Eliminating the use of fertilizers and pesticides is one of the goals of modern organic agriculture. Through years of practical experience, the author has found a way to make natural organic fertilizers using original ecological materials.
Raw natural red soil 1500 kg. Straw, straw, garbage 150 kg. Human excrement or pig, chicken, duck manure.
æ²¤ 1500 1500 kg of natural red soil, chopped, straw or wheat, sorghum, corn straw, mountain grass or combustible garbage 150 kg, the ratio is 10:1, red soil is browned with grass or garbage. Stir the red soil and the ash, and then move it into the room. While moving, pour the manure or pig, chicken, and duck manure, and moisten it. Stir well and pile it up. Two manures were poured into the manure every two days, and then piled up in a pile. After 75 days, it can be used for another 15 days. After 90 days of tanning fermentation, after the microorganisms were decomposed, the brown soil became dark brown with a nitrogen content of 5.6%, a phosphorus pentoxide content of 1.3%, and a potassium oxide content of 1.8%. The pH is 7.5, and it is relatively loose and has almost no odor. In this way, the organic fertilizer is successfully produced and can be applied.
Why do you want to use red soil? Do not dig the soil of the field tillage layer, one is to avoid destroying the cultivated land. Second, red soil is rich in acid, free of diseased bacteria, insect eggs, etc., and does not contain other substances that are not dissolved in water. The red soil after incineration becomes a symbiotic carrier of NPK fertilizer. In addition, why should the red soil dung after incineration be moved into the room, because the temperature and humidity can be artificially controlled, which is beneficial to the fermentation of natural organic fertilizer. Organic fertilizer will produce high heat (40 Â° C ~ 75 Â° C) in the process of fermentation decomposition, can kill diseased bacteria, insect eggs, etc., and then slowly decompose into semi-ripe fertilizer at a suitable temperature (40 Â° C ~ 50 Â° C), while decomposing can be cultured A large number of beneficial microorganisms are beneficial to the absorption of plants.
In short, the use of abundant natural resources in rural areas to produce natural organic fertilizers is easy to obtain, simple to operate, low in cost, non-polluting, and conducive to restoring the original ecological balance of nature, and has a broad development prospect.
