Widely used around farms and homesteads, this versatile powder serves various purposes to improve conditions for both plants and animals. In the garden, limestone powder works wonders as a soil amendment. When spread on the ground before planting, it absorbs and reduces acids in the soil, creating optimal growing conditions for plants. By neutralizing soil acidity, it enhances nutrient availability and promotes healthier plant growth, resulting in improved yields and overall garden success. As a moisture and odor absorbent, limestone powder is commonly utilized in barns and animal areas. By absorbing moisture and odors, it creates a more comfortable environment for both workers and animals, promoting overall well-being. Additionally, limestone powder can be beneficial for animal health. When fed to animals such as chickens, it helps increase calcium levels in eggshells, ensuring stronger and healthier eggs. Similarly, it can be given to cows to replenish calcium lost during the milking process, supporting their overall health and productivity. *Mesh size up to 300, Pale grey powder. Review: Great for treating poultry area - I researched the benefits of treated a poultry area to rid the area of disease- causing bacteria Review: Calcium supplement for me - I bought this as a calcium supplement for myself since it said it was suitable for chickens and cows. I take a little bit with grape juice (put the dry powder in my mouth and wash it down with the juice, being careful not to inhale before it’s all wet) and it’s a little fizzy and is reminiscent of grape soda, but not too much. Honestly, I noticed a difference right away, an exposed nerve in my mouth from a tooth that had broken partially off, stopped hurting and I can chew carefully on that side now. Very happy with this purchase. ## Features - 5 Pounds of Limestone Powder *Mesh size up to 300, Pale grey powder. - When spread on the ground before planting, it absorbs and reduces acids in the soil, creating optimal growing conditions for plants.
