Growing Moringa in Vihiga

Soil suitability analysis based on Vihiga's nutrient profile

Vihiga County is a challenging environment for Moringa (soil-match score 36/100) and will need significant amendment before planting. At an average pH of 5.62 the soil is slightly acidic to near-neutral, below Moringa's preferred 6–8 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.02 g/kg), phosphorus (14.8 mg/kg) and potassium (164 mg/kg) all meet Moringa's requirements, so a maintenance fertilizer programme is enough. Moringa prefers sandy loam soils, while Vihiga 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 Vihiga's 36/100 suitability a realistic target here is closer to 1,800 kg/acre (~KES 180,000/acre) unless the constraints above are addressed.
