Growing Sweet Corn in Mombasa
Soil suitability analysis based on Mombasa's nutrient profile
Yes — Mombasa is well suited to Sweet Corn. Mombasa's soil (pH 6.24, slightly acidic) gives Sweet Corn a suitability score of 77/100. Match fertilizer to Mombasa's nitrogen and phosphorus levels for the best result.
Mombasa County is well suited to Sweet Corn, scoring 77/100 on ShambaIQ's soil-match model. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 5.8–7 band Sweet Corn 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/high/medium demand — so the fertilizer plan below prioritises closing those deficits. Sweet Corn prefers loam soils, while Mombasa is largely sandy, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Sweet Corn is the #39 soil match of the 106 crops we assess for Mombasa County. At current prices (about KES 40/kg) and a typical 8,000 kg/acre yield, a well-managed Sweet Corn crop here can gross roughly KES 320,000 per acre.

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