UltraMag is a high magnesium soil amendment. Formulated as a fine powder for bulk broadcast application, UltraMag absorbs quickly to restore balance in the soil pH and infuses beneficial magnesium. This magnesium soil amendment provides long-lasting soil benefits, making it cost effective for managing soil pH for multiple seasons.
Calcium Magnesium Carbonate - CaMg(CO3)2
Corn, alfalfa and other vegetable crops.
Acidic soil lacking magnesium
Fast-acting pH neutralizer with soluble magnesium.
Naturally-Mined Dolomitic Limestone Soil Amendment
Average Chemical Analysis
| Chemical Compound | % of Product | |
|---|---|---|

How Does a Dolomite Lime Application Work to Balance pH?
With the chemical composition of dolomite lime, pH levels are naturally raised. UltraMag features:
- Calcium Carbonate Equivalent (CCE) of 102*
- Fineness Factor of 99.8**
- Neutralizing Index of 102***
- *Determined by laboratory tests
- **Fineness Index = 20% x (% of particles between 20 & 8 mesh) + 60% x (% particles between 60 & 20) + 100% x (% of particles passing 60% mesh)
- ***Neutralizing Index = Fineness Factor x (%CCE/100)
Typical Particle Size Distribution
| U.S. Mesh Screen | % Retained | % Passed |
|---|---|---|
| 8 | 0 | 100 |
| 20 | 0.5 | 99.5 |
| 60 | 3 | 96.5 |
| Pan | 96.5 | 0 |
Increase Yield for Corn, Alfalfa and Other Vegetables
Light, sandy soil doesn’t retain water or nutrients well and may not provide adequate physical support needed to grow corn, alfalfa and other vegetables. Soil chemistry is improved with this magnesium soil additive to promote a healthy harvest.
