Growing Oats in Homa Bay

Soil suitability analysis based on Homa Bay's nutrient profile

Homa Bay County is a challenging environment for Oats (soil-match score 33/100) and will need significant amendment before planting. At an average pH of 5.27 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. The main gap is potassium — measured at N 1.05 g/kg, P 13.8 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. At 1200 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 Homa Bay County. Oats's full potential is about 1,600 kg/acre (~KES 64,000/acre at KES 40/kg), but at Homa Bay'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 Homa Bay's soil: Macadamia, Avocado, and Pineapple — each scores higher on the same soil.
