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 ...

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.

Abstract This chapter investigates the effects of human usage of tropical rain forests on the ecosystem’s capital stock of plant mineral nutrients and on their cycles. First the nutrient cycling aspects of shifting agriculture are described, then nutrients and their cycles in primary rain forest.

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.

Nutrients have been discussed throughout this book in terms of limiting factors for producers, consumers, and decomposers, as electron donors for microbial decomposers, and in a number of other roles. It should be evident, then, that nutrients are inextricably linked to almost all ecological processes.
