TYPE: Natural Dolomitic Lime with high Magnesium Content and low Calcium content
BEST SOIL:  Sandy or lighter soils that are low in Magnesium in need of an increased pH adjustment
BEST CROP: Potato, Corn, Soy Bean, Wheat
BENEFIT: Effective neutralizer, slower release for in lighter soils, bulk powder, cost-effective.


GLC Minerals’ InstaLime is a custom-processed dolomitic aglime from a natural source. This naturally occurring mineral is ground to a fine powder to make it more effective than dolomitic aglime. It also has a higher acid neutralizing potential than calcitic lime (thus giving it a higher Calcium Carbonate Equivalent ). In addition, the soil reaction rate of dolomitic limestone is known to be 2.5 to 4.5 times slower than calcitic lime.

Because InstaLime is slower reacting than calcitic lime, InstaLime is the perfect choice to increase pH, protect humus and supply Mg on lighter soils like sandy loams, sandy soils, forest soils and pastures. GLC Minerals’ InstaLime is the perfect choice to efficiently and effectively increase soil pH in the central sands of Wisconsin and protect crops from herbicide injury that is often associated with over-liming when using calcitic aglime.

Because InstaLime is a bulk powder product, it’s more cost effective than pelletized products. The pelletizing process adds considerable cost to the product without any improved effectiveness. In fact, purchasing pelletized products may make soil correction cost prohibitive.

For optimum yields, effective liming material must raise the soil pH to a desired level. InstaLime custom processed lime from GLC Minerals does just that, with the smallest amount of material applied possible. In contrast, aglime must be applied farther in advance and at much higher rates per acre than InstaLime. In some cases, poor quality aglime may not increase soil pH to the desired level.
