Composting fertilizer is very simple. A small amount of compost only needs to put the compost materials into a big mouth container and fully soak them in water. Some dry materials should be soaked in more water and have some water surplus. Then, cover the lid and twist it slightly to leave room for ventilation. Because gas will be released during fermentation, the container will burst easily if the lid is too tight, and maggots will easily breed if the lid is not good.

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.
