Growing Lemon in Vihiga

Soil suitability analysis based on Vihiga's nutrient profile

Vihiga County is a solid choice for Lemon, with a soil-match score of 61/100. At an average pH of 5.62 the soil is slightly acidic to near-neutral, 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 1.02 g/kg, P 14.8 mg/kg, K 164 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 Vihiga's 61/100 suitability a realistic target here is closer to 7,625 kg/acre (~KES 381,250/acre) unless the constraints above are addressed.
