Growing Parsley in Busia

Soil suitability analysis based on Busia's nutrient profile

Parsley can be grown in Busia County, but the soil scores 59/100 and needs targeted management to reach full potential. At an average pH of 5.29 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 0.91 g/kg, P 16.6 mg/kg, K 175 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Parsley, which favours loam. Parsley's full potential is about 4,000 kg/acre (~KES 400,000/acre at KES 100/kg), but at Busia's 59/100 suitability a realistic target here is closer to 2,950 kg/acre (~KES 295,000/acre) unless the constraints above are addressed.
