Agricultural Liming Materials Test

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.
