Growing Oats in Machakos
Soil suitability analysis based on Machakos's nutrient profile
Generally not ideal — Machakos is poorly suited to Oats. Machakos's soil (pH 7.03, near-neutral) gives Oats a suitability score of 30/100. Match fertilizer to Machakos's nitrogen and phosphorus levels for the best result.
Machakos County is a challenging environment for Oats (soil-match score 30/100) and will need significant amendment before planting. At an average pH of 7.03 the soil sits above Oats's preferred 5.5–7 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.82 g/kg), phosphorus (31.4 mg/kg) and potassium (338 mg/kg) all meet Oats's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Oats, which favours loam. At 1100 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 #93 soil match of the 106 crops we assess for Machakos County. Oats's full potential is about 1,600 kg/acre (~KES 64,000/acre at KES 40/kg), but at Machakos's 30/100 suitability a realistic target here is closer to 600 kg/acre (~KES 24,000/acre) unless the constraints above are addressed.
Better matched to Machakos's soil: Mango, Sisal, and Moringa — each scores higher on the same soil.

Machakos's nitrogen (0.82 g/kg) already meets Oats's 0.8 g/kg requirement, so this is a maintenance rate.
