Frequently Asked Questions

What is top soil?

There are many names for what is known as topsoil and it can be confusing. Some customers will ask for dirt and some will ask for topsoil when they mean potting soil. So what is top soil? Topsoil refers to native soil which is usually composed of sand, silt and clay.  In certain areas on the island of Hawai’i, a unique combination of volcanic ash deposits, lush vegetation, humidity and time have conspired to create a deep layer of topsoil rich in organic matter. At Soil Plus, our top soil is worth its weight in gold. This nutrient-rich topsoil is an ideal base to add compost and cinder, creating the perfect growing medium for plants, grass, crops and trees. Our 1/3rd Mix, CTH and Cinderless Blend are soil blends that contain top soil. If you’re looking for plain topsoil with nothing added to it, we do have this available as well. Be sure to ask for plain topsoil (also known as Cinderless without Compost) at our sales office.

How much is a yard of topsoil?

A cubic yard of topsoil covers approximately 10 ft x 10 ft at 3 inches deep and weighs about 1500 lbs. Most pickup trucks can hold about a cubic yard of soil, but be sure to check the specs on your specific truck. Prices for our soil blends and plain topsoil range from $46 to $80. Please call our sales office for help determining which type of soil is best for your project.

How much does a yard of topsoil weigh?

A cubic yard of topsoil weighs about 1500 lbs, or ¾ ton. Consult your vehicle's owner's manual to confirm how much your truck or trailer can hold.

Where to buy topsoil in bulk?

If you’re wondering where to buy top soil in bulk, look no further! We sell topsoil by the cubic yard and can sell as little as half a cubic yard. Come with your pickup truck or schedule a delivery today!

What is topsoil used for?

Plain topsoil (without anything added to it) is ideal for imu pits. It can also be used as a base for creating your own garden or potting soil blend. Our soil blends include topsoil. The 1/3rd Mix contains black cinder, topsoil and macadamia nut husk compost. The CTH blend contains red cinder, topsoil and mac nut husk compost. Both blends have been amended to ensure neutral Ph and all the necessary nutrients required for healthy plants. The Big Island Dirt Blend contains topsoil and compost with no amendments added. This blend would be the closest we have to organic.

How much topsoil do I need?

To determine how much topsoil (or other material) is needed for your project, measure the width, length and depth of the area needing the soil. Once you have those numbers, visit our Volume Calculator to determine how many cubic yards you will need. How much topsoil do I need to grow grass? A Google search will produce answers between 2 inches to 8 inches. While 6 inches will give you great results, at least 4 inches is ideal. However, be sure to order 20% more than you need to account for compaction.
