Growing Sorghum in Nyeri

Soil suitability analysis based on Nyeri's nutrient profile

Sorghum can be grown in Nyeri County, but the soil scores 47/100 and needs targeted management to reach full potential. Local soils average pH 5.23 — moderately acidic and inside the 5–8 band Sorghum prefers, so no lime is usually required. Nitrogen (1.09 g/kg), phosphorus (15.5 mg/kg) and potassium (192 mg/kg) all meet Sorghum's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay soils suit Sorghum, which favours clay. Sorghum's full potential is about 1,200 kg/acre (~KES 81,600/acre at KES 68/kg), but at Nyeri's 47/100 suitability a realistic target here is closer to 705 kg/acre (~KES 47,940/acre) unless the constraints above are addressed.
