Growing Cowpeas in Nakuru
Soil suitability analysis based on Nakuru's nutrient profile
Nakuru County is well suited to Cowpeas, scoring 80/100 on ShambaIQ's soil-match model. Local soils average pH 6.28 — slightly acidic to near-neutral and inside the 5–8 band Cowpeas prefers, so no lime is usually required. Nitrogen (1.59 g/kg), phosphorus (25.2 mg/kg) and potassium (239 mg/kg) all meet Cowpeas's requirements, so a maintenance fertilizer programme is enough. Cowpeas prefers sandy soils, while Nakuru is largely clay loam, so drainage and organic-matter management matter more here. At current prices (about KES 65/kg) and a typical 350 kg/acre yield, a well-managed Cowpeas crop here can gross roughly KES 22,750 per acre.
