Growing Capsicum in Lamu
Soil suitability analysis based on Lamu's nutrient profile
Yes, with the right inputs — Lamu is moderately suited to Capsicum. Lamu's soil (pH 6.31, slightly acidic) gives Capsicum a suitability score of 73/100. Match fertilizer to Lamu's nitrogen and phosphorus levels for the best result.
Lamu County is a solid choice for Capsicum, with a soil-match score of 73/100. Local soils average pH 6.31 — slightly acidic to near-neutral and inside the 5.5–7 band Capsicum prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.74 g/kg, P 9.6 mg/kg, K 117 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Capsicum prefers loam soils, while Lamu is largely sandy, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Capsicum is the #43 soil match of the 106 crops we assess for Lamu County. At current prices (about KES 90/kg) and a typical 6,000 kg/acre yield, a well-managed Capsicum crop here can gross roughly KES 540,000 per acre.

Top dressing guide
Lamu's nitrogen (0.74 g/kg) is 62% of the 1.2 g/kg Capsicum needs, so the standard 0.5 bags/acre is raised to 0.75. Split it across two applications to limit leaching.
