Government services
Block was a Republican whose agriculture successes formed the basis for his position as the Illinois Director of Agriculture. This led to him becoming the Secretary of Agriculture in President Ronald Reagan's administration. He was involved in the 1985 Farm Bill Act. Block was an Secretary of Agriculture, when more farmers lost their farms than at any time since the Great Depression of the 1930s. During his term as Secretary, a Federal court judge ruled in a due process decision, Coleman vs. Block, 663 FSupp 1315, 1332, that the U.S. Department of Agriculture and Farmers Home Administration were not giving farmers enough notice of alternative debt restructuring options. The Court ordered the USDA and FmHA to amend the forms issued to farmers. The decision eventually led to restructuring and reorganization of many farm debts. During the U.S. government's appeal of the decision, Congress passed the Agricultural Credit Act of 1987, Pub. L. No. 100-233, 101 Stat. 1568. Title VI of the Act made extensive changes in the statutory provisions which had formed the background for the Coleman litigation, the changes being designed to carry out the intent of the Coleman decisions. In June 1981, Secretary Block invited agricultural and educational leaders willing to work cooperatively toward the common goal of educating the public about the role of agriculture to a workshop in Washington, DC. The resulting task force recommended that the U.S. Department of Agriculture help coordinate local and state efforts. The was announced by Secretary of Agriculture John Block with a fanfare on Ag Day, March 21, 1983. The Declaration of Principle spelled out the purpose of the Agriculture in the Classroom program and featured the signatures of all seven living former Secretaries of Agriculture. There are now programs in every state and many U.S. Territories. Canada, with assistance from USDA, developed an program in every Province as well as a national organization. Countries around the world are interested in Agriculture in the Classroom because they have experienced the same needs in agricultural education.
