Özet

Non-exchangeable and exchangeable potassium (K) contents in relation to clay mineralogy of the 105 soil samples collected from 35 soil series in the Hilvan area of the upper Mesopotamia in the southeastern Anatolia were studied. It was concluded that the major part of the non-exchangeable K is located in the clay fraction which is predominantly of smectite, with some kaolinite and a small amount of paligorskite. In addition, a strong positive correlation between the non-exchangeable and exchangeable K fraction indicated that as the non-exchangeable K increases, the amount of exchangeable K also increases, resulting in higher buffering capacity of soils in terms of K than that of soils low in non-exchangeable K.
