The first hint for your group project.

On most Vermont dairy farms purchased feed was the largest import of P; fertilizer was the largest on others.

(several studies have been conducted that indicate this (the results from one are available here), don't get lost in the details; take a look at slides 17 and 18 for important clues)

Group Project Jumpstart and Water Conservation

Today:

1. Extra Credit Quiz:
1. What were the three general categories of sources of phosphorus in Lake Champlain?
2. How does excess phosphorus in the Lake cause problems?
   
   
2. Group Project Jump-start: Groups met to discuss their plan of attack, identify a blogger, and identify speakers for the final presentation. Project description is linked under Course Documents. I have already sent invites to each of the group bloggers. At our next class meeting, please let me know if you did not receive your invite.
   
   
3. Water Conservation: In the same groups for the project students discussed personal water conservation possibilities. We have completed 3 recent case studies (Aswan Dam, Hole in the Donut, and Lake Champlain) involving water. The goal of today's exercise was to demonstrate how small decisions can make a big difference in water conservation efforts.
