International Joint Commission’s Report on Oversight of Animal Feeding Operations for Manure Management in the Great Lakes

Runoff from manure on agricultural fields—both surface and via field tiles—contributes significantly to nutrient loadings to the Great Lakes and is making the problem of harmful algal blooms more serious. This situation is exacerbated by increased frequency of extreme precipitation events which leads to increased runoff of excess nutrients from agricultural land.

Phosphorus removal structure construction and free P-TRAP application

Featuring Dr. Chad Penn and a team of engineers and technicians. P-TRAP is a free software developed by the USDA ARS allowing non-engineers to design and build P filters, which can significantly decrease phosphorus runoff from farm fields, reducing harmful surface water eutrophication and algal blooms, as demonstrated in this video. The video is being distributed to farmers and organizations across the United States by the US Department of Agriculture.

Summer road trip finds small streams have big impacts on Great Lakes

In the summer of 2018, Rob Mooney, a graduate student at the University of Wisconsin-Madison's Center for Limnology, set out on an epic road trip around Lake Michigan. Mooney was no stranger to the drive. In fact, he had already completed eight circuits of the lake over the previous two years as he monitored seasonal changes in dozens of rivers and streams flowing into the lake.

Phosphorus moves differently in Ontario versus Ohio 

By - John Greig, Country Guide - Canadian researchers have discovered that phosphorous in Ontario soils near the Great Lakes move through the soil in a different way compared to farms on the U.S. side. Now it’s a matter of looking at the best management practices for farmers on both sides of the border to help reduce phosphorous runoff.

Design for Riser Inlet Phosphorus Treatment System

The following report presents the design of a phosphorus treatment system for riser inlets used in agriculture. Riser inlets provide a direct route for agricultural surface water runoff to enter the tile drainage system, bypassing natural filtration barriers such as the soil
