The Payoff of Recycling Nursery Water
Pitton, B.J.L., Oki, L.R., Haver, D.L., Johnson, G.E. (University of California Davis)
A large nursery in southern California installed an irrigation runoff capturing system to reduce water expenses and the production quality if the water supply was interrupted. They use a large amount of water, about 1,000 ac-ft/yr at a cost of $944 per ac-ft, so it is also a large expense. In two years, the nursery reused 1,022 ac-ft or about 50% of total water used for irrigation. For those two years, recycling irrigation runoff water saved $809,000. Even though the cost of the project was $900,000, it was recovered in the first year by grants, rebates, and water savings.

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.
