Growing Lemongrass in Nyandarua
Soil suitability analysis based on Nyandarua's nutrient profile
Yes, with the right inputs — Nyandarua is moderately suited to Lemongrass. Nyandarua's soil (pH 5.38, strongly acidic) gives Lemongrass a suitability score of 57/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Lemongrass can be grown in Nyandarua County, but the soil scores 57/100 and needs targeted management to reach full potential. At an average pH of 5.38 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 (1.28 g/kg), phosphorus (14 mg/kg) and potassium (166 mg/kg) all meet Lemongrass's requirements, so a maintenance fertilizer programme is enough. Lemongrass prefers loam soils, while Nyandarua is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Lemongrass is the #55 soil match of the 106 crops we assess for Nyandarua County. Lemongrass's full potential is about 8,000 kg/acre (~KES 480,000/acre at KES 60/kg), but at Nyandarua's 57/100 suitability a realistic target here is closer to 5,700 kg/acre (~KES 342,000/acre) unless the constraints above are addressed.
Better matched to Nyandarua's soil: Tea, Pyrethrum, and Potato — each scores higher on the same soil.
