Growing Cabbage in Siaya
Soil suitability analysis based on Siaya's nutrient profile
Yes, with the right inputs — Siaya is moderately suited to Cabbage. Siaya's soil (pH 5.33, strongly acidic) gives Cabbage a suitability score of 70/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Siaya County is a solid choice for Cabbage, with a soil-match score of 70/100. Local soils average pH 5.33 — moderately acidic and inside the 5–7.5 band Cabbage prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 1.2 g/kg, P 12.1 mg/kg, K 134 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 #37 soil match of the 106 crops we assess for Siaya County. Cabbage's full potential is about 15,000 kg/acre (~KES 270,000/acre at KES 18/kg), but at Siaya'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.
