What Makes "Organic Coffee" Organic?

Earlier I wondered what constituted an organic coffee. So I did some poking around and this is what I found. This is an excerpt from the article from the Organic Trade Association.

What is organic coffee?
Organic coffee is grown using methods and materials that have a low impact on the environment. Organic production systems replenish and maintain soil fertility, reduce the use of toxic and persistent pesticides and fertilizers, and build biologically diverse agriculture. Third-party certification organizations verify that organic farmers abide by the law.

What does it mean to be certified organic?
In order for coffee to be certified and sold as organic in the United States, it must be produced in accordance with U.S. standards for organic production and certified by an agency accredited by the U.S. Department of Agriculture. U.S. requirements for organic coffee production include farming without synthetic pesticides or other prohibited substances for three years and a sustainable crop rotation plan to prevent erosion, the depletion of soil nutrients, and control for pests.
