What is Barn Lime?

Barn lime is crushed up limestone – also known as Calcium Carbonate. It’s used to prevent the smell of ammonia build-up and odors in barns and stalls. Ammonia comes from the urea in livestock waste when it’s left sitting and not cleaned up. Ammonia can cause a variety of problems for your livestock, such as thrush, respiratory issues and immune system issues. Barn lime can help keep animal pens, barn floors and gutters all clean, dry and sweet.

When to Use Barn Lime

It’s important to keep your stalls clean in the first place. While barn lime can help with ammonia odors, it’s best to clean your stalls on a regular basis. Damp, odorous conditions are an invitation for flies and other pests. Clearing out animal droppings, manure, wet bedding and damp hay can help with fly control on the farm. Read through our tips for more ways to control flies around your livestock.

There are other ways to reduce ammonia levels in your livestock stalls. Keeping your barn well-ventilated, either by using barn fans or a ventilation system, can keep air moving. Rubber stall mats are another way to keep your stalls clean. They’re easy to clean and can help reduce the smell of ammonia.

Barn lime is an inexpensive solution to hide ammonia odors in your stalls. For more tips on caring for your barn and livestock, visit our Hobby Farming blog.
