New program pays up to 90 percent of land value.Under the program, landowners enroll land in the federal Conservation Reserve Program for 15 years. But they also sign up for the Reinvest in Minnesota program, and agree to a permanent easement, a legal document stipulating the land must always be managed for conservation.The federal program protects land for 10 or 15 years, opening the door for the land to be plowed under again. Minnesota could lose 500,000 acres of grassland in the next five years.It's critical to preserve land permanently to maximize water quality protection, said Aaron Larsen, a program manager for the West Otter Tail Soil and Water Conservation District. The Westbys get annual CRP payments for 15 years for taking this farmland out of production. They also get a one-time payment from the state.The payments are determined through a complex formula, but the combination of federal and state dollars will equal 90 percent of the average per acre land value.The goal of the Conservation Reserve Enhancement Program is to restore and preserve 60,000 acres, or roughly 90 square miles of land across 54 counties in western and southern Minnesota.
