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.
