Lab studies about the disadvantages of dolomitic magnesium ignore the realities in the field
by KEITH REID
Just the other day, I had an email from an agronomist looking for information about magnesium, since there were salesmen in his area trying to sell calcitic lime, despite the fact that they were sitting next to a quarry producing high-quality dolomitic lime.
I was able to respond that there is no advantage to the calcitic lime, and that growers in his area should use the most economical source of lime.
Since trucking is the largest part of the cost of lime, this generally means the source closest to home.
