Growing Barley in Nyamira

Soil suitability analysis based on Nyamira's nutrient profile

Nyamira County is a challenging environment for Barley (soil-match score 33/100) and will need significant amendment before planting. At an average pH of 5.58 the soil is slightly acidic to near-neutral, below Barley's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is phosphorus and potassium — measured at N 0.84 g/kg, P 11.6 mg/kg, K 148 mg/kg against this crop's medium/high/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Barley, which favours loam. 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.
