Growing Chia in Nairobi
Soil suitability analysis based on Nairobi's nutrient profile
Yes — Nairobi is well suited to Chia. Nairobi's soil (pH 6.85, near-neutral) gives Chia a suitability score of 88/100. Match fertilizer to Nairobi's nitrogen and phosphorus levels for the best result.
Nairobi County is well suited to Chia, scoring 88/100 on ShambaIQ's soil-match model. Local soils average pH 6.85 — neutral and inside the 6–8 band Chia prefers, so no lime is usually required. Nitrogen (1.1 g/kg), phosphorus (22.1 mg/kg) and potassium (236 mg/kg) all meet Chia's requirements, so a maintenance fertilizer programme is enough. Chia prefers sandy loam soils, while Nairobi is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Chia is the #45 soil match of the 106 crops we assess for Nairobi County. At current prices (about KES 150/kg) and a typical 400 kg/acre yield, a well-managed Chia crop here can gross roughly KES 60,000 per acre.

Top dressing guide
Nairobi's nitrogen (1.1 g/kg) already meets Chia's 0.5 g/kg requirement, so this is a maintenance rate.
