Growing Barley in Vihiga
Soil suitability analysis based on Vihiga's nutrient profile
Generally not ideal — Vihiga is poorly suited to Barley. Vihiga's soil (pH 5.62, slightly acidic) gives Barley a suitability score of 31/100. Match fertilizer to Vihiga's nitrogen and phosphorus levels for the best result.
Vihiga County is a challenging environment for Barley (soil-match score 31/100) and will need significant amendment before planting. At an average pH of 5.62 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 — measured at N 1.02 g/kg, P 14.8 mg/kg, K 164 mg/kg against this crop's medium/high/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Barley, which favours loam. On ShambaIQ's soil-match model, Barley is the #101 soil match of the 106 crops we assess for Vihiga County. Barley's full potential is about 1,600 kg/acre (~KES 67,200/acre at KES 42/kg), but at Vihiga's 31/100 suitability a realistic target here is closer to 620 kg/acre (~KES 26,040/acre) unless the constraints above are addressed.
Better matched to Vihiga's soil: Sweet Potato, Soybeans, and Coffee (Arabica) — each scores higher on the same soil.
