The producers received the prestigious River Friendly Farmer conservation award during ceremonies at the Indiana State Fair.
The award is sponsored by the Indiana Association of Soil and Water Conservation Districts (IASWCD) and Indiana Farm Bureau, Inc.
"We have an impressive group of recipients this year," IASWCD President Ray McCormick said. "The conservation practices these farmers use improve soil health on their farms not just for themselves but for future generations.
"Our River Friendly Farmer winners know soil is a complex living ecosystem and we all have an obligation to sustain and improve it. That's what they are doing to conserve our natural resources every day."
Two Clay County farmers, Joe Edwards and Tim Stearley, were among those honored.
The 2012 River Friendly Farmer recipients represent grain, livestock and poultry producers from watersheds in 40 Indiana counties.
They join an elite group of 600 winners since the award was first given in 2000 to Hoosier farmers who use exceptional conservation practices to improve soil health and protect water quality.
Additional sponsors of the award include the Indiana State Department of Agriculture Division of Soil Conservation and the USDA Natural Resources Conservation Service.
Recipients were honored by Lt. Gov. Becky Skillman and Indiana Farm Bureau President Don Vilwock.
Also on hand for the ceremony was USDA NRCS State Conservationist Jane Hardisty and President Abraham Lincoln, portrayed by Wilbur Tague of Brownsburg, who helped celebrate the USDA's 150th anniversary.
