Growing Banana in Makueni

Soil suitability analysis based on Makueni's nutrient profile

Makueni County is a challenging environment for Banana (soil-match score 15/100) and will need significant amendment before planting. At an average pH of 7.5 the soil sits above Banana's preferred 5–7 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.86 g/kg, P 29.6 mg/kg, K 351 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Banana, which favours loam. Makueni receives approximately 600 mm/year — well below Banana's minimum of 1200 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Banana is the #98 soil match of the 106 crops we assess for Makueni County. Banana's full potential is about 12,000 kg/acre (~KES 144,000/acre at KES 12/kg), but at Makueni's 15/100 suitability a realistic target here is closer to 2,250 kg/acre (~KES 27,000/acre) unless the constraints above are addressed.

Better matched to Makueni's soil: Lucerne, Mango, and Sisal — each scores higher on the same soil.
