Growing Lemongrass in Nyeri

Soil suitability analysis based on Nyeri's nutrient profile

Nyeri County is a solid choice for Lemongrass, with a soil-match score of 72/100. At an average pH of 5.23 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 (15.5 mg/kg) and potassium (192 mg/kg) all meet Lemongrass's requirements, so a maintenance fertilizer programme is enough. Lemongrass prefers loam soils, while Nyeri is largely clay, so drainage and organic-matter management matter more here. At current prices (about KES 60/kg) and a typical 8,000 kg/acre yield, a well-managed Lemongrass crop here can gross roughly KES 480,000 per acre.
