Abstract

Kinetical study on NON-EXCHANGEABLE POTASSIUM (NEK) release is necessary for management, optimum use of soil resources, availability and supplying power of potassium. Information about NEK RELEASE RATE in Golestan soils is limited. The aim of this study was to investigate the NEK release of saturated soil sample by calcium using acid citric and CACL2 extractants from 2 to 1844 h duration in 12 dominant soil series in Golestan province. Different soils indicated various responses to continuous extraction. The rate of K released in different soils was lower in CACL2 than that of CITRIC ACID. Potassium release was faster in earlier periods of the extraction in all soils followed by a lower RELEASE RATE. Due to high coefficient of determination and low value of the standard error of the estimate, the NEK release kinetic by CITRIC ACID and CACL2 were well described by Elovich and Parabolic DIFFUSION equations and Power, First order and Elovich equations, respectively. Therefore, NEK RELEASE RATE was controlled by K DIFFUSION from weathered surface of soil minerals.
