The small-watershed approach to problems of nutrient cycling has these advantages. (i) The small watershed is a natural unit of suitable size for intensive study of nutrient cycling at the ecosystem level. (ii) It provides a means of reducing to a minimum, or virtually eliminating, the effect of the difficult-to-measure variables of geologic input and ...

Plant and Soil, 1995
This paper briefly reviews pathways by which plants can influence the nutrient cycle, and thereby the nutrient supply of themselves and of their competitors. Higher or lower internal nutrient use efficiency positively feeds back into the nutrient cycle, and helps to increase or decrease soil fertility. These tendencies are further enhanced by secondary

Because it is ultimately dispersed back to space as heat, energy flows in only one direction through an ecosystem. In contrast, the materials from which living matter is fashioned are in constant circulation back and forth between plants and animals and the non-living environment.

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.
