Question: Composting 101: What Is Compost?

Answer:

Make a habit of adding compost to the soil each planting season because it is rich in nutrients, and it promotes soil microbes that aid plant growth. In a nutshell, compost is decomposed organic matter. Composting is a natural process of recycling organic material such as leaves and vegetable scraps into a rich soil amendment that gardeners fondly nickname Black Gold.

The Many Benefits of Compost
Compost energizes the soil food web, which is made up of microscopic bacteria and fungi, along with earthworms, crickets, and many other life forms. Many fungi form symbiotic, or mutually rewarding, partnerships with plant roots, making it possible for vegetables to feed themselves more efficiently. Research shows that compost enhances the ability of tomatoes and other vegetables to stand up to common diseases and may improve their flavor and nutrition, too. Compost also helps the soil retain moisture. Through composting you enhance your garden’s ability to grow healthy plants while reducing your volume of trash.

Where to Get Compost
You can buy bagged compost, but the best source is homemade. Like homemade soup, compost is different every time depending on what materials go into it, and there is generally no single perfect list of ingredients to make a good product. Typical ingredients include fruit and vegetable trimmings from your kitchen, old plants from your vegetable garden, and leaves and grass clippings from your yard. See How to Make a Compost Pile for more about making your own compost and see all the other articles in our compost section for expanded information.

Most gardeners who actively compost still need to buy compost from time to time, either in bulk or in bags. See Smart Compost Shopping for tips on buying commercially-produced compost for your garden.

What Is the Difference Between Compost and Fertilizer?
The simplest way to distinguish between compost and fertilizer is to remember this: Compost feeds the soil and fertilizer feeds the plants.

Fertilizer adds to the soil’s nutrient supply, but instead of feeding the soil food web, the ingredients in fertilizers are intended to meet the needs of fast-growing plants. While recommended amounts of compost can be quite general, fertilizer application rates are based on the needs of plants. Either organic or conventional fertilizers work well for vegetables, but organic fertilizers have been shown to be friendlier to the soil food web. Chemical fertilizer can also feed composting, but continual use may throw soil chemistry out of balance and discourage microbes. See fertilizer to explore your fertilizer options.
