Growing Groundnuts in Kakamega

Soil suitability analysis based on Kakamega's nutrient profile

Kakamega County is a solid choice for Groundnuts, with a soil-match score of 74/100. Local soils average pH 5.63 — slightly acidic to near-neutral and inside the 5–7 band Groundnuts prefers, so no lime is usually required. The main gap is potassium — measured at N 1.01 g/kg, P 14 mg/kg, K 147 mg/kg against this crop's low/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Groundnuts prefers sandy soils, while Kakamega is largely clay loam, so drainage and organic-matter management matter more here. At current prices (about KES 90/kg) and a typical 500 kg/acre yield, a well-managed Groundnuts crop here can gross roughly KES 45,000 per acre.
