The Fertiliser Institute

The concept of implementing BMPs began almost 20 years ago with research and testing by the Potash and Phosphate Institute (PPI) which has recently been integrated with the Potash and Phosphate Institute of Canada to form the International Plant Nutrition Institute (IPNI), with the objective being to develop techniques and methods that provide adequate nutrition for crops, while minimizing nutrient losses and their impact on the environment. More recently, promoting the use of the right fertilizer product at the right rate, right time and right place, which is commonly referred to by the fertilizer industry as the 4 Rs paradigm, has become the cornerstone for communicating about BMPs with farmer customers in the United States and abroad.
