All limestone for agricultural liming purposes shall be crushed or ground to such a degree of fineness that 90 percent of the material will pass through a 10 {2.00 mm} mesh screen and not less than 50 percent of the material will pass through a 60 {250 µm} mesh screen. All such limestone shall also have a neutralizing value of 90 percent calcium carbonate or better.

Basic slag shall be ground open hearth basic slag containing not less than the percentage by weight {mass} of the following ingredients.  P2O5 (Available) ..............2.0 Iron Oxide ...................20.0  Magnesium Oxide ............6.0 Calcium Oxide ..............18.0  Manganese Oxide ............2.0 Neutralizing Value .........55.0 At least 80 percent shall pass through a 100 {150 µm} mesh screen and at least 90 percent shall pass a 50 {300 µm} mesh screen.
