Growing Eggplant in Lamu

Soil suitability analysis based on Lamu's nutrient profile

Lamu County is a challenging environment for Eggplant (soil-match score 0/100) and will need significant amendment before planting. Local soils average pH 6.31 — slightly acidic to near-neutral and inside the 5.5–7 band Eggplant 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/high/high demand — so the fertilizer plan below prioritises closing those deficits. Eggplant prefers loam soils, while Lamu is largely sandy, so drainage and organic-matter management matter more here. At 10 m, the county sits below Eggplant's preferred altitude range (500–1800 m), which limits yield potential due to heat stress. At current prices (about KES 50/kg) and a typical 8,000 kg/acre yield, a well-managed Eggplant crop here can gross roughly KES 400,000 per acre.
