Control of Nitrogen Levels in Trees
http://www.forestry.uga.edu/warnell/service/library/index.php3?docID=281
From an energy standpoint, uptake and reduction of nitrates with incorporation into an organic framework is one of the most expensive tasks a tree performs. It would hardly be worthwhile if useable nitrogen in the environment was not at a premium.

Nitrogen Prescriptions for Trees
http://www.forestry.uga.edu/warnell/service/library/index.php3?docID=283
Supplemental nitrogen fertilization should be treated as a fined-tuned, carefully considered, constantly modified, whole tree prescription process. The whole tree wins or loses with the changing reactions of one major organ or resource.

Nitrogen Transformations in Soils
http://www.forestry.uga.edu/warnell/service/library/index.php3?docID=279
Nitrogen is available for capture by a tree when an organism dies and decays, excretes nitrogen containing wastes, or sheds materials and parts.

Selected Literature: Nitrogen and Tree Growth
http://www.forestry.uga.edu/warnell/service/library/index.php3?docID=284
Nitrogen availability for tree health maintenance and growth is one of the most constraining essential element problems faced by shade and street trees. Effective nitrogen use by trees involves a complex set of interwoven events, processes, and organisms.…

Uptake and Reduction of Nitrogen in Trees
http://www.forestry.uga.edu/warnell/service/library/index.php3?docID=280
Adequate availability of nitrogen in soils is but one of the problems facing trees. Moving nitrogen inside the tree presents a number of unique problems and solutions.

Whole Tree Systems and Nitrogen Management
http://www.forestry.uga.edu/warnell/service/library/index.php3?docID=282
Trees are unique among plants for a variety of reason. The unique features of trees and their interactions with nitrogen, allow a manager to better care for tree and site resources.
