Growing Oats in Kisumu

Soil suitability analysis based on Kisumu's nutrient profile

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. 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.
