1 Bioenergy at the MU Bradford Research and Extension Center

2 Utilize Alternative Forms of Energy

3  Use ground heat to keep the pesticide storage area above freezing in the winter and cool in the summer.  Also air exchanges of 6 times per hour

4  Aren’t all Greenhouses Solar?  Yes, but a Passive Solar Greenhouse does not use an artificial heat source  Instead water, concrete, or some other heat holding material

5  Black 55 gallon Barrels filled with water  Rule of Thumb-2.5 gallons/ ft 2 of glazing for season extension or 5 gallons/ft 2 for all season

9  South Hip Wall Plastic being able to be rolled up and down  Allow for cooling in the warmer weather  Can be raised or lowered each day  Sealed down during the winter.

10 30 X 40 FT GREENHOUSE CORN STOVE

11  How Much Corn Do You Use?  In a insulated house on a cold day about 1 bushel/day  On a cold night in the greenhouse about 5-6 bushels  A 30 x 96 greenhouse uses about 200 gallons of propane per night when it is 15 degrees F

12

13  Stainless Steel  Pallet Burner  Saves 9,000 gallons of Propane each year

14

15  Solar and Wind Combination  10 kWatt System  700 kwatt/month  $75,000  Payback –probably not  Educational Value

16  Wind Anemometer Project with DNR  Measure the wind quality at 66 ft for one year

17  Building a Machine to compress switchgrass and corn stover into pellets.  Test Fired in our outside

18

19  Corn-1/3 Ethanol, 1/3 Distillers Grain, 1/3 CO2  Cellulosic Ethanol or Pelleting-100% Fuel  No animal feed

20  A monoculture of a grass will be essentially a desert for wildlife  Livestock?  Cost is driven up by N fertilizer  What if we had a mixed stand?

21  Minnesota Study Published in Science (Tillman et. al., 2006) Found More Biomass and Biofuel Potential When As The Diversity Increased  Use of Natives?

22  Use of Native Legumes for a N source  Also Provide Flexibility for Livestock

23

24  At MU Bradford Research and Extension Center  Low Input/High Diverse compared to a High Input/Monoculture  18 different forbs and legumes  Switchgrass and Big Bluestem  Cutting Height  Seasonal Harvests Depending on Need

25

26  Compare different crops for their ethanol production capibilities.  Native Warm Season Grasses, Miscanthus, Corn for grain and stover

27  Miscanthus  Switchgrass  Big Bluestem  Indiangrass  Sweet Sorghum  Continuous Corn- Grain  Continuous Corn- Grain and Stover  Corn/Soybean rotation for Grain  Tall Fescue as a control

28  Look at Economics  Look at Soil Properties  If remove large amount of biomass what is that going to do to soil properties

29  Grasses for Ethanol  Switchgrass, Indiangrass, Eastern Gamma, Big Bluestem, Miscanthus  Grains and Sugar Crops for Ethanol  Corn, Grain Sorghum, Sweet Sorghum, Sugar Cane, Sugar Beets  Oil Crops  Soybeans, Canola, and Sunflower

30  Felix Fritschi  Sweet Sorghum  Varieties  N timing  Bill Wiebold  Corn Stover removal  Cover crops
