Growing Chia in Marsabit

Soil suitability analysis based on Marsabit's nutrient profile

Quick answer

Yes, with the right inputs — Marsabit is moderately suited to Chia. Marsabit's soil (pH 8.22, alkaline) gives Chia a suitability score of 69/100. Match fertilizer to Marsabit's nitrogen and phosphorus levels for the best result.

Marsabit County is a solid choice for Chia, with a soil-match score of 69/100. At an average pH of 8.22 the soil sits above Chia's preferred 6–8 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.52 g/kg), phosphorus (37.3 mg/kg) and potassium (420 mg/kg) all meet Chia's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy soils suit Chia, which favours sandy loam. On ShambaIQ's soil-match model, Chia is the #2 soil match of the 106 crops we assess for Marsabit County. Chia's full potential is about 400 kg/acre (~KES 60,000/acre at KES 150/kg), but at Marsabit's 69/100 suitability a realistic target here is closer to 345 kg/acre (~KES 51,750/acre) unless the constraints above are addressed.
