Growing Spinach in Nyandarua
Soil suitability analysis based on Nyandarua's nutrient profile
Yes, with the right inputs — Nyandarua is moderately suited to Spinach. Nyandarua's soil (pH 5.38, strongly acidic) gives Spinach a suitability score of 69/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Nyandarua County is a solid choice for Spinach, with a soil-match score of 69/100. At an average pH of 5.38 the soil is moderately acidic, below Spinach's preferred 6–7.5 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 Spinach's requirements, so a maintenance fertilizer programme is enough. Spinach prefers loam soils, while Nyandarua is largely clay, so drainage and organic-matter management matter more here. Spinach's full potential is about 8,000 kg/acre (~KES 200,000/acre at KES 25/kg), but at Nyandarua's 69/100 suitability a realistic target here is closer to 6,900 kg/acre (~KES 172,500/acre) unless the constraints above are addressed.
