Growing Mint in Kisumu

Soil suitability analysis based on Kisumu's nutrient profile

Kisumu County is a solid choice for Mint, with a soil-match score of 69/100. At an average pH of 5.54 the soil is slightly acidic to near-neutral, below Mint's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen — measured at N 0.91 g/kg, P 12.5 mg/kg, K 166 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Mint prefers loam soils, while Kisumu is largely clay, so drainage and organic-matter management matter more here. Mint's full potential is about 4,000 kg/acre (~KES 400,000/acre at KES 100/kg), but at Kisumu's 69/100 suitability a realistic target here is closer to 3,450 kg/acre (~KES 345,000/acre) unless the constraints above are addressed.
