Growing Broccoli in Laikipia
Soil suitability analysis based on Laikipia's nutrient profile
Generally not ideal — Laikipia is poorly suited to Broccoli. Laikipia's soil (pH 4.99, strongly acidic) gives Broccoli a suitability score of 30/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Laikipia County is a challenging environment for Broccoli (soil-match score 30/100) and will need significant amendment before planting. At an average pH of 4.99 the soil is strongly 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 phosphorus — measured at N 1.42 g/kg, P 16.6 mg/kg, K 215 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. On ShambaIQ's soil-match model, Broccoli is the #92 soil match of the 106 crops we assess for Laikipia County. Broccoli's full potential is about 6,000 kg/acre (~KES 540,000/acre at KES 90/kg), but at Laikipia's 30/100 suitability a realistic target here is closer to 2,250 kg/acre (~KES 202,500/acre) unless the constraints above are addressed.
Better matched to Laikipia's soil: Sweet Potato, Finger Millet, and Groundnuts — each scores higher on the same soil.
