Liming Material

Liming material refers to any material for which the calcium and magnesium content is used to neutralize soil acidity. These materials include:

  • Limestone;
  • Hydrated lime;
  • Burnt lime;
  • Industrial by-product; and
  • Marl and shell.

A Lime License is required for anyone to manufacture, sell, or distribute liming material in Ohio. Licenses are required for each of the following:

  • Each location at which liming material is manufactured in Ohio;
  • Each location out of the state from which liming material is distributed or sold in Ohio to non-licensees.

Sellers and distributors are not required to be licensed if the manufacturer of the liming material to be distributed or sold is licensed (ORC 905.53).

New License Checklist

Licenses expire annually on December 31 and can be renewed for a $50 fee.

Label Information

If liming material is sold or distributed in packages, each container must be labeled with the following information:

  • Net weight of contents in pounds as determined by a sealed weighing device;
  • Product name and type of liming material, which includes the grade, for all except the oxide and hydrate forms;
  • Name and address of manufacturer, seller, or distributor as shown on the license; and
  • Guaranteed analysis in whole numbers which includes:
    • The minimum percentages of weight of elemental calcium and magnesium;
    • The total neutralizing power expressed as weight percent of calcium carbonate;
    • The minimum percentages of weight passing through numbers 8, 20, 60, 100 U.S. standard sieves;
    • The effective neutralizing power expressed on the basis of pounds per ton as a percentage of the fineness index, multiplied by the total neutralizing power and percentage of dry matter.

For nonpackaged (bulk) liming material, the purchaser must be supplied, upon delivery, with a shipping invoice/delivery ticket containing the following information:

  • The name and address of the purchaser;
  • The date of sale;
  • Net weight of contents in pounds as determined by a sealed weighing device;

Tonnage Reports and Inspection Fees

Annual tonnage reports are due for sales between the period of January 1 - December 31, to be filed before February 9. These reports should state the net tons of liming material sold or distributed to a non-licensee in this state, by county, by oxide and hydrate forms, and by grade. If more than 2,500 tons of agricultural liming material is sold or distributed in this state, an inspection fee will be applied. This fee is one-fourth of one cent ($0.0025) for each ton over 2,500 tons, up to a maximum fee of $300. There is a late fee of $10 or 10% of the amount due, whichever is greater. For tonnage reports found to be incorrect, a penalty of 10% of the amount due will be assessed.
