Needless to say, I am glad I sent more samples off to A&L Eastern. The WVU results aren't much to talk about:
pH: 6.6 P: 100 K: 203 Ca: 2585 Mg: 820 OM: NOT LISTED Zn: NOT LISTED Cu: NOT LISTED Mn: NOT LISTED
K: 0.3 (MEQ/100 G) Ca: 6.5 (MEQ/100 G) Mg: 3.4 (MEQ/100 G) H: 0 % SAT: K=3 Ca=64 Mg=34 H=0 CEC: 10 BS: 101
The dolomitic lime I added this spring has driven the Mg thru the roof! I am going to wait until I get the A&L lab reports back before I do anything. Until then I am considering a calcitic lime at about 30 lbs/1000 sqft. And dose of gypsum.

No more dolomite.
Calcitic Lime Gyspum Sulfate of Potash &/or old rotten horse poop.

Here are the results of the area surrounding the patch. Which will actually be supporting two plants. This is basically what my garden soil was like before anything was done to it. pH: 4.9 P: 55 K: 190 Ca: 1054 Mg: 122 OM: NOT LISTED Zn: NOT LISTED Cu: NOT LISTED Mn: NOT LISTED
K: 0.2 (MEQ/100 G) Ca: 2.6 (MEQ/100 G) Mg: 0.5 (MEQ/100 G) H: 9.8 % SAT: K=2 Ca=20 Mg=4 H=74 CEC: 13 BS: 26
A couple of things of interest here, maybe you could explain them for me Steve: Note the drop in CEC. This is a clay based soil. Could this drop be due to the Ca:Mg ratio? Also note the H levels. 0.0/0 in the amended soil, 9.8/74 in the field. Does this make any sense? I am assuming it is because the pH is nearing neutral. Lastly, what is BS? (other than an abreviation cow manure that is...lol).

BS = Base Saturation. This is the measure of the cation nutrients on the exchange sites.
Potassium (K20), Calcium (Ca), Magnesium (Mg) & Hydrogen (H) are the cation elements. As Calium goes up, the other cation elements drop in percentage. Therefore the BS% will always end up around 100%.
The second test still demonstrates high magnesium considering the amount of liming materials needed. Use Calcitic Limestone (75%) to 25% Domonitic or the Magnesium levels are going to skyrocket.
You're going to need some potash there too.
