Growing Broccoli in Machakos
Soil suitability analysis based on Machakos's nutrient profile
Generally not ideal — Machakos is poorly suited to Broccoli. Machakos's soil (pH 7.03, near-neutral) gives Broccoli a suitability score of 24/100. Match fertilizer to Machakos's nitrogen and phosphorus levels for the best result.
Machakos County is a challenging environment for Broccoli (soil-match score 24/100) and will need significant amendment before planting. Local soils average pH 7.03 — neutral and inside the 6–7.5 band Broccoli 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 Broccoli, which favours loam. At 1100 m, the county sits below Broccoli's preferred altitude range (1800–2800 m), which limits yield potential due to heat stress. On ShambaIQ's soil-match model, Broccoli is the #98 soil match of the 106 crops we assess for Machakos County. Broccoli's full potential is about 6,000 kg/acre (~KES 540,000/acre at KES 90/kg), but at Machakos's 24/100 suitability a realistic target here is closer to 1,800 kg/acre (~KES 162,000/acre) unless the constraints above are addressed.
Better matched to Machakos's soil: Mango, Sisal, and Moringa — each scores higher on the same soil.

Top dressing guide
Machakos's nitrogen (0.82 g/kg) is 68% of the 1.2 g/kg Broccoli needs, so the standard 1.5 bags/acre is raised to 2.25. Split it across two applications to limit leaching.
