The results calculated by the Elovich rate equation showed that K release rates from 1 mol.L-1 HNO3 extraction ＞those from 2 mol.L-1 HNO3 extraction ＞those from H-resin extraction. Elovich equations combining with the data of H-resin and 2 mol.L-1 HNO3 successive extraction could well described the release characteristics of soil K. The correlation coefficients of the equations reached most significant levels (r＝0.956**—0.999**), and standard errors of specific K release capacities between the vaules calculated by the equations and those measured by both successive extractions were smaller(s=1.61 and 3.52). The specific release rates of soil K calculated by the Elovich rate equations were significantly correlated with the indices of soil K availability (the amounts of easily available K, nonexchangeable K, total available K in soils and K absorbed by ryegrass).
