Harare (Zimbabwe). 1993. p. 1-15Summary: Soil erosion from low-fertility sandy soils in Zimbabwe's communal areas is a major problem. The main factors causing soil degradation are inappropriate livestock management and poor cropping technology. The latter is due to insufficient knowledge concerning appropriate permanent cultivation techniques under tropical rainfall and soil conditions. The existing tillage method is characterised by clean cultivation, which begins with inversion tillage, followed by clean weeding through hoeing. These practices encourage water erosion under the prevailing rainfall pattern. Therefore one pressing research need in Zimbabwe is to reduce soil erosion in the communal areas through improved tillage systemsCollection: AGRIS Collection
