Composting bean dregs fertilizer is very simple. For a small amount of compost, just put the compost materials into a big mouth container, add water to soak them fully, and add more water to some dry materials, so there should be some extra water. Then cover it and twist it slightly to leave room for ventilation. Because gas will be released during fermentation, the lid is too tight and it is easy to burst the container.
The suitable retting time depends on different seasons. It is easy to ferment at high temperature in summer, and it can be fermented in1~ February, and fertilization in winter needs to be used in the following spring. Generally, after retting, the fertilizer will change its original color and become darker, some will turn black, and some will become sauce-colored. Some people think that cooked fertilizer is not smelly, which is wrong. Cooked fertilizer always smells. Therefore, it is more practical to determine the retting time.

Precautions:
(1) Do not use moldy and deteriorated raw materials or raw materials with peculiar smell as fermentation raw materials. If the fermented product is moldy or stinky due to improper preservation, it cannot be used to feed animals.
(2) When filling the pool, it should be sealed, but it cannot be compacted.
(3) When feeding in containers or bags, the containers should be sealed immediately and should not be exposed for too long, so as to avoid pollution, corruption and deterioration.
(4) Store in a cool and dry place. If the fermented material is to be stored for a long time, it should be sealed and compacted, and the air in the packaging bag should be exhausted as much as possible. This can not only be stored for a long time, but also degrade during storage. After a long time, the digestion and absorption rate will be better and the nutrition will be better. It can also be dried and stored in a jar.
