Ag Lime Cost Per Ton 2026

Buyers typically pay for agricultural lime by the ton, with price driven by material type, region, and distance to the field. The cost per ton and the total project price depend on lime purity, particle size, and application rates.

Assumptions: region, lime type (pure vs dolomitic), and application rate (tons per acre) affect costs.

Overview Of Costs

Typical cost ranges for agricultural lime reflect bulk material pricing and common application needs. Low-cost bulk lime generally ranges from $15 to $25 per ton, mid-range from $28 to $40 per ton, and high-quality or dolomitic lime can exceed $40 per ton. Labor for spreading and equipment use add to the project, often measured per acre.

Per-acre costs often combine material and application, commonly around $30-$120 per acre for lime alone, and roughly $60-$160 per acre when including spreading and equipment. Assumptions: field size, soil pH target, and local labor rates impact total.

Notes: Prices reflect U.S. bulk agricultural lime markets; bagged lime typically costs more per ton than bulk deliveries.

Cost Breakdown

Category	Low	Average	High	Notes
Materials	$15	$28	$40	Typically price per ton; purity matters
Labor	$8/acre	$18/acre	$25/acre	Spreading and soil contact time
Equipment	$5	$12	$20	Spreaders or loaders; often included in labor rate
Delivery/Disposal	$5	$10	$15	Transport distance influences cost
Contingency	$2	$6	$10	Weather delays or extra lime needed

What Drives Price

Material quality and regional transport are major cost drivers for ag lime. The contrast between calcitic and dolomitic grades affects price per ton, while the distance from quarry to field adds delivery charges. Other drivers include required application rate (tons per acre) and soil pH targets.

Quality indicators to watch: fineness (particle size), purity percentage, and whether the lime is pelletized or ground. Dolomitic lime may cost more but supplies magnesium alongside calcium. Local demand and seasonal stock can also shift pricing.

Ways To Save

Bundle purchases and optimize application timing to reduce per-ton and per-acre costs. Ordering in larger quantities lowers unit price, while coordinating with neighboring fields can cut delivery fees. Choosing the right lime type for soil tests avoids overpaying for unnecessary magnesium or purity.

Consider soil testing to determine exact lime needs and target pH. Using the minimum effective rate lowers overall expenditure, and timing lime application with off-peak periods may yield lower labor and equipment costs.

Regional Price Differences

Prices vary by region across the United States. In the Midwest, bulk lime tends to be around $22-$40/ton, with delivery adding $5-$15/ton depending on distance. The Southeast can see $18-$38/ton, while the Pacific Northwest may run higher due to transport and demand. Rural areas often incur higher delivery surcharges than urban or suburban regions.

Labor & Installation Time

Spreading costs depend on field size and method. For a typical one-acre field, spreading lime might require 0.5–2 hours of labor depending on equipment and terrain. A single-pass spreader can reduce time, while rough or hilly terrain may increase it. Labor hourly rates in the U.S. commonly range from $40 to $75 per hour.
