Growing Broccoli in Trans Nzoia

Soil suitability analysis based on Trans Nzoia's nutrient profile

Trans Nzoia County is well suited to Broccoli, scoring 82/100 on ShambaIQ's soil-match model. At an average pH of 5.93 the soil is slightly acidic to near-neutral, below Broccoli's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.68 g/kg), phosphorus (27.3 mg/kg) and potassium (213 mg/kg) all meet Broccoli's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Broccoli, which favours loam. At current prices (about KES 90/kg) and a typical 5,000 kg/acre yield, a well-managed Broccoli crop here can gross roughly KES 450,000 per acre.
