Growing Soybeans in Mombasa

Soil suitability analysis based on Mombasa's nutrient profile

Mombasa County is well suited to Soybeans, scoring 86/100 on ShambaIQ's soil-match model. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 5–7 band Soybeans prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 0.95 g/kg, P 8.4 mg/kg, K 136 mg/kg against this crop's low/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. Soybeans prefers loam soils, while Mombasa is largely sandy, so drainage and organic-matter management matter more here. At current prices (about KES 75/kg) and a typical 550 kg/acre yield, a well-managed Soybeans crop here can gross roughly KES 41,250 per acre.
