Growing Wheat in Kisii
Soil suitability analysis based on Kisii's nutrient profile
Generally not ideal — Kisii is poorly suited to Wheat. Kisii's soil (pH 5.21, strongly acidic) gives Wheat a suitability score of 37/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Kisii County is a challenging environment for Wheat (soil-match score 37/100) and will need significant amendment before planting. At an average pH of 5.21 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 13.1 mg/kg, K 151 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 #86 soil match of the 106 crops we assess for Kisii County. Wheat's full potential is about 2,000 kg/acre (~KES 100,000/acre at KES 50/kg), but at Kisii's 37/100 suitability a realistic target here is closer to 925 kg/acre (~KES 46,250/acre) unless the constraints above are addressed.
Better matched to Kisii's soil: Tea, Macadamia, and Pineapple — each scores higher on the same soil.

Top dressing guide
Kisii'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.
