Growing Grapes in Trans Nzoia

Soil suitability analysis based on Trans Nzoia's nutrient profile

Trans Nzoia County is a solid choice for Grapes, with a soil-match score of 67/100. At an average pH of 5.93 the soil is slightly acidic to near-neutral, below Grapes's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.68 g/kg), phosphorus (27.3 mg/kg) and potassium (213 mg/kg) all meet Grapes's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay 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 Trans Nzoia's 67/100 suitability a realistic target here is closer to 6,700 kg/acre (~KES 1,005,000/acre) unless the constraints above are addressed.
