Biosolids are an or­ganic amend­ment avail­able to gar­den­ers. Ac­cord­ing to the United States En­vi­ron­men­tal Pro­tec­tion Agency, biosolids are care­fully treated and mon­i­tored resid­u­als formed at sewage treat­ment fa­cil­i­ties. They may be re­cy­cled into fer­til­iz­ers to stim­u­late plant growth. Biosolids may help re­duce the need for chem­i­cal fer­til­iz­ers. Biosolids can be safe to use, but home­own­ers should be cau­tious about heavy metal con­tent, pathogen lev­els and salts. Rely on only Class A biosolids, which have been treated to re­duce the bac­te­rial con­tent and are ap­proved for use in pro­duc­tion agri­cul­ture. Home gar­den­ers may want to avoid biosolids in veg­etable gar­dens be­cause of the po­ten­tial for heavy metal con­tent seep­ing into the pro­duce.
