Growing Garlic in Trans Nzoia
Soil suitability analysis based on Trans Nzoia's nutrient profile
Yes, with the right inputs — Trans Nzoia is moderately suited to Garlic. Trans Nzoia's soil (pH 5.93, slightly acidic) gives Garlic a suitability score of 69/100. Match fertilizer to Trans Nzoia's nitrogen and phosphorus levels for the best result.
Trans Nzoia County is a solid choice for Garlic, with a soil-match score of 69/100. At an average pH of 5.93 the soil is slightly acidic to near-neutral, below Garlic'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 Garlic's requirements, so a maintenance fertilizer programme is enough. Garlic prefers sandy loam soils, while Trans Nzoia is largely clay loam, so drainage and organic-matter management matter more here. Garlic's full potential is about 3,000 kg/acre (~KES 825,000/acre at KES 275/kg), but at Trans Nzoia's 69/100 suitability a realistic target here is closer to 2,588 kg/acre (~KES 711,700/acre) unless the constraints above are addressed.
