Growing Beetroot in Tharaka Nithi
Soil suitability analysis based on Tharaka Nithi's nutrient profile
Yes, with the right inputs — Tharaka Nithi is moderately suited to Beetroot. Tharaka Nithi's soil (pH 4.99, strongly acidic) gives Beetroot a suitability score of 61/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Tharaka Nithi County is a solid choice for Beetroot, with a soil-match score of 61/100. At an average pH of 4.99 the soil is strongly acidic, below Beetroot's preferred 6–7.5 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. The county's predominantly sandy loam soils suit Beetroot, which favours loam. On ShambaIQ's soil-match model, Beetroot is the #65 soil match of the 106 crops we assess for Tharaka Nithi County. Beetroot's full potential is about 10,000 kg/acre (~KES 500,000/acre at KES 50/kg), but at Tharaka Nithi's 61/100 suitability a realistic target here is closer to 7,625 kg/acre (~KES 381,250/acre) unless the constraints above are addressed.
