Growing Chia in Kilifi
Soil suitability analysis based on Kilifi's nutrient profile
Generally not ideal — Kilifi is poorly suited to Chia. Kilifi's soil (pH 6.24, slightly acidic) gives Chia a suitability score of 2/100. Match fertilizer to Kilifi's nitrogen and phosphorus levels for the best result.
Kilifi County is a challenging environment for Chia (soil-match score 2/100) and will need significant amendment before planting. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 6–8 band Chia prefers, so no lime is usually required. The main gap is phosphorus — measured at N 0.8 g/kg, P 11 mg/kg, K 109 mg/kg against this crop's low/medium/low demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Chia, which favours sandy loam. At 150 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 #84 soil match of the 106 crops we assess for Kilifi County. Chia's full potential is about 400 kg/acre (~KES 60,000/acre at KES 150/kg), but at Kilifi's 2/100 suitability a realistic target here is closer to 10 kg/acre (~KES 1,500/acre) unless the constraints above are addressed.
Better matched to Kilifi's soil: Sesame (Simsim), Sorghum, and Finger Millet — each scores higher on the same soil.

Top dressing guide
Kilifi's nitrogen (0.8 g/kg) already meets Chia's 0.5 g/kg requirement, so this is a maintenance rate.
