Growing Lemon in Murang'a

Soil suitability analysis based on Murang'a's nutrient profile

Lemon can be grown in Murang'a County, but the soil scores 55/100 and needs targeted management to reach full potential. At an average pH of 5.03 the soil is moderately acidic, below Lemon's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is phosphorus and potassium — measured at N 1.2 g/kg, P 12.2 mg/kg, K 168 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Lemon prefers loam soils, while Murang'a is largely clay, so drainage and organic-matter management matter more here. Lemon's full potential is about 10,000 kg/acre (~KES 500,000/acre at KES 50/kg), but at Murang'a's 55/100 suitability a realistic target here is closer to 6,875 kg/acre (~KES 343,750/acre) unless the constraints above are addressed.
