Growing Tangerine in Meru

Soil suitability analysis based on Meru's nutrient profile

Tangerine 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 Tangerine'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 Tangerine's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Tangerine, which favours loam. Tangerine's full potential is about 10,000 kg/acre (~KES 600,000/acre at KES 60/kg), but at Meru's 55/100 suitability a realistic target here is closer to 6,875 kg/acre (~KES 412,500/acre) unless the constraints above are addressed.
