Growing Oilseed Rape (Canola) in Marsabit

Soil suitability analysis based on Marsabit's nutrient profile

Marsabit County is a challenging environment for Oilseed Rape (Canola) (soil-match score 16/100) and will need significant amendment before planting. At an average pH of 8.22 the soil sits above Oilseed Rape (Canola)'s preferred 5.8–7.5 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.52 g/kg, P 37.3 mg/kg, K 420 mg/kg against this crop's high/high/medium demand — so the fertilizer plan below prioritises closing that deficit. Oilseed Rape (Canola) prefers loam soils, while Marsabit is largely sandy, so drainage and organic-matter management matter more here. Oilseed Rape (Canola)'s full potential is about 1,000 kg/acre (~KES 60,000/acre at KES 60/kg), but at Marsabit's 16/100 suitability a realistic target here is closer to 200 kg/acre (~KES 12,000/acre) unless the constraints above are addressed.
