Kisumu County is a solid choice for Sesame (Simsim), with a soil-match score of 64/100. Local soils average pH 5.54 — slightly acidic to near-neutral and inside the 5.5–7 band Sesame (Simsim) prefers, so no lime is usually required. Nitrogen (0.91 g/kg), phosphorus (12.5 mg/kg) and potassium (166 mg/kg) all meet Sesame (Simsim)'s requirements, so a maintenance fertilizer programme is enough. Sesame (Simsim) prefers sandy soils, while Kisumu is largely clay, so drainage and organic-matter management matter more here.
