Doug Karlen, - an amazingly productive, creative and thoughtful soil and water conservation research scientist at the USDA ARS National Lab for Agriculture and the Environment in Ames, IA, - retired on March 2, 2019. A wonderful and very fitting retirement celebration was held on that day in his honor in Kansas City, MO that brought together many family members, colleagues and friends to recognize the great career that Doug has had as well as the many ways he touched so many people with this integrity, passion, and his simply superb ability to build and lead teams and conduct integrated soil and crop management research over his forty-year career with ARS. For folks who do not know Doug, he was truly an exceptionally productive and influential scientist and leader in the development of soil health indexes and technology transfer programs, sustainably increasing crop yields, and using agricultural crops for bioenergy production. Not only was he a Fellow in the American Society of Agronomy, the Crop Science Society of America, and the Soil Science Society of America, but he also was recognized as an ARS Distinguished Senior Research Scientist and recipient of the Albert Nelson Marquis Lifetime Achievement and Hugh Hammond Bennett Awards. In addition, Doug was truly a very good friend to CASI and the work that we've been doing here in California. He came out to work with us on some of the very early soil quality indexing efforts that he and his then Post-Doc, Susan Andrews, pioneered way back in the early 2000's and since then has also returned for a number of very nice meetings and discussions with various CASI groups. We salute Doug Karlen, a true friend and very good person!
