Growing Maize in Makueni
Soil suitability analysis based on Makueni's nutrient profile
Yes, with the right inputs — Makueni is moderately suited to Maize. Makueni's soil (pH 7.5, alkaline) gives Maize a suitability score of 66/100. Match fertilizer to Makueni's nitrogen and phosphorus levels for the best result.
Makueni County is a solid choice for Maize, with a soil-match score of 66/100. At an average pH of 7.5 the soil sits above Maize's preferred 5.5–7 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.86 g/kg, P 29.6 mg/kg, K 351 mg/kg against this crop's high/high/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Maize, which favours loam. On ShambaIQ's soil-match model, Maize is the #51 soil match of the 106 crops we assess for Makueni County. Maize's full potential is about 1,800 kg/acre (~KES 81,000/acre at KES 45/kg), but at Makueni's 66/100 suitability a realistic target here is closer to 1,485 kg/acre (~KES 66,825/acre) unless the constraints above are addressed.
