Growing Moringa in Trans Nzoia

Soil suitability analysis based on Trans Nzoia's nutrient profile

Trans Nzoia County is a challenging environment for Moringa (soil-match score 42/100) and will need significant amendment before planting. At an average pH of 5.93 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 (1.68 g/kg), phosphorus (27.3 mg/kg) and potassium (213 mg/kg) all meet Moringa's requirements, so a maintenance fertilizer programme is enough. Moringa prefers sandy loam soils, while Trans Nzoia is largely clay loam, so drainage and organic-matter management matter more here. At 1900 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 Trans Nzoia's 42/100 suitability a realistic target here is closer to 2,100 kg/acre (~KES 210,000/acre) unless the constraints above are addressed.
