Growing Capsicum in Lamu

Soil suitability analysis based on Lamu's nutrient profile

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. At current prices (about KES 90/kg) and a typical 4,500 kg/acre yield, a well-managed Capsicum crop here can gross roughly KES 405,000 per acre.
