Growing Pawpaw in Embu

Soil suitability analysis based on Embu's nutrient profile

Pawpaw can be grown in Embu County, but the soil scores 45/100 and needs targeted management to reach full potential. At an average pH of 5.1 the soil is moderately acidic, below Pawpaw's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen and potassium — measured at N 1.04 g/kg, P 12.6 mg/kg, K 194 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing those deficits. Pawpaw prefers sandy loam soils, while Embu is largely clay loam, so drainage and organic-matter management matter more here. Pawpaw's full potential is about 12,000 kg/acre (~KES 336,000/acre at KES 28/kg), but at Embu's 45/100 suitability a realistic target here is closer to 6,750 kg/acre (~KES 189,000/acre) unless the constraints above are addressed.
