Growing Wambugu Apples in Busia

Soil suitability analysis based on Busia's nutrient profile

Quick answer

Possible but challenging — Busia is only marginally suited to Wambugu Apples. Busia's soil (pH 5.29, strongly acidic) gives Wambugu Apples a suitability score of 53/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Wambugu Apples can be grown in Busia County, but the soil scores 53/100 and needs targeted management to reach full potential. Local soils average pH 5.29 — moderately acidic and inside the 5–7 band Wambugu Apples prefers, so no lime is usually required. The main gap is potassium — measured at N 0.91 g/kg, P 16.6 mg/kg, K 175 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Wambugu Apples, which favours loam. Wambugu Apples's full potential is about 4,000 kg/acre (~KES 300,000/acre at KES 75/kg), but at Busia's 53/100 suitability a realistic target here is closer to 2,650 kg/acre (~KES 198,750/acre) unless the constraints above are addressed.
