The cost of a ton of lime delivered is never a fixed number, as the final price is a dynamic calculation based on the material, the distance it travels, and the volume purchased. Most inquiries refer to agricultural limestone, a soil amendment used to raise soil pH and improve nutrient availability for plant growth. Determining the true financial outlay requires separating the cost of the raw material from the expenses associated with moving and applying this dense, heavy product. The price you ultimately pay reflects local geology and the logistics required to get the material onto your property.
Understanding the Base Price of Lime
The initial cost of the lime product, known as the Free On Board (FOB) price at the quarry or supplier, depends primarily on its form and quality. Bulk agricultural lime, a finely pulverized powder, is the most common and least expensive form per ton, often priced between $5 and $20 at the source. This lower cost is due to minimal processing beyond crushing the raw limestone rock.
The value of the material is determined by its purity, measured by the Calcium Carbonate Equivalent (CCE) or Effective Neutralizing Power (ENP). A higher CCE percentage indicates a greater capacity to neutralize soil acidity, meaning less material is needed to achieve the same result. Cheaper sources may have a lower CCE, requiring higher application rates that negate initial price savings when factoring in total tons needed.
More processed forms of lime carry a substantially higher per-ton cost. Pelletized lime, where fine powder is pressed into granules for easier spreading, can cost between $160 and $280 per ton. The convenience and ease of application often make this a trade-off for smaller projects where bulk delivery is impractical. Hydrated lime is chemically reactive and provides a faster pH correction, but it is much more expensive and typically reserved for specialized applications.
Transportation Costs
Transportation is frequently the largest variable component when calculating the delivered price of bulk lime. Since lime is a high-volume, low-value commodity, the distance from the quarry to the application site heavily influences the final cost per ton. Hauling this dense material requires specialized dump trucks, which often incur fuel surcharges and hourly rates.
Trucking rates can be calculated as a flat fee per ton or a variable rate per mile. Bulk hauling charges often add $5 to $12 or more per ton to the base price, depending on the travel distance. Moving a 25-ton load even 50 miles one-way can quickly double the initial quarry price of the material.
Most suppliers enforce a minimum delivery requirement, typically needing a full truckload of 20 to 25 tons to make the trip financially viable. If a project requires less than this minimum, the buyer is often charged the full truckload cost or a premium to cover the empty capacity. Delivery logistics also vary; a simple dump-and-pile service is cheaper than delivery via a specialized spreader truck that applies the material directly. These factors mean that buyers in different regions can pay vastly different delivered prices for the exact same product.
Calculating the Total Project Expense
Moving beyond the delivered material cost, the total financial outlay for a liming project includes the expense of proper application. If a service is hired, spreading fees typically range from $5 to $20 per ton, depending on local labor rates and the complexity of the terrain. Alternatively, a do-it-yourself approach requires renting a heavy-duty spreader buggy, which can cost hundreds of dollars per day, plus the expense of a tractor capable of towing and loading the material.
Before any lime is purchased, an accurate soil test is required to determine the application rate and the total tonnage needed. Soil testing identifies the existing pH and the soil’s buffering capacity, providing a specific recommendation in pounds or tons per acre. Miscalculating this requirement can lead to overspending or under-applying, which fails to correct the soil problem.
When consolidating all these expenses—the base material cost, transportation fee, and application expense—the final price of lime applied commonly falls into a broad range. Depending on the distance from the quarry and the quality of the material, a realistic total cost can range from $30 to $85 per ton applied. Hidden costs, such as the initial soil testing fee or the labor required for delivery and spreading, should be incorporated into the final project budget.
