The use of farmyard manure for organic fertilizer production mainly includes two parts, the early fermentation and the later granulation production. The organic fertilizer production equipment mainly includes: tumbling machine, automatic batching system, disc mixer, organic fertilizer granulator machine, dryer, chain pulverizer, trommel screen, coating machine, packaging scale, cyclone dust collector, conveyor . Why should farmyard manure be fermented in the early stage of organic fertilizer production? Because unfermented organic fertilizers are harmful, let's take a look at what are the hazards.
1. Sensitive disease
The excrement contains pathogens and diseases such as salmonella and ciliates. Immediate application will speed up the spread of diseases, and the onset of crops will also have adverse effects on the physical and mental health of edible agricultural products; when the organic chemical compounds at the soil level are not composted, it is easy to Breeds of pathogens and pests, which can also lead to the occurrence of green plant diseases.
2. Fermented and burnt seedlings
After alcohol-free raw manure is applied to the field, alcohol is initially produced in the raw manure when alcohol standards are met. If the alcohol is located close to the roots and the crop leaves and stems are smaller, the heat caused by the alcohol can damage the development of the crop, and when is it more severe? The leaf stem unfortunately died.
3. Hazardous substances
Throughout the melting process, harmful substances such as methane gas, gas, ammonia can cause acidity and underground stem damage to soil levels and crops.
4. Hypoxia at the soil level
Soil organic matter consumes CO2 at the soil level during the entire thawing process, making the soil level short of oxygen and inhibiting the growth and development of crops.
5. Soil organic matter is slow
The organic chemical state or slow-release state is common in unfermented organic fertilizers and cannot be immediately digested and absorbed by crops. Only when it is melted into a super-strong state can it be digested and absorbed by crops. Therefore, the immediate use of unfermented organic fertilizer will reduce soil organic matter.
