Growing Tomato in Turkana
Soil suitability analysis based on Turkana's nutrient profile
Generally not ideal — Turkana is poorly suited to Tomato. Turkana's soil (pH 7.95, alkaline) gives Tomato a suitability score of 13/100. Match fertilizer to Turkana's nitrogen and phosphorus levels for the best result.
Turkana County is a challenging environment for Tomato (soil-match score 13/100) and will need significant amendment before planting. At an average pH of 7.95 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 0.41 g/kg, P 38.5 mg/kg, K 417 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing that deficit. Tomato prefers loam soils, while Turkana is largely sandy, so drainage and organic-matter management matter more here. Turkana receives approximately 300 mm/year — well below Tomato's minimum of 600 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Tomato is the #45 soil match of the 106 crops we assess for Turkana County. Tomato's full potential is about 15,000 kg/acre (~KES 750,000/acre at KES 50/kg), but at Turkana's 13/100 suitability a realistic target here is closer to 2,438 kg/acre (~KES 121,900/acre) unless the constraints above are addressed.
Better matched to Turkana's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

Top dressing guide
Turkana's nitrogen (0.41 g/kg) is 34% of the 1.2 g/kg Tomato needs, so the standard 0.5 bags/acre is raised to 0.75. Split it across two applications to limit leaching.
