CaC03 = calcium carbonate MgC03= Magnisium Carbonate.

It looks like Dolomitic Limestone Owem. Used to raise soil pH. The amount needed depends on your soils CEC & current pH. Have you done a soil test?

Yes I had one done Steve. I am at work and do not have it with me. It is not nearly as thorough of a test as you guys in the states got, but I will post what they told me after I get home. thanks, owen

Hey Owen that stuff is a low magnesiumm dolomite. It can be used at the same rate as lime in order to improve pH and rise calcium levels, it will work slow and have small effect on magnesium as it content is low. A high magnesium dolomite (The one I used every year) can be up to 30% MgCO3.
I used at a rate of 2000 Kg/Ha. I have already spread it and tilled under, just 3 days ago.
If your pH is over 7, do not use it.

Good luck.......................Carlos

Well, I checked for the test results during lunch, and I can't find them. At any rate, I remember the pH as being 6.4, they didn't give a CEC. At the time (Mid-January) I thought that 6.4 would be okay. The rest of the results were simply put as "very high to low". As I recall the N was "very high", the P was "normal" the K was "high" and the OM was "low". What do you think?

If you're able to till 100 lbs of lime (per 1000 sq ft) into the top 8-12" of pH 6.4 soil, you're doing fine. High or low Mg is of little concern unless the Mg is already a problem one way or the other. I'd use it.

Well I decided to do a little googling now that I am dangerous and armed with a little bit of knowledge from you guys. I found this informative article on growing giant pumpkins and the use of Dolomitic Limestone. Thanks Glenn, Steve and Carlos for your help.

Geeze, that was an excellent article. It will get printed and be inserted into my binder for reference.
