Growing Spinach in Makueni

Soil suitability analysis based on Makueni's nutrient profile

Quick answer

Yes — Makueni is well suited to Spinach. Makueni's soil (pH 7.5, alkaline) gives Spinach 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 Spinach, scoring 77/100 on ShambaIQ's soil-match model. Local soils average pH 7.5 — alkaline and inside the 6–7.5 band Spinach 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/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Spinach, which favours loam. At current prices (about KES 25/kg) and a typical 8,000 kg/acre yield, a well-managed Spinach crop here can gross roughly KES 200,000 per acre.
