Growing Garlic in Samburu
Soil suitability analysis based on Samburu's nutrient profile
Generally not ideal — Samburu is poorly suited to Garlic. Samburu's soil (pH 8.28, alkaline) gives Garlic a suitability score of 27/100. Match fertilizer to Samburu's nitrogen and phosphorus levels for the best result.
Samburu County is a challenging environment for Garlic (soil-match score 27/100) and will need significant amendment before planting. At an average pH of 8.28 the soil sits above Garlic's preferred 6–7.5 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.67 g/kg, P 42.1 mg/kg, K 387 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy soils suit Garlic, which favours sandy loam. Samburu receives approximately 350 mm/year — well below Garlic's minimum of 500 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Garlic is the #29 soil match of the 106 crops we assess for Samburu County. Garlic's full potential is about 3,000 kg/acre (~KES 825,000/acre at KES 275/kg), but at Samburu's 27/100 suitability a realistic target here is closer to 1,013 kg/acre (~KES 278,575/acre) unless the constraints above are addressed.
Better matched to Samburu's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

Top dressing guide
Samburu's nitrogen (0.67 g/kg) is 56% of the 1.2 g/kg Garlic needs, so the standard 0.5 bags/acre is raised to 0.75. Split it across two applications to limit leaching.
