AbstractAn account is given of physical conditions that have been found in the profiles of cultivated soils in the eastern region. The origin of some of them is discussed. Many are of pedological origin, others result from cultivation. The origin and causes of adverse physical conditions, e.g., slaked structures, drainage patterns and pans, should be understood and treatment based on them. Cultivations, generally, should be related to soil conditions and the changes that are likely to occur in soil structures during the growth of crops.
