Kiambu County is well suited to Dolichos, scoring 76/100 on ShambaIQ's soil-match model. Local soils average pH 5.28 — moderately acidic and inside the 5–7.5 band Dolichos prefers, so no lime is usually required. Nitrogen (1.01 g/kg), phosphorus (13.7 mg/kg) and potassium (169 mg/kg) all meet Dolichos's requirements, so a maintenance fertilizer programme is enough. Dolichos prefers sandy loam soils, while Kiambu is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Dolichos is the #18 soil match of the 106 crops we assess for Kiambu County. At current prices (about KES 120/kg) and a typical 600 kg/acre yield, a well-managed Dolichos crop here can gross roughly KES 72,000 per acre.
