Nutrient cycling studies were initiated in the late 1960s at Walker Branch Watershed in eastern Tennessee as part of the International Biological Program’s effort to characterize productivity and nutrient cycling in forests throughout the world (summarized by Cole and Rapp 1981).

The perception that the euphotic zone of nutrient-impoverished oceanic waters is a steady state system has been based, to a large extent, on the choice of temporal and spatial scales upon which the pertinent biological and chemical measurements typically are made. For example, subsamples obtained from well-mixed, large volume samples (liters to tens of

Nutrient Cycling and Nutrient Use Efficiency
The American Naturalist, 1982Forest ecosystems systematically produce more litterfall dry mass per unit of nitrogen in sites with less aboveground nitrogen circulation. This pattern is observed both within and among tropical, temperate deciduous, coniferous, Mediterranean, and fertilized ecosystems.

The circulation of nutrients is essential to the survival of all living things. The supply of water and oxygen, the temperature and acidity in the soil are of great significance to this process. In a tropical rainforest, the cycle is rapid because the temperature and humidity are just right.

The cycling of nutrient elements is the crux of all ecological considerations because of their limited availability in the biosphere. The concept of growthlimiting nutrients has been discussed in Chapter 2 as well as the essential elements for all biological systems. It follows that continued utilization of one element as a nutrient by a given category
