Global Organization of Terrestrial Plant-Nutrient Interactions

The global extent of earth system change is challenging plant ecologists and physiologists to understand the organization of plant-nutrient relations across scales of observation, from leaf physiology to biosphere feedbacks. Central to this concern are the roles of nitrogen (N) and phosphorus (P) as the major growth-limiting nutrients for plant communities worldwide and as determinants of key physiological processes such as photosynthetic CO2 fixation and cellular biosynthesis.
