Yes, with the right inputs — Makueni is moderately suited to Groundnuts. Makueni's soil (pH 7.5, alkaline) gives Groundnuts a suitability score of 65/100. Match fertilizer to Makueni's nitrogen and phosphorus levels for the best result.
Makueni County is a solid choice for Groundnuts, with a soil-match score of 65/100. At an average pH of 7.5 the soil sits above Groundnuts's preferred 5–7 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.86 g/kg), phosphorus (29.6 mg/kg) and potassium (351 mg/kg) all meet Groundnuts's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Groundnuts, which favours sandy. On ShambaIQ's soil-match model, Groundnuts is the #55 soil match of the 106 crops we assess for Makueni County. Groundnuts's full potential is about 500 kg/acre (~KES 45,000/acre at KES 90/kg), but at Makueni's 65/100 suitability a realistic target here is closer to 406 kg/acre (~KES 36,540/acre) unless the constraints above are addressed.
