Growing Carrot in Mandera
Soil suitability analysis based on Mandera's nutrient profile
Generally not ideal — Mandera is poorly suited to Carrot. Mandera's soil (pH 8.38, alkaline) gives Carrot a suitability score of 0/100. Match fertilizer to Mandera's nitrogen and phosphorus levels for the best result.
Mandera County is a challenging environment for Carrot (soil-match score 0/100) and will need significant amendment before planting. At an average pH of 8.38 the soil sits above Carrot's preferred 5.5–7 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.53 g/kg), phosphorus (38.3 mg/kg) and potassium (420 mg/kg) all meet Carrot's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy soils suit Carrot, which favours sandy loam. Mandera receives approximately 180 mm/year — well below Carrot's minimum of 600 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Carrot is the #85 soil match of the 106 crops we assess for Mandera County. Carrot's full potential is about 10,000 kg/acre (~KES 380,000/acre at KES 38/kg), but at Mandera'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 Mandera's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

| pH | 8.38 | 5.5–7 | Adjust |
| Nitrogen | 0.53 g/kg | min 0.5 g/kg | OK |
| Phosphorus | 38.3 mg/kg | min 12 mg/kg | OK |
| Potassium | 420 mg/kg | min 200 mg/kg | OK |

| Altitude | 250 m | 1,000–2,500 m | Low |
Top dressing guide
Mandera's nitrogen (0.53 g/kg) already meets Carrot's 0.5 g/kg requirement, so this is a maintenance rate.
