How to produce organic fertilizer?

Produce organic fertilizer is a very important environmental protection undertaking, which can help alleviate land pollution, improve soil quality, promote agricultural production and many other issues. This article will introduce How to produce organic fertilizer from the aspects of organic fertilizer raw material collection, fermentation treatment, ingredient mixing, drying and sterilization, sieving and grading, packaging and storage.

1. Raw material collection of organic fertilizer

Raw materials for organic fertilizers can be livestock and poultry manure, crop residues, wood chips, corncobs, sawdust, etc. Raw materials should have stable sources, stable quality, and no harmful chemicals. The collected raw materials need to be pre-treated, such as crushing, sieving, drying, etc., for better subsequent processing.

2. Fermentation treatment of organic fertilizer

Fermentation treatment is a key step of produce organic fertilizer, it can decompose raw materials, detoxify and increase nutrients. Two methods of high-temperature fermentation or low-temperature fermentation can be used for fermentation treatment. High-temperature fermentation needs to be fermented at high temperature for 7-10 days, and the temperature must reach above 50°C to kill harmful microorganisms and insect eggs. Low-temperature fermentation requires 2-3 weeks of fermentation in a lower temperature environment, the temperature generally does not exceed 30°C, in order to promote the decomposition and maturity of organic matter.

3. Mixing of organic fertilizer ingredients

Ingredients mixing is to mix the fermented raw materials and other additives (such as phosphate, nitrogen source, carbon source, etc.) to achieve proper nutrients and pH. The requirements for ingredient mixing are very high, and the speed and temperature of the Fertilizer mixing machine need to be strictly controlled to avoid deterioration and spoilage.

4. Drying and sterilization of organic fertilizer

Dry and sterilize the mixed materials to remove moisture and eliminate microorganisms such as bacteria and viruses. Drying can be done by tumble drying. Sterilization can adopt methods such as high-temperature sterilization and ultraviolet sterilization. The quality of the organic fertilizer after drying and sterilization can be guaranteed.

5. Screening and grading of organic fertilizer

Sieving and grading is to sieve the dried and sterilized organic fertilizer to remove sundries and unqualified materials. The quality of screening and grading directly affects the particle size and uniformity of organic fertilizers.

6. Packaging and storage of organic fertilizer

Qualified organic fertilizers are packaged and stored for use. The storage of organic fertilizers needs to be protected from moisture and humidity to avoid deterioration and spoilage. At the same time, the storage environment should comply with local environmental protection and hygiene requirements to ensure product quality and safety.

To sum up, to produce organic fertilizer, it must go through several steps such as collection of raw materials, fermentation treatment, ingredient mixing, drying and sterilization, sieving and grading, and packaging and storage. In the production process, it is necessary to pay attention to controlling conditions such as temperature, humidity and oxygen concentration to avoid deterioration and spoilage. At the same time, produce organic fertilizer needs to comply with local environmental protection and sanitation requirements to ensure product quality and safety.
