Growing Tomato in Tana River

Soil suitability analysis based on Tana River's nutrient profile

Tana River County is a challenging environment for Tomato (soil-match score 33/100) and will need significant amendment before planting. Local soils average pH 6.4 — 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 1.04 g/kg, P 8.5 mg/kg, K 108 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Tomato prefers loam soils, while Tana River is largely sandy, so drainage and organic-matter management matter more here. Tana River receives approximately 400 mm/year — well below Tomato's minimum of 600 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 40/kg) and a typical 5,000 kg/acre yield, a well-managed Tomato crop here can gross roughly KES 200,000 per acre.
