Growing Maize in Kisii
Soil suitability analysis based on Kisii's nutrient profile
Yes, with the right inputs — Kisii is moderately suited to Maize. Kisii's soil (pH 5.21, strongly acidic) gives Maize a suitability score of 69/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Kisii County is a solid choice for Maize, with a soil-match score of 69/100. At an average pH of 5.21 the soil is moderately acidic, below Maize's preferred 5.5–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen and phosphorus — measured at N 1.09 g/kg, P 13.1 mg/kg, K 151 mg/kg against this crop's high/high/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Maize, which favours loam. On ShambaIQ's soil-match model, Maize is the #26 soil match of the 106 crops we assess for Kisii County. Maize's full potential is about 1,800 kg/acre (~KES 81,000/acre at KES 45/kg), but at Kisii's 69/100 suitability a realistic target here is closer to 1,553 kg/acre (~KES 69,885/acre) unless the constraints above are addressed.
