Gypsum And Elemental Sulphur: When And How Much? -

2010-12-6 · SS is 0.7 in the zero to six-inch depth which is equivalent to about 1.5 to 2.0 EC. Na and S are much higher in the six to 12-inch and 12 to 24-inch depths, so SS is likely quite a bit higher. The same issue of leaching salts is also relevant to the application of gypsum. The Ca from gypsum will replace Na and Mg but there has to be somewhere ...
