Nyandarua County is well suited to Garden Peas, scoring 81/100 on ShambaIQ's soil-match model. At an average pH of 5.38 the soil is moderately acidic, below Garden Peas's preferred 5.5–7 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 Garden Peas's requirements, so a maintenance fertilizer programme is enough. Garden Peas prefers sandy loam soils, while Nyandarua is largely clay, so drainage and organic-matter management matter more here.
