Growing Chia in Makueni
Soil suitability analysis based on Makueni's nutrient profile
Makueni County is well suited to Chia, scoring 86/100 on ShambaIQ's soil-match model. Local soils average pH 7.5 — alkaline and inside the 6–8 band Chia prefers, so no lime is usually required. Nitrogen (0.86 g/kg), phosphorus (29.6 mg/kg) and potassium (351 mg/kg) all meet Chia's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Chia, which favours sandy loam. 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.
