Growing Barley in Nyandarua

Soil suitability analysis based on Nyandarua's nutrient profile

Nyandarua County is a solid choice for Barley, with a soil-match score of 62/100. At an average pH of 5.38 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 1.28 g/kg, P 14 mg/kg, K 166 mg/kg against this crop's medium/high/medium demand — so the fertilizer plan below prioritises closing that deficit. Barley prefers loam soils, while Nyandarua 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.

Instruction
Apply CAN at early tillering, but keep nitrogen moderate — excess N raises grain protein and lowers malting quality
