Ag Lime

Washington State Department of Agriculture (WSDA)
Information Required by the Washington State Department of Agriculture (WSDA) for Registration of Commercial Fertilizer.

The following information meets the labeling requirements of the WSDA for the two waste-derived commercial fertilizers identified above.  

Specialty Minerals Inc. produces inorganic mineral products (precipitated calcium carbonate or PCC) for the paper industry at more than 50 locations world-wide, including three in Washington state.  Specialty Minerals Inc. makes PCC by first combining dry lime (calcium oxide) with water to produce calcium hydroxide.  Specialty Minerals Inc. then combines the calcium hydroxide with carbon dioxide to produce PCC.  After each process, we screen the product to remove large particles. This material is dewatered and stored onsite at our Camas and Longview sites for use as an agricultural soil additive (Ag Lime).  Ag Lime from PCC operations has been used as an agricultural soil additive for more than fifteen years at many of our world-wide locations.

The information provided at this website includes the following:
