Growing Oats in Kisii
Soil suitability analysis based on Kisii's nutrient profile
Possible but challenging — Kisii is only marginally suited to Oats. Kisii's soil (pH 5.21, strongly acidic) gives Oats a suitability score of 51/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Oats can be grown in Kisii County, but the soil scores 51/100 and needs targeted management to reach full potential. At an average pH of 5.21 the soil is moderately acidic, below Oats's preferred 5.5–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.09 g/kg), phosphorus (13.1 mg/kg) and potassium (151 mg/kg) all meet Oats's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Oats, which favours loam. On ShambaIQ's soil-match model, Oats is the #66 soil match of the 106 crops we assess for Kisii County. Oats's full potential is about 1,600 kg/acre (~KES 64,000/acre at KES 40/kg), but at Kisii's 51/100 suitability a realistic target here is closer to 1,020 kg/acre (~KES 40,800/acre) unless the constraints above are addressed.
Better matched to Kisii's soil: Tea, Macadamia, and Pineapple — each scores higher on the same soil.
