Growing Sweet Corn in Nyeri

Soil suitability analysis based on Nyeri's nutrient profile

Nyeri County is a solid choice for Sweet Corn, with a soil-match score of 69/100. At an average pH of 5.23 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 nitrogen and phosphorus — measured at N 1.09 g/kg, P 15.5 mg/kg, K 192 mg/kg against this crop's high/high/medium demand — so the fertilizer plan below prioritises closing those deficits. Sweet Corn prefers loam soils, while Nyeri 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 Nyeri's 69/100 suitability a realistic target here is closer to 6,900 kg/acre (~KES 276,000/acre) unless the constraints above are addressed.
