Preparation of soil: arrangement of the soil includes loosing and converting it. The following are the advantages of the preparation of the soil:

2. Loose soil improves the growth of worms and bacteria in the earth. They, in turn, replenish nutrients to the earth and support an additional loosening of the clay.

3. Changing and loosening of earth draws nutrient-rich earth to the cover. Plants can then consume these nutrients more quickly.
