Growing Pawpaw in Mombasa
Soil suitability analysis based on Mombasa's nutrient profile
Yes — Mombasa is well suited to Pawpaw. Mombasa's soil (pH 6.24, slightly acidic) gives Pawpaw a suitability score of 78/100. Match fertilizer to Mombasa's nitrogen and phosphorus levels for the best result.
Mombasa County is well suited to Pawpaw, scoring 78/100 on ShambaIQ's soil-match model. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 6–7.5 band Pawpaw prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.95 g/kg, P 8.4 mg/kg, K 136 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy soils suit Pawpaw, which favours sandy loam. On ShambaIQ's soil-match model, Pawpaw is the #35 soil match of the 106 crops we assess for Mombasa County. At current prices (about KES 28/kg) and a typical 12,000 kg/acre yield, a well-managed Pawpaw crop here can gross roughly KES 336,000 per acre.

Top dressing guide
Mombasa's nitrogen (0.95 g/kg) is 79% of the 1.2 g/kg Pawpaw needs, so the standard 0.5 bags/acre is raised to 0.75. Split it across two applications to limit leaching.
