Growing Moringa in Vihiga
Soil suitability analysis based on Vihiga's nutrient profile
Generally not ideal — Vihiga is poorly suited to Moringa. Vihiga's soil (pH 5.62, slightly acidic) gives Moringa a suitability score of 36/100. Match fertilizer to Vihiga's nitrogen and phosphorus levels for the best result.
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. On ShambaIQ's soil-match model, Moringa is the #89 soil match of the 106 crops we assess for Vihiga County. 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.
Better matched to Vihiga's soil: Sweet Potato, Soybeans, and Coffee (Arabica) — each scores higher on the same soil.

Vihiga's nitrogen (1.02 g/kg) already meets Moringa's 0.5 g/kg requirement, so this is a maintenance rate.
