Growing Barley in Kakamega

Soil suitability analysis based on Kakamega's nutrient profile

Quick answer

Generally not ideal — Kakamega is poorly suited to Barley. Kakamega's soil (pH 5.63, slightly acidic) gives Barley a suitability score of 22/100. Match fertilizer to Kakamega's nitrogen and phosphorus levels for the best result.

Kakamega County is a challenging environment for Barley (soil-match score 22/100) and will need significant amendment before planting. At an average pH of 5.63 the soil is slightly acidic to near-neutral, below Barley'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 1.01 g/kg, P 14 mg/kg, K 147 mg/kg against this crop's medium/high/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Barley, which favours loam. On ShambaIQ's soil-match model, Barley is the #104 soil match of the 106 crops we assess for Kakamega County. Barley's full potential is about 1,600 kg/acre (~KES 67,200/acre at KES 42/kg), but at Kakamega's 22/100 suitability a realistic target here is closer to 440 kg/acre (~KES 18,480/acre) unless the constraints above are addressed.

Better matched to Kakamega's soil: Soybeans, Rice (Lowland/Paddy), and Sweet Potato — each scores higher on the same soil.
