Why fermentation before organic fertilizer production?

Organic fertilizer production line is made of fresh chicken manure and pig manure, and it does not contain any chemical components. However, chicken and pig have poor digestion ability, which can only consume 25% of nutrition, while 75% of the other nutrients in feed are discharged with feces.

Therefore, the dry products contain nitrogen, phosphorus, potassium, organic matter, amino acid, protein and other components.

The reason of fermentation in organic fertilizer production line

(1) In the fermentation process of organic fertilizer production line, the odor produced by compost should be prevented and controlled, and secondary pollution should be avoided. Adding fermentor or fast decomposing bacteria in compost can reduce odor in a short time, and the sensory effect is good. Or the odor produced by composting plant can be treated by biological deodorization technology.

(2) In the process of organic fertilizer production, the factors that affect the fermentation and microbial reproduction of organic waste must be effectively controlled. The main factors are the organic matter content, water content, C / N ratio, oxygen concentration and temperature and pH value in composting process.

On the one hand, the carbon nitrogen ratio, temperature, humidity, pH value, oxygen content and other nutrients needed for the growth and reproduction of each microorganism strain were satisfied by various factors; On the other hand, different nutrient content will produce different fertilizer effects.

For example, high carbon content can increase soil fungi, nitrogen elements help increase soil bacteria, and calcium has a significant effect on the resistance of crops.

(3) Strictly control the heavy metal content in raw materials to prevent microbial poisoning in the later production process, and the heavy metal content in the organic fertilizer products exceeds the standard, and pollutes the soil and crops.

(4) After analysis and detection, the content of trace elements such as organic matter, humic acid, nitrogen, phosphorus, potassium and the number of living bacteria should meet or exceed the national standards.
