When planning large-scale landscaping or construction projects, understanding the cost of soil is a primary concern. Purchasing soil in bulk is the most economical choice for extensive work, compared to buying individual bags. The price depends on several variables, including the type of soil, where you live, and how much you order. Calculating the total expense requires considering the logistics and quality of the material beyond a simple per-unit cost.
Defining a Cubic Yard of Dirt
Bulk soil is sold by the cubic yard, the standard unit of measurement in the industry. A cubic yard represents a volume of three feet wide by three feet long by three feet high, totaling 27 cubic feet. This volume is necessary for accurately estimating material needs for a project, such as leveling a yard or building a garden bed.
One cubic yard of soil covers approximately 100 square feet to a depth of three inches. The weight fluctuates significantly based on the material’s moisture content and composition. Dry soil typically weighs around 1,080 pounds, but wet soil can weigh up to 2,000 pounds (one ton). This variable weight is a factor in delivery costs, as trucks have weight limits.
Average Cost of Standard Soil
The baseline price for bulk soil is determined by two common types: clean fill dirt and standard screened topsoil. Clean fill dirt is subsoil without organic matter, suitable for leveling or filling large holes, and is the least expensive option. The raw material cost generally ranges from $5 to $25 per cubic yard before delivery fees are applied.
Standard screened topsoil is the upper layer of earth, filtered to remove large rocks and debris. It is priced higher due to this processing and its organic content, typically costing between $20 and $40 per cubic yard. This price represents the cost of the material when purchased in large volumes.
Key Factors Influencing Pricing
The final price per yard can vary substantially based on the soil’s quality, the quantity purchased, and the cost of transportation. Soil composition is the most significant factor, with specialized blends commanding a premium over basic fill dirt.
Specialty mixes, like garden mix, triple mix, or organic compost blends, are engineered for specific horticultural purposes and contain amendments like sand, compost, and manure. These nutrient-rich products often cost between $60 and $165 per cubic yard.
Delivery fees can drastically increase the total cost of an order. Suppliers calculate these fees based on factors such as the distance from the yard to the project site and the size of the truck required. Delivery charges often range from $15 to $60 for a typical load, but they can exceed $200 for long distances or remote locations. Many suppliers offer bulk discounts or free delivery for large orders, often 10 cubic yards or more, lowering the overall price per yard.
Where to Purchase Bulk Dirt
Purchasing bulk soil efficiently depends on the type of material and the volume required. Local landscape supply companies are the most common source for homeowners, as they offer a wide variety of screened topsoil, garden mixes, and decorative materials. These suppliers often have easy access for pickup or can arrange delivery with their own fleet of dump trucks.
For projects requiring large amounts of inexpensive fill dirt, local quarries or construction/excavation companies may be the best option. Construction sites often have excess dirt they are willing to part with for a nominal fee or even for free, though this material may be unscreened and contain debris.
Garden centers and nurseries sometimes sell bulk quantities of premium, specialized mixes, which are ideal for high-value garden beds.
