Alan Haigh asked, "Does gypsum supply any magnesium as does dolomitic lime?"

Not likely or, at best, in trace amounts.

Alan, you have my curiosity..........................if your "sodic" soil is low in sodium, what other cation is present that causes the condition?
If you are ever tempted to use Greenstone, be warned that any amount more than a tiny bit may cause manganese toxicity.
