Growing Coffee (Robusta) in Nandi
Soil suitability analysis based on Nandi's nutrient profile
Generally not ideal — Nandi is poorly suited to Coffee (Robusta). Nandi's soil (pH 6.17, slightly acidic) gives Coffee (Robusta) a suitability score of 31/100. Match fertilizer to Nandi's nitrogen and phosphorus levels for the best result.
Nandi County is a challenging environment for Coffee (Robusta) (soil-match score 31/100) and will need significant amendment before planting. Local soils average pH 6.17 — slightly acidic to near-neutral and inside the 5–6.5 band Coffee (Robusta) prefers, so no lime is usually required. Nitrogen (1.37 g/kg), phosphorus (26.4 mg/kg) and potassium (207 mg/kg) all meet Coffee (Robusta)'s requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Coffee (Robusta), which favours loam. At 1900 m, the county sits above Coffee (Robusta)'s preferred altitude ceiling of 1200 m, where frost risk and cold nights reduce the crop's productivity. On ShambaIQ's soil-match model, Coffee (Robusta) is the #102 soil match of the 106 crops we assess for Nandi County. Coffee (Robusta)'s full potential is about 950 kg/acre (~KES 76,000/acre at KES 80/kg), but at Nandi's 31/100 suitability a realistic target here is closer to 368 kg/acre (~KES 29,440/acre) unless the constraints above are addressed.
Better matched to Nandi's soil: Garden Peas, Maize, and Kale (Sukuma Wiki) — each scores higher on the same soil.
