Growing Garlic in Meru
Soil suitability analysis based on Meru's nutrient profile
Possible but challenging — Meru is only marginally suited to Garlic. Meru's soil (pH 4.88, strongly acidic) gives Garlic a suitability score of 44/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Meru County is a challenging environment for Garlic (soil-match score 44/100) and will need significant amendment before planting. At an average pH of 4.88 the soil is strongly acidic, below Garlic's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.22 g/kg), phosphorus (20.3 mg/kg) and potassium (218 mg/kg) all meet Garlic's requirements, so a maintenance fertilizer programme is enough. Garlic prefers sandy loam soils, while Meru 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 Meru's 44/100 suitability a realistic target here is closer to 1,650 kg/acre (~KES 453,750/acre) unless the constraints above are addressed.
