Growing Potato in Siaya

Soil suitability analysis based on Siaya's nutrient profile

Potato can be grown in Siaya County, but the soil scores 52/100 and needs targeted management to reach full potential. Local soils average pH 5.33 — 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 12.1 mg/kg, K 134 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 Siaya is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Potato is the #78 soil match of the 106 crops we assess for Siaya County. Potato's full potential is about 8,000 kg/acre (~KES 304,000/acre at KES 38/kg), but at Siaya's 52/100 suitability a realistic target here is closer to 5,200 kg/acre (~KES 197,600/acre) unless the constraints above are addressed.

Better matched to Siaya's soil: Macadamia, Pineapple, and Avocado — each scores higher on the same soil.
