Growing Tomato in Lamu

Soil suitability analysis based on Lamu's nutrient profile

Quick answer

Yes, with the right inputs — Lamu is moderately suited to Tomato. Lamu's soil (pH 6.31, slightly acidic) gives Tomato a suitability score of 72/100. Match fertilizer to Lamu's nitrogen and phosphorus levels for the best result.

Lamu County is a solid choice for Tomato, with a soil-match score of 72/100. Local soils average pH 6.31 — slightly acidic to near-neutral and inside the 6–7 band Tomato prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.74 g/kg, P 9.6 mg/kg, K 117 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Tomato prefers loam soils, while Lamu is largely sandy, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Tomato is the #46 soil match of the 106 crops we assess for Lamu County. At current prices (about KES 50/kg) and a typical 15,000 kg/acre yield, a well-managed Tomato crop here can gross roughly KES 750,000 per acre.
