Growing Cabbage in Tharaka Nithi
Soil suitability analysis based on Tharaka Nithi's nutrient profile
Yes, with the right inputs — Tharaka Nithi is moderately suited to Cabbage. Tharaka Nithi's soil (pH 4.99, strongly acidic) gives Cabbage a suitability score of 70/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Tharaka Nithi County is a solid choice for Cabbage, with a soil-match score of 70/100. At an average pH of 4.99 the soil is strongly acidic, below Cabbage's preferred 5–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is phosphorus — measured at N 1.23 g/kg, P 19.6 mg/kg, K 211 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing that deficit. Cabbage prefers clay loam soils, while Tharaka Nithi is largely sandy loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Cabbage is the #17 soil match of the 106 crops we assess for Tharaka Nithi County. Cabbage's full potential is about 15,000 kg/acre (~KES 270,000/acre at KES 18/kg), but at Tharaka Nithi'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.
