Growing Carrot in Lamu

Soil suitability analysis based on Lamu's nutrient profile

Quick answer

Generally not ideal — Lamu is poorly suited to Carrot. Lamu's soil (pH 6.31, slightly acidic) gives Carrot a suitability score of 0/100. Match fertilizer to Lamu's nitrogen and phosphorus levels for the best result.

Lamu County is a challenging environment for Carrot (soil-match score 0/100) and will need significant amendment before planting. Local soils average pH 6.31 — slightly acidic to near-neutral and inside the 5.5–7 band Carrot prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 0.74 g/kg, P 9.6 mg/kg, K 117 mg/kg against this crop's low/medium/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy soils suit Carrot, which favours sandy loam. At 10 m, the county sits below Carrot's preferred altitude range (1000–2500 m), which limits yield potential due to heat stress. On ShambaIQ's soil-match model, Carrot is the #73 soil match of the 106 crops we assess for Lamu County. Carrot's full potential is about 10,000 kg/acre (~KES 380,000/acre at KES 38/kg), but at Lamu's 0/100 suitability a realistic target here is closer to 0 kg/acre (~KES 0/acre) unless the constraints above are addressed.

Better matched to Lamu's soil: Sesame (Simsim), Sorghum, and Cowpeas — each scores higher on the same soil.
