Growing Cabbage in Kakamega

Soil suitability analysis based on Kakamega's nutrient profile

Kakamega County is a solid choice for Cabbage, with a soil-match score of 67/100. Local soils average pH 5.63 — slightly acidic to near-neutral and inside the 5–7.5 band Cabbage prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 1.01 g/kg, P 14 mg/kg, K 147 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Cabbage, which favours clay loam. Cabbage's full potential is about 15,000 kg/acre (~KES 270,000/acre at KES 18/kg), but at Kakamega's 67/100 suitability a realistic target here is closer to 12,563 kg/acre (~KES 226,134/acre) unless the constraints above are addressed.
