Growing Leek in Wajir
Soil suitability analysis based on Wajir's nutrient profile
Generally not ideal — Wajir is poorly suited to Leek. Wajir's soil (pH 8.4, alkaline) gives Leek a suitability score of 1/100. Match fertilizer to Wajir's nitrogen and phosphorus levels for the best result.
Wajir County is a challenging environment for Leek (soil-match score 1/100) and will need significant amendment before planting. At an average pH of 8.4 the soil sits above Leek'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 39.3 mg/kg, K 396 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Leek prefers loam soils, while Wajir is largely sandy, so drainage and organic-matter management matter more here. Wajir receives approximately 200 mm/year — well below Leek's minimum of 600 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Leek is the #77 soil match of the 106 crops we assess for Wajir County. Leek's full potential is about 10,000 kg/acre (~KES 600,000/acre at KES 60/kg), but at Wajir's 1/100 suitability a realistic target here is closer to 125 kg/acre (~KES 7,500/acre) unless the constraints above are addressed.
Better matched to Wajir's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

Top dressing guide
Wajir's nitrogen (0.52 g/kg) is 43% of the 1.2 g/kg Leek needs, so the standard 0.4 bags/acre is raised to 0.5. Split it across two applications to limit leaching.
