Basic, Intermediate and Advanced Phosphorus Applications

Basic, Intermediate and Advanced Phosphorus Applications

New research from IPNI and TFI helps define a precision approach to P applications on major commodity crops in North America

The 4Rs of Nutrient Stewardship are defined in terms of making a cropping system more sustainable, with the “right” source, rate, time and place subjective to the factors of each farm and field. And the site-specific nature of the 4R practices means recommendations differ for each field, but there are best practices that can be implemented to manage phosphorus (P) loss.

The International Plant Nutrition Institute (IPNI) and The Fertilizer Institute (TFI) recently sponsored a science workshop in collaboration with the Field to Market® Alliance for Sustainable Agriculture to review a science-based approach for five major commodity crops produced in North America.

Researchers analyzed prescriptive solutions to determine a more precise application of the right source, rate, time and place of phosphorus. While phosphorus supports high-yield crops, it also is at an elevated risk of being lost to the environment. Findings from the research outlined basic, intermediate and advanced practices for more productive phosphorus applications.

Findings from this workshop, such as how to quantify P loss and adaptive management strategies, as well as other crop and soil management practices from the IPNI, can be found here: http://www.ipni.net

The sustainable farming definition has to do with a lot more than just crops. It is the act of sustainable agriculture. It utilizes ecological cycles in a way that is sensitive to the environment and the plant life within it. Sustainable farming practices promote environmentally friendly methods that protect the land and support the ecosystem […]

In a recent article in CropLife (May 11), Eric Sfiligoj discussed the development of “renewable diesel” and how its production into the foreseeable future may result in the vast majority of soybeans produced in the United States going to support this new fuel.  (Sfiligoj wasn’t alone. AgWeb’s Chip Flory recently noted that some estimates place […]
