Without fertilizers and pesticides, it is one of the goals of modern organic agriculture. A method for making natural organic fertilizers using raw materials is introduced.

Raw materials: 1500 kg of natural red soil, 150 kg of rice straw, straw, garbage, proper amount of grass and wood ash, and human excrement or pig, chicken, and duck droppings.

Method: Take 1500 kilograms of natural red loam, smash, take 150 kg of straw or wheat, sorghum, corn straw, mountain grass or flammable garbage, and burn red brown soil with grass or garbage. After mixing the burned red loam with the wood ash, move it into the room and pour on human excrement or pig, chicken or duck droppings while moving. Spread it until wet and mix it until it is piled up. Afterwards, every two days, two people shall be poured with human excrement, piled into a pile after turning, and after 75 days of continuous use, they can be used for another 15 days. After 90 days of tanning fermentation, after the decomposition of the microorganisms, the brown soil became dark brown with a nitrogen content of 5.6%, phosphorus pentoxide content of 1.3%, potassium oxide content of 1.8%, pH 7.5, and the porosity was relatively low. No odor. In this way, the organic fertilizer is successfully tanned and can be applied.

In short, the use of abundant natural resources in rural areas for the production of natural organic fertilizers has the advantages of easy material extraction, simple operation, low cost and no pollution, and is beneficial to the restoration of the original ecological balance of nature. The development prospect is very broad.
