Growing Pyrethrum in Migori
Soil suitability analysis based on Migori's nutrient profile
Possible but challenging — Migori is only marginally suited to Pyrethrum. Migori's soil (pH 5.43, strongly acidic) gives Pyrethrum a suitability score of 44/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Migori County is a challenging environment for Pyrethrum (soil-match score 44/100) and will need significant amendment before planting. Local soils average pH 5.43 — moderately acidic and inside the 5–6.5 band Pyrethrum prefers, so no lime is usually required. The main gap is phosphorus — measured at N 1.2 g/kg, P 12.2 mg/kg, K 169 mg/kg against this crop's medium/high/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Pyrethrum, which favours loam. On ShambaIQ's soil-match model, Pyrethrum is the #88 soil match of the 106 crops we assess for Migori County. Pyrethrum's full potential is about 500 kg/acre (~KES 140,000/acre at KES 280/kg), but at Migori's 44/100 suitability a realistic target here is closer to 275 kg/acre (~KES 77,000/acre) unless the constraints above are addressed.
Better matched to Migori's soil: Cassava, Macadamia, and Pineapple — each scores higher on the same soil.

| Altitude | 1,300 m | 1,800–3,000 m | Low |
Top dressing guide
Migori's nitrogen (1.2 g/kg) already meets Pyrethrum's 0.8 g/kg requirement, so this is a maintenance rate.
