Growing French Beans in Busia

Soil suitability analysis based on Busia's nutrient profile

Quick answer

Yes, with the right inputs — Busia is moderately suited to French Beans. Busia's soil (pH 5.29, strongly acidic) gives French Beans a suitability score of 73/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Busia County is a solid choice for French Beans, with a soil-match score of 73/100. At an average pH of 5.29 the soil is moderately acidic, below French Beans's preferred 5.8–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is phosphorus — measured at N 0.91 g/kg, P 16.6 mg/kg, K 175 mg/kg against this crop's low/high/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit French Beans, which favours loam. On ShambaIQ's soil-match model, French Beans is the #24 soil match of the 106 crops we assess for Busia County. At current prices (about KES 80/kg) and a typical 3,500 kg/acre yield, a well-managed French Beans crop here can gross roughly KES 280,000 per acre.
