Sulphur stones isolated

eKonomics News Team

If you have been paying attention the last few years, there are more and more reports of sulfur response across a broad range of crops throughout North America. In fact, we have been highlighting some of that research on the eKonomics site (Iowa, Midwest, Western Canada). One specific piece we have not highlighted is sulfur recommendations based upon state/province and crop. To address that, below are the recommendations for various crops in specific states/provinces. The rates provided are not to be applied universally within the geography listed; universities/governmental entities provide additional guidelines associated with these rates. If you want more information about the guidelines, please follow the links to the published university/governmental documents.
