Growing Spinach in Lamu
Soil suitability analysis based on Lamu's nutrient profile
Yes — Lamu is well suited to Spinach. Lamu's soil (pH 6.31, slightly acidic) gives Spinach a suitability score of 78/100. Match fertilizer to Lamu's nitrogen and phosphorus levels for the best result.
Lamu County is well suited to Spinach, scoring 78/100 on ShambaIQ's soil-match model. Local soils average pH 6.31 — slightly acidic to near-neutral and inside the 6–7.5 band Spinach prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.74 g/kg, P 9.6 mg/kg, K 117 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. Spinach prefers loam soils, while Lamu is largely sandy, so drainage and organic-matter management matter more here. 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.
