Growing Lettuce in Nyandarua
Soil suitability analysis based on Nyandarua's nutrient profile
Nyandarua County is a solid choice for Lettuce, with a soil-match score of 74/100. At an average pH of 5.38 the soil is moderately acidic, below Lettuce's preferred 6–7 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 Lettuce's requirements, so a maintenance fertilizer programme is enough. Lettuce prefers loam soils, while Nyandarua is largely clay, so drainage and organic-matter management matter more here. At current prices (about KES 50/kg) and a typical 7,000 kg/acre yield, a well-managed Lettuce crop here can gross roughly KES 350,000 per acre.
