Growing Parsley in Kiambu
Soil suitability analysis based on Kiambu's nutrient profile
Kiambu County is a solid choice for Parsley, with a soil-match score of 65/100. At an average pH of 5.28 the soil is moderately acidic, below Parsley's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen — measured at N 1.01 g/kg, P 13.7 mg/kg, K 169 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Parsley prefers loam soils, while Kiambu is largely clay, so drainage and organic-matter management matter more here. Parsley's full potential is about 4,000 kg/acre (~KES 400,000/acre at KES 100/kg), but at Kiambu's 65/100 suitability a realistic target here is closer to 3,250 kg/acre (~KES 325,000/acre) unless the constraints above are addressed.
