Growing Tomato in Kitui
Soil suitability analysis based on Kitui's nutrient profile
Yes, with the right inputs — Kitui is moderately suited to Tomato. Kitui's soil (pH 7.03, near-neutral) gives Tomato a suitability score of 55/100. Match fertilizer to Kitui's nitrogen and phosphorus levels for the best result.
Tomato can be grown in Kitui County, but the soil scores 55/100 and needs targeted management to reach full potential. At an average pH of 7.03 the soil sits above Tomato's preferred 6–7 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.74 g/kg, P 30.5 mg/kg, K 339 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Tomato, which favours loam. On ShambaIQ's soil-match model, Tomato is the #50 soil match of the 106 crops we assess for Kitui County. Tomato's full potential is about 15,000 kg/acre (~KES 750,000/acre at KES 50/kg), but at Kitui's 55/100 suitability a realistic target here is closer to 10,313 kg/acre (~KES 515,650/acre) unless the constraints above are addressed.
Better matched to Kitui's soil: Mango, Sisal, and Moringa — each scores higher on the same soil.
