Siaya County is well suited to Soybeans, scoring 84/100 on ShambaIQ's soil-match model. Local soils average pH 5.33 — moderately acidic and inside the 5–7 band Soybeans prefers, so no lime is usually required. The main gap is potassium — measured at N 1.2 g/kg, P 12.1 mg/kg, K 134 mg/kg against this crop's low/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Soybeans, which favours loam. At current prices (about KES 75/kg) and a typical 700 kg/acre yield, a well-managed Soybeans crop here can gross roughly KES 52,500 per acre.
