Growing Mint in Taita Taveta

Soil suitability analysis based on Taita Taveta's nutrient profile

Quick answer

Possible but challenging — Taita Taveta is only marginally suited to Mint. Taita Taveta's soil (pH 6.64, near-neutral) gives Mint a suitability score of 44/100. Match fertilizer to Taita Taveta's nitrogen and phosphorus levels for the best result.

Taita Taveta County is a challenging environment for Mint (soil-match score 44/100) and will need significant amendment before planting. Local soils average pH 6.64 — neutral and inside the 6–7.5 band Mint prefers, so no lime is usually required. The main gap is nitrogen and potassium — measured at N 0.97 g/kg, P 12.9 mg/kg, K 104 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly loam soils suit Mint, which favours loam. Taita Taveta receives approximately 500 mm/year — well below Mint's minimum of 700 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Mint is the #59 soil match of the 106 crops we assess for Taita Taveta County. Mint's full potential is about 4,000 kg/acre (~KES 400,000/acre at KES 100/kg), but at Taita Taveta's 44/100 suitability a realistic target here is closer to 2,200 kg/acre (~KES 220,000/acre) unless the constraints above are addressed.

Better matched to Taita Taveta's soil: Sorghum, Cowpeas, and Pigeon Peas — each scores higher on the same soil.
