Lamu County is well suited to Cassava, scoring 86/100 on ShambaIQ's soil-match model. Local soils average pH 6.31 — slightly acidic to near-neutral and inside the 4.5–7 band Cassava prefers, so no lime is usually required. The main gap is potassium — measured at N 0.74 g/kg, P 9.6 mg/kg, K 117 mg/kg against this crop's low/low/medium demand — so the fertilizer plan below prioritises closing that deficit.
