Growing Cabbage in Kisii

Soil suitability analysis based on Kisii's nutrient profile

Quick answer

Yes, with the right inputs — Kisii is moderately suited to Cabbage. Kisii's soil (pH 5.21, strongly acidic) gives Cabbage a suitability score of 68/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Kisii County is a solid choice for Cabbage, with a soil-match score of 68/100. Local soils average pH 5.21 — 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 1.09 g/kg, P 13.1 mg/kg, K 151 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. On ShambaIQ's soil-match model, Cabbage is the #29 soil match of the 106 crops we assess for Kisii County. Cabbage's full potential is about 15,000 kg/acre (~KES 270,000/acre at KES 18/kg), but at Kisii's 68/100 suitability a realistic target here is closer to 12,750 kg/acre (~KES 229,500/acre) unless the constraints above are addressed.
