Growing Capsicum in Mombasa

Soil suitability analysis based on Mombasa's nutrient profile

Quick answer

Yes — Mombasa is well suited to Capsicum. Mombasa's soil (pH 6.24, slightly acidic) gives Capsicum a suitability score of 76/100. Match fertilizer to Mombasa's nitrogen and phosphorus levels for the best result.

Mombasa County is well suited to Capsicum, scoring 76/100 on ShambaIQ's soil-match model. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 5.5–7 band Capsicum 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. Capsicum prefers loam soils, while Mombasa is largely sandy, so drainage and organic-matter management matter more here. At current prices (about KES 90/kg) and a typical 6,000 kg/acre yield, a well-managed Capsicum crop here can gross roughly KES 540,000 per acre.
