Nitrogen & Trees: A Learning Manual

Described in its most basic form, a tree is a collection of carbon chains with a few other elements attached. There are many elements required for successful tree life. Some elements are needed in much higher proportions than others. What elements a tree requires for life may not be readily available within the environment in which it stands. Within terrestrial environments, usable nitrogen is usually in short supply — if not the most growth-limiting of all essential elements. Nitrogen is one of the key connectors between, and modifiers of, carbon chains
