Growing Pigeon Peas in Trans Nzoia
Soil suitability analysis based on Trans Nzoia's nutrient profile
Trans Nzoia County is a solid choice for Pigeon Peas, with a soil-match score of 66/100. Local soils average pH 5.93 — slightly acidic to near-neutral and inside the 5–8 band Pigeon Peas prefers, so no lime is usually required. Nitrogen (1.68 g/kg), phosphorus (27.3 mg/kg) and potassium (213 mg/kg) all meet Pigeon Peas's requirements, so a maintenance fertilizer programme is enough. Pigeon Peas prefers sandy soils, while Trans Nzoia is largely clay loam, so drainage and organic-matter management matter more here. Pigeon Peas's full potential is about 600 kg/acre (~KES 45,000/acre at KES 75/kg), but at Trans Nzoia's 66/100 suitability a realistic target here is closer to 495 kg/acre (~KES 37,125/acre) unless the constraints above are addressed.
