Growing Lemongrass in Lamu

Soil suitability analysis based on Lamu's nutrient profile

Lamu County is a solid choice for Lemongrass, with a soil-match score of 63/100. Local soils average pH 6.31 — slightly acidic to near-neutral and inside the 5.5–7.5 band Lemongrass 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 medium/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. Lemongrass prefers loam soils, while Lamu is largely sandy, so drainage and organic-matter management matter more here. Lemongrass's full potential is about 8,000 kg/acre (~KES 480,000/acre at KES 60/kg), but at Lamu's 63/100 suitability a realistic target here is closer to 6,300 kg/acre (~KES 378,000/acre) unless the constraints above are addressed.
