(1) Liming Materials. Limestone and Dolomite shall be guaranteed as to moisture and the degree of fineness and calcium carbonate, and in addition thereto, dolomite shall be guaranteed as to magnesium carbonate.
(a) Chemical specifications.
1. Standard liming material shall have a minimum neutralizing value of 90% calcium carbonate equivalence (CCE), classified as follows:
a. Standard calcitic liming material shall contain a minimum of 86% calcium carbonate expressed as CaCO3. Any additional CCE required to meet the minimum 90% shall be magnesium carbonate expressed as MgCO3.
b. Standard dolomitic liming material shall contain a minimum of 36% magnesium carbonate expressed as MgCO3. Any additional CCE required to meet the minimum 90% shall be calcium carbonate expressed as CaCO3.
c. Standard calcium-magnesium liming materials shall be those not meeting the above specifications, but with a minimum of 90% CCE derived from calcium carbonate and magnesium carbonate, expressed as CaCO3, and MgCO3.
2. Liming material not qualifying as “”standard””, shall have a minimum neutralizing value of 75% calcium carbonate equivalence (CCE), classified as follows:
a. Calcitic liming material shall contain a minimum of 70% calcium expressed as CaCO3. Any additional CCE required to meet the minimum 75% shall be magnesium expressed as MgCO3.
b. Dolomitic liming material shall contain a minimum of 30% magnesium expressed as MgCO3. Any additional CCE required to meet the minimum 75% shall be calcium expressed as CaCO3.
c. Calcium-magnesium liming materials shall be those not meeting the above specifications, but with a minimum of 75% CCE derived from calcium and magnesium, expressed as CaCO3 and MgCO3.
3. All liming materials shall bear on the application for specialty registration, labeling, and any advertising, the statements:
a. “”Neutralizing value __% calcium carbonate equivalence.””
b. “”This product requires __ tons (pounds) to be equal to one ton of standard liming material.””
4. Hydrated lime shall contain a minimum of 90% calcium hydroxide.
(b) Particle size – Calcitic and dolomitic limestones, except pelletized fertilizer, shall be ground so that:
1. Not less than 90% passes an 8 mesh sieve.
2. Not less than 80% passes a 20 mesh sieve.
3. Not less than 50% passes a 50 mesh sieve.
(c) Moisture content – Calcitic and dolomitic limestones shall contain a maximum of 15% moisture.
(2) Gypsum – Gypsum shall be guaranteed as to calcium sulphate content. Gypsum, calcium sulphate, or land plaster shall contain a minimum of 60% calcium sulphate expressed as CaSO4.
