The state of Wisconsin is expanding farmland preservation agreements and increasing the tax credits. Farmland Preservation is a voluntary program that gives financial incentives for farmers to keep their land in production while preserving soil and water quality. Some of the new changes are that the time commitment to the program is shorter and the financial incentive is higher. Buffalo County dairy farmer Dustin Ellis had been toying with the idea of enrolling. He says now that the changes have been made, it's worth the paperwork.
