Abstract: Data were analysed using the Statistical Package for Social Sciences Version 22 computer program for descriptive attributes. Relationships between dependent and independent variables were determined using the tobit regression model. According to the findings, 85% of households are headed by men, with over 82% being post-primary graduates, who are the main decision makers. The majority (83%) cultivate 2 ha and 57% acknowledged food insecurity, with 89.1%, 73.1%, and 45.1% blaming it on climate variability, limited soil moisture, and a lack of input access, respectively. Low fertility scored 40% at medium level with labour at 40% in low cluster constraints, could be because of high unemployment rates. Animal manure and chemical fertiliser use were reported at 95.5% and 76.6%, respectively, although they were using them separately, probably due to high cost, increased labour requirements, and accessibility problems resulting in continuous low yields. Therefore, huge prospects of integrated soil fertility management practices’ use exist in the Kenyan semi-arid, especially when promoted at community level.
