Storing Carbon in Agricultural Soils
Springer Science & Business Media, Oct 31, 2001 - Nature - 117 pages
Soil carbon sequestration can play a strategic role in controlling the increase of CO2 in the atmosphere and thereby help mitigate climatic change. There are scientific opportunities to increase the capacity of soils to store carbon and remove it from circulation for longer periods of time. The vast areas of degraded and desertified lands throughout the world offer great potential for the sequestration of very large quantities of carbon. If credits are to be bought and sold for carbon storage, quick and inexpensive instruments and methods will be needed to monitor and verify that carbon is actually being added and maintained in soils. Large-scale soil carbon sequestration projects pose economic and social problems that need to be explored.
This book focuses on scientific and implementation issues that need to be addressed in order to advance the discipline of carbon sequestration from theory to reality. The main issues discussed in the book are broad and cover aspects of basic science, monitoring, and implementation. The opportunity to restore productivity of degraded lands through carbon sequestration is examined in detail.
This book will be of special interest to professionals in agronomy, soil science, and climatology.

The convention aims at the ‘stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system'. In December

Support for the workshop was provided by the Environmental Protection Agency, the US Department of Agriculture, the Department of Energy, the Monsanto Company and NASA.

Page 6 - sequestration on these lands is probably even greater than on currently farmed lands. Improvements in rangeland management, dryland farming and irrigation can add C to soils in these regions and provide the impetus for changes in land management practices that will begin the essential process of stabilizing
Page 5 - Can methods be developed to increase still further the quantities of C that accumulate in soils and, perhaps more importantly, the length of time during which the C resides in soils? (2) Can opportunities for soil C sequestration be extended beyond the currently farmed lands to the vast areas of degraded and desertified lands worldwide? (3) Can we develop
