Estimating annual chloride use in Minnesota
By Alycia Overbo and Sara Heger, Water Resources Center
Salt is used every day in many applications.  People add salt to food, apply salt to pavement and roads after snowfall, and use salt in their water softeners.  While salt is inexpensive to purchase, it can have a high environmental cost, as elevated chloride levels are toxic to many plant and aquatic species.  The most commonly used salts contain chloride and research has shown that chloride levels are increasing in rivers, lakes, streams, and groundwater across North America.

Citizen science at work: an easy way to report invasive species
By Megan M. Weber, Aquatic Invasive Species Extension Educator
Have you noticed an invasive species in or near your favorite water body? Reporting invasive species (both aquatic and terrestrial) has gotten even easier with the Great Lakes Early Detection Network (GLEDN) app. You can use GLEDN to report new sightings, learn identification tips, and view distribution maps of invasive species. This app provides an excellent opportunity for anyone to contribute to the invasive species distribution dataset in Minnesota and beyond.

Effects of liquid manure injection into a winter rye cover crop: on-farm trials
Leslie A Everett, Randy Pepin, Jeffrey A Coulter, and Melissa L Wilson
Nitrate levels above the drinking water standard of 10 ppm are frequently found in subsurface drainage tile water or groundwater below farm fields of the upper Midwest. Nitrogen comes from applied manure and fertilizer, along with natural mineralization of organic matter.

Soil conservation took Les Everett across the world but also keeps him down on the farm
Even as a 4Her growing up on the family farm in Iowa, young Les Everett was looking for ways to improve soil health and the environment. One of his 4H projects showed the importance of check dams in slowing down water flow and the accompanying soil erosion. Eventually those interests brought him to the Water Resources Center, where after 23 years of work he retired from this past May.

Getting involved in aquatic invasive species: something for everyone
By Megan M. Weber, Aquatic Invasive Species Extension Educator
Whether you are looking for a quick day of learning and action or opportunities for advanced learning and volunteer service, we have the program for you to get involved in Minnesota’s response to aquatic invasive species (AIS). Read more about the AIS volunteer and citizen science programs developed by the Minnesota Aquatic Invasive Species Research Center and University of Minnesota Extension.

Anna Cates announced as state soil health specialist
The Minnesota Office for Soil Health (MOSH) -- a collaboration of the Board of Water and Soil Resources (BWSR) and the U of MN Water Resources Center (WRC) -- is pleased to welcome Anna Cates as the new State Soil Health Specialist. Anna is just finishing her PhD in Agronomy from the University of Wisconsin-Madison where she has been studying soil carbon cycling in corn-cover crop biofuel systems.
