    (iii) Floods: Floods are another most important cause responsible for the soil degradation in terms of quantity as well as quality.
    (iv) Deforestation: Large-scale forest destruction by man to fulfill their own needs is one of the major causes responsible for soil destruction.
    (v) Overgrazing: It reduces the usefulness of the land and is one of the causes of desertification and erosion.
    (vi) Overuse of chemicals: Excessive use of fertilizers and pesticides to increase the agricultural production is one of the major causes for soil pollution.
    (vii) Urbanization: Large-scale urbanization is the major cause for the destruction of fertile soil due to encroachment of the fertile areas.
