Growing Wambugu Apples in Kitui
Soil suitability analysis based on Kitui's nutrient profile
Generally not ideal — Kitui is poorly suited to Wambugu Apples. Kitui's soil (pH 7.03, near-neutral) gives Wambugu Apples a suitability score of 7/100. Match fertilizer to Kitui's nitrogen and phosphorus levels for the best result.
Kitui County is a challenging environment for Wambugu Apples (soil-match score 7/100) and will need significant amendment before planting. At an average pH of 7.03 the soil sits above Wambugu Apples's preferred 5–7 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.74 g/kg, P 30.5 mg/kg, K 339 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Wambugu Apples, which favours loam. Kitui receives approximately 500 mm/year — well below Wambugu Apples's minimum of 1000 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Wambugu Apples is the #104 soil match of the 106 crops we assess for Kitui County. Wambugu Apples's full potential is about 4,000 kg/acre (~KES 300,000/acre at KES 75/kg), but at Kitui's 7/100 suitability a realistic target here is closer to 350 kg/acre (~KES 26,250/acre) unless the constraints above are addressed.
Better matched to Kitui's soil: Mango, Sisal, and Moringa — each scores higher on the same soil.

Top dressing guide
Kitui's nitrogen (0.74 g/kg) is 93% of the 0.8 g/kg Wambugu Apples needs, so the standard 0.5 bags/acre is raised to 0.75. Split it across two applications to limit leaching.
