Does Burlap Decompose? (Wood Prep Tips for Arborists)

Embracing Eco-Consciousness: Does Burlap Decompose? Wood Prep Tips for Arborists

As arborists and woodworking enthusiasts, we’re increasingly aware of our environmental footprint. The choices we make, from the tools we use to the materials we discard, have a direct impact on the health of our planet. That’s why the question of whether burlap decomposes is so crucial, especially when we’re dealing with wood preparation and tree care. Burlap, often used for wrapping root balls, protecting saplings, and even as a makeshift lumber cover, seems like a natural, eco-friendly option. But is it truly biodegradable? And if so, how can we optimize its decomposition while maximizing its utility in our wood processing endeavors? Let’s dive deep into the world of burlap, its composition, its decomposition process, and how we can use it responsibly in our arborist practices.

Understanding Burlap: A Natural Fiber’s Tale

Burlap, also known as hessian, is a woven fabric made from the skin of the jute plant or sisal fibers. Jute is primarily grown in India and Bangladesh, while sisal comes from the Agave sisalana plant, native to Mexico but now cultivated in many tropical countries. Both are bast fibers, meaning they are collected from the phloem or bast surrounding the stem of certain dicotyledonous plants. This makes them relatively strong and durable, ideal for various applications in agriculture, construction, and even fashion.

Composition and Properties:

• Jute Burlap: Primarily composed of cellulose (around 71%), lignin (around 13%), and hemicellulose (around 13%), with minor amounts of pectin, fat, and wax. Jute fibers are known for their high tensile strength, low extensibility, and good breathability.
• Sisal Burlap: Contains cellulose (approximately 65%), lignin (around 10-20%), and hemicellulose (around 10-15%). Sisal fibers are coarser than jute, making them more resistant to saltwater degradation, which is why they are often used in marine applications.

My Personal Experience:

I remember a time when I was working on a tree transplanting project. We had a large number of saplings to move, and we used burlap to wrap the root balls. It was a physically demanding task, but I appreciated the natural feel of the burlap against my skin. Knowing that it would eventually decompose gave me peace of mind, unlike using synthetic materials.

The Decomposition Process: How Burlap Returns to Earth

The biodegradability of burlap is one of its most appealing qualities. However, the speed and completeness of its decomposition depend on several factors.

Factors Influencing Decomposition:

• Soil Conditions: Warm, moist soil with a high microbial activity promotes faster decomposition. The presence of bacteria and fungi is essential for breaking down the cellulose and lignin in the burlap.
• Moisture Content: Adequate moisture is crucial for microbial activity. Burlap that is consistently wet will decompose faster than burlap that is dry.
• Temperature: Higher temperatures generally accelerate decomposition. The optimal temperature range for most soil microbes is between 70°F and 90°F (21°C and 32°C).
• Oxygen Availability: Aerobic decomposition, which requires oxygen, is the most efficient way for burlap to break down. Anaerobic decomposition, which occurs in the absence of oxygen, is much slower and can produce unpleasant odors.
• Burlap Treatment: Burlap treated with chemicals or dyes may take longer to decompose. Some treatments can inhibit microbial activity or make the fibers more resistant to breakdown.

The Science Behind the Breakdown:

The decomposition of burlap is primarily carried out by microorganisms, including bacteria and fungi. These organisms secrete enzymes that break down the complex carbohydrates (cellulose, hemicellulose) and lignin into simpler compounds.

1. Cellulose Degradation: Cellulase enzymes break down cellulose into glucose, which is then consumed by the microbes.
2. Lignin Degradation: Lignin is more difficult to break down than cellulose. It requires lignin-degrading enzymes produced by certain fungi, such as white-rot fungi.
3. Humification: As the burlap decomposes, it contributes to the formation of humus, a stable organic matter that improves soil structure and fertility.

Data Point:

According to a study published in the Journal of Environmental Quality, untreated burlap can decompose completely in soil within 6 to 12 months under optimal conditions. However, treated burlap may take significantly longer, potentially several years.

Burlap in Arboriculture: Applications and Best Practices

Burlap plays a vital role in various arborist activities, from protecting trees during transportation to preventing soil erosion. Understanding its applications and best practices can help us maximize its benefits while minimizing its environmental impact.

Common Uses:

• Root Ball Wrapping: Burlap is widely used to wrap the root balls of trees and shrubs during transplanting. It helps to retain moisture, protect the roots from damage, and prevent soil from crumbling.
• Tree Trunk Protection: Burlap can be wrapped around tree trunks to protect them from sunscald, frost cracks, and animal damage. This is particularly useful for young trees with thin bark.
• Erosion Control: Burlap sacks filled with soil can be used to create temporary barriers to prevent soil erosion on slopes and construction sites.
• Seed Germination: Burlap can be used as a cover for newly seeded areas to retain moisture and promote germination.
• Weed Control: Burlap can be laid around plants as a mulch to suppress weed growth.

Best Practices for Using Burlap:

• Choose Untreated Burlap: Opt for burlap that has not been treated with chemicals or dyes. Untreated burlap will decompose faster and will not contaminate the soil.
• Moisten Before Use: Wetting the burlap before wrapping a root ball or tree trunk can help it conform to the shape and retain moisture.
• Secure Properly: Use biodegradable twine or natural fiber rope to secure the burlap in place. Avoid using plastic ties or synthetic materials.
• Remove When Necessary: In some cases, it may be necessary to remove the burlap after a certain period. For example, burlap used to wrap a root ball should be loosened or removed once the tree has established itself in its new location.
• Compost After Use: Once the burlap is no longer needed, it can be composted. Cut it into smaller pieces to speed up the decomposition process.

Case Study:

I once worked on a project where we were transplanting a large number of mature trees. We used burlap to wrap the root balls, but we made sure to remove the burlap from the top of the root ball before planting. This allowed the roots to breathe and prevented the burlap from strangling the tree as it grew. We also made sure to use untreated burlap to avoid contaminating the soil.

Wood Preparation Tips for Arborists: Burlap’s Role

Burlap can be a valuable tool in wood preparation, offering protection and aiding in the seasoning process. Here’s how we can effectively integrate burlap into our wood processing routines:

Protecting Freshly Cut Lumber:

• Preventing Checks and Splits: When lumber is freshly cut, it’s highly susceptible to drying too quickly, which can lead to checks (small cracks) and splits. Covering the stack of lumber with burlap can help slow down the drying process, allowing the wood to dry more evenly.
• Sun and Wind Shielding: Direct sunlight and strong winds can exacerbate the drying process, causing uneven drying and warping. Burlap acts as a shield, protecting the lumber from these elements.

Seasoning Firewood:

• Initial Cover: While firewood needs airflow to season properly, an initial cover of burlap can protect it from heavy rain, which can leach out valuable resins and slow down the drying process.
• Windbreak: In particularly windy areas, burlap can be used as a temporary windbreak to prevent firewood from drying too quickly on the exposed sides.

Specific Techniques and Insights:

• The “Burlap Blanket” Method: For protecting lumber, I like to create a “burlap blanket” by stitching several pieces of burlap together. This allows me to cover the entire stack of lumber in one go. I ensure that the burlap is not in direct contact with the ground to prevent moisture wicking.
• Firewood Stacking with Burlap Accents: When stacking firewood, I sometimes use small pieces of burlap to cover the top layer, especially if I know there’s rain in the forecast. This is a simple way to protect the wood without completely blocking airflow.
• Moisture Monitoring: Regardless of whether I’m using burlap, I always use a moisture meter to monitor the drying process. This helps me determine when the lumber or firewood is ready for use.

Data-Backed Insights:

• Drying Time Reduction: Studies have shown that using a controlled drying method, such as covering lumber with burlap, can reduce the risk of defects by up to 50% and shorten the drying time by 20%.
• Fuel Value Preservation: Protecting firewood from rain can increase its fuel value by up to 15%, as the wood retains more of its volatile compounds.

My Personal Story:

I once made the mistake of leaving a stack of freshly cut walnut lumber exposed to the elements. Within a week, the boards had developed significant checks and splits. I learned my lesson the hard way and now always take the time to protect my lumber properly.
