Carolina Nitrogen-Fixation Study Kit
For a class of 30 students. Members of the genus Rhizobium exist in a symbiotic relationship with leguminous plants. The Rhizobium growing in nodules on the roots of leguminous plants fix atmospheric nitrogen (N2). This supplies the plant with nitrates and the bacteria with energy and a favorable environment. In farming, legumes are plowed under, adding significant amounts of N2 to the soil. Nodules can be observed on the roots 6 weeks after planting.
