The Cost of Filtration
Raudales, R. (University of Connecticut), Fisher, P. (University of Florida), Hall, C.(Texas A&M University)
Filtration is an important step in capture and re-use of irrigation water. This article presents filtration systems, the initial cost, and the cost to treat 1,000 gallons of water. Filtration is the first article in the three-part series of water management in GPN magazine.
The Cost of Filtration (1) can be found in the link bellow.

Carbon Footprint and Variable Costs of Production Components for a Container-grown Evergreen Shrub Using Life Cycle Assessment: An East Coast U.S. Model
Ingram, D.L. (University of Kentucky), Hall, C.R. (Texas A&M University), Knight, J. (University of Kentucky)
Production components of an evergreen shrub (Ilex crenata) grown in a #3 container in an east coast U.S. nursery are analyzed for their costs and contributions to carbon footprint (CF), including product impact in the landscape throughout its life. The propagation-to-landscape CF for an individual plant was 2.337 kg CO2e with variable costs from cutting-to-gate of $3.224. After accounting for carbon sequestered in the landscape by the plant, the plant’s CF drops to -1.445 kg CO2e. Major contributors to CF and costs are discussed. This information can communicate economic and environmental value of green industry products to the consuming public.

The Cost of Irrigation Sources and Water Treatment in Greenhouse Production
Raudales, R.E. (University of Connecticut), Fisher, P.R. (University of Florida), Hall, C.R. (Texas A&M University)
In this article, 11 greenhouse operations were surveyed to provide cost analysis of screen filters, synthetic fiber filters, control of pathogens, and water sources. The cost analysis may aid in informed descisions when considering recirculation or recycling of irrigation water.
