Growing Turmeric in Nairobi
Soil suitability analysis based on Nairobi's nutrient profile
Yes, with the right inputs — Nairobi is moderately suited to Turmeric. Nairobi's soil (pH 6.85, near-neutral) gives Turmeric a suitability score of 56/100. Match fertilizer to Nairobi's nitrogen and phosphorus levels for the best result.
Turmeric can be grown in Nairobi County, but the soil scores 56/100 and needs targeted management to reach full potential. Local soils average pH 6.85 — neutral and inside the 5.5–7.5 band Turmeric prefers, so no lime is usually required. The main gap is nitrogen — measured at N 1.1 g/kg, P 22.1 mg/kg, K 236 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Turmeric, which favours loam. On ShambaIQ's soil-match model, Turmeric is the #91 soil match of the 106 crops we assess for Nairobi County. Turmeric's full potential is about 6,000 kg/acre (~KES 480,000/acre at KES 80/kg), but at Nairobi's 56/100 suitability a realistic target here is closer to 4,200 kg/acre (~KES 336,000/acre) unless the constraints above are addressed.
Better matched to Nairobi's soil: Dhania, Pumpkin, and Rosemary — each scores higher on the same soil.

Top dressing guide
Nairobi's nitrogen (1.1 g/kg) is 92% of the 1.2 g/kg Turmeric needs, so the standard 0.5 bags/acre is raised to 0.75. Split it across two applications to limit leaching.
