Growing Oats in Kakamega

Soil suitability analysis based on Kakamega's nutrient profile

Quick answer

Generally not ideal — Kakamega is poorly suited to Oats. Kakamega's soil (pH 5.63, slightly acidic) gives Oats a suitability score of 33/100. Match fertilizer to Kakamega's nitrogen and phosphorus levels for the best result.

Kakamega County is a challenging environment for Oats (soil-match score 33/100) and will need significant amendment before planting. Local soils average pH 5.63 — slightly acidic to near-neutral and inside the 5.5–7 band Oats prefers, so no lime is usually required. The main gap is potassium — measured at N 1.01 g/kg, P 14 mg/kg, K 147 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Oats, which favours loam. On ShambaIQ's soil-match model, Oats is the #99 soil match of the 106 crops we assess for Kakamega County. Oats's full potential is about 1,600 kg/acre (~KES 64,000/acre at KES 40/kg), but at Kakamega's 33/100 suitability a realistic target here is closer to 660 kg/acre (~KES 26,400/acre) unless the constraints above are addressed.

Better matched to Kakamega's soil: Soybeans, Rice (Lowland/Paddy), and Sweet Potato — each scores higher on the same soil.
