Kiambu County is well suited to Garden Peas, scoring 79/100 on ShambaIQ's soil-match model. At an average pH of 5.28 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 (1.01 g/kg), phosphorus (13.7 mg/kg) and potassium (169 mg/kg) all meet Garden Peas's requirements, so a maintenance fertilizer programme is enough. Garden Peas prefers sandy loam soils, while Kiambu is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Garden Peas is the #15 soil match of the 106 crops we assess for Kiambu County. At current prices (about KES 145/kg) and a typical 2,500 kg/acre yield, a well-managed Garden Peas crop here can gross roughly KES 362,500 per acre.
