A provocative proposal accounts for the 'why and when' of that event. Christina Curell amir ameri Abstract and Figures. Through a partnership with symbiotic organisms in their roots, these plants can turn atmospheric nitrogen into nitrogen fertilizers useful to themselves but also becoming available to their neighbors over time through root die back, leaf fall, and chop. Leguminous plants such as beans and peas do this as well as many other different types of trees, bushes, and shrubs. Once soil is healthy enough to support mature trees, nitrogen fixers die out all on their own without human intervention. They also recover faster when confronted with disturbances. Such organisms are also called diazotrophs. These are the three classic signs your plants aren’t receiving enough nitrogen: 1.
