Growing Wheat in Nyeri
Soil suitability analysis based on Nyeri's nutrient profile
Possible but challenging — Nyeri is only marginally suited to Wheat. Nyeri's soil (pH 5.23, strongly acidic) gives Wheat a suitability score of 48/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Wheat can be grown in Nyeri County, but the soil scores 48/100 and needs targeted management to reach full potential. At an average pH of 5.23 the soil is moderately acidic, 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 1.09 g/kg, P 15.5 mg/kg, K 192 mg/kg against this crop's high/high/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay soils suit Wheat, which favours clay. On ShambaIQ's soil-match model, Wheat is the #84 soil match of the 106 crops we assess for Nyeri County. Wheat's full potential is about 2,000 kg/acre (~KES 100,000/acre at KES 50/kg), but at Nyeri's 48/100 suitability a realistic target here is closer to 1,200 kg/acre (~KES 60,000/acre) unless the constraints above are addressed.
Better matched to Nyeri's soil: Macadamia, Pineapple, and Avocado — each scores higher on the same soil.

Top dressing guide
Nyeri's nitrogen (1.09 g/kg) is 91% 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.
