Growing Potato in Nyeri
Soil suitability analysis based on Nyeri's nutrient profile
Yes — Nyeri is well suited to Potato. Nyeri's soil (pH 5.23, strongly acidic) gives Potato a suitability score of 84/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Nyeri County is well suited to Potato, scoring 84/100 on ShambaIQ's soil-match model. Local soils average pH 5.23 — moderately acidic and inside the 4.8–6.5 band Potato prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 1.09 g/kg, P 15.5 mg/kg, K 192 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Potato prefers sandy loam soils, while Nyeri is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Potato is the #7 soil match of the 106 crops we assess for Nyeri County. At current prices (about KES 38/kg) and a typical 8,000 kg/acre yield, a well-managed Potato crop here can gross roughly KES 304,000 per acre.
