Growing Potato in Migori

Soil suitability analysis based on Migori's nutrient profile

Quick answer

Yes, with the right inputs — Migori is moderately suited to Potato. Migori's soil (pH 5.43, strongly acidic) gives Potato a suitability score of 63/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Migori County is a solid choice for Potato, with a soil-match score of 63/100. Local soils average pH 5.43 — moderately acidic and inside the 4.8–6.5 band Potato prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 1.2 g/kg, P 12.2 mg/kg, K 169 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 Migori is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Potato is the #56 soil match of the 106 crops we assess for Migori County. Potato's full potential is about 8,000 kg/acre (~KES 304,000/acre at KES 38/kg), but at Migori's 63/100 suitability a realistic target here is closer to 6,300 kg/acre (~KES 239,400/acre) unless the constraints above are addressed.
