BIRMINGHAM, Ala., March 4, 2011 — PotashCorp, the world’s leading and largest fertilizer company by capacity, will increase its support of the Progressive Agriculture Safety Day® by 67 percent for 2011. The increased support will make possible one-day farm-and-ranch health and safety educational events, providing lessons designed specifically for rural youth.

“Safety and sustainability are among our company’s highest priorities – integrated in all aspects of our business,” explained Bill Doyle, President and CEO of PotashCorp. “Our support for the Safety Day program reflects these values and will teach rural youth how to work in a safe and sustainable way.”

PotashCorp has been a proud sponsor of the Safety Day program for the last 10 years. During that time, the company has contributed nearly $200,000, and made farm-and-ranch safety education possible for almost 14,000 children. Furthermore, these donations have helped the Progressive Agriculture Foundation (PAF) establish Safety Day events in rural communities and aided in the development of new safety lessons for the program.

Through donations from sponsors such as PotashCorp, the Progressive Agriculture Foundation is able to further efforts designed to keep rural children safe and healthy. The Foundation provides training and resources to help local community members conduct one-day safety and health programs that explore more than 30 topics. Since the program was founded in 1995, it has grown to become the largest rural safety and health educational program for youth in North America.

Potash Corporation of Saskatchewan Inc., is the world’s largest fertilizer enterprise by capacity, producing the three primary plant nutrients — potash (K), phosphate (P) and nitrogen (N) — and a leading supplier to three distinct market categories: agriculture, with the largest capacity in the world in potash, third largest in each of nitrogen and phosphate; animal nutrition, with the world’s largest capacity in phosphate feed ingredients; and industrial chemicals, as the largest global producer of industrial nitrogen products and the world’s largest capacity for production of purified industrial phosphoric acid. PotashCorp’s common
shares are listed on the Toronto Stock Exchange and the New York Stock Exchange.

The Progressive Agriculture Safety Day program is the largest rural safety and health education program for children in North America and a program of the Progressive Agriculture Foundation, a 501(c)(3) charitable foundation. The Foundation’s mission is to provide education and training to make farm, ranch and rural life safer and healthier for children and their communities. In 2008, PAF was awarded the Better Business Bureau Wise Giving Alliance National Charity Seal, demonstrating its commitment to accountability and ethical practices. Safety Day applications are due each July 15 for Safety Days that will be conducted the following calendar year.
