Nitrogen stress and deficiency in trees can initiate early senescence and abscission of leaves. This process remobilizes nitrogen compounds within tissues to be shed and pulls nitrogen back into twig, branch, and stem areas behind shed leaves. Approximately 60% of nitrogen in a tree is remobilized and reallocated on an annual basis.
