| Résumé : |
"The alarming paucity of information on biological indicators of soil quality and methods for integrating physical, chemical, and biological soil properties with soil management practices to assess soil quality led to this special publication,Defining Soil Quality for a Sustainable Environment. This chapter discusses approaches to defining and assessing soil quality and suggests one possible form for a soil quality index. It is essential that basic soil quality indicators relate to ecosystem functions such as C and N cycling and are components of driving variables for process- oriented models that emulate the ways ecosystems function. Evaluating the diverse effects of climate and management on soil function requires integration of basic physical, chemical, and biological indicators.

This chapter discusses approaches to defining and assessing soil quality and suggests one possible form for a soil quality index. It is essential that basic soil quality indicators relate to ecosystem functions such as C and N cycling and are components of driving variables for process- oriented models that emulate the ways ecosystems function. Evaluating the diverse effects of climate and management on soil function requires integration of basic physical, chemical, and biological indicators. The ability to assess soil quality and identify key soil properties is complicated by the many issues defining quality and the multiplicity of physical, chemical, and biological factors that control biogeochemical processes and their variation in time, space, and intensity."
