Growing Tomato in Siaya
Soil suitability analysis based on Siaya's nutrient profile
Yes, with the right inputs — Siaya is moderately suited to Tomato. Siaya's soil (pH 5.33, strongly acidic) gives Tomato a suitability score of 64/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
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. Tomato's full potential is about 15,000 kg/acre (~KES 750,000/acre at KES 50/kg), but at Siaya's 64/100 suitability a realistic target here is closer to 12,000 kg/acre (~KES 600,000/acre) unless the constraints above are addressed.
