Growing Lucerne in Lamu

Soil suitability analysis based on Lamu's nutrient profile

Lamu County is a solid choice for Lucerne, with a soil-match score of 73/100. At an average pH of 6.31 the soil is slightly acidic to near-neutral, below Lucerne's preferred 6.5–8 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. 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/high demand — so the fertilizer plan below prioritises closing those deficits. Lucerne prefers clay loam soils, while Lamu is largely sandy, so drainage and organic-matter management matter more here. At current prices (about KES 28/kg) and a typical 6,500 kg/acre yield, a well-managed Lucerne crop here can gross roughly KES 182,000 per acre.
