Skillful production of Organic Fertilizer from Rice Straw

The elimination of chemical fertilizers and pesticides is one of the goals of modern organic agriculture. Through several years of practical experience, the author found a way to make natural organic fertilizer by using original ecological materials. Raw material natural red soil 1500 kg. Straw, straw, garbage 150 kg. Human feces or pig, chicken, duck feces a number of. 1500kg of natural red soil is prepared by retting, mashed, straw or wheat, sorghum, corn (2343,-3.00,-0.13%) straw, mountain grass or combustible garbage 150kg is taken, the ratio is 10:1, and the red soil is burned to brown with grass or garbage. After mixing the red soil and plant ash, move it into the room, pour human excrement or pig, chicken and duck excrement while moving, pour it until it is wet, mix it evenly and pile it up into a pile. After every two days poured on two loads of human excrement, turned into a pile, after 75 consecutive days, and then placed for 15 days can be used. After 90 days of fermentation and microbial decomposition, the brown manure turned dark brown, with nitrogen content of 5.6%, phosphorus pentoxide content of 1.3%, and potassium oxide content of 1.8%. pH 7.5, and relatively loose, basically no odor. In this way, the organic fertilizer will be retting successfully, can be applied. Why should red soil be used for analysis? Do not dig the soil of the field tillage layer, first, to avoid destroying cultivated land. Second, red soil is rich in acidity, does not contain disease bacteria, insect eggs, etc., does not contain other substances that do not dissolve in water. After burning, red soil becomes the symbiotic carrier of N, P and K. In addition, why should the burned red soil manure be moved indoors, because the temperature and humidity can be artificially controlled, which is conducive to the fermentation of natural organic fertilizer. Organic fertilizer will produce high heat (40℃~75℃) during fermentation and decomposition, which can kill disease bacteria, insect eggs, etc., and then slowly decompose into semi-ripe fertilizer at an appropriate temperature (40℃~50℃). At the same time, a large number of beneficial microorganisms can be cultivated during decomposition, which is conducive to plant absorption. In short, the use of rural rich natural resources to produce natural organic fertilizer, easy to obtain materials, simple operation, low cost, no pollution, conducive to restoring the original ecological balance of nature and other advantages, the development prospects are very broad.
