Growing Grapes in Murang'a

Soil suitability analysis based on Murang'a's nutrient profile

Grapes can be grown in Murang'a County, but the soil scores 51/100 and needs targeted management to reach full potential. At an average pH of 5.03 the soil is moderately acidic, 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 1.2 g/kg, P 12.2 mg/kg, K 168 mg/kg against this crop's medium/high/high demand — so the fertilizer plan below prioritises closing those deficits. Grapes prefers loam soils, while Murang'a is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Grapes is the #79 soil match of the 106 crops we assess for Murang'a County. Grapes's full potential is about 8,000 kg/acre (~KES 1,200,000/acre at KES 150/kg), but at Murang'a's 51/100 suitability a realistic target here is closer to 5,100 kg/acre (~KES 765,000/acre) unless the constraints above are addressed.

Better matched to Murang'a's soil: Tea, Macadamia, and Pineapple — each scores higher on the same soil.
