Growing Oilseed Rape (Canola) in Taita Taveta
Soil suitability analysis based on Taita Taveta's nutrient profile
Generally not ideal — Taita Taveta is poorly suited to Oilseed Rape (Canola). Taita Taveta's soil (pH 6.64, near-neutral) gives Oilseed Rape (Canola) a suitability score of 18/100. Match fertilizer to Taita Taveta's nitrogen and phosphorus levels for the best result.
Taita Taveta County is a challenging environment for Oilseed Rape (Canola) (soil-match score 18/100) and will need significant amendment before planting. Local soils average pH 6.64 — neutral and inside the 5.8–7.5 band Oilseed Rape (Canola) prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.97 g/kg, P 12.9 mg/kg, K 104 mg/kg against this crop's high/high/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly loam soils suit Oilseed Rape (Canola), which favours loam. At 700 m, the county sits below Oilseed Rape (Canola)'s preferred altitude range (1500–2800 m), which limits yield potential due to heat stress. On ShambaIQ's soil-match model, Oilseed Rape (Canola) is the #79 soil match of the 106 crops we assess for Taita Taveta County. Oilseed Rape (Canola)'s full potential is about 1,000 kg/acre (~KES 60,000/acre at KES 60/kg), but at Taita Taveta's 18/100 suitability a realistic target here is closer to 225 kg/acre (~KES 13,500/acre) unless the constraints above are addressed.
Better matched to Taita Taveta's soil: Sorghum, Cowpeas, and Pigeon Peas — each scores higher on the same soil.
