June 26, 2015 – Peachtree Corners, GA, USA – The International Plant Nutrition Institute (IPNI) has appointed Dr. Tom Bruulsema as its Phosphorus Program Director. “This change in focus reflects a need to devote greater attention to phosphorus, its role in global food security, and its potential for unintended envi- ronmental impacts,” explained IPNI President Dr. Terry L. Roberts. “Tom has been directing IPNI programs in the Northeast for 21 years and will continue his involvement and leadership on 4R nutrient stewardship and sustainability issues,” said Roberts.

All IPNI scientists’ activities include agronomic programs that address phosphorus, nitrogen, potassium and other plant nutrients, and 4R Nutrient Stewardship is a strategic component of the Institute’s regional and global tactical plans. Having a Phosphorus Program Director will provide a point person to lead the Institute’s ongoing efforts in ensuring phosphorus is used effectively and efficiently.

Dr. Bruulsema has been recognized as a Fellow of the American Society of Agronomy, the Soil Science Society of America, and the Canadian Society of Agronomy. He will continue to be based in Guelph, Ontario, Canada.
