Growing Ginger in Kisii

Soil suitability analysis based on Kisii's nutrient profile

Ginger can be grown in Kisii County, but the soil scores 58/100 and needs targeted management to reach full potential. At an average pH of 5.21 the soil is moderately acidic, below Ginger's preferred 5.5–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is potassium — measured at N 1.09 g/kg, P 13.1 mg/kg, K 151 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Ginger prefers sandy loam soils, while Kisii is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Ginger is the #53 soil match of the 106 crops we assess for Kisii County. Ginger's full potential is about 6,000 kg/acre (~KES 1,200,000/acre at KES 200/kg), but at Kisii's 58/100 suitability a realistic target here is closer to 4,350 kg/acre (~KES 870,000/acre) unless the constraints above are addressed.

Better matched to Kisii's soil: Tea, Macadamia, and Pineapple — each scores higher on the same soil.
