Understanding Composting Basics

Composting transforms organic waste into nutrient-rich soil amendment. This natural process reduces landfill waste while creating a valuable resource for gardens and plants.

What Is Composting?

Composting is the controlled decomposition of organic materials. It breaks down food scraps, yard waste, and other biodegradable items into a dark, crumbly substance called compost. Microorganisms play a crucial role in this process, feeding on the organic matter and converting it into a stable, soil-like product.

The composting process requires four key elements: organic matter, moisture, oxygen, and bacteria. When these components are balanced, they create an ideal environment for decomposition. Compost can be made in backyard bins, tumblers, or even indoor worm composting systems.

Benefits of Composting

Composting offers numerous environmental and personal benefits. It diverts organic waste from landfills, reducing methane emissions and conserving landfill space. This practice helps close the nutrient loop, returning valuable resources to the soil.

Compost improves soil structure, water retention, and nutrient content. It promotes healthy plant growth and reduces the need for chemical fertilizers. Gardeners and farmers use compost to enhance crop yields and soil quality.

Additionally, composting at home can save money on garbage disposal fees and store-bought fertilizers. It’s an educational tool for children, teaching them about natural cycles and environmental responsibility.

Composting Principles: Browns and Greens

Successful composting relies on balancing “brown” and “green” materials. Browns are carbon-rich materials like:

• Dry leaves
• Straw
• Shredded paper
• Wood chips

Greens are nitrogen-rich materials such as:

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

A general rule is to use about 3 parts browns to 1 part greens by volume. This ratio provides the right balance of carbon and nitrogen for optimal microbial activity. Proper layering of these materials ensures good air circulation and speeds up the decomposition process.

Moisture is also crucial. The compost pile should be as damp as a wrung-out sponge. Too much water can lead to anaerobic conditions and unpleasant odors, while too little slows down the process.

How to Start Composting in Gresham, OR

Starting composting in Gresham is straightforward and beneficial for the environment. Residents can choose between home composting or using community options. The process involves selecting a suitable bin, finding the right location, and understanding what materials to compost.

Choosing a Compost Bin

Gresham residents have several compost bin options. For home composting, enclosed bins or tumblers work well to control odors and pests. Open bins are suitable for yard debris. The city offers a free community compost cart for food scraps.

For those with limited space, countertop bins are ideal for collecting kitchen scraps. Larger households may prefer a three-bin system, allowing for different stages of decomposition.

When selecting a bin, consider:

• Size of your yard
• Volume of compostable materials
• Ease of use
• Local climate

Placement and Setup

Proper placement of your compost bin is crucial for efficient decomposition. Choose a level, well-drained area with partial shade. This helps maintain moisture without overheating the compost.

For home composting:

1. Clear the ground and place the bin directly on soil.
2. Ensure easy access for adding materials and turning the compost.
3. Keep the bin at least 2 feet away from structures to prevent pest issues.

The community compost cart is located at 138 NE 3rd St. Residents must register to receive the access code and usage instructions.

What to Compost

Successful composting requires a balance of “browns” and “greens.” Browns are carbon-rich materials, while greens provide nitrogen.

Browns include:

• Dry leaves
• Shredded paper
• Wood chips

Greens include:

• Fruit and vegetable scraps
• Coffee grounds
• Grass clippings

Avoid composting meat, dairy, or oily foods to prevent odors and pests. Gresham’s community compost cart accepts food scraps, which helps reduce waste and benefit the environment.

Mix materials in roughly equal parts. Keep the compost moist but not soggy. Turn the pile regularly to aerate and speed up decomposition.

Maintaining Your Compost Pile

Proper maintenance is crucial for a successful composting process in Gresham, OR. Regular attention to key factors ensures efficient decomposition and high-quality compost production.

Balancing Greens and Browns

A well-balanced compost pile requires a mix of nitrogen-rich “green” materials and carbon-rich “brown” materials. Greens include fresh grass clippings, food scraps, and coffee grounds. Browns consist of dry leaves, straw, and shredded paper.

Aim for a ratio of roughly 3 parts browns to 1 part greens by volume. This balance provides optimal conditions for decomposition. If the pile smells unpleasant, add more browns. If it’s not breaking down quickly enough, incorporate more greens.

Layering these materials helps maintain the balance. Start with a layer of browns, followed by greens, and repeat. This structure promotes air circulation and proper decomposition.

Managing Moisture and Aeration

Proper moisture levels and aeration are essential for compost microorganisms to thrive. The pile should feel like a wrung-out sponge – moist but not soggy.

If the pile is too dry, add water or green materials. If it’s too wet, mix in dry browns or leave the pile uncovered during dry weather. Excess moisture can lead to anaerobic conditions and unpleasant odors.

Aeration introduces oxygen, vital for aerobic decomposition. Create air pockets by inserting stakes or pipes into the pile. This process helps bacteria and fungi break down organic matter efficiently.

Gresham’s climate may require adjustments to maintain ideal moisture levels. During rainy periods, cover the pile to prevent waterlogging. In dry spells, monitor and add water as needed.

Turning and Temperature Monitoring

Regular turning accelerates decomposition by redistributing materials and introducing fresh oxygen. Turn the pile every 1-2 weeks using a pitchfork or compost aerator tool.

Monitor the pile’s temperature with a compost thermometer. A well-functioning pile should reach 130-150°F (54-66°C) in its core. This heat kills weed seeds and pathogens.

If the temperature drops, turn the pile to reintroduce oxygen. Add water if it’s too dry, or nitrogen-rich materials if it lacks “fuel” for microorganisms. In colder months, insulate the pile with straw or leaves to maintain heat.

Consistent turning and temperature management ensure that all parts of the pile decompose evenly, resulting in uniform, high-quality compost for Gresham gardens.

Troubleshooting Common Composting Problems

Composting in Gresham, OR can face several challenges. Identifying and addressing these issues promptly ensures a healthy, productive compost pile.

Odors and Pests

Unpleasant odors often indicate imbalances in the compost. A rotten egg smell suggests anaerobic conditions due to compaction or excess moisture. To fix this, turn the pile regularly to improve aeration.

An ammonia smell points to too much nitrogen-rich material. Add more carbon-rich materials like dry leaves or shredded paper to restore balance. This adjustment helps reduce methane emissions and promotes proper decomposition.

Pests can be deterred by proper management. Cover food scraps with a layer of carbon materials or soil. For fly problems, use a mesh screen to contain the pile. Ants typically indicate a dry pile – add water to discourage them.

Slow Decomposition

Slow decomposition often results from an imbalance of carbon and nitrogen or insufficient moisture. Ensure a proper mix of “green” (nitrogen-rich) and “brown” (carbon-rich) materials.

Aim for a ratio of about 3 parts carbon to 1 part nitrogen. This balance provides energy for microorganisms and supports efficient breakdown of organic matter.

Chop materials into smaller pieces to increase surface area for microorganisms to work on. Turn the pile regularly to distribute moisture and oxygen, speeding up the process.

Moisture Imbalance

Proper moisture is crucial for composting. A pile that’s too wet becomes anaerobic, slowing decomposition and creating odors. If your compost is soggy, add dry, carbon-rich materials and turn the pile to improve aeration.

A dry pile slows microbial activity. The compost should feel like a wrung-out sponge. If it’s too dry, add water while turning the pile. In Gresham’s climate, you may need to water during dry summer months.

Cover your pile to control moisture. This helps retain warmth and protects from excess rain, maintaining ideal conditions for microorganisms and mineral release.

Special Types of Composting Methods

Gresham residents can explore several effective composting techniques to suit their needs and space constraints. Each method offers unique benefits for transforming organic waste into nutrient-rich soil.

Vermicomposting

Vermicomposting utilizes special worms, typically red wigglers, to break down food scraps and create nutrient-dense compost. This indoor method is ideal for apartments or homes with limited outdoor space.

To start vermicomposting, acquire a bin with air holes and bedding material like shredded newspaper. Add red wigglers and feed them fruit and vegetable scraps, coffee grounds, and tea bags.

The worms consume the organic matter and produce castings rich in beneficial microorganisms. Harvest the compost every few months by moving the contents to one side and adding fresh bedding to the other. The worms will migrate, leaving behind finished compost.

Hot Composting

Hot composting is a fast, efficient method for processing large amounts of organic material. It requires careful management of carbon-to-nitrogen ratios, moisture, and aeration.

Build a pile at least 3 feet cubed, alternating layers of “green” nitrogen-rich materials (grass clippings, food scraps) with “brown” carbon-rich materials (dry leaves, straw). Keep the pile moist and turn it regularly to maintain oxygen levels.

The center of the pile will heat up to 130-150°F, killing weed seeds and pathogens. With proper maintenance, hot composting can produce finished compost in as little as 4-6 weeks.

Cold Composting

Cold composting is a low-maintenance approach suitable for Gresham gardeners with less time or physical ability. Simply pile yard waste and kitchen scraps in a designated area and let nature do the work.

Add both green and brown materials as they become available. While slower than hot composting, this method requires minimal effort and still produces quality compost.

To speed up decomposition, chop materials into smaller pieces before adding them to the pile. Avoid meat, dairy, and oily foods to prevent odors and pests.

Expect finished compost in 6-12 months, depending on climate and materials used. Cold composting works well for processing garden waste and enriching soil over time.

Using Composted Material

Composted material offers numerous benefits for gardens and landscaping. It enhances soil health, improves plant growth, and promotes sustainability in Gresham, OR.

Applying Compost to the Garden

Nutrient-rich compost acts as a natural fertilizer for plants. Spread a 1-2 inch layer of compost over garden beds before planting. Work it into the top 6-8 inches of soil using a garden fork or tiller.

For established plants, apply compost as a top dressing around the base, avoiding direct contact with stems. Use 1/4 to 1/2 inch of compost for perennials and 1-2 inches for trees and shrubs.

Vegetable gardens benefit from compost applications in spring and fall. Mix compost into planting holes for new plants to give them a strong start.

Composting as Mulch

Compost serves as an effective organic mulch. Apply a 2-3 inch layer around plants, leaving space near stems and trunks to prevent rot.

This mulch layer retains soil moisture, suppresses weeds, and regulates soil temperature. As it breaks down, it adds organic matter to the soil, improving its structure and fertility.

Compost mulch is particularly beneficial for acid-loving plants like rhododendrons and blueberries. It helps maintain soil pH and provides a steady supply of nutrients.

Compost Teas and Extracts

Compost teas offer a liquid form of compost benefits. To make compost tea, steep finished compost in water for 24-48 hours. Use a ratio of 1 part compost to 5-10 parts water.

Strain the mixture and apply it as a foliar spray or soil drench. This nutrient-rich liquid boosts plant growth and helps fight off diseases.

For a quicker option, make compost extract by mixing compost with water and using it immediately. This method provides similar benefits to compost tea but requires less preparation time.
