objectives of the pilot study are to:
Potential benefits of a willow-based ET cover system include:
2003: Project was proposed to the New York State Department of Environmental Conservation (NYSDEC).
2004: First willow plantings on Settling Basin 13 in previously amended wastes and control plots.
2005: Field trial of different organic amendment mixtures (Field 3) commenced.
2007: First harvest on Field 1
2008: Commenced 10-acre demonstration on Settling Basin 14.
2009: Planning commenced for 25-acre expansion in 2010.

August 2010: Prepared a proposal in collaboration with colleague Don Leopold (SUNY ESF, EFB) for "Inland Salt Marsh Demonstration Project: Maintenance, Monitoring of Soils, Vegetation and Evapotranspiration."
May 2010: Deborah's study concluded that the two vegetated plots had the least soil moisture and soil temperature throughout the study period compare to the unvegetated control plots. The SHAW model estimated ET rates that were slightly greater in the vegetated than in the control plots, which resulted in lower percolation rates in the vegetated plots. Differences in soil moisture and temperature between the two vegetated plots indicate that the different morphological structure of the willow canopies can be considered in site design to reduce soil moisture, reduce percolation and regulate soil temperature.
April 2010: Andrew, Mackenzie and Jen (all undergrad research assistants) present a poster at the College's Spotlight on Research detailing their analysis of percolation through the 0.5m of amended Solvay waste.
August 2009: Deborah Ofori starts collecting canopy and soil temperature to compare with predictions by the SHAW model on SB 14. Canopy in this second growing season is closing, and appears relatively healthy.
July - December 2008: Research assistant Andrew Frazell assists with evacuating pan lysimeters to determine percolation rates through the shallow unsaturated wastes. Weeds are prolific.
May-June 2008: O'Brien & Gere constructed a 10-acre demonstration project at SB14. The organic amendment was mixed with Solvay waste using full-scale equipment to an 18-inch mix depth. The phot shows the organic amendment (brown) spread prior to mixing with the waste (white-gray).
January 2008: Field 1 was harvested and willow stockpiled for use in biomass refinery research. Note the stools in the foreground, which will sprout rapidly as soil warms up in March and April.
October 2006: By now, the differences amongst treatments is noticeable. Field 1 has achieved canopy closure. Field 2 (willow planted in Solvay waste without organic amendments) is barely surviving. Field 3 is starting to show differences amongst treatments.
July 2006: Graduate students Dan Brown and Danielle Benati measure hydraulic conducitivity in Field 3. Two willow varieties were planted using 10-inch cuttings two to three months earlier. The vigorous growth is similar to agrocultural fields and has an immediate effect on the site's water budget.
June 2005: Yard waste mulch and biosolids from two local wastewater treatment plants are applied to reseach plots to determine effect of different combincations on survival and growth.
April 2005: First year growth in Field 1 underscores the importance of organic amendments to improve growing conditions for willows planted directly in contact with the Solvay waste.
June 2004: Larry Abrahamson discovers that Solvay waste is characteristically white and can be readily trenched with vertical walls. Hundreds of thousands of dollars are spent annually by Honeywell to investigate and design remedial actions across the many wastebeds. This is a scene from the parking lots at the State Fairgrounds.
Graduate student Andy Johnson also discovers that ponds are created in the center of the settling basins due to runoff events, indicating the relatively low infiltration capacity of the waste. This scene is from SB14 in June 2004; a flock of geese has just flown from the pond.
April 2004: Senior forest engineering students visit Field 1 to finalize their proposed design for an ET landfill cover.
April 2003: We made a first site visit to the settling basins in Camillus, NY. There are some pioneer poplar and willow, but vegetation is sparse and shallow-rooted due to lack of nutrients in solvay waste and high pH (8.5 and higher). High moisture retention results in frozen soils in winter which impacts rooting.
