Growing Broccoli in Embu
Soil suitability analysis based on Embu's nutrient profile
Generally not ideal — Embu is poorly suited to Broccoli. Embu's soil (pH 5.1, strongly acidic) gives Broccoli a suitability score of 34/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Embu County is a challenging environment for Broccoli (soil-match score 34/100) and will need significant amendment before planting. At an average pH of 5.1 the soil is moderately acidic, below Broccoli's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen, phosphorus, and potassium — measured at N 1.04 g/kg, P 12.6 mg/kg, K 194 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Broccoli, which favours loam. On ShambaIQ's soil-match model, Broccoli is the #101 soil match of the 106 crops we assess for Embu County. Broccoli's full potential is about 6,000 kg/acre (~KES 540,000/acre at KES 90/kg), but at Embu's 34/100 suitability a realistic target here is closer to 2,550 kg/acre (~KES 229,500/acre) unless the constraints above are addressed.
Better matched to Embu's soil: Pineapple, Avocado, and Macadamia — each scores higher on the same soil.

Top dressing guide
Embu's nitrogen (1.04 g/kg) is 87% of the 1.2 g/kg Broccoli needs, so the standard 1.5 bags/acre is raised to 2. Split it across two applications to limit leaching.
