Abstract

The release rate of NONEXCHANGEABLE K (NEK) plays a significant role in supplying available K, particularly in soils containing K bearing minerals. Information about NEK release rate in soils of Iran is limited. The main objective of this research work was to investigate the KINETICS of NEK release in 4 soil orders, Aridisols, Mollisols, Alfisols and Inceptisols of Golestan Province by successive extraction with 0.01 M CaCl2 over a period of 264 h. The results showed that the amount of NEK release after 264 h ranged from 1984 mgKg-1 in Alfisols to 915 mg Kg-1 in Inceptisols. High clay content, NONEXCHANGEABLE K and cation exchange capacity and also presence of potassium bearing minerals (illite and Hydroxy Interlayer Vermiculite), in Alfisols, are the main reasons for the high NONEXCHANGEABLE K release in these soils. In all soils, rate of potassium release was higher in the begining and decreased, afterwards. The KINETICS of cumulative NEK release were evaluated by using the Elovich, zero order, parabulic diffusion law and first order equations. Du to the lowest coefficient of determination (r2) and highest standard error (SE), the Elovich and zero order equations could not describe the NEK release KINETICS. In contrast, parabulic diffiusion law and first order equations fitted to the observed data satisfactorily, indicating that diffiusion mainly controlled the K exchange. Rate constants were very different in soil samples. Which is mainly attributed to difference in particle size distribution, clay content and the type of clay minerals.
