Growing Pyrethrum in West Pokot

Soil suitability analysis based on West Pokot's nutrient profile

West Pokot County is a solid choice for Pyrethrum, with a soil-match score of 64/100. Local soils average pH 6.04 — slightly acidic to near-neutral and inside the 5–6.5 band Pyrethrum prefers, so no lime is usually required. Nitrogen (1.67 g/kg), phosphorus (24.8 mg/kg) and potassium (211 mg/kg) all meet Pyrethrum's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Pyrethrum, which favours loam. Pyrethrum's full potential is about 500 kg/acre (~KES 140,000/acre at KES 280/kg), but at West Pokot's 64/100 suitability a realistic target here is closer to 400 kg/acre (~KES 112,000/acre) unless the constraints above are addressed.
