From: Joe Hecksel Chemical ammendments like gypsum and limestone displace the sodium and potassium ions with calcium ions.
Thanks much Joe for your explanations.
I have been considering amending my clay hill apple orchard with gypsum but wonder how to apply it. Considering clay's nature I would think that a surface application, say a ton per acre, would never get down into the clay to do its work. I would think it would have to be worked down deep with heavy equipment prior to planting. Can surface application work?
Secondly, during the last Nafex conference a knowledgeable grower strongly recommended cobalt as the solution to breaking up clay. I have no idea what level of application, and would not want to over appply. Does it work with ions as well, or some other mechanism?
Del
