The January 2009 CTAHR Research News is now available for download. As we begin our 5th edition of the CTAHR Research News, we feature scientists in CTAHR involved in "sustainability" across various disciplines in CTAHR. Our cover story is about Dr. Ted Radovich of the Department of Plant and Soil Sciences. Ted has woven an excellent story about his lab's research and educational activities in cropping systems and improving soil fertility. Dr. Radovich is also the primary advisor to CTAHR's Sustainable and Organic Farm Training Garden - CTAHR's student-run organic garden at the Waimanalo Experiment Station. Dr. Radovich and others are also significant contributors to CTAHR's Sustainable Agriculture and Organic Agriculture web sites. We also feature six short stories on other faculty efforts related to sustainability, including Dr. Koon-*** Wang from the Department of Plant and Environmental Protection Sciences about her research on nematode control. Dr. Richard Bowen from the Department of Natural Resources and Environmental Management along with Mr. Ken Love, of the Hawaii Tropical Fruit Growers Association, discuss the "12 Trees Project" and work done with tropical fruit growers to establish relationships between farmers and culinary programs. Dr. Anne Alvarez of the Department of Plant and Environmental Protection Sciences shares her work on using plant oils to defend plants against bacterial infections. Dr. Ali Fares, a research hydrologist with the Department of Natural Resources and Environmental Management explains efforts to efficiently manage soil moisture and other nutrients for farmers. Dr. Kent Kobayashi and others from the Departments of Tropical Plant and Soil Sciences and Plant and Environmental Protection Sciences tell us about their efforts to help ornamental growers to be more sustainable. Finally, we update you on an important story that will affect the "sustainability" of Hawaii's agriculture, Dr. Mark Wright of the Department of Plant and Environmental Protection Sciences talks about work done to protect Hawaii's honey bees from the deadly Varroa mite. In this edition, we also have our regular features - the Research Calabash with lots of short items important for researchers, recent publications by CTAHR faculty, recent grants and an update on where CTAHR is in grants intake and finally, open funding opportunities. We hope you will enjoy this new issue of the CTAHR Research News - all about sustainability. As always we welcome your comments, both positive and negative and suggestions for improvements.
