Answer: Cao Weixian, a senior agronomist from the Yangling Association for Science and Technology and a senior agronomist at Yangling Vocational and Technical College, said that the temperature drops in winter and the amount of ground evaporation decreases. In order to retain water and fertilizer, it can be done by covering the ground with organic materials such as straws, weeds, leaves, etc., which can reduce water evaporation and increase soil organic matter and nutrients (after plowing into the soil for decomposition in the coming year). The soil can also be raked and plowed before overwintering to create a granular structure, reduce ground cracks and prevent water loss.
