Growing Oats in Wajir

Soil suitability analysis based on Wajir's nutrient profile

Wajir County is a challenging environment for Oats (soil-match score 0/100) and will need significant amendment before planting. At an average pH of 8.4 the soil sits above Oats's preferred 5.5–7 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.52 g/kg, P 39.3 mg/kg, K 396 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Oats prefers loam soils, while Wajir is largely sandy, so drainage and organic-matter management matter more here. Wajir receives approximately 200 mm/year — well below Oats's minimum of 500 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Oats is the #102 soil match of the 106 crops we assess for Wajir County. Oats's full potential is about 1,600 kg/acre (~KES 64,000/acre at KES 40/kg), but at Wajir's 0/100 suitability a realistic target here is closer to 0 kg/acre (~KES 0/acre) unless the constraints above are addressed.

Better matched to Wajir's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.
