ABSTRACT:
Aqueous thiocarbonate solutions are stabilized by the addition of base, sulfide and/or polysulfide, and the stability and safety of the more concentrated solutions containing 1 weight percent or more equivalent CS.sub.2 as a thiocarbonate are achieved as reflected by significant reduction of CS.sub.2 partial pressure in such solutions. Also, deposit formation in irrigation systems delivering such thiocarbonates, such as drip emitters and sprinkler heads, is reduced or eliminated with minor amounts of sodium hexametaphosphate.
