Growing Wheat in Vihiga
Soil suitability analysis based on Vihiga's nutrient profile
Generally not ideal — Vihiga is poorly suited to Wheat. Vihiga's soil (pH 5.62, slightly acidic) gives Wheat a suitability score of 34/100. Match fertilizer to Vihiga's nitrogen and phosphorus levels for the best result.
Vihiga County is a challenging environment for Wheat (soil-match score 34/100) and will need significant amendment before planting. At an average pH of 5.62 the soil is slightly acidic to near-neutral, below Wheat's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen and phosphorus — measured at N 1.02 g/kg, P 14.8 mg/kg, K 164 mg/kg against this crop's high/high/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Wheat, which favours clay. On ShambaIQ's soil-match model, Wheat is the #96 soil match of the 106 crops we assess for Vihiga County. Wheat's full potential is about 2,000 kg/acre (~KES 100,000/acre at KES 50/kg), but at Vihiga's 34/100 suitability a realistic target here is closer to 850 kg/acre (~KES 42,500/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.

Top dressing guide
Vihiga's nitrogen (1.02 g/kg) is 85% of the 1.2 g/kg Wheat needs, so the standard 1 bag/acre is raised to 1.25. Split it across two applications to limit leaching.
