Growing Chia in Turkana
Soil suitability analysis based on Turkana's nutrient profile
Generally not ideal — Turkana is poorly suited to Chia. Turkana's soil (pH 7.95, alkaline) gives Chia a suitability score of 11/100. Match fertilizer to Turkana's nitrogen and phosphorus levels for the best result.
Turkana County is a challenging environment for Chia (soil-match score 11/100) and will need significant amendment before planting. Local soils average pH 7.95 — alkaline and inside the 6–8 band Chia prefers, so no lime is usually required. The main gap is nitrogen — measured at N 0.41 g/kg, P 38.5 mg/kg, K 417 mg/kg against this crop's low/medium/low demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy soils suit Chia, which favours sandy loam. At 400 m, the county sits below Chia's preferred altitude range (1000–2200 m), which limits yield potential due to heat stress. On ShambaIQ's soil-match model, Chia is the #51 soil match of the 106 crops we assess for Turkana County. Chia's full potential is about 400 kg/acre (~KES 60,000/acre at KES 150/kg), but at Turkana's 11/100 suitability a realistic target here is closer to 55 kg/acre (~KES 8,250/acre) unless the constraints above are addressed.
Better matched to Turkana's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

Top dressing guide
Turkana's nitrogen (0.41 g/kg) is 82% of the 0.5 g/kg Chia needs, so the standard 0.2 bags/acre is raised to 0.25. Split it across two applications to limit leaching.
