Calcium carbonate limestone powder is a widely diverse product and is commonly used around farms and homesteads for a variety of uses. As a moisture and odor absorbent, it is used in barns and animal areas to create more favorable conditions for both workers and animals. It can also be fed to animals such as chickens to increase calcium in eggshells and to cows to replace calcium lost during the milking process. This neutralizer powder can be spread on the ground before planting to help absorb and reduce acids in the soil, creating better growing conditions for your plants.
