I think you're confusing nodal with nodule. Nodes are where leaves meet stem, and occasionally some plants will also produce roots there called adventitious roots.
Nodules are swellings on legume (e.g, soyben) roots that aid in nitrogen fixation (free fertilizer!). They house nitrogen fixing bacteria called Rhizobia.

Most of the legumes (peas and beans) have lumps (nodes or nodules) in their roots that contain nitrogen fixing bacteria. The nitrogen fixed is then available to the plant.
Graminae (grasses) don't have them. I'm not aware of anything in the grasses that is special, but I could be wrong.
