The Content Of Available And Slowly Available Potassium On Kahramanmaraş Plain, Gufran Geyi̇k, Kadi̇r Yilmaz

Turkish Journal of Agriculture and Forestry

The aim of this study was to determine the available and slowly available potassium capacity of soil samples collected from the Kahramanmaraş plain. Slowly available potassium content was determined by the HCl extraction method. Slowly available potassium was found at between 3 and 46 mg 100 g^{-1} at a depth of 0-15 cm, 1 and 33 mg 100 g^{-1} at a depth of 15-30 cm and 1 and 25 mg 100 g^{-1} at a depth of 30-45 cm. Slowly available potassium content decreased along with soil depth. Available potassium content also decreased with soil depth. A significance correlation (0.1%) was …
