Growing Lemon in Kisii

Soil suitability analysis based on Kisii's nutrient profile

Lemon can be grown in Kisii County, but the soil scores 58/100 and needs targeted management to reach full potential. At an average pH of 5.21 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 nitrogen, phosphorus, and potassium — measured at N 1.09 g/kg, P 13.1 mg/kg, K 151 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Lemon, which favours loam. Lemon's full potential is about 10,000 kg/acre (~KES 500,000/acre at KES 50/kg), but at Kisii's 58/100 suitability a realistic target here is closer to 7,250 kg/acre (~KES 362,500/acre) unless the constraints above are addressed.
