Research Project:
Fate of Agrochemicals in Pot-in-Pot Nursery Culture
Location: Application Technology Research Unit
2008 Annual Report
1a.Objectives (from AD-416)
To study the impact of pot-in-pot culture on nursery production and water management.
1b.Approach (from AD-416)
Studies will be designed that allow for collection of leachate to track fertilizer and soilless media components fate during pot-in-pot production. Four experimental plots have been established. Soilless media, leachate and tissue samples will be collected weekly for fertilizer and pesticide tracking. Water and fertilizer loss through drainage from the pot-in-pot, and changes in container medium moisture and temperature due to irrigation, rainfall and weather conditions will be recorded.
3.Progress Report
Continued studies were conducted that provided additional growth and leachate analyses for the pot-in-pot study at Willoway Nursery. Data analysis from four experimental plots, 3 pot-in-pot plots and 1 in hoop houses yielded water management information useful to the grower who has realized increased caliper of tree species, a 40% saving of water use. Research continues coordinated with ARS Horticulturist. As a result, the grower expanded the above project into an experiment of several acres.
The project was monitored through periodic reports and research meetings.
