Growing Turmeric in Kajiado

Soil suitability analysis based on Kajiado's nutrient profile

Kajiado County is a challenging environment for Turmeric (soil-match score 22/100) and will need significant amendment before planting. Local soils average pH 6.55 — 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 0.97 g/kg, P 20.6 mg/kg, K 257 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Turmeric, which favours loam. Kajiado receives approximately 500 mm/year — well below Turmeric's minimum of 1000 mm — so supplemental irrigation would be essential for this crop. Turmeric's full potential is about 6,000 kg/acre (~KES 480,000/acre at KES 80/kg), but at Kajiado's 22/100 suitability a realistic target here is closer to 1,650 kg/acre (~KES 132,000/acre) unless the constraints above are addressed.
