Completed Research Projects
This multidisciplinary project will promote the use of biochar and bio-oil generated from agricultural/forest organic wastes to enhance small farm sustainability through providing renewable fuel, and improving soil quality and crop productivity, and to improve the environment through sequestrating greenhouse gases and reducing the mobility and exposure of contaminants in soils.
This project will examine the effect of natural diversity on biofuel production efficiency by using a grass energy model organism (Brachypodium distachyon), and treatment with both biological and thermochemical conversion.
Reaching the potential for renewable biofuels depends on the development of new technologies that are able to release the energy stored in cellulose fibers. This research project centers around an unusual microbe, Clostridium phytofermentans, that can convert a broad range of biomass sources directly to ethanol without expensive thermochemical pretreatment. Further development of conversion processes using C. phytofermentans will create a path to renewable biofuels using our region's sustainable forestry and crop resources.
This project utilizes robotic submersible technology to characterize submerged aquatic vegetation (SAV) blooms in the Charles River in Massachusetts.
This project involves monitoring the levels and locations of EDCs (endocrine disrupting compounds) in the Assabet River of eastern Massachusetts to advance the protection of the aquatic environment.
Researchers will evaluate the potential use of field indicators of hydric soils to characterize wetland hydroperiods with respect to frequency, depth, and duration of water table fluctuations; test the effectiveness of proposed hydric soil indicators to identify 'problem hydric soils'; test monitoring protocols used to identify reducing conditions to determine if they are effective within a range of soil conditions within the Northeast; and investigate the hydraulic properties of hydromorphic soils with episaturation.
This project has three components to increase sustainability in Massachusetts cranberry production:
- development and demonstration of sustainable practices for the management of the most severe pest problems: cranberry fruitworm, fruit rot disease, and the parasitic weed dodder.
- investigation of practices to conserve water and fuel.
- work with growers to implement nutrient management Best Management Practices (BMPs).
This project will study and numerically model road salt impact on water quality in a typical aquifer in eastern Massachusetts.
This study will examine threats to water security and potential impacts on water quantity and quality in watershed systems. The main goal of the study is to evaluate the effects of land use, extreme precipitation, and climatic stressors on water security (quantity and quality) and potential mitigation opportunities at a river basin scale. Geographic Information Systems (GIS), uncertainty analysis, simulation modeling, and a multi-attribute decision framework will be used to evaluate and advance water security in watershed systems.
With increased pressure to utilize more practical, ecological and economically feasible strategies to manage turfgrasses, research is needed to identify best management practices to preserve water resources. The primary goal is to increase sustainability of turfgrass by addressing water conservation issues, including (i) efficient irrigation strategies based on actual turfgrass water use, (ii) drought resistant species and cultivars, and (iii) an artificial wetland system to aid in preservation of water quality from managed turf settings.
