Microbial organic fertilizer refers to organic fertilizers with added microbial strains. Beneficial microorganisms in microbial organic fertilizers enter the soil and form symbiotic relationships with microorganisms in the soil, inhibiting the growth of harmful bacteria and transforming them into beneficial bacteria. They interact and promote each other, playing a synergistic role in the community, improving soil physical and chemical properties, and enhancing the ability of soil to retain water, nutrients, and supply nutrients. Microbial organic fertilizers also require fermentation process treatment.

process flow

1. Pre treatment of raw materials: including sorting, crushing, moisture content and carbon nitrogen ratio adjustment

2. Add microbial strains

3. Raw material fermentation: The cycle usually takes 15-20 days. Stage 1: Refers to the microbial metabolic process of aerobic fermentation in two stages: medium temperature and high temperature. It refers to the entire process from the early stage of fermentation, through medium and high temperatures, and then reaching a decrease in fermentation degree, which generally takes 10-12 days. Phase 2: The material undergoes a first stage fermentation, and there is still a portion of easily decomposable and a large amount of difficult to decompose organic matter present, which requires non continuous fermentation to mature. At this point, the temperature continues to decrease, and when the temperature stabilizes at around 35-40 ℃, it reaches maturity, usually taking 5-10 days. Attention: During the fermentation process, it is necessary to regularly flip and adjust the temperature of the fertilizer pile.

4. After fermentation, it is necessary to screen again to remove impurities, and then crush these screened impurities as necessary.

5. Form microbial fertilizers into granules or powders as needed
