Growing Maize in Laikipia

Soil suitability analysis based on Laikipia's nutrient profile

Quick answer

Yes, with the right inputs — Laikipia is moderately suited to Maize. Laikipia's soil (pH 4.99, strongly acidic) gives Maize a suitability score of 70/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Laikipia County is a solid choice for Maize, with a soil-match score of 70/100. At an average pH of 4.99 the soil is strongly 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 phosphorus — measured at N 1.42 g/kg, P 16.6 mg/kg, K 215 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 #9 soil match of the 106 crops we assess for Laikipia County. Maize's full potential is about 1,800 kg/acre (~KES 81,000/acre at KES 45/kg), but at Laikipia's 70/100 suitability a realistic target here is closer to 1,575 kg/acre (~KES 70,875/acre) unless the constraints above are addressed.
