Basics of Composting

Composting is a natural process that transforms organic waste into nutrient-rich soil. It plays a crucial role in reducing landfill waste and enhancing soil health for gardening and agriculture.

Understanding Compost

Compost is created by breaking down organic materials like food scraps, yard waste, and paper products. The process requires a balance of “green” nitrogen-rich materials and “brown” carbon-rich materials. Green materials include fruit and vegetable scraps, coffee grounds, and grass clippings. Brown materials consist of dry leaves, sawdust, and shredded paper.

Proper moisture and aeration are essential for effective composting. The pile should be damp but not soggy, similar to a wrung-out sponge. Regular turning or mixing helps introduce oxygen, speeding up decomposition.

Microorganisms like bacteria and fungi break down the organic matter. This decomposition generates heat, which is a sign of active composting.

Benefits of Composting

Composting offers numerous advantages for gardeners and the environment. It improves soil structure, enhancing water retention and reducing erosion. The nutrient-rich compost acts as a natural fertilizer, promoting plant growth and health.

Using compost reduces the need for chemical fertilizers, which can harm beneficial soil organisms and pollute waterways. It also helps suppress plant diseases and pests, leading to healthier gardens.

Composting diverts organic waste from landfills, where it would otherwise produce methane, a potent greenhouse gas. This diversion helps conserve landfill space and reduces transportation costs associated with waste disposal.

Composting and Climate Change

Composting plays a significant role in mitigating climate change. By diverting organic waste from landfills, it reduces methane emissions, which are 25 times more potent than carbon dioxide in trapping heat.

The process of composting sequesters carbon in the soil, helping to offset greenhouse gas emissions. When applied to gardens and farms, compost improves soil health, increasing its capacity to store carbon.

Compost use in agriculture can reduce the need for synthetic fertilizers, whose production is energy-intensive and contributes to greenhouse gas emissions. It also enhances soil’s water-holding capacity, reducing irrigation needs and conserving water resources.

Setting Up a Compost System

Establishing an effective compost system in Aurora, CO requires careful planning and consideration of key factors. The right setup will ensure efficient decomposition and produce high-quality compost for your garden.

Choosing the Right Compost Bin

Selecting an appropriate compost bin is crucial for successful composting in Aurora’s climate. Wire mesh bins allow good airflow but may dry out quickly in hot weather. Enclosed plastic bins retain moisture and heat, ideal for colder months.

For year-round composting, a three-bin system offers versatility. It allows for different stages of decomposition and easy turning of materials. Place the bins in a convenient location with some sun exposure, preferably near your garden.

Commercial bins are available, or you can build your own using wood pallets or cinder blocks. Ensure the bin size matches your household’s organic waste output – typically 3x3x3 feet is sufficient for most homes.

Balancing Browns and Greens

Proper ratios of carbon-rich “browns” and nitrogen-rich “greens” are essential for effective composting.

Browns (2-3 parts):
• Dry leaves
• Straw
• Shredded paper
• Wood chips

Greens (1 part):
• Grass clippings
• Fruit and vegetable scraps
• Coffee grounds
• Fresh plant trimmings

Layer materials, starting with browns at the bottom for good drainage. Aim for smaller pieces (1-2 inches) to speed up decomposition. Avoid meat, dairy, and oily foods to prevent odors and pests.

Optimizing Moisture and Aeration

Maintaining proper moisture and oxygen levels is critical for microbial activity in your compost. The pile should feel like a wrung-out sponge – moist but not soggy. In Aurora’s dry climate, you may need to water the pile occasionally.

To test moisture: Squeeze a handful of compost. If water drips out, it’s too wet. If it crumbles, it’s too dry.

Ensure adequate aeration by turning the pile every 1-2 weeks. Use a pitchfork or compost aerator tool to mix materials thoroughly. This introduces oxygen, speeds up decomposition, and prevents anaerobic conditions that cause odors.

In winter, insulate the bin with straw or leaves to maintain heat. During hot summers, monitor moisture levels closely and add water as needed to keep the composting process active.

Composting Practices for Aurora’s Climate

Aurora’s unique climate requires specific composting strategies to maintain an active decomposition process throughout the year. Adapting techniques for cold winters and consistent year-round maintenance are key to successful composting in this Colorado city.

Preparing for Cold Winters

In Aurora, winters can be harsh, necessitating extra care for compost piles. Insulate the pile with straw or leaves to retain heat. Use a larger bin, at least 3 feet wide and tall, to generate more internal warmth. Add high-nitrogen materials like coffee grounds or fresh grass clippings to boost microbial activity.

Consider using a compost tumbler, which allows for easy turning even in freezing temperatures. Place the compost bin in a sunny spot to maximize heat absorption. Chop materials into smaller pieces to speed up decomposition in colder months.

Maintaining the Compost Pile Year-Round

Consistent maintenance is crucial for year-round composting in Aurora. Monitor moisture levels, keeping the pile as damp as a wrung-out sponge. In dry periods, add water; in wet seasons, cover the pile to prevent waterlogging.

Turn the compost regularly, about once a week in summer and every 2-3 weeks in winter. Balance green and brown materials to maintain a carbon-to-nitrogen ratio of 30:1. Add layers of soil or finished compost to introduce beneficial microorganisms.

During hot summers, place the bin in partial shade to prevent excessive drying. In spring and fall, take advantage of abundant yard waste to boost your compost volume.

Types of Compostable Materials

Composting involves a variety of organic materials that break down over time. The key to successful composting lies in understanding which materials are suitable and how to balance them effectively.

Distinguishing Biodegradable and Non-Biodegradable

Biodegradable materials are essential for composting. These include fruit and vegetable scraps, eggshells, coffee grounds, and tea bags. Paper products like newspaper and cardboard are also biodegradable.

Non-biodegradable items such as plastics, metals, and glass should never be added to compost. These materials do not break down and can contaminate the final product.

Some biodegradable materials to avoid in compost include meat, dairy, and oily foods. These can attract pests and create unpleasant odors.

Handling Kitchen Scraps and Yard Waste

Kitchen scraps are rich in nitrogen and provide “green” materials for compost. These include fruit and vegetable peels, coffee grounds, and eggshells. It’s important to chop larger pieces to speed up decomposition.

Yard waste contributes “brown” materials, high in carbon. Examples include:

• Dry leaves
• Small twigs
• Grass clippings
• Straw or hay

Balancing green and brown materials is crucial. A general rule is to use three parts brown to one part green materials.

Identifying High-Nutrient Waste

Certain compostable materials are particularly rich in nutrients. These help create a more valuable end product for garden use.

High-nutrient compostables include:

• Coffee grounds (nitrogen)
• Banana peels (potassium)
• Eggshells (calcium)
• Grass clippings (nitrogen)
• Seaweed (trace minerals)

Using a variety of these materials ensures a well-balanced compost. It’s important to mix them thoroughly and monitor moisture levels for optimal decomposition.
