Growing Capsicum in Garissa

Soil suitability analysis based on Garissa's nutrient profile

Garissa County is a challenging environment for Capsicum (soil-match score 9/100) and will need significant amendment before planting. At an average pH of 7.96 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 0.61 g/kg, P 37.7 mg/kg, K 407 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing that deficit. Capsicum prefers loam soils, while Garissa is largely sandy, so drainage and organic-matter management matter more here. Garissa receives approximately 250 mm/year — well below Capsicum's minimum of 600 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 90/kg) and a typical 4,500 kg/acre yield, a well-managed Capsicum crop here can gross roughly KES 405,000 per acre.
