Growing Tomato in Kisumu

Soil suitability analysis based on Kisumu's nutrient profile

Kisumu County is a solid choice for Tomato, with a soil-match score of 68/100. At an average pH of 5.54 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 0.91 g/kg, P 12.5 mg/kg, K 166 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Tomato prefers loam soils, while Kisumu is largely clay, so drainage and organic-matter management matter more here. Tomato's full potential is about 15,000 kg/acre (~KES 750,000/acre at KES 50/kg), but at Kisumu's 68/100 suitability a realistic target here is closer to 12,750 kg/acre (~KES 637,500/acre) unless the constraints above are addressed.
