Growing Barley in Nyeri

Soil suitability analysis based on Nyeri's nutrient profile

Nyeri County is a challenging environment for Barley (soil-match score 42/100) and will need significant amendment before planting. At an average pH of 5.23 the soil is moderately acidic, 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 — measured at N 1.09 g/kg, P 15.5 mg/kg, K 192 mg/kg against this crop's medium/high/medium demand — so the fertilizer plan below prioritises closing that deficit. Barley prefers loam soils, while Nyeri is largely clay, so drainage and organic-matter management matter more here. 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.
