When you think of dirt, you probably just think of that dark brown or black material that can be found in your garden or on a jobsite, right? It’s true that what you’re thinking of is actually dirt, but did you know that not all dirt is the same? There are different types of dirt that are best for different applications. Before you submit your next dirt order, learn about the different types of dirt below to ensure you're choosing the right product for your project.

Fill Dirt
Fill dirt is often the least expensive type of dirt. This material is used precisely to fill in a hole in the ground or to purposefully change the grade or elevation of a property. This product is usually taken from locations where the soil is being removed, such as at construction sites. In addition to dirt, most fill dirt may also contain rocks and sand.

In some cases, fill dirt is mixed with sand to make it lighter and provide better drainage. It is most commonly used on construction sites, but it can also be used for highway maintenance. Fill dirt can also be used for landscaping projects that require elevation changes, such as the addition of a swimming pool or waterfall.  

Topsoil
Topsoil refers to the top layer of soil, usually about the first 2-8 inches. This product is rich in organic material, including a high amount of decomposing plant and animal material as well as a high amount of nutrients. Topsoil is usually black in color and is typically recommended as an addition to home gardens, flower beds and lawns.

Black Dirt
Black dirt is not the same as topsoil, even though it may look the same. Black dirt typically contains iron and other chemicals, which is what gives it that dark brown or black hue. This material is commonly used in landscaping, gardens and lawns as well as for filling in low areas or creating walkways.

Although most types of dirt may look the same, they’re not always interchangeable. Before you order dirt for your next project, let one of Ozinga’s materials specialists help ensure you’re choosing the right product.
