Growing Wheat in Nyamira

Soil suitability analysis based on Nyamira's nutrient profile

Quick answer

Generally not ideal — Nyamira is poorly suited to Wheat. Nyamira's soil (pH 5.58, slightly acidic) gives Wheat a suitability score of 36/100. Match fertilizer to Nyamira's nitrogen and phosphorus levels for the best result.

Nyamira County is a challenging environment for Wheat (soil-match score 36/100) and will need significant amendment before planting. At an average pH of 5.58 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, phosphorus, and potassium — measured at N 0.84 g/kg, P 11.6 mg/kg, K 148 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 #92 soil match of the 106 crops we assess for Nyamira County. Wheat's full potential is about 2,000 kg/acre (~KES 100,000/acre at KES 50/kg), but at Nyamira's 36/100 suitability a realistic target here is closer to 900 kg/acre (~KES 45,000/acre) unless the constraints above are addressed.

Better matched to Nyamira's soil: Sweet Potato, Soybeans, and Pineapple — each scores higher on the same soil.
