All agriculture liming materials distributed in this State shall use the following standard to determine the fineness of the liming material;
Multiply the percent of total material passing a number 4 sieve by .1 (one tenth).
Multiply the percent of total material passing a number 8 sieve by .3 (three tenths).
Multiply the percent of total material passing a number 60 sieve by .6 (six tenths).
The addition of the results obtained in 004.01, 004.02, and 004.03 will provide the fineness factor of the agriculture liming material.
