Access to high-quality irrigation water is increasingly limited for specialty crop production. Given the production, environmental, and economic issues associated with the use of lower quality, alternative (e.g., recycled) water sources, researchers from 10 institutions worked on a Coordinated Agriculture Project sponsored by the National Institute of Food and Agriculture, U.S. Department of Agriculture—through the Specialty Crops Research Initiative. Over the last 4 years, the Clean WateR3 project team has developed new science-based information resources that greenhouse and nursery growers can use to more efficiently use and manage water in their operations. Integration of research expertise from socioeconomic, environmental/ecological engineering, biological/ horticultural systems, plant pathology, and environmental toxicology disciplines enabled the Clean WateR3 team to holistically address grower concerns and integrate a variety of data into systems-based solutions growers can use to more efficiently manage water. A portion of the results from this project were presented at the 2018 ASHS meeting in Washington, DC, in three special sessions and are further detailed in the eight articles in this series.
The objectives of the three special sessions were to 1) provide perspectives related to water use by nursery and greenhouse producers and information on how to facilitate grower decision making; 2) detail various practices and treatment technologies that can help to manage nutrient, pesticide, and disease contaminants in water growers use for irrigation; and 3) show how outreach practices influence grower access to and use of research-based information. Each session was focused on an objective, with 13 presentations delivered over 3 d.
