Growing Lemongrass in Kisii

Soil suitability analysis based on Kisii's nutrient profile

Kisii County is a solid choice for Lemongrass, with a soil-match score of 71/100. At an average pH of 5.21 the soil is moderately acidic, below Lemongrass's preferred 5.5–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.09 g/kg), phosphorus (13.1 mg/kg) and potassium (151 mg/kg) all meet Lemongrass's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Lemongrass, which favours loam. Lemongrass's full potential is about 8,000 kg/acre (~KES 480,000/acre at KES 60/kg), but at Kisii's 71/100 suitability a realistic target here is closer to 7,100 kg/acre (~KES 426,000/acre) unless the constraints above are addressed.
