Growing Oats in Kisumu

Soil suitability analysis based on Kisumu's nutrient profile

Quick answer

Generally not ideal — Kisumu is poorly suited to Oats. Kisumu's soil (pH 5.54, slightly acidic) gives Oats a suitability score of 31/100. Match fertilizer to Kisumu's nitrogen and phosphorus levels for the best result.

Kisumu County is a challenging environment for Oats (soil-match score 31/100) and will need significant amendment before planting. Local soils average pH 5.54 — slightly acidic to near-neutral and inside the 5.5–7 band Oats prefers, so no lime is usually required. Nitrogen (0.91 g/kg), phosphorus (12.5 mg/kg) and potassium (166 mg/kg) all meet Oats's requirements, so a maintenance fertilizer programme is enough. Oats prefers loam soils, while Kisumu is largely clay, so drainage and organic-matter management matter more here. At 1150 m, the county sits below Oats's preferred altitude range (1800–3000 m), which limits yield potential due to heat stress. On ShambaIQ's soil-match model, Oats is the #99 soil match of the 106 crops we assess for Kisumu County. Oats's full potential is about 1,600 kg/acre (~KES 64,000/acre at KES 40/kg), but at Kisumu's 31/100 suitability a realistic target here is closer to 620 kg/acre (~KES 24,800/acre) unless the constraints above are addressed.

Better matched to Kisumu's soil: Cassava, Macadamia, and Pineapple — each scores higher on the same soil.
