Soybean fermentation to do fertilizer has soil fermentation, soaking fermentation, fertilizer fermenter, natural fermentation of these four methods, respectively, the steps are as follows:

1, soil fermentation

The fresh soya bean dregs and moist fine soil in accordance with the ratio of 1:1-2 mixed evenly, and then Bury it inside the cement pool for fermentation, the top should be covered tightly with agricultural film, after 20-30 days it can be rotten.

2, soak fermentation

Prepare a clean plastic bottle, soybean residue into the bucket, if you are worried about too stinky, you can add some orange peel, a little white wine, rice vinegar, etc. together with the fermentation, to reduce the smell. Then add water to the bucket to cover the soybean dregs. Screw on the cap, and be careful not to screw the cap too tightly, or the gas produced during the fermentation process will blow up the bottle.

Put the plastic bottle into the sunshine, can speed up the fermentation speed. 1-2 days can open the bottle cap to release the gas in the bottle, to avoid blowing up. About 3 months, when the fertilized water turns black, it means the soybean residue has been rotted.

3, fertilizer fermentation agent

Used to ferment soybean dregs most of the fertilizer fermentation agent to fermentation, this fermentation agent is a kind of biological strains, are sold online. After buying back the fertilizer fermenter, mix the fermenter and soybean dregs evenly according to the ratio of 1:1000, and then put it into a container for fermentation, note that due to the high water content of soybean dregs, it must be dried out, or put it in a big iron pot and fry it.

When the temperature of the dregs in the container reaches about 70 degrees, it needs to be tipped, after a week of time to ferment, and then tipped again to find that there is no odor, the dregs of the white mycelium grows on the that is to say that the fermentation is successful, and vice versa, then continue to fermentation.

4, natural fermentation

In the winter, the temperature is relatively low, soybean residue can be used directly, but can only be used in the ground planted plants, in the distance from the plant's root system outside of the position of 20 centimeters, the soybean residue is buried in it, it can be slowly fermented to release the fertilizer.

Winter fermentation process, the release of heat, but also can be insulated, to enhance the temperature of a small area, and after a whole winter of fermentation, that allows the plant in the beginning of the spring, the growth of better.

Making Precautions for Soybean Fertilizer

When the temperature is high, the fermentation time of ten days will be enough; when the temperature is low, the time should be a little longer. Because the bottle of material to be fermented, so can not be filled too full, eight or nine percent full can be; bottle mouth also do not have to screw too tight, leaving a little gap. Fermented soybean fertilizer water should be properly diluted when used.
