The long-term productivity of forest ecosystems depends on the cycling of nutrients. The effect of carbon dioxide fertilization on forest productivity may ultimately be limited by the rate of nutrient cycling. Contemporary and future disturbances such as climatic warming, N-deposition, deforestation, short rotation sylviculture, fire (both wild and controlled), and the invasion of exotic species all place strains on the integrity of ecosystem nutrient cycling. Global differences in climate, soils, and species make it difficult to extrapolate even a single important study worldwide. Despite advances in the understanding of nutrient cycling and carbon production in forests, many questions remain. The chapters in this volume reflect many contemporary research priorities. The thirteen studies in this volume are arranged in the following subject groups: • N and P resorption from foliage worldwide, along chronosequences and along elevation gradients; • Litter production and decomposition; • N and P stoichiometry as affected by N deposition, geographic gradients, species changes, and ecosystem restoration; • Effects of N and P addition on understory biomass, litter, and soil; • Effects of burning on soil nutrients; • Effects of N addition on soil fauna.

From the research results and discussions presented in this book it becomes clear that a profound understanding of the various interrelationships of the nutritional aspects allows the implementation of specific management strategies to improve stability and productivity of forest ecosystems. In particular the effects of environmental changes as related to the impacts of air pollution, global change and land use on nutrient uptake and cycling processes in forest ecosystems are dealt with in detail. The book is divided into six main issues and each topic contains reviews as well as selected results of recent studies.

Brings together much of the recent literature on nutrient cycling due to conversion of forests to croplands, pastures, and plantation forests. It explains why nutrients are often very critical in tropical humid ecosystems and discusses principles that can guide land managers to conserve nutrients and sustain productivity.

Cycling of Mineral Nutrients in Agricultural Ecosystems contains the papers presented in the first international environmental symposium of the Royal Netherlands Land Development Society held at Amsterdam on 1976. The symposium is cosponsored by the International Association for Ecology and Elsevier Scientific Publishing Company. This compilation reflects the exchange of information and ideas by specialists and participants of the symposium. The book is comprised of nine chapters, which cover the following concepts of nutrient cycling in agricultural ecosystems: principles and control of nutrient cycling; description and classification of agro-ecosystems; nutrient cycling data from different countries; and general discussion on nutrient balances, changes in soil pools, manipulations, and future researches. This book also offers potential background and perspectives for further studies on nutrient cycling in agro-ecosystems, presenting a view on what directions future research should take. This volume will be an invaluable reference source for environmental science students and professionals. Research workers in agriculture and other environmental disciplines will also find this book useful.

Nutrient cycling is a cyclic process that includes the use, transfer and recycling of nutrients in the ecosystem. It involves the transfer of nutrients from the physical environment to living organisms and back to the physical environment. Nutrient cycling involves both biotic and abiotic components. Abiotic components include air, water and soil, whereas trees, animals and plants are biotic components. Gaseous cycling and sedimentary cycling are the two types of nutrient cycling. Gaseous nutrients such as carbon, hydrogen, nitrogen and oxygen are recycled in water, air and soil. Contrarily, nutrients such as calcium, phosphorus, and potassium are recycled mostly in soil. Plants in forest ecosystems require these nutrients for their metabolism, development and reproduction. Nutrient cycle help ecosystems function and restore ecological equilibrium by sustaining species, and genetic and ecosystem variety. This book unravels the recent studies on nutrient cycling. It aims to serve as a resource guide for students and experts alike and contribute to the growth of research on this topic.

Forest ecosystem is a self-sustaining functional unit of nature wherein living organisms interact among themselves and with the surrounding physical environment. It is a type of terrestrial ecosystem. Both biotic and abiotic elements such as soil, trees, insects, animals, birds and humans are a part of the forest ecosystem. There are four major components of a forest ecosystem, namely, productivity, decomposition, energy flow, and nutrient uptake and cycling. Nutrient cycle refers to a system that involves the movement of substances and energy between living organisms and non-living elements of the environment. This happens when plants and animals ingest nutrients present in the soil, which are then released back into the ecosystem after they die and decompose. Nutrient cycling is crucial for meeting the nutrient supply of plants in the forest and increasing productivity of forests. This book unfolds the important aspects of nutrient uptake and cycling in forest ecosystems, which will be crucial to develop a complete understanding of the subject matter. It is a resource guide for experts as well as students.

Over the past decade there has been considerable interest in the effects of atmospheric deposition on forest ecosystems. This volume summarizes the results of the Integrated Forest Study (IFS), one of the most comprehensive research programs conducted. It involved intensive measurements of deposition and nutrient cycling at seventeen diverse forested sites in the United States, Canada, and Norway. The IFS is unique as an applied research project in its complete, ecosystem-level evaluation of nutrient budgets, including significant inputs, outputs, and internal fluxes. It is also noteworthy as a more basic investigation of ecosystem nutrient cycling because of its incorporation of state-of-the-art methods, such as quantifying dry and cloud water deposition. Most significantly, the IFS data was used to test several general hypotheses regarding atmospheric deposition and its effects. The data sets also allow for far-reaching conclusions because all sites were monitored over the same period using comparable instruments and standardized protocols.
