The Role of Composting in Edible Landscapes

As stewards of the environment, there is no better time than now to consider the impact of our daily decisions on the world around us.

An edible landscape is one way to promote sustainability in agriculture while creating a beautiful, functional space in your home.

In this blog post, I will discuss the role of composting in creating edible landscapes and how it can contribute to an overall healthier planet.

By the end of this article, you will understand the benefits of composting, different composting methods, and how to use compost to transform your garden.

Let’s dive right in.

What is composting?

Composting is the process of breaking down organic material (such as food waste, grass clippings, leaves, and paper) into a nutrient-rich soil amendment. Rather than sending these materials to landfills where they would release methane, a greenhouse gas that contributes to global warming, composting recycles them by turning them into a useful product.

The basic principles of composting include combining the right mix of carbon-rich (brown) materials, such as leaves, hay, or sawdust, with nitrogen-rich (green) materials like food scraps or grass clippings. You should also maintain a proper moisture level and ensure that the compost pile has enough oxygen to support the microbes that break down the organic matter.

There are several types of composting methods that you can choose from, including hot composting, cold composting, and vermicomposting. Hot composting produces compost more quickly but requires more upkeep, while cold composting is a more hands-off technique that can take up to a year to produce finished compost. Vermicomposting, or composting with worms, can be done indoors or outdoors and is a great option for people who live in apartments or who don’t have access to outdoor space.

Composting can seem daunting at first, but it’s actually a simple and straightforward process. Anyone can do it with a little bit of knowledge and effort. Plus, the benefits of composting far outweigh the initial investment of time and energy required to get started.

Benefits of Composting

Composting not only helps to keep waste out of landfills, but also provides benefits to your garden and the environment. By composting, you can improve the quality of your soil, increase biodiversity and help preserve water resources.

Improved Soil Quality: Composting helps create healthy soil by adding organic matter that improves the soil structure, helps with nutrient retention and aeration. The organic matter also helps retain moisture and can help prevent soil erosion.

Increased Biodiversity: Composting encourages the growth of beneficial microbes and fungi in the soil, which can help create a thriving ecosystem in your garden. Having a diverse range of organisms in your soil can help suppress diseases and pests.

Reducing Methane Emissions: When organic matter is disposed of in landfills, it can produce methane, a greenhouse gas. Composting helps to prevent the production of this potent greenhouse gas.

Reducing Waste in Landfills: The average U.S. household generates over 1,000 pounds of organic waste each year, which goes to the landfill. Composting helps divert organic matter from landfills, decreasing the amount of waste that is sent to the landfill.

Conserving Water: Adding compost to soil can help it retain water and reduce runoff, which can help save water and prevent soil erosion.

Incorporating composting into your gardening routine provides a simple way to reduce your environmental impact and promote a healthy ecosystem in your backyard.

Composting is an essential practice for creating healthy soil for growing food, and edible landscapes are no exception. If you are planning an edible landscape, incorporating composting into your plans is a must.

By adding compost to your edible landscape, you are not only improving the soil quality, but you are also reducing waste in landfills. Healthy soil means healthier plants, which in turn means a better harvest.

One example of incorporating compost in edible landscapes is by topdressing your garden beds with compost. A layer of compost on top of the soil will introduce organic matter, nutrients and beneficial microorganisms to the soil, which will help your plants absorb nutrients.

Another example is using compost to create a mulch layer around your plants. The layer of mulch helps retain moisture, suppress weeds, and soil temperature moderation.

Lastly, the connection between composting, sustainability and local food movement is very close. Incorporating practices such as composting in your edible landscapes, helps your garden produce healthier, more nutrient-rich, and organic produce. The practice of growing your own food locally reduces the carbon footprint of the food in the supply chain, and subsequently helps grow the local economy.

By adding compost to your edible landscape garden, you are supporting regenerative agricultural practices, and contributing to a more sustainable food system.

Essential Elements of Composting

Composting requires a balanced combination of carbon-rich and nitrogen-rich materials. Too much carbon leads to slow decomposition, while too much nitrogen can lead to an unpleasant odor. Here are a few essential elements to keep in mind when composting:

1. Carbon-to-Nitrogen Ratio (C:N)

The balance between carbon and nitrogen is referred to as the C:N ratio. The ideal ratio is between 25:1 to 30:1, with carbon being the dominant element. Carbon-rich materials include brown leaves, straw, wood chips, and shredded paper. While nitrogen-rich materials include grass clippings, manure, and kitchen scraps.

2. Moisture Content

Moisture is essential for composting, but too much or too little can disrupt the process. Aim for a moisture level of 50 to 60 percent. To determine if your compost pile has enough moisture, grab a handful and squeeze it. It should feel like a damp sponge. If it’s too dry, add water, and if it’s too wet, add dry materials like leaves.

3. Oxygen Levels

Composting requires oxygen to facilitate the decomposition process. Lack of oxygen can lead to anaerobic conditions, which results in smelly, slimy, and inefficient composting. Turning the compost pile regularly, using a compost tumbler, or using aeration systems can help maintain oxygen levels and speed up the process.

4. Temperature

Composting generates heat, which is a sign that the decomposition process is working. The ideal temperature range for a compost pile is between 120 to 160°F (49 to 71°C), which is hot enough to kill pathogens and weed seeds. If the temperature is too low, the composting process will take longer, and if the temperature is too high, it may kill beneficial bacteria.

By maintaining the carbon-to-nitrogen ratio, moisture content, oxygen levels, and temperature, you can create high-quality compost. A well-maintained compost pile can produce nutrient-rich soil amendment that you can use in your edible landscapes.

DIY Composting Methods and Techniques

Composting is a great way to reduce waste, improve soil health, and create nutrient-rich organic matter for your garden. Fortunately, there are several easy and effective DIY composting methods that you can use at home.

Composting with Kitchen Scraps

One of the simplest ways to compost is by using kitchen scraps. Instead of throwing away food scraps, you can use them to create a compost pile. Collect vegetable and fruit scraps, eggshells, coffee grounds, and tea bags in a compost bin. Add dry leaves, grass clippings, or shredded newspaper to balance the carbon-to-nitrogen ratio. Stir the compost pile from time to time, and keep the moisture content consistent.

Tumbler Composting

Tumbler composting is an efficient composting method that allows you to make compost in a short time. A tumbler compost bin is a drum that you can rotate easily, providing aeration and mixing to the composting materials. This method is perfect for composting in small spaces and for those with limited time.

Vermicomposting (Composting with Worms)

Worms are great at breaking down organic matter into nutrient-rich compost. Vermicomposting is a simple and effective technique for composting that uses red worms or earthworms. Create a worm bin by using a container with air holes, bedding materials such as shredded newspaper, and food scraps. The worms will eat the food waste and turn it into vermicompost. Worm castings, or worm poop, are rich in nutrients and can be used as a fertilizer for plants.

Bokashi Composting

Bokashi composting is a Japanese fermentation technique that uses beneficial bacteria to break down organic matter. This method is efficient and can compost almost all types of food waste, including dairy and meat. A Bokashi bin is a container that has a tight-fitting lid and a drainage tap. Add kitchen scraps, sprinkle some Bokashi bran, which is a mixture of bran and microorganisms, cover the scraps with more bran, and repeat the layering. When the bin is full, let it ferment for 2-3 weeks. The food waste will turn into a dark, fermented material that can be added to your garden soil.

Composting not only reduces waste but also adds vital nutrients to the soil. By choosing one or more of these DIY composting methods, you can help create a healthier planet and a healthier you.

How to Use Compost

Using compost is a straightforward process that can help improve soil fertility and plant growth. Here are some ways you can use compost to benefit your edible landscape:

If you do not already have a garden bed, begin by preparing your soil through tilling and removing any weeds and rocks. Then layer on top a few inches of compost and mix it well into the soil for optimal distribution. By doing so, you will ensure your plants receive the necessary nutrients and minerals to grow healthy.

If you already have plants or vegetables already growing in your garden, topdressing with compost can help add necessary nutrients to the soil surface. All you have to do is cover the area around the base of the plant with an inch or two of compost.

Compost tea can offer an immediate boost of nutrition for your plants. To make it, soak compost in water for a few days and stir it occasionally. Strain out the water and use it as a liquid fertilizer for your plants. With compost tea, your plants will thrive from the bacteria and fungi contained within the concoction.

Using compost as a mulch surrounding your plants provides crucial benefits. It lowers soil erosion, retains moisture, and lessens surface temperatures while adding organic matter to the soil. Simply add about one to two inches of compost surrounding your plants for an even layer of mulch.

Remember, composting needs some patience and experimentation before determining what composting method works for you. By using compost in each of these ways, you will achieve a natural, healthy, and sustainable garden.

Common Challenges in Composting and how to overcome them

Composting is a great way to reduce waste, improve soil quality, and help the environment, but sometimes it can be challenging. Here are some common challenges and tips for overcoming them:

Odor control

One of the biggest complaints about composting is the smell. To reduce odors, try adding more “brown” materials, like dried leaves or straw, which help balance the “green” materials, like fruit and vegetable scraps. Also, make sure to mix your compost regularly, keep it moist but not too wet, and avoid adding meat or dairy products, which can produce unpleasant odors.

Pest management

Pests like fruit flies, ants, and rodents can be a problem in a compost pile. To prevent pests, avoid adding oils, dairy, and meat scraps, and make sure to bury food scraps under a layer of leaves, soil, or other materials. Keeping your compost moist but not too wet can also help prevent pests.

Troubleshooting common composting problems

If you’re having trouble with your compost pile, there are a few things to check. First, make sure your pile is getting enough oxygen. Turning it regularly can help with this. Second, check the temperature. A good compost pile should heat up in the middle and stay around 130-160 degrees Fahrenheit. Finally, make sure your pile has the correct carbon-to-nitrogen ratio - this can be fixed by adjusting the amount of dry browns and green wet materials that you add.

By following these tips, you can overcome common composting challenges and make the most of your compost pile. With a little patience and effort, you can turn food scraps and yard waste into nutrient-rich soil that will help your edible landscape thrive.

Final Thoughts

In conclusion, composting plays a critical role in developing sustainable agriculture practices and creating edible landscapes.

By properly composting organic waste, gardeners and homeowners can reap countless benefits, including healthy soil and a thriving local food movement.
