Soil suitability analysis based on Nairobi's nutrient profile

Quick answer

Yes — Nairobi is well suited to Oilseed Rape (Canola). Nairobi's soil (pH 6.85, near-neutral) gives Oilseed Rape (Canola) a suitability score of 90/100. Match fertilizer to Nairobi's nitrogen and phosphorus levels for the best result.

Nairobi County is well suited to Oilseed Rape (Canola), scoring 90/100 on ShambaIQ's soil-match model. Local soils average pH 6.85 — 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 1.1 g/kg, P 22.1 mg/kg, K 236 mg/kg against this crop's high/high/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Oilseed Rape (Canola), which favours loam. On ShambaIQ's soil-match model, Oilseed Rape (Canola) is the #27 soil match of the 106 crops we assess for Nairobi County. At current prices (about KES 60/kg) and a typical 1,000 kg/acre yield, a well-managed Oilseed Rape (Canola) crop here can gross roughly KES 60,000 per acre.
