In Montana and elsewhere in the western United States and Canada, acidity is a problem that is affecting soil quality and the environmental, economic, and social sustainability of agriculture production systems. Watch our video, Acidification of Cropland Soil: Impact, Causes, and Solutions, for an overview of the issue and MSU suggested actions:



Soil pH test results reveal that Montana's agricultural fields are becoming more acidic.
