Growing Moringa in Nyandarua

Soil suitability analysis based on Nyandarua's nutrient profile

Nyandarua County is a challenging environment for Moringa (soil-match score 24/100) and will need significant amendment before planting. At an average pH of 5.38 the soil is moderately acidic, below Moringa's preferred 6–8 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.28 g/kg), phosphorus (14 mg/kg) and potassium (166 mg/kg) all meet Moringa's requirements, so a maintenance fertilizer programme is enough. Moringa prefers sandy loam soils, while Nyandarua is largely clay, so drainage and organic-matter management matter more here. At 2300 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 Nyandarua's 24/100 suitability a realistic target here is closer to 1,200 kg/acre (~KES 120,000/acre) unless the constraints above are addressed.
