An overview of the principle of organic fertilizer fermentation

The production of any kind of qualified and high-quality organic fertilizer must go through the compost fermentation process.

Composting is a process in which organic matter is continuously degraded and stabilized by the action of microorganisms under certain conditions, and a product suitable for land use is produced.

Composting is an ancient and simple method of processing organic wastes and making fertilizers. With the deepening of research and the improvement of methods, its application has attracted great attention in various countries, because it has good ecological significance and also brings benefits to agricultural production. to benefit. There are many reports that the preparation of seedbeds with decomposed compost can inhibit soil-borne diseases.

And the antagonistic bacteria that follow after the high temperature stage of the composting process can make the number of bacteria reach a very high level; during the composting process, under the action of microorganisms, each organic matter reaches a state that is not easily decomposed, stable, and easily absorbed by crops; Reduce the toxic effect of heavy metals within a certain range.

It can be seen that composting is a simple and effective method to manufacture bio-organic fertilizer, which is beneficial to the development of ecological agriculture.

Most organic fertilizer products in my country are only composted and fermented for 15-20 days, and such products can only reach the harmless standard. The fermentation process of high-quality organic fertilizer compost generally takes 45-60 days. This is because harmful microorganisms such as plant pathogenic bacteria, insect eggs, and weed seeds will be killed in the heating stage and high temperature stage in the early stage of composting, but the main role of microorganisms in this process is metabolism and reproduction, and only a small amount is produced. metabolites, and these metabolites are unstable and not easily absorbed by plants.

In the later cooling period, microorganisms will humify organic matter and produce a large number of metabolites that are beneficial to plant growth and absorption in the process. This process takes 45-60 days. Composting through this process can achieve three purposes, one is harmless; the other is humus; the third is a large number of microbial metabolites such as various antibiotics, protein substances, etc.
