Growing Moringa in Nairobi

Soil suitability analysis based on Nairobi's nutrient profile

Nairobi County is a solid choice for Moringa, with a soil-match score of 63/100. Local soils average pH 6.85 — neutral and inside the 6–8 band Moringa prefers, so no lime is usually required. Nitrogen (1.1 g/kg), phosphorus (22.1 mg/kg) and potassium (236 mg/kg) all meet Moringa's requirements, so a maintenance fertilizer programme is enough. Moringa prefers sandy loam soils, while Nairobi is largely clay loam, so drainage and organic-matter management matter more here. At 1700 m, the county sits above Moringa's preferred altitude ceiling of 1400 m, where frost risk and cold nights reduce the crop's productivity. Moringa's full potential is about 4,000 kg/acre (~KES 400,000/acre at KES 100/kg), but at Nairobi's 63/100 suitability a realistic target here is closer to 3,150 kg/acre (~KES 315,000/acre) unless the constraints above are addressed.
