02 NCAC 48D .0101          STANDARD AGRICULTURAL LIMING MATERIAL

The standards for liming material comparative classification and labeling are:

(1)           Calcitic Lime or Marl.  At least 90 percent must pass through a 20 mesh screen; At least 25 percent must pass through a 100 mesh screen; Ninety percent calcium carbonate equivalent is considered a standard on which to compare different lots of limestone;

(2)           Dolomitic Lime.  Ninety percent must pass through a 20 mesh screen; Thirty‑five percent must pass through a 100 mesh screen; Ninety percent calcium carbonate equivalent is considered a standard on which to compare different lots of dolomitic limestone.
