Growing Barley in Meru
Soil suitability analysis based on Meru's nutrient profile
Generally not ideal — Meru is poorly suited to Barley. Meru's soil (pH 4.88, strongly acidic) gives Barley a suitability score of 28/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Meru County is a challenging environment for Barley (soil-match score 28/100) and will need significant amendment before planting. At an average pH of 4.88 the soil is strongly acidic, below Barley's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.22 g/kg), phosphorus (20.3 mg/kg) and potassium (218 mg/kg) all meet Barley's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Barley, which favours loam. On ShambaIQ's soil-match model, Barley is the #104 soil match of the 106 crops we assess for Meru County. Barley's full potential is about 1,600 kg/acre (~KES 67,200/acre at KES 42/kg), but at Meru's 28/100 suitability a realistic target here is closer to 560 kg/acre (~KES 23,520/acre) unless the constraints above are addressed.
Better matched to Meru's soil: Tea, Avocado, and Macadamia — each scores higher on the same soil.
