Growing Banana in Kisii

Soil suitability analysis based on Kisii's nutrient profile

Quick answer

Yes, with the right inputs — Kisii is moderately suited to Banana. Kisii's soil (pH 5.21, strongly acidic) gives Banana a suitability score of 61/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Kisii County is a solid choice for Banana, with a soil-match score of 61/100. Local soils average pH 5.21 — moderately acidic and inside the 5–7 band Banana prefers, so no lime is usually required. The main gap is nitrogen and potassium — measured at N 1.09 g/kg, P 13.1 mg/kg, K 151 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Banana, which favours loam. On ShambaIQ's soil-match model, Banana is the #42 soil match of the 106 crops we assess for Kisii County. Banana's full potential is about 12,000 kg/acre (~KES 144,000/acre at KES 12/kg), but at Kisii's 61/100 suitability a realistic target here is closer to 9,150 kg/acre (~KES 109,800/acre) unless the constraints above are addressed.
