Growing Pixie Oranges in Murang'a

Soil suitability analysis based on Murang'a's nutrient profile

Quick answer

Yes, with the right inputs — Murang'a is moderately suited to Pixie Oranges. Murang'a's soil (pH 5.03, strongly acidic) gives Pixie Oranges a suitability score of 66/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Murang'a County is a solid choice for Pixie Oranges, with a soil-match score of 66/100. At an average pH of 5.03 the soil is moderately acidic, below Pixie Oranges's preferred 5.5–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is potassium — measured at N 1.2 g/kg, P 12.2 mg/kg, K 168 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Pixie Oranges prefers sandy loam soils, while Murang'a is largely clay, so drainage and organic-matter management matter more here. Pixie Oranges's full potential is about 8,000 kg/acre (~KES 224,000/acre at KES 28/kg), but at Murang'a's 66/100 suitability a realistic target here is closer to 6,600 kg/acre (~KES 184,800/acre) unless the constraints above are addressed.
