    摘要: A composition including an aqueous solution of calcium polysulfide and an amount of a precipitation preventing compound effective to reduce or eliminate precipitation of the calcium polysulfide at low concentrations. The precipitation preventing compound is selected from the group consisting of sodium hydrosulfide, potassium hydrosulfide, sodium sulfide, and potassium sulfide. A method of reducing or preventing precipitation of calcium polysulfide added to the water in an irrigation system by first injecting the precipitation preventing compound into the water in an amount effective to reduce or eliminate precipitation of the calcium polysulfide at low concentrations. Sodium methyldithiocarbamate can be added to the calcium polysulfide/precipitation preventing compound solution without any substantial precipitation.
