“…Although the volume of water and application efficiency are vitally important to conserving water, water quality experts are also concerned about the presence of pathogens and agrichemicals in irrigation runoff from these same operations (Raudales, Parke, Guy, & Fisher, 2014;White, 2013b;Wilson, Riiska, & Albano, 2010). For example, in the U.S. there is a concern that contaminated water could impact plant communities in areas such as the Florida Everglades, the Chesapeake Bay watershed, the Great Lakes Basin, and the San Francisco Bay (White, 2013a;Wilson & Boman, 2011;Wilson & Foos, 2006). Water treatment technologies have been developed to reduce or eliminate possible biological contaminants from water including chlorine gas, sodium hypochlorite, ozone, ultraviolet radiation (UV), copper ionization, and heat treatments (Fisher, Raudales, & Meador, 2010).…”

Nursery and greenhouse operations require significantly large amounts of water to maintain product quality and often use more than what is needed by the crop being grown. The nursery industry’s use of water is highly criticized and adds to arguments against agricultural water use with increasingly limited water resources available globally. The purpose of this study was to explore the barriers and motivators associated with nursery and greenhouse growers’ adoption of water conservation and treatment technologies. In-depth interviews were conducted with 24 operators across the U.S. to identify their perceptions of new water-saving technologies and treatments based on the five attributes of an innovation identified by Rogers (2003). The findings revealed growers are aware of water-saving technologies and the rate of adoption depends on a variety of factors including: perceived cost, lack of ability of their workforce to use the new technology due to its complexity, and belief that their product will be worth more if it is grown in an environmentally-friendly manner. Barriers to adoption included the high cost of replacing equipment, incompatibility with existing systems, and the perception that new technologies do not fit in with the traditional hands-on approach to horticulture. Suggested extension programs to reach growers include developing materials that highlight the economic benefit of adoption and cost recovery, YouTube videos that reduce issues with perceived complexity growers can use with their workers, and programs that emphasize how technology fits in with the culture of the horticulture industry.

“…Fertilizers deliver plant essential mineral nutrients to ensure optimal growth, but application of fertilizers in excess of plant requirements can result in nutrient leaching; of particular environmental concern are nitrogen (N) and phosphorus (P). Fertilizer runoff from agriculture, including specialty crop production, is a major problem in a number of impaired waterways and can lead to environmental problems such as algal blooms (Majsztrik and Lea-Cox 2013 ; Mangiafico et al 2009 ; White 2013a ). The ability to recycle mineral nutrients is perceived as a benefit for some growers, and these recycled fertilizer salts are sometimes accounted for in their nutrition programs, particularly in greenhouse production (White et al 2013 ).…”

While governments and individuals strive to maintain the availability of high-quality water resources, many factors can “change the landscape” of water availability and quality, including drought, climate change, saltwater intrusion, aquifer depletion, population increases, and policy changes. Specialty crop producers, including nursery and greenhouse container operations, rely heavily on available high-quality water from surface and groundwater sources for crop production. Ideally, these growers should focus on increasing water application efficiency through proper construction and maintenance of irrigation systems, and timing of irrigation to minimize water and sediment runoff, which serve as the transport mechanism for agrichemical inputs and pathogens. Rainfall and irrigation runoff from specialty crop operations can contribute to impairment of groundwater and surface water resources both on-farm and into the surrounding environment. This review focuses on multiple facets of water use, reuse, and runoff in nursery and greenhouse production including current and future regulations, typical water contaminants in production runoff and available remediation technologies, and minimizing water loss and runoff (both on-site and off-site). Water filtration and treatment for the removal of sediment, pathogens, and agrichemicals are discussed, highlighting not only existing understanding but also knowledge gaps. Container-grown crop producers can either adopt research-based best management practices proactively to minimize the economic and environmental risk of limited access to high-quality water, be required to change by external factors such as regulations and fines, or adapt production practices over time as a result of changing climate conditions.

Nursery and greenhouse producers, research and extension faculty, and representatives from allied fields collaborated to formulate a renewed vision to address water issues affecting growers over the next 10 years. The authors maintained the original container irrigation perspective published in “Strategic vision of container nursery irrigation in the next ten years,” yet broadened the perspective to include additional challenges that face nursery crop producers today and in the future. Water availability, quality, and related issues continue to garner widespread attention. Irrigation practices remain largely unchanged due to existing irrigation system infrastructure and minimal changes in state and federal regulations. Recent concerns over urbanization and population growth, increased climate variability, and advancements in state and federal regulations, including new groundwater withdrawal limitations, have provided an inducement for growers to adopt efficient and innovative practices. Information in support of the overarching issues and projected outcomes are discussed within.
