Growing Potato in Kilifi
Soil suitability analysis based on Kilifi's nutrient profile
Generally not ideal — Kilifi is poorly suited to Potato. Kilifi's soil (pH 6.24, slightly acidic) gives Potato a suitability score of 1/100. Match fertilizer to Kilifi's nitrogen and phosphorus levels for the best result.
Kilifi County is a challenging environment for Potato (soil-match score 1/100) and will need significant amendment before planting. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 4.8–6.5 band Potato 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/high/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit Potato, which favours sandy loam. At 150 m, the county sits below Potato's preferred altitude range (1500–3000 m), which limits yield potential due to heat stress. On ShambaIQ's soil-match model, Potato is the #85 soil match of the 106 crops we assess for Kilifi County. Potato's full potential is about 8,000 kg/acre (~KES 304,000/acre at KES 38/kg), but at Kilifi's 1/100 suitability a realistic target here is closer to 100 kg/acre (~KES 3,800/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 Potato needs, so the standard 1 bag/acre is raised to 1.5. Split it across two applications to limit leaching.
