Gaining Insights in Soil Fertility on Lixic Ferralsols: Linking Banana Productivity to Soil Nutrient Dynamics in Smallholder Farming Systems in South-Western Uganda

In Uganda, banana (Musa spp.) is an important crop supporting different stakeholders along its value chain. However, the increase in banana production under smallholder farming system is a result of the increased area of land under its cultivation. This has escalated land degradation in the form of soil nutrient exhaustion in the banana farming systems. Although, declining trends for banana productivity, has been widely reported, there is limited formidable information on the level of soil fertility decline in the banana-grown fields in relation to annual crop-grown fields, which also support livelihoods of smallholder farmers. Therefore, detailed comparison farm studies were conducted on banana and annual crop grown-fields on lixic ferralsols to gain insights on soil organic matter and chemical parameters of selected fields. While there were no significant differences in soil chemical properties (p
