Growing Barley in Garissa

Soil suitability analysis based on Garissa's nutrient profile

Garissa County is a challenging environment for Barley (soil-match score 0/100) and will need significant amendment before planting. At an average pH of 7.96 the soil sits above Barley's preferred 6–7.5 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 medium/high/medium demand — so the fertilizer plan below prioritises closing that deficit. Barley 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 Barley's minimum of 500 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 42/kg) and a typical 1,100 kg/acre yield, a well-managed Barley crop here can gross roughly KES 46,200 per acre.
