Growing Capsicum in Mandera
Soil suitability analysis based on Mandera's nutrient profile
Generally not ideal — Mandera is poorly suited to Capsicum. Mandera's soil (pH 8.38, alkaline) gives Capsicum a suitability score of 4/100. Match fertilizer to Mandera's nitrogen and phosphorus levels for the best result.
Mandera County is a challenging environment for Capsicum (soil-match score 4/100) and will need significant amendment before planting. At an average pH of 8.38 the soil sits above Capsicum's preferred 5.5–7 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.53 g/kg, P 38.3 mg/kg, K 420 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing that deficit. Capsicum prefers loam soils, while Mandera is largely sandy, so drainage and organic-matter management matter more here. Mandera receives approximately 180 mm/year — well below Capsicum's minimum of 600 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Capsicum is the #41 soil match of the 106 crops we assess for Mandera County. Capsicum's full potential is about 6,000 kg/acre (~KES 540,000/acre at KES 90/kg), but at Mandera's 4/100 suitability a realistic target here is closer to 300 kg/acre (~KES 27,000/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.

Top dressing guide
Mandera's nitrogen (0.53 g/kg) is 44% of the 1.2 g/kg Capsicum needs, so the standard 0.5 bags/acre is raised to 0.75. Split it across two applications to limit leaching.
