Abstract:Mark David - Professor in the Department of Natural Resources and Environmental Sciences in the College of Agricultural, Consumer, and Environmental Sciences at the University of Illinois. Illinois just finalized and released (summer 2015) a nutrient loss reduction strategy, led by IEPA and Illinois Dept. of Agriculture, that was developed with input from many groups (agricultural, environmental, point source, and university) during the past two years. This strategy is to lead to 45% reductions in nitrate and total phosphorus exported from the state by the major rivers (to help reduce the Gulf of Mexico hypoxic zone), as well as improve local water quality. About 80% of the nitrate and half the phosphorus in rivers of the state is from agriculture, with the rest from point sources. Both sources will need to make major changes to meet the goals of the strategy, which had an estimated cost of nearly one billion dollars per year for the next 20 years. In this presentation, Dr. David summarized where we are right now and what the plans are for implementing the strategy across Illinois, including a description of the many conservation methods available to reduce nutrient loss from agricultural fields.
