Bush fallowing is necessitated by a reduction in soil fertility. The process of continuous cultivation of land leads to the depletion of soil nutrients, which makes it difficult for crops to grow properly. To address this, farmers practice bush fallowing, which involves leaving the land fallow for several years. During this period, the land is allowed to regenerate and restore soil fertility. The practice is also used to control pests and diseases that may have accumulated in the soil due to continuous cultivation. Therefore, the primary reason for bush fallowing is to restore soil fertility and maintain crop productivity.
