What are your thoughts on putting down a "preventative" gypsum application for trees shrubs and turf areas near driveways, roads, and parking lots now before salt applications really get going?
Thanks, already have very low S and high metals so gypsum would be "perfect"If your SS is low, you may not have a huge problem though the Na can stick around for some time depending on the CEC and texture of the soil.
I would have to check some labeling and whatnot but I think 10-20 lbs gypsum per 1000 sqft would be on the lower/safer side. Just make sure you already dont have high S already.
