Growing Groundnuts in Kisii

Soil suitability analysis based on Kisii's nutrient profile

Quick answer

Yes — Kisii is well suited to Groundnuts. Kisii's soil (pH 5.21, strongly acidic) gives Groundnuts a suitability score of 79/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Kisii County is well suited to Groundnuts, scoring 79/100 on ShambaIQ's soil-match model. Local soils average pH 5.21 — moderately acidic and inside the 5–7 band Groundnuts prefers, so no lime is usually required. Nitrogen (1.09 g/kg), phosphorus (13.1 mg/kg) and potassium (151 mg/kg) all meet Groundnuts's requirements, so a maintenance fertilizer programme is enough. Groundnuts prefers sandy soils, while Kisii is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Groundnuts is the #15 soil match of the 106 crops we assess for Kisii County. At current prices (about KES 90/kg) and a typical 500 kg/acre yield, a well-managed Groundnuts crop here can gross roughly KES 45,000 per acre.
