The International Plant Nutrition Institute has officially released the results of the 2015 North American Soil Test Summary. The summary is the most extensive evaluation of the fertility of North American soils ever conducted. It shows status and temporal trends for several critical nutrient and pH components of soil health and provides insights into the sustainability of farming practices.
For the first time, IPNI has released the results of these four most recent summaries within a web-based data analysis system found at http://soiltest.ipni.net. This website provides new opportunities to view, compare and contrast soil fertility data over this 15-year time period. The site also provides full access to a range of charts, maps, and tabular data sets, read more.
IPNI co-sponsored a symposium on N management, Metrics for Management of Sustainable Crop Nutrition, at the annual ASA, CSSA, SSSA meeting held in Minneapolis, MN.
Dr. Cliff Snyder, IPNI N program director, presided over the symposium. Presenters: IPNI directors, Dr. Tom Bruulsema and Dr. Rob Norton; Allison Thomson; Lara Moody; David Mulla; and Bruce Montgomery.

Dr. Fernando Garcia will host a free webinar on Wednesday, February 24. Garcia, director IPNI Latin America-Southern Cone, will discuss Looking for Sustainability: Long-Term Fertilization in the Pampas of Argentina. Click here to register. Can’t attend? We’ll post it later on our YouTube page.
This booklet is a practical guide to forage production developed by Dr. Don Ball, Dr. Carl Hoveland and Dr. Garry Lacefield, authors of the widely popular book Southern Forages – Modern Concepts for Forage Crop Management.
The 56 page Pocket Guide is packed with useful facts and reference lists related to plant characteristics, fertilizer and nutrients, stand establishment, animal requirements, grazing, and forage quality, including hay and silage. Visit our online store to purchase.
Are you a graduate student attending a degree-granting institution located in any country with an IPNI program? Candidates for either the M.S. or Ph.D. degrees, who are enrolled in a program of graduate study as of the application deadline, are eligible.
Priority will be given to the relevance of the proposed research in support of IPNI’s mission. Students in the disciplines of soil and plant sciences including agronomy, horticulture, ecology, soil fertility, soil chemistry, crop physiology, and other areas related to plant nutrition are encouraged to apply.

Congratulations to Dr. Cynthia Grant! Since 1986, Grant has worked as a research scientist at the Agriculture Canada Research Station in Brandon, Manitoba, Canada. Read more about her accomplishments and contributions to the field of plant nutrition here. For more information on IPNI Awards, visit our website.
In August I attended the Nutrient Reduction Strategy Field Day in Gilmore City, Iowa, USA. The next day I visited the 4R research site with Cliff Snyder, IPNI’s Nitrogen program director. The research site has 32 individually subsurface drained plots for subsurface drainage water quality evaluation. You can read more about the research project here.
