Growing Cabbage in Kiambu

Soil suitability analysis based on Kiambu's nutrient profile

Kiambu County is a solid choice for Cabbage, with a soil-match score of 70/100. Local soils average pH 5.28 — moderately acidic 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 13.7 mg/kg, K 169 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay 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 Kiambu's 70/100 suitability a realistic target here is closer to 13,125 kg/acre (~KES 236,250/acre) unless the constraints above are addressed.
