The physical factors are climate, topography and soil. Rainfall, especially in drier areas such Ciskei, is the most important climatic factor determining agricultural production. Mean annual rainfall is the region in the long-term. It determines the broad agricultural potential of a region if the other factors of climate, topography and soil are not limiting to growth. it is then a reference point from which to start assessing a region's agricultural potential, but it does not provide information on the seasonal distribution of rainfall.en
