Growing Leek 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 Leek. Taita Taveta's soil (pH 6.64, near-neutral) gives Leek a suitability score of 45/100. Match fertilizer to Taita Taveta's nitrogen and phosphorus levels for the best result.

Leek can be grown in Taita Taveta County, but the soil scores 45/100 and needs targeted management to reach full potential. Local soils average pH 6.64 — neutral and inside the 6–7.5 band Leek 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/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly loam soils suit Leek, which favours loam. On ShambaIQ's soil-match model, Leek is the #57 soil match of the 106 crops we assess for Taita Taveta County. Leek's full potential is about 10,000 kg/acre (~KES 600,000/acre at KES 60/kg), but at Taita Taveta's 45/100 suitability a realistic target here is closer to 5,625 kg/acre (~KES 337,500/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.
