There are several practices ag retailers and farmers can implement on fields to reduce nitrogen runoff. Woodchip bioreactors, or woodchips buried in tiled trenches, is one practice that has proven to keep nitrogen on fields and out of waterways. Microorganisms attach to the woodchips, taking up nitrates from water, and then expel the nitrates as a gas that is released into the atmosphere, instead of runoff into surface waters. In addition, planting trees with a few feet of buffer between the field edge and tree line reduces nitrogen loss and limits yield loss. Read the full article here!
