About IPNI Canada

The agronomic programs of IPNI outside Canada ceased operations on April 1, 2019. This website remains online to provide a repository of past IPNI publications. Questions about past IPNI operations and projects can be forwarded to the International Fertilizer Association, The Fertilizer Institute, or Fertilizer Canada.



The International Plant Nutrition Institute (IPNI) from 2007 to 2019 was a not-for-profit, science-based organization dedicated to the responsible management of plant nutrition for the benefit of the human family.

Since July 2019, IPNI Canada has taken on a new role, providing scientific support to the nutrient stewardship initiatives of three industry associations: Fertilizer Canada, the Fertilizer Institute, and the International Fertilizer Association. It is also a partner in the African 4R Solution project.

IPNI Canada also serves as a repository of the historical legacy of past information products developed by IPNI, including Better Crops and Issue Reviews. Other items are available at the TFI Store.

IPNI Canada is governed by a board of directors and is managed administratively by Fertilizer Canada. Its Chief Scientist is Dr. Tom Bruulsema.

IPNI had active programs in Africa, Australia/New Zealand, Brazil, China, Eastern Europe/Central Asia and Middle East, Latin America-Southern Cone, Mexico and Central America, Northern Latin America, North America (Canada and U.S.A.), South Asia, and Southeast Asia. As a global organization, IPNI had initiatives addressing the world’s growing need for food, fuel, fiber, and feed. It also addressed widespread concern for issues such as food security and the relationship of crop production to the environment and ecosystems. Through cooperation and partnering with respected institutions around the world, IPNI added its strengths to agronomic research, education, demonstrations, training, and other endeavors. Best management practices for nutrient stewardship encouraged the 4R concept of applying the right source, at the right rate, at the right time, and in the right place.

Financial support for IPNI was provided by member companies dedicated to the efficient and responsible use of fertilizers in plant nutrition, companies producing one or more of the major plant nutrients (nitrogen, phosphate, potash, and sulfur) for agricultural purposes.
