How to ferment bean cake fertilizer quickly? How long does it take for the bean cake to be used?

Bean cake fertilizer is a very common organic fertilizer. It is mostly used in fields where farmers grow vegetables and crops. It can also be used for growing flowers. Bean cake fertilizer is made by fermenting soybean residue after oil extraction. So how can bean cake fertilizer be fermented quickly?

How to ferment bean cake fertilizer quickly

The fermentation of soybean cake needs to meet the following conditions:

The first is proper moisture. If the moisture is too little and the bean cake is too dry, it will not ferment. Therefore, the bean cake needs to be given proper moisture before fermentation.

The second is a moderately high temperature. The so-called moderately high temperature means that it cannot exceed the inactivation temperature of the fermentation bacteria. Under this premise, the higher the temperature, the faster the fermentation.

Third, avoid light appropriately. Do not ferment in an environment exposed to direct sunlight.

Fourth, a small amount of oxygen is necessary. The fermentation process of bean cake requires a small amount of oxygen. Deterioration under anaerobic conditions does not belong to fermentation.

How long does it take for bean cake to be fermented before it can be used?

Special organic fertilizer fermentation agents can be added to the crushed bean cake to quickly ferment and mature it. During fermentation, it is necessary to pay attention to the humidity and temperature of the bean cake and adjust the humidity according to the instructions of the fermentation agent.

If there is no fermentation agent, the natural fermentation time will be longer. Spread the crushed bean cake on the cement floor to a height of about 15 cm, then sprinkle water evenly on the bean cake, stir the bean cake while sprinkling water, so that it absorbs water evenly, and the water content is generally around 55%. The specific standard is to hold it in the hand and make it into a ball, without water dripping between the fingers, and it will fall apart when it falls to the ground.

Then add water to the bean cake and pile it into a trapezoidal pile with a width of 1 meter, a height of 1 meter and an unlimited length, and then cover it with a layer of film. After 3 to 4 days, uncover the film and turn the pile over, turn the bean cake on the surface of the pile into the middle of the pile, and turn the bean cake in the middle of the pile to the outside. After turning over, cover it with film and continue to ferment. Turn the pile over every 5 to 6 days, and turn it over 4 times in total, and the bean cake will be thoroughly fermented and mature.

In summer, the temperature is high and the fermentation time is short. In winter, the temperature is low and you need to take good warming measures. If the fermentation volume is large, you need to turn it over every few days. If the volume is small, you can put it in a relatively sealed container for fermentation, but do not seal it completely to avoid accidents.

How long does it take for bean cake to be fermented and used as fertilizer?

Using biofertilizer fermentation agent or HM composting agent to assist fermentation can shorten the fermentation period, usually 10 to 15 days. The method is the same as the first method, except that the biofertilizer fermentation agent or HM composting agent is added to the water and mixed with the bean cake, which reduces the number of turning the pile in the middle.

No matter which method is used, the fermented bean cake can smell a mellow aroma, and white actinomycetes can be seen on the surface of the bean cake.
