Why does the soil compact? How to eliminate?

The main reasons for the formation of soil citrus are as follows: 1. The acidity of the soil is too large or too small, such as acid rain. 2. Plastic products, such as plastic mulch, have not been cleaned up in time and cannot be completely decomposed in the soil. 3. Long-term single application of chemical fertilizers will not be able to be replenished in time for humus, which will also cause soil compaction and may also crack.

The consumed carbon comes from soil organic matter, and the low organic matter content affects the
