Growing Soybeans in Kisii

Soil suitability analysis based on Kisii's nutrient profile

Quick answer

Yes — Kisii is well suited to Soybeans. Kisii's soil (pH 5.21, strongly acidic) gives Soybeans a suitability score of 82/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Kisii County is well suited to Soybeans, scoring 82/100 on ShambaIQ's soil-match model. Local soils average pH 5.21 — moderately acidic and inside the 5–7 band Soybeans prefers, so no lime is usually required. Nitrogen (1.09 g/kg), phosphorus (13.1 mg/kg) and potassium (151 mg/kg) all meet Soybeans's requirements, so a maintenance fertilizer programme is enough. 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.
