The benefit of turning over the soil would be that the nitrogen content of the soil would increase.
Roots may draw atmospheric nitrogen and convert it into nitrates, which plants can use. The amount of nitrogen in the soil would rise if these roots were ploughed into the ground. The airflow can be improved by loosening the soil. The plant may be held securely by the roots since they can grow deeper into the earth. Plowing improves the soil's ability to retain water. In addition to uprooting weeds from the field, ploughing promotes the development of beneficial microbes.
Also, in the absence of plowing, the roots can start to decay. Numerous essential soil animals and microorganisms will also perish.
