Growing Mint in Nyamira
Soil suitability analysis based on Nyamira's nutrient profile
Nyamira County is a solid choice for Mint, with a soil-match score of 63/100. At an average pH of 5.58 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, phosphorus, and potassium — measured at N 0.84 g/kg, P 11.6 mg/kg, K 148 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Mint, which favours loam. Mint's full potential is about 4,000 kg/acre (~KES 400,000/acre at KES 100/kg), but at Nyamira's 63/100 suitability a realistic target here is closer to 3,150 kg/acre (~KES 315,000/acre) unless the constraints above are addressed.
