Benefits of Composting

Composting offers multiple advantages for Ontario residents and the environment. This practice enhances soil quality, reduces waste in landfills, and supports sustainable gardening efforts.

Environmental Impact

Composting significantly reduces greenhouse gas emissions from landfills. When organic waste decomposes in anaerobic conditions, it produces methane, a potent greenhouse gas. By composting, Ontario residents divert organic materials from landfills, mitigating this environmental concern.

Compost also acts as a natural carbon sink. It sequesters carbon in the soil, helping to combat climate change. Additionally, composting conserves water by improving soil structure and water retention capacity.

The process supports local ecosystems by providing nutrients for plants and beneficial organisms. It creates a healthier soil food web, promoting biodiversity in gardens and landscapes.

Advantages for Soil Quality

Compost serves as an excellent soil conditioner. It improves soil structure, making it more porous and less compacted. This enhanced structure allows for better root growth and increased water retention.

The nutrient-rich compost feeds plants slowly and steadily. It contains essential macronutrients and micronutrients that promote healthy plant growth. Compost also helps balance soil pH, creating optimal conditions for plant development.

Soil amended with compost shows increased resistance to erosion. The improved structure helps soil particles bind together, reducing runoff and nutrient loss during heavy rains or irrigation.

Reducing Waste and Recycling Efforts

Composting is a key component of Ontario’s waste reduction strategy. It diverts a significant portion of organic waste from landfills, extending their lifespan and reducing the need for new disposal sites.

By composting, residents actively participate in the circular economy. Kitchen scraps and yard waste transform into valuable resources for gardens and farms. This process closes the loop on organic waste recycling.

Composting at home reduces the energy and resources needed for waste collection and transportation. It decreases the burden on municipal waste management systems and lowers associated costs.

Understanding Compost Materials

Successful composting requires a balanced mix of materials rich in carbon and nitrogen. Knowing which items to include and avoid is crucial for creating nutrient-rich compost.

Balancing Greens and Browns

Greens provide nitrogen and browns supply carbon, both essential for effective composting. Greens include food waste, grass clippings, and coffee grounds. Browns consist of dry leaves, twigs, wood chips, and shredded newspaper. Aim for a ratio of 3 parts browns to 1 part greens by volume.

Mix greens and browns thoroughly to ensure proper decomposition. Add greens in thin layers to prevent odors. Incorporate browns to maintain airflow and absorb excess moisture.

Greens:

• Food scraps (fruits, vegetables)
• Coffee grounds
• Fresh grass clippings

Browns:

• Dry leaves
• Shredded newspaper
• Wood chips
• Twigs

Items to Avoid in Your Compost

Certain materials can harm your compost or attract pests. Avoid adding meat, dairy products, and oily foods, as they may create odors and attract unwanted animals. Diseased plants, pet waste, and chemically treated materials should also be excluded.

Do not include:

• Meat and fish scraps
• Dairy products
• Oils and fats
• Diseased plants
• Pet waste
• Chemically treated wood

Pesticide-treated yard waste may introduce harmful chemicals to your compost. Instead, use organic gardening methods to ensure safe, chemical-free compost materials.

Setting Up Your Composting System

Creating an efficient composting system requires careful planning and preparation. Key factors include choosing the right bin, finding an ideal location, and maintaining optimal conditions for decomposition.

Selecting a Compost Bin

Compost bins come in various sizes and styles to suit different needs. Store-bought bins offer convenience, while DIY options provide flexibility. Plastic bins with lids are popular for their durability and pest resistance. Wooden bins blend well with landscaping but may require more maintenance. Wire mesh bins are inexpensive and allow good airflow.

For small spaces, consider compact tumbling bins that are easy to turn. Larger yards can accommodate stationary bins or multi-bin systems for continuous composting. Choose a size that matches your expected organic waste volume and available space.

Ensure the bin has adequate ventilation holes for air circulation and drainage holes at the bottom to prevent waterlogging.

Location and Setup Tips

Place your compost bin in a level, well-drained area with partial sun exposure. This promotes decomposition while preventing excessive moisture buildup. Avoid low-lying areas prone to flooding.

Position the bin for easy access from your kitchen and garden. A spot near a water source is helpful for maintaining proper moisture levels.

Clear the ground beneath the bin and add a layer of coarse material like twigs or straw for drainage. This also encourages beneficial organisms to enter the pile.

Set up your bin on bare soil rather than concrete to allow worms and microorganisms to access the compost. If using a paved surface is unavoidable, add a layer of soil at the bottom of the bin.

Maintaining Proper Conditions

Successful composting depends on balancing four key elements: carbon, nitrogen, oxygen, and moisture. Aim for a mix of 3 parts “brown” materials (carbon-rich) to 1 part “green” materials (nitrogen-rich).

Brown materials include:

• Dry leaves
• Straw
• Shredded paper

Green materials include:

• Fruit and vegetable scraps
• Coffee grounds
• Fresh grass clippings

Keep the compost moist but not waterlogged. It should feel like a wrung-out sponge. Add water during dry periods or cover the pile during heavy rains.

Turn the compost every 1-2 weeks to aerate it and speed up decomposition. Use a garden fork or compost aerator tool to mix materials thoroughly.

Monitor the temperature. A warm compost pile (130-150°F) indicates active decomposition. If it’s too cool, add more green materials and turn the pile.

The Composting Process

Composting transforms organic waste into nutrient-rich soil through a series of biological processes. Microorganisms break down materials in stages, requiring proper aeration and moisture control for optimal results.

Stages of Decomposition

The composting process unfolds in distinct phases. Initially, mesophilic bacteria thrive, breaking down simple compounds. As temperatures rise, thermophilic bacteria take over, decomposing more complex materials. This hot composting stage can reach up to 160°F (71°C).

As the pile cools, fungi and actinomycetes continue the breakdown. Finally, the compost enters the curing phase, where it stabilizes and matures.

Each stage plays a crucial role in creating high-quality compost. The entire process typically takes 2-6 months, depending on conditions and management techniques.

Aeration and Turning Techniques

Proper aeration is essential for efficient composting. It provides oxygen to aerobic microbes and helps regulate temperature and moisture levels.

Turning the compost pile is a common aeration method. Use a pitchfork or compost aerator to mix materials every 1-2 weeks. This redistributes moisture and introduces fresh oxygen.

For passive aeration, insert perforated pipes into the pile or build it on a base of coarse materials. These techniques allow air to circulate without manual turning.

Larger operations may use forced aeration systems with blowers to maintain optimal oxygen levels throughout the pile.

Monitoring Temperature and Humidity

Temperature and humidity are key indicators of compost health. Use a compost thermometer to track internal temperatures regularly.

Ideal temperatures range from 130-150°F (54-66°C) during the thermophilic phase. If temperatures exceed 160°F (71°C), turn the pile to cool it down.

Maintain moisture levels at 40-60%. The compost should feel like a wrung-out sponge. If too dry, add water; if too wet, incorporate dry materials or turn more frequently.

Monitor humidity by squeezing a handful of compost. It should form a ball without dripping water. Adjust moisture levels as needed to keep the decomposition process active.

Vermicomposting: Using Worms to Enhance Compost

Vermicomposting harnesses the power of worms to transform organic waste into nutrient-rich compost. This method produces high-quality worm castings that serve as an excellent soil amendment for gardens and plants.

Setting Up a Worm Bin

To start vermicomposting, choose a suitable container with proper ventilation and drainage. A plastic bin with small holes works well. Add bedding material like shredded newspaper or cardboard, moistened to the consistency of a wrung-out sponge.

Introduce red wiggler worms (Eisenia fetida) to the bin. These worms thrive in composting environments. Add a small amount of food waste, burying it in the bedding to prevent odors and pests.

Maintain a balanced diet for the worms by providing a mix of nitrogen-rich materials (fruit and vegetable scraps) and carbon-rich materials (paper, dry leaves). Avoid meat, dairy, and oily foods.

Caring for Your Worms

Monitor moisture levels in the bin, keeping it damp but not waterlogged. Add dry bedding if too wet, or mist with water if too dry. Ensure proper air circulation to prevent anaerobic conditions.

Feed the worms regularly, but avoid overfeeding. Add new food only when the previous batch is mostly consumed. Chop food scraps into small pieces to speed up decomposition.

Harvest worm castings every 3-6 months. Separate worms from the finished compost by moving them to one side of the bin with fresh bedding and food. The worms will migrate, leaving behind nutrient-rich castings.

Use the harvested vermicompost as a soil amendment or organic fertilizer. It’s rich in beneficial microorganisms and provides essential nutrients for plant growth.

Using Your Compost Effectively

Proper application of mature compost can significantly enhance soil quality and plant growth. Knowing when compost is ready and how to incorporate it into your garden are key skills for successful composting in Ontario.

Maturity and Harvesting Compost

Rich compost is dark brown, crumbly, and smells earthy. It should no longer resemble the original materials. To test maturity, place a handful in a sealed plastic bag for 24 hours. If it smells sour or rotten when opened, it needs more time to decompose.

Harvest compost from the bottom of the bin where it’s most decomposed. Sift through a 1/2-inch screen to remove any large pieces. These can be returned to the active compost pile.

Store mature compost in a dry, covered area until ready for use. Good quality compost can be kept for several months without losing its beneficial properties.

Applying Compost in Your Garden

Use compost as a soil amendment by mixing it into garden beds before planting. Apply a 2-3 inch layer and work it into the top 6-8 inches of soil. For established plants, spread a 1/2 inch layer around the base, avoiding direct contact with stems.

When planting, add a handful of compost to each hole. This provides nutrients directly to plant roots. For container gardening, mix 1 part compost with 3 parts potting soil.

Make compost tea by steeping compost in water for 24-48 hours. Strain and use this nutrient-rich liquid to water plants or as a foliar spray. This provides a quick boost of nutrients and beneficial microorganisms.

Troubleshooting Common Composting Issues

Composting in Ontario can face some common challenges. Addressing these issues promptly helps maintain a healthy, productive compost pile.

Dealing with Pests and Odors

Pests and odors often indicate an imbalance in the compost pile. To deter flies, cover food scraps with a layer of brown materials or soil. Use a mesh screen to contain the pile and keep flying pests out.

For ant problems, the compost may be too dry. Add water and turn the pile to distribute moisture evenly. Foul odors typically stem from excess moisture or lack of oxygen. Mix in dry, carbon-rich materials like shredded newspaper or dry leaves to absorb moisture.

Turn the pile regularly to improve aeration and reduce anaerobic conditions. Avoid adding meat, dairy, or oily foods, which can attract pests and cause unpleasant smells.

Compost Too Wet or Dry

Proper moisture balance is crucial for effective composting. A too-wet pile becomes slimy and smelly. Add dry brown materials like leaves, straw, or shredded paper to absorb excess moisture. Ensure proper drainage and consider covering the pile during heavy rains.

If the compost is too dry, decomposition slows down. Add water gradually, mixing thoroughly. Aim for a consistency like a wrung-out sponge. Moisten dry materials before adding them to the pile.

Turn the compost regularly to distribute moisture evenly. In Ontario’s climate, monitor moisture levels closely, especially during hot summers and cold winters.
