Growing Sweet Orange in Meru
Soil suitability analysis based on Meru's nutrient profile
Yes, with the right inputs — Meru is moderately suited to Sweet Orange. Meru's soil (pH 4.88, strongly acidic) gives Sweet Orange a suitability score of 55/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Sweet Orange can be grown in Meru County, but the soil scores 55/100 and needs targeted management to reach full potential. At an average pH of 4.88 the soil is strongly acidic, below Sweet Orange'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 Sweet Orange's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Sweet Orange, which favours loam. On ShambaIQ's soil-match model, Sweet Orange is the #67 soil match of the 106 crops we assess for Meru County. Sweet Orange's full potential is about 12,000 kg/acre (~KES 600,000/acre at KES 50/kg), but at Meru's 55/100 suitability a realistic target here is closer to 8,250 kg/acre (~KES 412,500/acre) unless the constraints above are addressed.
Better matched to Meru's soil: Tea, Avocado, and Macadamia — each scores higher on the same soil.
