The concept was first suggested in 1977 with regard to the need to consider multiple land uses, even in intensive agriculture. Throughout the 1990s the concept received substantial attention especially by soil microbiologists, ecologists, the Natural Resources Conservation Service (NRCS), and sustainable agriculture organizations. Much more remains to be done, especially with regard to its application to soil remediation and other non-crop production uses. This discussion emphasizes that assessment of soil quality is not an end in itself, but rather a process that is intended to lead to a better public awareness of soil resources and, through that knowledge, to more sustainable land use decisions. Examples of how the concept is being applied in North America, Europe, New Zealand and other countries will be provided. Our goals are to provide the historical foundation for this symposia and through the ensuring discussion to demonstrate that the SSSA ad hoc committee definition of soil quality is an effective focus for our professional society. |
