Growing Grapes in Kisumu

Soil suitability analysis based on Kisumu's nutrient profile

Grapes can be grown in Kisumu County, but the soil scores 59/100 and needs targeted management to reach full potential. At an average pH of 5.54 the soil is slightly acidic to near-neutral, below Grapes's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is phosphorus and potassium — measured at N 0.91 g/kg, P 12.5 mg/kg, K 166 mg/kg against this crop's medium/high/high demand — so the fertilizer plan below prioritises closing those deficits. Grapes prefers loam soils, while Kisumu is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Grapes is the #72 soil match of the 106 crops we assess for Kisumu County. Grapes's full potential is about 8,000 kg/acre (~KES 1,200,000/acre at KES 150/kg), but at Kisumu's 59/100 suitability a realistic target here is closer to 5,900 kg/acre (~KES 885,000/acre) unless the constraints above are addressed.

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