The Fertilizer Institute (TFI), United States Department of Agriculture Natural Resources Conservation Service (USDA/NRCS), International Plant Nutrition Institute (IPNI), and Iowa State University (ISU) have worked together to bring expertise and coordinated outreach in an effort to help producers increase implementation of the 4Rs. Applying the right nutrient source, at the right rate, at the right time, in the right place is essential to nutrient stewardship and is the core of the 4Rs. To achieve this goal, this team of experts has created the following learning modules. An essential component of these learning modules is to provide information about the basic components of soil fertility and nutrient best management practices. Topics include an explanation of the key components of plant nutrition in relation to selection of fertilizer best management practices addressing the 4Rs. The modules address the macro- and micronutrients as well as soil sampling and integrated economic and environmental issues relative to nutrient management. Click Here
These modules provide information on nutrient management and practice implementation relative to the 4Rs. They are well suited for use by individuals interested in learning more about basic soil fertility and use of practices relative to source, rate, timing and placement. They will provide a good introduction to nutrient management for individuals working with growers as well as those stakeholders working in the area of environmental quality and related policy.

IPNI Educational Items
The International Plant Nutrition Institute (IPNI) has multiple 4R nutrient stewardship educational items available on www.ipni.net.
Two videos were produced in 2010 to introduce the 4R nutrient stewardship message ("The Right Way to Grow...4R Nutrient Stewardship") and to address 4R nutrient stewardship relative to wheat production (“The Right Way to Grow Wheat...4R Nutrient Stewardship"). The videos can be viewed for free by visiting the IPNI website at: http://www.ipni.net/video.
Additionally, IPNI developed a set of articles during 2009 under the theme of "Know Your Fertilizer Rights" which appeared in Crops & Soils magazine, a publication of the American Society of Agronomy. The articles focus on the concepts behind fertilizer best management practices and increasing understanding of 4R nutrient stewardship. The 4Rs refer to using the right fertilizer source, at the right rate, right time, and right place. The articles are authored by scientific staff of IPNI in cooperation with university and industry colleagues. The primary audience of the publication is Certified Crop Advisers (CCAs). Each article is board-approved for self-study and is accompanied by a quiz, so CCAs may earn continuing education units (CEUs). The articles are available at http://www.ipni.net/4r.
CFI Grow Zone
GrowZone was developed by the Canadian Fertilizer Institute to provide continuing education to fertilizer industry workers. Modules currently include training for drivers and managers on driver fatigue management, an ammonium nitrate safety course, a NERP training program and a 4R Nutrient Stewardship Online Training course. New training courses will continue to be added. Our goal is provide formal training, and to be seen as a guide, an informer, and a reference to you and all your Canadian fertilizer needs. The courses are free to take, however, for some there may be a charge to take the quiz and obtain a certificate. To learn more, visit http://growzone.cfi.ca/.
Certified Crop Advisors Webinar Series
The 4R Approach to Soil and Water Quality combines the science of plant nutrition and soil fertility with a practical knowledge and application to successfully manage crop nutrients. The course is a non-credit course taught online using distance education technologies. All lectures are recorded and posted to the class website to be viewed at a later time if you are not able to take part in the live lecture. Quizzes will be due by the Tuesday following the next class (or 12 days later). There are no minimum requirements needed to register for this course. Students who complete all eight quizzes can request a certificate of completion for this course. To learn more, visit https://www.agronomy.org/education/4r-approach.
