Like other legumes, blue lupin fixes nitrogen in a symbiotic interaction with bacteria in the rhizosphere. The plant is used as green manure crop or as a grain lugume for animal feed or human sonsumption. Varieties low in alkaloids can be used for livestock or human comsumption. Due to its ability to fix nitrogen and its low nutrient requirement this plant is suitable to be sown on marginal fields as an improvement of the soil. Additionally, lupins have strong roots, which can reduce the compaction of soil.
