If the soil is completely saturated with water, air can not circulate through your pores and the roots can not perform their physiological functions. If the saturation is prolonged, the plants die. If temporary, the harvest decreases.

Moreover, drained soils are saturated with rain and then dried, resulting in shrinkage cracks, which facilitate the movement of water and air from the atmosphere. C. This helps drain the soil nitrification drainage promotes and enhances certain bacterial processes in soil that contribute to the decomposition of matter and the production of organic nitrogenous substances that serve as food for plants.
