Growing Turmeric in Mombasa
Soil suitability analysis based on Mombasa's nutrient profile
Yes — Mombasa is well suited to Turmeric. Mombasa's soil (pH 6.24, slightly acidic) gives Turmeric a suitability score of 75/100. Match fertilizer to Mombasa's nitrogen and phosphorus levels for the best result.
Mombasa County is well suited to Turmeric, scoring 75/100 on ShambaIQ's soil-match model. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 5.5–7.5 band Turmeric prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.95 g/kg, P 8.4 mg/kg, K 136 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Turmeric prefers loam soils, while Mombasa is largely sandy, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Turmeric is the #44 soil match of the 106 crops we assess for Mombasa County. At current prices (about KES 80/kg) and a typical 6,000 kg/acre yield, a well-managed Turmeric crop here can gross roughly KES 480,000 per acre.

Top dressing guide
Mombasa's nitrogen (0.95 g/kg) is 79% of the 1.2 g/kg Turmeric needs, so the standard 0.5 bags/acre is raised to 0.75. Split it across two applications to limit leaching.
