Growing Coffee (Robusta) in Kilifi
Soil suitability analysis based on Kilifi's nutrient profile
Generally not ideal — Kilifi is poorly suited to Coffee (Robusta). Kilifi's soil (pH 6.24, slightly acidic) gives Coffee (Robusta) a suitability score of 17/100. Match fertilizer to Kilifi's nitrogen and phosphorus levels for the best result.
Kilifi County is a challenging environment for Coffee (Robusta) (soil-match score 17/100) and will need significant amendment before planting. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 5–6.5 band Coffee (Robusta) prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.8 g/kg, P 11 mg/kg, K 109 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit Coffee (Robusta), which favours loam. Kilifi receives approximately 700 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 #63 soil match of the 106 crops we assess for Kilifi County. Coffee (Robusta)'s full potential is about 950 kg/acre (~KES 76,000/acre at KES 80/kg), but at Kilifi's 17/100 suitability a realistic target here is closer to 202 kg/acre (~KES 16,160/acre) unless the constraints above are addressed.
Better matched to Kilifi's soil: Sesame (Simsim), Sorghum, and Finger Millet — each scores higher on the same soil.

Top dressing guide
Kilifi's nitrogen (0.8 g/kg) is 67% of the 1.2 g/kg Coffee (Robusta) needs, so the standard 1 bag/acre is raised to 1.5. Split it across two applications to limit leaching.
