Growing Pixie Oranges in Kirinyaga

Soil suitability analysis based on Kirinyaga's nutrient profile

Kirinyaga County is a solid choice for Pixie Oranges, with a soil-match score of 69/100. At an average pH of 5.31 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 1.36 g/kg, P 12.5 mg/kg, K 177 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 Kirinyaga is largely clay, so drainage and organic-matter management matter more here. At current prices (about KES 28/kg) and a typical 4,000 kg/acre yield, a well-managed Pixie Oranges crop here can gross roughly KES 112,000 per acre.
