It’s the age old question of which type of soil is the right type of soil? Choosing between topsoil, fill dirt, and compost can be confusing. Compost isn’t even technically soil!
Sure, there are similarities, but what makes them different can literally be a matter of life and death for you plants. The following article explains the differences between topsoil vs. fill dirt vs. compost. Which one will work best for your project?
When choosing topsoil vs. fill dirt vs. compost…topsoil vs. fill dirt vs. compost, information about topsoil, fill dirt, compost it’s important to consider a few things. For example, are you planning to plant in the material? Do you need to recondition existing soil or topdress a lawn? Finally, are you going to use the material to fill in a hole or level terrain? Each of these projects requires a different type of material. It is essential that you know the difference before making a selection.
Topsoil
Topsoil comes from the top five or so inches of soil. It is the part of the soil that has the most organic material. Its organic material and structure make it an ideal growing environment. Some topsoil is manufactured. This topsoil is often a combination of compost and other materials (screened soil and sand) that help with drainage and root support. Still, regardless of whether or
not the topsoil is naturally sourced or manufactured, it is an ideal growing environment for a variety of plants.
Topsoil is a cornerstone in landscaping and gardening projects. It’s used to create fertile beds for planting flowers, shrubs, trees, and grass. Gardeners and landscapers rely on topsoil to improve soil quality, enhance drainage, and promote robust plant growth. Topsoil is also vital for establishing lawns and creating garden beds.
Fill Dirt
Fill dirt is the term used to describe soil that’s excavated from one area and used to fill in another. It’s generally sourced from construction sites, grading projects, or excavations. Fill dirt is not enriched with organic matter and is often composed of subsoil or clay, making it dense and less fertile. As its name suggests, fill dirt is often used to fill holes, level terrain, and more. It is not
considered a growing medium because it lacks the organic material and structure that plants need to grow strong and healthy. Most fill dirt has a high amount of clay and sand, which is what makes it ideal for certain projects.
Compost
Compost is not soil. In fact, it lacks the structure needed for plants to build a strong root system. Instead, compost is considered a soil amendment. It is decomposed organic matter that is rich in microorganisms and nutrients. When added to soil, it improves drainage and increases the likelihood that plants will grow a strong root system. Compost also helps plants naturally resist
disease and pests.
