Growing Pawpaw in Makueni

Soil suitability analysis based on Makueni's nutrient profile

Quick answer

Yes — Makueni is well suited to Pawpaw. Makueni's soil (pH 7.5, alkaline) gives Pawpaw a suitability score of 77/100. Match fertilizer to Makueni's nitrogen and phosphorus levels for the best result.

Makueni County is well suited to Pawpaw, scoring 77/100 on ShambaIQ's soil-match model. Local soils average pH 7.5 — alkaline and inside the 6–7.5 band Pawpaw prefers, so no lime is usually required. The main gap is nitrogen — measured at N 0.86 g/kg, P 29.6 mg/kg, K 351 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Pawpaw, which favours sandy loam. At current prices (about KES 28/kg) and a typical 12,000 kg/acre yield, a well-managed Pawpaw crop here can gross roughly KES 336,000 per acre.
