Growing Coffee (Robusta) in West Pokot
Soil suitability analysis based on West Pokot's nutrient profile
Generally not ideal — West Pokot is poorly suited to Coffee (Robusta). West Pokot's soil (pH 6.04, slightly acidic) gives Coffee (Robusta) a suitability score of 26/100. Match fertilizer to West Pokot's nitrogen and phosphorus levels for the best result.
West Pokot County is a challenging environment for Coffee (Robusta) (soil-match score 26/100) and will need significant amendment before planting. Local soils average pH 6.04 — slightly acidic to near-neutral and inside the 5–6.5 band Coffee (Robusta) prefers, so no lime is usually required. Nitrogen (1.67 g/kg), phosphorus (24.8 mg/kg) and potassium (211 mg/kg) all meet Coffee (Robusta)'s requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Coffee (Robusta), which favours loam. West Pokot receives approximately 1000 mm/year — well below Coffee (Robusta)'s minimum of 1500 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Coffee (Robusta) is the #104 soil match of the 106 crops we assess for West Pokot County. Coffee (Robusta)'s full potential is about 950 kg/acre (~KES 76,000/acre at KES 80/kg), but at West Pokot's 26/100 suitability a realistic target here is closer to 309 kg/acre (~KES 24,720/acre) unless the constraints above are addressed.
Better matched to West Pokot's soil: Kale (Sukuma Wiki), Finger Millet, and Groundnuts — each scores higher on the same soil.
