The implementation of woodchip bioreactors continues to happen at a slower pace than other conservation practices that reduce nitrate loss. Most of the bioreactors were implemented for research and demonstration purposes. For this reporting period, five new woodchip bioreactors were implemented, treating a combined area of 115 acres. In 2016, there were 20 known bioreactors treating approximately 611 acres of tiled cropland. The 2019 Biennial Report showed an increase of 17 bioreactors between 2016 and 2018, treating approximately 1,345 acres. By the end of 2020, there were a total of 42 known woodchip bioreactors treating approximately 1,460 acres.
