| Popis: | The dissolution of two finely ground potassium feldspar rocks (KFR). from Malawi and Sri Lanka, was examined in four indigenous acid soils using open-leaching and closed-incubation systems. Increases in fractions of soil potassium (K), compared to the control, indicated that the extent of dissolution of KFR was usually substantially enhanced in the leaching system. Because the leaching system represents the field situation more closely, it is the most appropriate for assessing the dissolution of potassium feldspar rocks (KFR) in soils and their potential as direct-application K fertilisers. |
