Nature and properties of some cultivated entisols under peach orchards

Abstract

Entisols have developed from Quaternary deposits in northwestern Turkey under xeric moisture and thermic temperature regimes. The morphological features and physico-chemical properties of ten soil profiles representing the major Entisols under Mediterranean climate in northwestern Turkey were studied. These soils show a similar variation in morphological, physical, and chemical properties as a result of similar parent material, topography, climate, and vegetation. Entisols were developed in the 700 mm precipitation zone. These soils occur in nearly flat areas and are characterized by being dry in summers and moist in winter months. It is believed that present agricultural practices are degrading Entisols in this area.
