Growing Mint in Mombasa
Soil suitability analysis based on Mombasa's nutrient profile
Mombasa County is a challenging environment for Mint (soil-match score 1/100) and will need significant amendment before planting. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 6–7.5 band Mint 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/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. Mint prefers loam soils, while Mombasa is largely sandy, so drainage and organic-matter management matter more here. At 50 m, the county sits below Mint's preferred altitude range (500–2200 m), which limits yield potential due to heat stress. Mint's full potential is about 4,000 kg/acre (~KES 400,000/acre at KES 100/kg), but at Mombasa's 1/100 suitability a realistic target here is closer to 50 kg/acre (~KES 5,000/acre) unless the constraints above are addressed.
