Growing Lucerne in Marsabit
Soil suitability analysis based on Marsabit's nutrient profile
Possible but challenging — Marsabit is only marginally suited to Lucerne. Marsabit's soil (pH 8.22, alkaline) gives Lucerne a suitability score of 42/100. Match fertilizer to Marsabit's nitrogen and phosphorus levels for the best result.
Marsabit County is a challenging environment for Lucerne (soil-match score 42/100) and will need significant amendment before planting. At an average pH of 8.22 the soil sits above Lucerne's preferred 6.5–8 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.52 g/kg), phosphorus (37.3 mg/kg) and potassium (420 mg/kg) all meet Lucerne's requirements, so a maintenance fertilizer programme is enough. Lucerne prefers clay loam soils, while Marsabit is largely sandy, so drainage and organic-matter management matter more here. Lucerne's full potential is about 8,000 kg/acre (~KES 224,000/acre at KES 28/kg), but at Marsabit's 42/100 suitability a realistic target here is closer to 4,200 kg/acre (~KES 117,600/acre) unless the constraints above are addressed.
