Growing Wambugu Apples in Kajiado

Soil suitability analysis based on Kajiado's nutrient profile

Quick answer

Generally not ideal — Kajiado is poorly suited to Wambugu Apples. Kajiado's soil (pH 6.55, near-neutral) gives Wambugu Apples a suitability score of 16/100. Match fertilizer to Kajiado's nitrogen and phosphorus levels for the best result.

Kajiado County is a challenging environment for Wambugu Apples (soil-match score 16/100) and will need significant amendment before planting. Local soils average pH 6.55 — neutral and inside the 5–7 band Wambugu Apples prefers, so no lime is usually required. Nitrogen (0.97 g/kg), phosphorus (20.6 mg/kg) and potassium (257 mg/kg) all meet Wambugu Apples's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Wambugu Apples, which favours loam. Kajiado 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 Kajiado's 16/100 suitability a realistic target here is closer to 800 kg/acre (~KES 60,000/acre) unless the constraints above are addressed.
