Growing Oats in Kwale
Soil suitability analysis based on Kwale's nutrient profile
Generally not ideal — Kwale is poorly suited to Oats. Kwale's soil (pH 6.76, near-neutral) gives Oats a suitability score of 1/100. Match fertilizer to Kwale's nitrogen and phosphorus levels for the best result.
Kwale County is a challenging environment for Oats (soil-match score 1/100) and will need significant amendment before planting. Local soils average pH 6.76 — neutral and inside the 5.5–7 band Oats prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 0.93 g/kg, P 9.8 mg/kg, K 131 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit Oats, which favours loam. At 200 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 #103 soil match of the 106 crops we assess for Kwale County. Oats's full potential is about 1,600 kg/acre (~KES 64,000/acre at KES 40/kg), but at Kwale's 1/100 suitability a realistic target here is closer to 20 kg/acre (~KES 800/acre) unless the constraints above are addressed.
Better matched to Kwale's soil: Dhania, Pigeon Peas, and Mango — each scores higher on the same soil.

Kwale's nitrogen (0.93 g/kg) already meets Oats's 0.8 g/kg requirement, so this is a maintenance rate.
