The Indiana State Department of Agriculture (ISDA) is leading a nationwide effort asking the U.S. Postal Service to issue a soil health forever stamp and is looking for public support. People can participate by signing on to a Soil Health Forever letter, available online, or sending a personal letter of support to ISDA at One North Capitol, Suite 600, Indianapolis, IN 46204, or e-mail it to firstname.lastname@example.org. The letter must be addressed to the "Citizens' Stamp Advisory Committee." To be included in the proposal, all signatures and/or letters of support must be received by July 23, 2018.
