What are the methods of composting in ancient China?

Composting with miscellaneous fertilizers can be said to be the origin of composting in China? As early as the Spring and Autumn Period and the Warring States Period, China had used the high temperature in summer to rot weeds in the fields as fertilizer?

In the Song Dynasty, Chen Fang introduced a method of retting fertilizer in Nong Shu, that is, stacking chaff and rotten leaves in a pool, and then collecting dish-washing fertilizer and rice swill for retting. Will it rot into fertilizer after a long time?

Another composting method was introduced in Shen Shi Agricultural Book in the Ming Dynasty, that is, Chinese milk vetch or silkworm soybean milk were piled together and fermented with river mud and a knife. This method is called "cellar flowers and plants" and "cellar silkworm soybean milk". Now it is called cellar grass pond mud in the south?

Manure accumulation method is recorded in Qi Yaomin's Book, which is a kind of accumulation method combining padding with accumulated fertilizer? At that time, it was called trampling method, which was actually the earliest compost in China?
