Growing Wambugu Apples in Taita Taveta

Soil suitability analysis based on Taita Taveta's nutrient profile

Quick answer

Generally not ideal — Taita Taveta is poorly suited to Wambugu Apples. Taita Taveta's soil (pH 6.64, near-neutral) gives Wambugu Apples a suitability score of 4/100. Match fertilizer to Taita Taveta's nitrogen and phosphorus levels for the best result.

Taita Taveta County is a challenging environment for Wambugu Apples (soil-match score 4/100) and will need significant amendment before planting. Local soils average pH 6.64 — neutral and inside the 5–7 band Wambugu Apples prefers, so no lime is usually required. The main gap is potassium — measured at N 0.97 g/kg, P 12.9 mg/kg, K 104 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly loam soils suit Wambugu Apples, which favours loam. Taita Taveta receives approximately 500 mm/year — well below Wambugu Apples's minimum of 1000 mm — so supplemental irrigation would be essential for this crop. Wambugu Apples's full potential is about 4,000 kg/acre (~KES 300,000/acre at KES 75/kg), but at Taita Taveta's 4/100 suitability a realistic target here is closer to 200 kg/acre (~KES 15,000/acre) unless the constraints above are addressed.
