Growing Tomato in Nyamira

Soil suitability analysis based on Nyamira's nutrient profile

Quick answer

Yes, with the right inputs — Nyamira is moderately suited to Tomato. Nyamira's soil (pH 5.58, slightly acidic) gives Tomato a suitability score of 61/100. Match fertilizer to Nyamira's nitrogen and phosphorus levels for the best result.

Nyamira County is a solid choice for Tomato, with a soil-match score of 61/100. At an average pH of 5.58 the soil is slightly acidic to near-neutral, below Tomato's preferred 6–7 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/high/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Tomato, which favours loam. Tomato's full potential is about 15,000 kg/acre (~KES 750,000/acre at KES 50/kg), but at Nyamira's 61/100 suitability a realistic target here is closer to 11,438 kg/acre (~KES 571,900/acre) unless the constraints above are addressed.
