Growing Oilseed Rape (Canola) in Bomet

Soil suitability analysis based on Bomet's nutrient profile

Oilseed Rape (Canola) can be grown in Bomet County, but the soil scores 57/100 and needs targeted management to reach full potential. Local soils average pH 6.02 — slightly acidic to near-neutral and inside the 5.8–7.5 band Oilseed Rape (Canola) prefers, so no lime is usually required. Nitrogen (1.38 g/kg), phosphorus (23.6 mg/kg) and potassium (237 mg/kg) all meet Oilseed Rape (Canola)'s requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Oilseed Rape (Canola), which favours loam. Oilseed Rape (Canola)'s full potential is about 1,000 kg/acre (~KES 60,000/acre at KES 60/kg), but at Bomet's 57/100 suitability a realistic target here is closer to 713 kg/acre (~KES 42,780/acre) unless the constraints above are addressed.
