Growing Garlic in Marsabit
Soil suitability analysis based on Marsabit's nutrient profile
Generally not ideal — Marsabit is poorly suited to Garlic. Marsabit's soil (pH 8.22, alkaline) gives Garlic a suitability score of 20/100. Match fertilizer to Marsabit's nitrogen and phosphorus levels for the best result.
Marsabit County is a challenging environment for Garlic (soil-match score 20/100) and will need significant amendment before planting. At an average pH of 8.22 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 0.52 g/kg, P 37.3 mg/kg, K 420 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. Marsabit receives approximately 300 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 #32 soil match of the 106 crops we assess for Marsabit County. Garlic's full potential is about 3,000 kg/acre (~KES 825,000/acre at KES 275/kg), but at Marsabit's 20/100 suitability a realistic target here is closer to 750 kg/acre (~KES 206,250/acre) unless the constraints above are addressed.
Better matched to Marsabit's soil: Sisal, Chia, and Aloe Vera — each scores higher on the same soil.

Top dressing guide
Marsabit's nitrogen (0.52 g/kg) is 43% 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.
