fish also strengthens rice stalks, so it’s less likely to be destroyed by weather. Additionally, you can use azolla to feed livestock and add nitrogen to soil. -- source link
