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.
The online learning modules based on practices used to implement 4R nutrient stewardship are now available online at http://www.nutrientstewardship.com/4r-training/training-modules. The modules consist of chapters with downloadable content and narrated slides that cover information on nutrient management and practice implementation relative to the 4Rs.
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.
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.
