Growing Lettuce in Nyandarua
Soil suitability analysis based on Nyandarua's nutrient profile
Yes, with the right inputs — Nyandarua is moderately suited to Lettuce. Nyandarua's soil (pH 5.38, strongly acidic) gives Lettuce a suitability score of 74/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
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. On ShambaIQ's soil-match model, Lettuce is the #21 soil match of the 106 crops we assess for Nyandarua County. 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.
