Lamu County is well suited to Groundnuts, scoring 86/100 on ShambaIQ's soil-match model. Local soils average pH 6.31 — slightly acidic to near-neutral and inside the 5–7 band Groundnuts prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 0.74 g/kg, P 9.6 mg/kg, K 117 mg/kg against this crop's low/medium/medium demand — so the fertilizer plan below prioritises closing those deficits.
