Growing Tomato in Wajir
Soil suitability analysis based on Wajir's nutrient profile
Generally not ideal — Wajir is poorly suited to Tomato. Wajir's soil (pH 8.4, alkaline) gives Tomato a suitability score of 5/100. Match fertilizer to Wajir's nitrogen and phosphorus levels for the best result.
Wajir County is a challenging environment for Tomato (soil-match score 5/100) and will need significant amendment before planting. At an average pH of 8.4 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 0.52 g/kg, P 39.3 mg/kg, K 396 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing that deficit. Tomato prefers loam soils, while Wajir is largely sandy, so drainage and organic-matter management matter more here. Wajir receives approximately 200 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 #40 soil match of the 106 crops we assess for Wajir County. Tomato's full potential is about 15,000 kg/acre (~KES 750,000/acre at KES 50/kg), but at Wajir's 5/100 suitability a realistic target here is closer to 938 kg/acre (~KES 46,900/acre) unless the constraints above are addressed.
Better matched to Wajir's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

Top dressing guide
Wajir's nitrogen (0.52 g/kg) is 43% 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.
