Comparison of Three Production Scenarios for Buxus microphylla var. japonica ‘Green Beauty’ Marketed in a No. 3 Container on the West Coast Using Life Cycle Assessment
Ingram, D.L., Knight, J. (University of Kentucky), Hall, C.R. (Texas A&M)
The impact of west coast production scenarios for boxwood marketed in a #3 container on carbon footprint (CF; kilograms of carbon dioxide equivalents (kg CO2e)) and variable costs at the nursery gate for Scenario A (propagation to #1 to #3 container) was 2.198 kg CO2e with variable costs of $4.043. Scenario B (propagation to field to #3 container) was a CF of 1.717 kg CO2e with variable costs of $2.880 and take a year longer in production than the other two models. The CF of Scenario C (propagation to #1 to #2 to #3 containers) would be 3.364 kg CO2e with variable costs of $5.733. Containers, transplants/transplanting, irrigation, and fertilization accounted for the greatest portion of CF and variable costs in each scenario.

Diffusing Water Conservation and Treatment Technologies to Nursery and Greenhouse Growers
Lamm, A.J., Warner, L.A., Taylor, M.R., Martin, E.T., Fisher, P. (University of Florida), White, S. (Clemson University)
In-depth interviews were conducted with 24 operators across the U.S. to identify their perceptions of new water-saving technologies and treatments. 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. We need to develop materials that highlight the economic benefit of adoption and cost recovery, YouTube videos that reduce issues with perceived complexity should also be developed for growers so they can use them with their workers.

What is the Cost of Your Water?
Raudales, R. (University of Connecticut), Fisher, P. (University of Florida), Hall, C.(Texas A&M University)
This article focuses on the cost of irrigation water including the water source, fertilizer and treatment. The cost of water concludes the three-part series on irrigation water in GPN magazine.
