Growing Cauliflower in Machakos

Soil suitability analysis based on Machakos's nutrient profile

Quick answer

Yes, with the right inputs — Machakos is moderately suited to Cauliflower. Machakos's soil (pH 7.03, near-neutral) gives Cauliflower a suitability score of 71/100. Match fertilizer to Machakos's nitrogen and phosphorus levels for the best result.

Machakos County is a solid choice for Cauliflower, with a soil-match score of 71/100. Local soils average pH 7.03 — neutral and inside the 6–7.5 band Cauliflower 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/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Cauliflower, which favours loam. On ShambaIQ's soil-match model, Cauliflower is the #70 soil match of the 106 crops we assess for Machakos County. Cauliflower's full potential is about 10,000 kg/acre (~KES 600,000/acre at KES 60/kg), but at Machakos's 71/100 suitability a realistic target here is closer to 8,875 kg/acre (~KES 532,500/acre) unless the constraints above are addressed.
