Growing Sweet Orange in Kakamega
Soil suitability analysis based on Kakamega's nutrient profile
Possible but challenging — Kakamega is only marginally suited to Sweet Orange. Kakamega's soil (pH 5.63, slightly acidic) gives Sweet Orange a suitability score of 47/100. Match fertilizer to Kakamega's nitrogen and phosphorus levels for the best result.
Sweet Orange can be grown in Kakamega County, but the soil scores 47/100 and needs targeted management to reach full potential. At an average pH of 5.63 the soil is slightly acidic to near-neutral, below Sweet Orange's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen, phosphorus, and potassium — measured at N 1.01 g/kg, P 14 mg/kg, K 147 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Sweet Orange, which favours loam. On ShambaIQ's soil-match model, Sweet Orange is the #69 soil match of the 106 crops we assess for Kakamega County. Sweet Orange's full potential is about 12,000 kg/acre (~KES 600,000/acre at KES 50/kg), but at Kakamega's 47/100 suitability a realistic target here is closer to 7,050 kg/acre (~KES 352,500/acre) unless the constraints above are addressed.
Better matched to Kakamega's soil: Soybeans, Rice (Lowland/Paddy), and Sweet Potato — each scores higher on the same soil.

Top dressing guide
Kakamega's nitrogen (1.01 g/kg) is 84% of the 1.2 g/kg Sweet Orange needs, so the standard 0.6 bags/acre is raised to 0.75. Split it across two applications to limit leaching.
