Soil suitability analysis based on Nyamira's nutrient profile

Nyamira County is a challenging environment for Sesame (Simsim) (soil-match score 38/100) and will need significant amendment before planting. Local soils average pH 5.58 — slightly acidic to near-neutral and inside the 5.5–7 band Sesame (Simsim) prefers, so no lime is usually required.
