Growing Cauliflower in Busia

Soil suitability analysis based on Busia's nutrient profile

Quick answer

Yes, with the right inputs — Busia is moderately suited to Cauliflower. Busia's soil (pH 5.29, strongly acidic) gives Cauliflower a suitability score of 61/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Busia County is a solid choice for Cauliflower, with a soil-match score of 61/100. At an average pH of 5.29 the soil is moderately acidic, below Cauliflower'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 0.91 g/kg, P 16.6 mg/kg, K 175 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 Cauliflower, which favours loam. On ShambaIQ's soil-match model, Cauliflower is the #56 soil match of the 106 crops we assess for Busia County. Cauliflower's full potential is about 10,000 kg/acre (~KES 600,000/acre at KES 60/kg), but at Busia's 61/100 suitability a realistic target here is closer to 7,625 kg/acre (~KES 457,500/acre) unless the constraints above are addressed.

Bags per acre in Busia
0.750.5

Busia's nitrogen (0.91 g/kg) is 76% of the 1.2 g/kg Cauliflower needs, so the standard 0.5 bags/acre is raised to 0.75. Split it across two applications to limit leaching.
