Subject: Re:Re: Re: Gypsum jar test

Little River, TX

It is more like one cation displacing a weaker cation that is bonded at one of the many zillion clay sites.

This is where my geriatric chemistry has it's limitations. Calcium and Magnesium have about the same electron charge. I believe Calcium has a stronger charge than sodium so it is easier to displace sodium on the CEC sites with Gypsum.

The sulfur is the anion that the displaced cation will attach to. If the resulting molecule is water soluble than it will leach as away if the soil structure is amiable.

Am I getting closer ?
