For 35 years University of Minnesota Extension Master Gardener volunteers have been sowing seeds of success across Minnesota.

Examples of that success are described in the spring 2012 edition of Extension's Source magazine. A feature story tells how Master Gardeners in Isanti County have given back to their community in Cambridge, MN. Interest in the community garden they initiated in 2009 has grown significantly and benefits the community on several fronts. Other side articles in Source describe how Master Gardeners contribute to University research and how Master Gardener educational classes lead to citizens adopting greener gardening practices.

Master Gardeners don't just experiment with plant varieties on their own, they assist University of Minnesota faculty with research. Beginning in 2009, Master Gardeners in Dakota County aided Extension horticulturist Dr. Vince Fritz on a Brassica research project. The project set out to evaluate variety performance and to characterize each variety's relative health benefit based on the variety's phytonutrient concentration. Vegetables with high phytonutrient concentrations are thought to have preventative benefits against some forms of cancer. The research is directly connected to a collaborative study Dr. Fritz is conducting with the U's Masonic Cancer Center.

Master Gardeners helped to plant and maintain the trial plots at the University of Minnesota's Rosemount Research and Outreach Center (RROC). They also assisted with data collection and as co-educators about the research during annual open house events at the RROC. Later this year a variety trial report will be published. The report will include relative phytonutrient concentrations in each of the varieties trialed.

Dr. Fritz says of the Master Gardener volunteers, "I have thoroughly enjoyed working with the Master Gardeners in Dakota County over the years. Their enthusiasm, desire to learn, and desire to 'pass it on' is contagious."

MINNEAPOLIS / ST. PAUL (11/07/2011) --Can a single biofuel production system reduce water and nutrient runoff from farm fields, cut down on soil erosion and turn a profit for the farmers who grow it? University of Minnesota scientists and Extension Master Gardeners will explore this possibility as part of a new, five-year, $25 million multistate grant.

Funded by the USDA's National Institute of Food and Agriculture, nationwide research will focus on harvesting perennial grasses--mostly native species such as bluestem and switchgrass--and using the biomass as a feedstock for a biofuel process known as pyrolysis. Interdisciplinary research teams from eight states will explore the best ways to grow, harvest, transport and distribute the biomass and biofuel.

In Minnesota, research efforts will center on the use of biochar, a nutrient-rich solid and co-product of the pyrolysis process, as a soil amendment. To help determine biochar's viability as a commercial product for home gardeners, Master Gardeners will test its ability to increase productivity in vegetable and flower gardens. They will design, plant, maintain and collect data from research plots at three Minnesota sites: the St. Paul Campus Display Garden, the Rosemount Research and Outreach Center, and the Landscape Arboretum. In addition, Master Gardeners will share preliminary findings and results at horticulture days, open houses, field days and other public events statewide.

"The unique part is that Master Gardeners get to work on cutting-edge bioenergy research and bring those results out to the people of Minnesota," said Julie Weisenhorn, Master Gardener program state director.

U of M scientists from Extension and the departments of bioproducts and biosystems engineering; horticultural science; soil, water and climate; and applied economics will take part.

"What is so exciting about this project is that it has the potential to improve soil fertility of large agricultural fields as well as small gardens," said Jason Hill, assistant professor in the U's bioproducts and biosystems engineering department and one of the project's lead investigators.

The feasibility of biochar as a new commercial product for home gardeners may bode well for the future of clean energy options like bio-oil. Pyrolysis decomposes biomass to produce both biochar and bio-oil, which with additional refining can be turned into automobile fuels and petrochemicals. So-called "green gasoline" derived from bio-oil is considered a "drop-in fuel" that can be added directly to the U.S. gasoline infrastructure and delivery system.

In addition to the University of Minnesota, the five-year study involves researchers from Iowa State University, Purdue University, the University of Wisconsin, the University of Vermont, USDA research offices in Wisconsin, Pennsylvania and Nebraska, and the Department of Energy's Idaho National Laboratory.

University of Minnesota Extension is a 100-year-old partnership between the university and federal, state and county governments to provide scientific knowledge and expertise to the public. Through Extension, the University of Minnesota "extends" its resources to address critical public issues in priority areas, including food and agriculture, communities, environment, youth and families.
