Growing Coffee (Arabica) in Kilifi
Soil suitability analysis based on Kilifi's nutrient profile
Generally not ideal — Kilifi is poorly suited to Coffee (Arabica). Kilifi's soil (pH 6.24, slightly acidic) gives Coffee (Arabica) a suitability score of 0/100. Match fertilizer to Kilifi's nitrogen and phosphorus levels for the best result.
Kilifi County is a challenging environment for Coffee (Arabica) (soil-match score 0/100) and will need significant amendment before planting. At an average pH of 6.24 the soil sits above Coffee (Arabica)'s preferred 5–6 range, which can limit uptake of phosphorus and micronutrients. 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 (Arabica), which favours loam. Kilifi receives approximately 700 mm/year — well below Coffee (Arabica)'s minimum of 1000 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Coffee (Arabica) is the #102 soil match of the 106 crops we assess for Kilifi County. Coffee (Arabica)'s full potential is about 800 kg/acre (~KES 96,000/acre at KES 120/kg), but at Kilifi's 0/100 suitability a realistic target here is closer to 0 kg/acre (~KES 0/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 (Arabica) needs, so the standard 1 bag/acre is raised to 1.5. Split it across two applications to limit leaching.
