Agricultural Liming Materials

Our liming material testing services are temporarily down. We expect to resume testing in August. If possible we recommend waiting to submit samples until then. Please call 612-625-3101 with any questions.


Notice for Quicklime Samples: 1-6-17

For quicklime samples, please include an MSDS and check the appropriate box on our submission form. This makes our technicans aware of any additional safety hazards and may also improve the accuracy of your results. Also make sure to comply with any necessary requirements for the shipment of these samples.

Our Liming Materials Analysis form is available for download and printing: Microsoft Office document icon liming_materials_17-18.doc

This test is 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 (ALM) to determine the Effective Neutralizing Power (ENP). These analyses are

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