Growing Parsley in Wajir

Soil suitability analysis based on Wajir's nutrient profile

Wajir County is a challenging environment for Parsley (soil-match score 1/100) and will need significant amendment before planting. At an average pH of 8.4 the soil sits above Parsley's preferred 6–7.5 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.52 g/kg, P 39.3 mg/kg, K 396 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Parsley prefers loam soils, while Wajir is largely sandy, so drainage and organic-matter management matter more here. Wajir receives approximately 200 mm/year — well below Parsley's minimum of 600 mm — so supplemental irrigation would be essential for this crop. Parsley's full potential is about 4,000 kg/acre (~KES 400,000/acre at KES 100/kg), but at Wajir's 1/100 suitability a realistic target here is closer to 50 kg/acre (~KES 5,000/acre) unless the constraints above are addressed.
