With strip or trough compost, the compost temperature can rise to about 50℃. Within 48 hours, the stack temperature can rise above 60°C, or even as high as 70°C. Such a temperature in spring, summer, and autumn can make all the raw materials in the pile decompose in 5-7 days, the odor disappears, and all the pathogenic bacteria, insect eggs, and grass seeds in the raw materials are killed. Fertilizer fermented by this method can be called ecological organic fertilizer or pollution-free organic fertilizer, which can be directly used on crops.
Two methods and production processes for making bio-organic fertilizer using bio-organic fertilizer equipment
There are two common production methods for bio-organic fertilizer, namely, mixed fermentation of manure straw and fermentation of livestock and poultry manure. The equipment for making bio-organic fertilizer includes composter equipment, crushing equipment, mixing equipment, granular equipment and so on.
- Use livestock manure and crop straws and other wastes to mix and ferment organic fertilizer. When using crop straw and other raw materials for fermentation, about 20% of livestock manure can be added, and when using livestock and poultry manure 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.
- Use livestock manure to ferment organic fertilizer. Use chicken manure, pig manure, sheep manure and other livestock manure as raw materials. The water content is controlled at about 40%, and it contains about 1.6 tons of raw materials + 5 kg of probiotic liquid + 2-3 kg of corn flour mixed and mixed and crushed.
