Growing Pawpaw in Nandi

Soil suitability analysis based on Nandi's nutrient profile

Nandi County is a challenging environment for Pawpaw (soil-match score 35/100) and will need significant amendment before planting. Local soils average pH 6.17 — slightly acidic to near-neutral and inside the 6–7.5 band Pawpaw prefers, so no lime is usually required. Nitrogen (1.37 g/kg), phosphorus (26.4 mg/kg) and potassium (207 mg/kg) all meet Pawpaw's requirements, so a maintenance fertilizer programme is enough. Pawpaw prefers sandy loam soils, while Nandi is largely clay loam, so drainage and organic-matter management matter more here. At 1900 m, the county sits above Pawpaw's preferred altitude ceiling of 1200 m, where frost risk and cold nights reduce the crop's productivity. Pawpaw's full potential is about 12,000 kg/acre (~KES 336,000/acre at KES 28/kg), but at Nandi's 35/100 suitability a realistic target here is closer to 5,250 kg/acre (~KES 147,000/acre) unless the constraints above are addressed.
