Nyeri County is a solid choice for Pigeon Peas, with a soil-match score of 61/100. Local soils average pH 5.23 — moderately acidic and inside the 5–8 band Pigeon Peas prefers, so no lime is usually required. Nitrogen (1.09 g/kg), phosphorus (15.5 mg/kg) and potassium (192 mg/kg) all meet Pigeon Peas's requirements, so a maintenance fertilizer programme is enough.
