ATS Proceedings | Bouyoucos Conference on Constructed Rootzones

Applied Turfgrass Science Proceedings | The Bouyoucos Conference on the Advances
in Research on Soil Biological, Chemical and Physical Properties for Sustainable
Constructed Rootzones

May 20−23, 2012 • Philadelphia, PA, USA

Schedule | Sponsors

Thank you for taking time to visit the proceedings of The Bouyoucos Conference on Constructed Rootzones.

The conference was attended by 51 participants representing 9 countries, and we extend our thanks to all the attendees and to the authors of these proceedings. The goal of the conference was to explore the frontiers of recent soil biophysical, biochemical, and hydrological research, and to stimulate an interdisciplinary exchange of research-based information resulting in the development of novel experimental approaches and solutions to develop sustainable performance and productivity standards of constructed rootzones.
The conference assembled leading agronomy, plant, and soil scientists, with eminent researchers working at the frontiers of soil physics, chemistry and biology to enhance our knowledge of constructed soils; encourage, establish and promote interdisciplinary research collaborations and exchange of research-based information among scientists from academia, government,
and industry to pursue, expedite, and transfer advances to the field; develop and explore novel research techniques and methods not normally discussed or considered among plant and soil scientists; and to construct multidisciplinary teams that generate research proposals for governmental agency support in understanding properties and functionality of constructed soil rootzones.

Conference outcomes included these proceedings and other published articles, initiation of a global network for the collaboration and exchange of information among applied and basic researchers, and identification of strategies and directions for future research in the area of sustainable, engineered soil-based systems and constructed rootzones.


Enjoy the proceedings!
