Growing Beans in Lamu

Soil suitability analysis based on Lamu's nutrient profile

Lamu County is well suited to Beans, scoring 89/100 on ShambaIQ's soil-match model. Local soils average pH 6.31 — slightly acidic to near-neutral and inside the 6–7 band Beans prefers, so no lime is usually required. The main gap is phosphorus — measured at N 0.74 g/kg, P 9.6 mg/kg, K 117 mg/kg against this crop's low/medium/low demand — so the fertilizer plan below prioritises closing that deficit. Beans prefers loam soils, while Lamu is largely sandy, so drainage and organic-matter management matter more here. At current prices (about KES 120/kg) and a typical 700 kg/acre yield, a well-managed Beans crop here can gross roughly KES 84,000 per acre.
