| Abstract: | In this paper, some aspects affecting ammonium fixation and the availability of nonexchangeable-ammonium to plants, involving clay mineral composition, organic matter, soil water content, the redox of iron, the status of potassium in soils and the homogeneity of different interlayer surface charge and so on, are reviewed. Moreover, the methods of determining nonexchangeable-ammonium in soils are also discussed. |
