Growing Wambugu Apples in Laikipia
Soil suitability analysis based on Laikipia's nutrient profile
Generally not ideal — Laikipia is poorly suited to Wambugu Apples. Laikipia's soil (pH 4.99, strongly acidic) gives Wambugu Apples a suitability score of 28/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Laikipia County is a challenging environment for Wambugu Apples (soil-match score 28/100) and will need significant amendment before planting. At an average pH of 4.99 the soil is strongly acidic, below Wambugu Apples's preferred 5–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.42 g/kg), phosphorus (16.6 mg/kg) and potassium (215 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. Laikipia receives approximately 600 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 #94 soil match of the 106 crops we assess for Laikipia County. Wambugu Apples's full potential is about 4,000 kg/acre (~KES 300,000/acre at KES 75/kg), but at Laikipia's 28/100 suitability a realistic target here is closer to 1,400 kg/acre (~KES 105,000/acre) unless the constraints above are addressed.
Better matched to Laikipia's soil: Sweet Potato, Finger Millet, and Groundnuts — each scores higher on the same soil.
