Using biochar in animal stalls can improve air quality, reduce ammonia, and enhance animal health by absorbing odors and moisture. Biochar can also be used to improve soil health in pastures and other areas on the farm.
What is Biochar
Biochar is a carbon-rich solid material produced by heating biomass (like wood, crop residues, or manure) in a low-oxygen environment through a process called pyrolysis. It’s essentially a form of charcoal that’s designed to be used as a soil amendment and for other applications like water treatment and carbon sequestration.
Pyrolysis Process
Biochar is created through pyrolysis, a process where biomass is heated in the absence or with limited oxygen. This process converts the carbon in the biomass into a stable, long-lasting form. Pyrolysis also helps to destroy any pathogens or harmful substances that might be present in the biomass.
Composition and Properties
Biochar is primarily composed of carbon (about 70% or more). It is black, lightweight, fine-grained, and has a large surface area. This porous structure gives biochar a high ability to retain water and nutrients, making it beneficial for soil health.
Benefits of Using Biochar in Animal Stalls
Odor and Ammonia Reduction:
Biochar’s porous structure effectively absorbs ammonia and other odorous gases, leading to a cleaner and more pleasant environment for animals.
Improved Animal Health:
Reduced ammonia exposure can minimize respiratory issues in animals. Fewer flies and pathogens are also associated with biochar use, contributing to better overall animal health.
Moisture Management:
Biochar can help absorb excess moisture in stalls, reducing the risk of muddy conditions and improving animal comfort.
Soil Health Enhancement:
Biochar can be added to manure and then applied to pastures or other areas, improving soil structure, water retention, and nutrient availability.
Carbon Sequestration:
Biochar helps to sequester carbon, contributing to climate change mitigation.
How to Use Biochar in Animal Stalls
Bedding:
Biochar can be used as part of the bedding material in stalls, either mixed with other bedding materials like straw or sawdust.
Application to Manure:
Biochar can be added to manure in the stalls to capture nitrogen and improve its quality.
Acidification:
According to the US Biochar Initiative, biochar can be acidified to increase its ability to capture nitrogen.
