Growing Lucerne in Lamu

Soil suitability analysis based on Lamu's nutrient profile

Quick answer

Yes, with the right inputs — Lamu is moderately suited to Lucerne. Lamu's soil (pH 6.31, slightly acidic) gives Lucerne a suitability score of 73/100. Match fertilizer to Lamu's nitrogen and phosphorus levels for the best result.

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. On ShambaIQ's soil-match model, Lucerne is the #44 soil match of the 106 crops we assess for Lamu County. At current prices (about KES 28/kg) and a typical 8,000 kg/acre yield, a well-managed Lucerne crop here can gross roughly KES 224,000 per acre.
