The Wisconsin Farm Bureau Federation disagrees with the
conclusions of the report. According to Paul Zimmerman,
Executive Director of Governmental Relations for the WFBF,
farmers have improved soil conservation over the last two
decades to make sure more dirt remains in place. Zimmerman
blames dams that have made lakes more stagnant for some of the
problem. Carpenter's study concludes with a call for the use of
various technologies to reduce or eliminate the problem.
Suggestions included manure digesters to create sludge that
could be sent to landfills, buffer strips to filter field runoff
and the incorporation of new technologies to remove phosphorus
from the soil.
