| Abstract: | Using hyperbola function y=yo-t/(a+bt) as the model of soil zinc fixation is suitable to analyse and forecast the changes of zinc availability of calcium, neutrial and acidic purple soils after zinc is applied. The rates of soil zinc fixation (y/t) and the maximum amounts of zinc fixation (1/b) increase with the increation of the applied zinc. Soil characterized rate of zinc fixation (V_(fix)) values is mainly determined by the kind of soils, not relating to the levels of applied zinc, So, it can be used as the index of soil zinc fixation capacity. |
