A pit lined with plastic and filled with bark on a Casco farm could have a positive impact on water quality in the area. Kinnard Farms is partnering with the Natural Resources Conservation Service and Department of Agriculture and Consumer Protection to build the state’s second bark bed tile filter. The bark in the pit acts as a filter for excess nitrogen and other nutrients as water from the tile line flows through it, similar to a wetland. Lee Kinnard says the years of data from a similar system in Sheboygan and others in the Corn Belt yielded positive results and hopes they can be duplicated locally.
Kinnard praised the Door-Kewaunee Demonstration Farm Network for bringing in experts and scientists to be great resources for their operations.
