Growing Lemon in Mombasa

Soil suitability analysis based on Mombasa's nutrient profile

Mombasa County is a solid choice for Lemon, with a soil-match score of 72/100. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 6–7.5 band Lemon 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. Lemon prefers loam soils, while Mombasa is largely sandy, so drainage and organic-matter management matter more here. At current prices (about KES 50/kg) and a typical 10,000 kg/acre yield, a well-managed Lemon crop here can gross roughly KES 500,000 per acre.
