Growing Grapes in Laikipia

Soil suitability analysis based on Laikipia's nutrient profile

Laikipia County is a solid choice for Grapes, with a soil-match score of 61/100. At an average pH of 4.99 the soil is strongly acidic, below Grapes's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is phosphorus — measured at N 1.42 g/kg, P 16.6 mg/kg, K 215 mg/kg against this crop's medium/high/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Grapes, which favours loam. Grapes's full potential is about 8,000 kg/acre (~KES 1,200,000/acre at KES 150/kg), but at Laikipia's 61/100 suitability a realistic target here is closer to 6,100 kg/acre (~KES 915,000/acre) unless the constraints above are addressed.
