Growing Garlic in Kakamega

Soil suitability analysis based on Kakamega's nutrient profile

Kakamega County is a challenging environment for Garlic (soil-match score 35/100) and will need significant amendment before planting. At an average pH of 5.63 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. The main gap is nitrogen and potassium — measured at N 1.01 g/kg, P 14 mg/kg, K 147 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 Kakamega 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 Kakamega's 35/100 suitability a realistic target here is closer to 1,313 kg/acre (~KES 361,075/acre) unless the constraints above are addressed.
