Growing Tomato in Siaya

Soil suitability analysis based on Siaya's nutrient profile

Siaya County is a solid choice for Tomato, with a soil-match score of 64/100. At an average pH of 5.33 the soil is moderately acidic, below Tomato's preferred 6–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is phosphorus and potassium — measured at N 1.2 g/kg, P 12.1 mg/kg, K 134 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. At current prices (about KES 40/kg) and a typical 5,000 kg/acre yield, a well-managed Tomato crop here can gross roughly KES 200,000 per acre.
