Growing Garlic in Busia

Soil suitability analysis based on Busia's nutrient profile

Garlic can be grown in Busia County, but the soil scores 46/100 and needs targeted management to reach full potential. At an average pH of 5.29 the soil is moderately acidic, below Garlic's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen and potassium — measured at N 0.91 g/kg, P 16.6 mg/kg, K 175 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing those deficits. Garlic prefers sandy loam soils, while Busia 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 Busia's 46/100 suitability a realistic target here is closer to 1,725 kg/acre (~KES 474,375/acre) unless the constraints above are addressed.
