Growing Leek in Kilifi

Soil suitability analysis based on Kilifi's nutrient profile

Kilifi County is a challenging environment for Leek (soil-match score 3/100) 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 0.8 g/kg, P 11 mg/kg, K 109 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit Leek, which favours loam. At 150 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 Kilifi's 3/100 suitability a realistic target here is closer to 375 kg/acre (~KES 22,500/acre) unless the constraints above are addressed.
