Growing Oilseed Rape (Canola) in Machakos
Soil suitability analysis based on Machakos's nutrient profile
Possible but challenging — Machakos is only marginally suited to Oilseed Rape (Canola). Machakos's soil (pH 7.03, near-neutral) gives Oilseed Rape (Canola) a suitability score of 45/100. Match fertilizer to Machakos's nitrogen and phosphorus levels for the best result.
Oilseed Rape (Canola) can be grown in Machakos County, but the soil scores 45/100 and needs targeted management to reach full potential. Local soils average pH 7.03 — neutral and inside the 5.8–7.5 band Oilseed Rape (Canola) prefers, so no lime is usually required. The main gap is nitrogen — measured at N 0.82 g/kg, P 31.4 mg/kg, K 338 mg/kg against this crop's high/high/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Oilseed Rape (Canola), which favours loam. On ShambaIQ's soil-match model, Oilseed Rape (Canola) is the #80 soil match of the 106 crops we assess for Machakos County. Oilseed Rape (Canola)'s full potential is about 1,000 kg/acre (~KES 60,000/acre at KES 60/kg), but at Machakos's 45/100 suitability a realistic target here is closer to 563 kg/acre (~KES 33,780/acre) unless the constraints above are addressed.
Better matched to Machakos's soil: Mango, Sisal, and Moringa — each scores higher on the same soil.
