Causmag® Granomag® AL7 is an accurately sized granular reactive calcined magnesite with excellent flow properties and is fines-free to reduce dustiness in handling.
Granular (Coarse) Magnesium Oxide
Description
Uses
Causmag® Granomag® AL7 is mainly used in balanced fertilizer formulations and custom mixes as a slow release high grade magnesium source. AL7 is used for animal feed and as a rumen buffer in feed grain supplements. AL7 is used to supplement sheep and cattle diets where Magnesium levels may be low. Magnesium has a role in metabolism, formation of bone and teeth as well as maintenance of nervous function. AL7 is used extensively in Australian dairies, where mechanical feeding systems are preferred.
