Organic fertilizer is mainly derived from plants and animals. Processed from biological materials, animal and plant wastes, and plant residues, the Production of organic fertilizer eliminates toxic and harmful substances and is rich in a lot of beneficial substances.
1. Use livestock manure to ferment organic fertilizer
Use chicken manure, pig manure, sheep manure, and other livestock manure as raw materials. The moisture content is controlled at about 40%. It contains about 1.6 tons of raw materials + 5 kg of EM stock solution + 2-3 kg of cornflour mixed and crushed. Stack them into strips with a width of 2 meters, a height of 1 meter, and unlimited length, and cover them with old sack pieces or straw curtains. Generally, the temperature of the stack can rise to about 50C within 24 hours. Within 48 hours, the temperature of the pile can rise to above 60C, or even as high as 70C. Such a temperature can make all the raw materials in the pile decompose in 5-7 days in spring, summer, and autumn, and the odor disappears, and the pathogenic bacteria and insects in the raw materials All eggs, grass seeds, etc. are killed. The fertilizer fermented by this method can be called ecological organic fertilizer or organic powder fertilizer. This fertilizer can be used directly on crops, or it can be pelletized and bagged, and sold as commercial organic fertilizer.
2. Use crop straws and other fermented organic fertilizers
Use organic waste such as straws, leaves, weeds, sawdust, distiller grains, and furfural residues as raw materials. First, control the moisture content of the raw materials to about 70%. If the moisture in the raw materials is less, pour it thoroughly with water to ensure proper moisture. Long crop stalks such as corn stalks and sorghum stalks need to be crushed. (Because the raw materials are too long, it is inconvenient for seed dressing and overturning.) After every 1,000 kg of dry raw materials are soaked and poured with water
It can be mixed with 5 kg EM stock solution + 1% bean cake or urea, sprinkle in the raw materials, turn over and mix well, and then pile into a strip pile with a width of 2 meters and a height of 1 meter with unlimited length, and cover it with a plastic sheet. After 24 hours, the temperature in the reactor can reach about 50C, and in 48 hours, the temperature can rise to about 70C. After several days of continuous high temperature, the temperature of the reactor gradually decreases. It takes about two weeks to ferment.
After the raw materials are all decomposed, the eggs, grass seeds, and pathogenic bacteria in the raw materials are all killed, the stalks turn brown or dark brown, and the pile collapses by 1/3 or 1/2 than when it was just piled. The fermented raw materials are soft and elastic when held by a hand, crisp when dry, and easily broken.
3. Using wastes such as livestock manure and crop straws to ferment organic fertilizer
Waste raw materials such as livestock manure + crop straws are used. Due to the complexity of various raw materials, the nutrient content varies. The nutrient content of various livestock and poultry manures is not the same, so we cannot list the individual production methods here. For example, when raw materials such as straw are mainly used for fermentation, about 20% of livestock and poultry manure can be added; when livestock and poultry manure is used as the main raw material, about 20% of straw powder can be added. The fermentation method is the same as described above. If fermented with more acidic raw materials, 1-3% lime powder should be added during fermentation to adjust the pH to neutral. The organic fertilizer fermented by this method is suitable for various crops and various soils.
4. Production of bio-organic fertilizer
Take the fermented organic fertilizer as the carrier. Bio-organic fertilizer processed by adding probiotics refers to a specific organic fertilizer containing fermenting microorganisms that are beneficial to crop growth. It not only has the effect of microbial fertilizer but also has the effect of organic fertilizer. Used in agricultural production, it has a significant yield increase effect.
The above fermented organic fertilizers can be pelletized and packaged using an Organic fertilizer production line and sold as commercial organic fertilizers.
