Abstract: Manufacturing procedures and compositions for soil enhancers and the like are disclosed. A solution is formed from adding humate to water under constant agitation. Sodium Bicarbonate is added to the solution, resulting in a reaction allowing silica to precipitate out of the solution. The resulting solution is about 12% humic acid. Additional water is added to the solution along with a series of crude protein sources, including fish protein, blood extract, and feather meal. Following the addition of each protein source to the humic acid solution, citric acid is added to increase the protein solubility. Sarsaponins (Yucca extract) is then added to stabilize microbial activity. Additional water is added to the resulting mix, followed by the addition of sugar beet waste lime (calcium carbonate). The calcium carbonate brings the mixture to a pH of about the range of 6.8 to 7.2, which has been found to be encouraging for microbial activity. Seaweed is then added to the mix.

Abstract: We have found an alkaline warewashing detergent composition that can contain a critical amount of a nonionic rinse agent that when used in automatic warewashing machines permits the use of a potable water rinse without the addition of a separate rinse agent. Sufficient residual nonionic surfactant from the alkaline detergent remains on the surface ware and internal machine and rack surfaces after washing to promote adequate sheeting in the rinse cycle. The residual nonionic surfactant on internal surfaces dissolves in the rinse water to create an effective aqueous rinse agent. The nonionic rinse agents can be a single nonionic for both foam reduction cleaning and sheeting or can be a blend of nonionic materials providing these functions. The detergent can be in the form of a particulate, pelletized or block solid.
