Why Are Cooperatives Organized?

• Strengthen bargaining power
• Maintain access to competitive markets
• Capitalize on new market opportunities

• Manage risk

What Are Farmer Cooperatives?

In agriculture, there are nearly 3,000 farmer cooperatives whose members include a majority of our nation's 2 million farmers and ranchers. These include:

• Marketing cooperatives - which handle, process and market virtually every commodity grown and produced in the United States.
• Bargaining cooperatives - which bargain to help their farmer members obtain reasonable prices for the commodities they produce.
• Farm supply cooperatives - those engaged in the manufacture, sale and/or distribution of farm supplies and inputs, as well as energy-related products, including ethanol and biodiesel.
• Credit cooperatives - include the banks and associations of the cooperative Farm Credit System that provide farmers and their cooperatives with a competitive source of credit and other financial services, including export financing.

How is this different from collective bargaining!
