Growing Sweet Corn in Murang'a

Soil suitability analysis based on Murang'a's nutrient profile

Murang'a County is a solid choice for Sweet Corn, with a soil-match score of 62/100. At an average pH of 5.03 the soil is moderately acidic, below Sweet Corn's preferred 5.8–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is phosphorus — measured at N 1.2 g/kg, P 12.2 mg/kg, K 168 mg/kg against this crop's high/high/medium demand — so the fertilizer plan below prioritises closing that deficit. Sweet Corn prefers loam soils, while Murang'a is largely clay, so drainage and organic-matter management matter more here. Sweet Corn's full potential is about 8,000 kg/acre (~KES 320,000/acre at KES 40/kg), but at Murang'a's 62/100 suitability a realistic target here is closer to 6,200 kg/acre (~KES 248,000/acre) unless the constraints above are addressed.
