How to ferment soybean to make fertilizer

Step 1: 1 bottle of Nongshengle strain + 1 kg of brown sugar + 15 kg of water, sealed and placed for 3-7 days for activation.

Step 2: After activation, dilute 20-50 times with water and mix evenly with the soybeans to be fermented.

Step 3: Seal the mixed soybeans in bags (buckets) and ferment for 2-7 days.

Note: The soybean fermentation process is anaerobic fermentation, which needs to be sealed to complete, and must not be exposed to oxygen.

Extended Information:

The biggest difference between fermentation and other chemical industries is that it is a chemical reaction carried out by living organisms. Its main features are as follows:

1, the fermentation process is generally a biochemical reaction carried out at room temperature and pressure, the reaction is safe and the required conditions are relatively simple.

2, the raw materials used in fermentation are usually starch, molasses or other agricultural by-products, as long as a small amount of organic and inorganic nitrogen sources can be added to carry out the reaction. Microorganisms can selectively utilize the nutrients it needs due to different categories. Based on this characteristic, it is possible to utilize wastewater and waste etc. as raw materials for fermentation for the transformation and renewal of biological resources.

3, the fermentation process is accomplished through the auto-regulation of the organism, the reaction is highly specialized, and thus a single metabolite can be obtained.

4, due to the organism itself has the reaction mechanism, can be specific and highly selective for some of the more complex compounds in specific parts of the oxidation, reduction and other chemical transformation reaction, can also produce more complex polymer compounds.

5, in general, the fermentation process requires special control of the production of stray bacteria. The usual methods of controlling stray bacteria are strict sterilization of equipment, heating and sterilizing operation of air as well as automation of the fermentation process as much as possible. Usually, if the fermentation process is contaminated with stray bacteria or phages, it will affect the fermentation process, resulting in a reduction in the yield of the fermented product, and in severe cases, it may even lead to the failure of the entire fermentation process and the fermented product will be required to be poured out completely.

6, microbial strain is the fundamental factor for fermentation, through mutation and strain screening, you can obtain high-yield strains and make full use of the production equipment, and even obtain the products that are difficult to produce according to conventional methods.

7, industrial fermentation and ordinary fermentation, compared with the more stringent control of the fermentation process, the requirements of the fermentation technology is more mature, and can realize the large-scale mass production

Based on the above characteristics, industrial fermentation is increasingly attracting people's attention. Compared with the traditional fermentation process, modern fermentation engineering has its superiority in addition to the above fermentation characteristics. In addition to the use of microorganisms, but also with plant and animal cells and enzymes, but also with artificial construction of the "engineering bacteria" to carry out the reaction; reaction equipment is not only the conventional fermentation tanks, but a variety of bioreactors instead, automation and high degree of continuity, so that the level of fermentation in the original basis of the level of improvement and and innovation.
