Agricultural Liming Materials

Analysis and Pricing

September 1, 2022 - New prices begin today!

These tests are offered to Ag Lime producers and others who want to evaluate the quality of liming materials. There are three analyses performed on agricultural liming materials to determine the Effective Neutralizing Power (ENP). They include:

  1. Purity or Total Neutralizing Power,
  2. Particle size, percent passing through 8, 20 and 60 mesh sieves, and
  3. Moisture content.

The Liming Materials Analysis Request Sheet (xlsx) contains all current prices. This document is also available as a pdf and a fillable pdf. When sending a sample, provide FIVE POUNDS of material and make sure the bag seals tightly (and will not open during shipping).

MDA Sampling Requirements

Please see the Minnesota Department of Agriculture's sampling requirements webpage. Information on the entire Ag Liming Materials program can be found here.

Note for Quicklime Samples

For quicklime samples, please include an Safety Data Sheet (SDS) and check the appropriate box on our submission form. This makes our technicians aware of any additional safety hazards and may also improve the accuracy of your results. Make sure to comply with any necessary requirements for shipping these samples.


Samples are kept for three months, then discarded.
