NuGIS data contributed to understanding the Lake Erie phosphorus situation

On the banks of the Maumee River in Ohio, Dr. Helen Jarvie of the Centre for Ecology and Hydrology in the UK explains how IPNI NuGIS data contributed to understanding the Lake Erie phosphorus situation. Loading to Lake Erie of dissolved phosphorus through tributaries like the Maumee has increased since the early 2000s, and the NuGIS nutrient balance data was helpful in confirming that the change was not due to overuse of fertilizer.

In her presentation to the 80 scientists attending the August 2017 SERA17 meeting, she explained how changes in tillage and fertilizer placement may have contributed to the issue, noting that 4R Nutrient Stewardship practices like timing and placement could be of value in mitigation.
