Growing Sweet Orange in Homa Bay

Soil suitability analysis based on Homa Bay's nutrient profile

Quick answer

Yes, with the right inputs — Homa Bay is moderately suited to Sweet Orange. Homa Bay's soil (pH 5.27, strongly acidic) gives Sweet Orange a suitability score of 59/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Sweet Orange can be grown in Homa Bay County, but the soil scores 59/100 and needs targeted management to reach full potential. At an average pH of 5.27 the soil is moderately acidic, 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 1.05 g/kg, P 13.8 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 #70 soil match of the 106 crops we assess for Homa Bay County. Sweet Orange's full potential is about 12,000 kg/acre (~KES 600,000/acre at KES 50/kg), but at Homa Bay's 59/100 suitability a realistic target here is closer to 8,850 kg/acre (~KES 442,500/acre) unless the constraints above are addressed.

Better matched to Homa Bay's soil: Macadamia, Avocado, and Pineapple — each scores higher on the same soil.
