Leprino Cheese Brine (LCB) was approved for use in field trials at two locations in Colorado as a pre-wetting agent added to solid material (salt-sand or rock salt) at 8 gal/ton. Three attempts were made to pick up and then apply the LCB as a pre-wetting agent. While one successful pick up and application occurred, it was not as a pre-wet. The two
