On the farm yesterday, fava plants were harvested for the compost. Fava are particularly valuable as Tess Tabot points out. What is she pointing at? Well, its a rhizobium, a nitrogen fixing nodule. It enjoys a symbiotic relationship with bacteria that digest material, provide nitrogen for the plant, especially at seed producing time.
