Growing Pumpkin in Mombasa

Soil suitability analysis based on Mombasa's nutrient profile

Quick answer

Yes — Mombasa is well suited to Pumpkin. Mombasa's soil (pH 6.24, slightly acidic) gives Pumpkin a suitability score of 82/100. Match fertilizer to Mombasa's nitrogen and phosphorus levels for the best result.

Mombasa County is well suited to Pumpkin, scoring 82/100 on ShambaIQ's soil-match model. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 5.8–7.5 band Pumpkin prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 0.95 g/kg, P 8.4 mg/kg, K 136 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy soils suit Pumpkin, which favours sandy loam. On ShambaIQ's soil-match model, Pumpkin is the #27 soil match of the 106 crops we assess for Mombasa County. At current prices (about KES 30/kg) and a typical 10,000 kg/acre yield, a well-managed Pumpkin crop here can gross roughly KES 300,000 per acre.
