Growing Barley in Machakos
Soil suitability analysis based on Machakos's nutrient profile
Generally not ideal — Machakos is poorly suited to Barley. Machakos's soil (pH 7.03, near-neutral) gives Barley a suitability score of 27/100. Match fertilizer to Machakos's nitrogen and phosphorus levels for the best result.
Machakos County is a challenging environment for Barley (soil-match score 27/100) and will need significant amendment before planting. Local soils average pH 7.03 — neutral and inside the 6–7.5 band Barley prefers, so no lime is usually required. Nitrogen (0.82 g/kg), phosphorus (31.4 mg/kg) and potassium (338 mg/kg) all meet Barley's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Barley, which favours loam. At 1100 m, the county sits below Barley's preferred altitude range (2000–3000 m), which limits yield potential due to heat stress. On ShambaIQ's soil-match model, Barley is the #95 soil match of the 106 crops we assess for Machakos County. Barley's full potential is about 1,600 kg/acre (~KES 67,200/acre at KES 42/kg), but at Machakos's 27/100 suitability a realistic target here is closer to 540 kg/acre (~KES 22,680/acre) unless the constraints above are addressed.
Better matched to Machakos's soil: Mango, Sisal, and Moringa — each scores higher on the same soil.
