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.
