Claim:
1. A process for making a composition comprising a biologically active polyelectrolyte enhanced biopolymer, the process comprising: (a) contacting an alkaline liquid with a composition comprising humic substances, thereby making a liquid extract enriched in humic substances and a particulate depleted of humic substances; (b) adding sodium silicate and sodium carbonate to the liquid extract enriched in humic substances while the liquid extract enriched in humic substances is being stirred continuously and is being cooled from a temperature of from about 72° C. to about 80° C. to a temperature of from about 45° C. to about 50° C., thereby making a salt-treated extract; and (c) adding a catalytic amount of one or more acids to the salt-treated extract, the catalytic amount sufficient to catalyze polymerization of humic substances in the salt-treated extract, thereby making the composition comprising the biologically active polyelectrolyte enhanced biopolymer.
