Growing Leek in Mombasa
Soil suitability analysis based on Mombasa's nutrient profile
Mombasa County is a challenging environment for Leek (soil-match score 0/100) 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 Leek 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/high demand — so the fertilizer plan below prioritises closing those deficits. Leek prefers loam soils, while Mombasa is largely sandy, so drainage and organic-matter management matter more here. At 50 m, the county sits below Leek's preferred altitude range (800–2500 m), which limits yield potential due to heat stress. Leek's full potential is about 10,000 kg/acre (~KES 600,000/acre at KES 60/kg), but at Mombasa's 0/100 suitability a realistic target here is closer to 0 kg/acre (~KES 0/acre) unless the constraints above are addressed.
