Growing Capsicum in Kitui
Soil suitability analysis based on Kitui's nutrient profile
Possible but challenging — Kitui is only marginally suited to Capsicum. Kitui's soil (pH 7.03, near-neutral) gives Capsicum a suitability score of 52/100. Match fertilizer to Kitui's nitrogen and phosphorus levels for the best result.
Capsicum can be grown in Kitui County, but the soil scores 52/100 and needs targeted management to reach full potential. At an average pH of 7.03 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 0.74 g/kg, P 30.5 mg/kg, K 339 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 Capsicum, which favours loam. On ShambaIQ's soil-match model, Capsicum is the #55 soil match of the 106 crops we assess for Kitui County. Capsicum's full potential is about 6,000 kg/acre (~KES 540,000/acre at KES 90/kg), but at Kitui's 52/100 suitability a realistic target here is closer to 3,900 kg/acre (~KES 351,000/acre) unless the constraints above are addressed.
Better matched to Kitui's soil: Mango, Sisal, and Moringa — each scores higher on the same soil.

| Altitude | 900 m | 0–2,000 m | OK |
Top dressing guide
Kitui's nitrogen (0.74 g/kg) is 62% 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.
