Growing Barley in Kwale

Soil suitability analysis based on Kwale's nutrient profile

Kwale County is a challenging environment for Barley (soil-match score 1/100) and will need significant amendment before planting. Local soils average pH 6.76 — neutral and inside the 6–7.5 band Barley prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 0.93 g/kg, P 9.8 mg/kg, K 131 mg/kg against this crop's medium/high/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit Barley, which favours loam. At 200 m, the county sits below Barley's preferred altitude range (2000–3000 m), which limits yield potential due to heat stress. 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.
