Yosoo Industrial Technqiue Company was established in 2004, is one of the leading manufacturer of Calcium Polysulfide ( 29% Lime Sulfur) in China. Our philosophy is to develop simple and safe products to solve problems in the area of agriculture, home and garden as well as enviromental protection.
Yosoo Calcium Polysulfide ( 29% Lime Sulfur) Liquid is commonly used in Agricultural Applications, Heavy Metal Remediation, and Septic Drainfield Restoration.

1) Agricultural Applications
For use on: Fruit Trees(general), Roses(all types), other Ornamentals and berries
Controls Pests: Two Spotted Mite, Bryobia Mite and Red Spider Mite
Controls Diseases: Scale, Leaf Curl, Shot hole freckle, Rust, Black Spot and Powdery Mildew

2) Heavy Metal Remediation
Yosoo 29% Calcium Polysulfide liquid consisting of multiple sulfur compounds that strongly bond to heavy metals in water. The metal sulfides formed have an extremely low solubility (see chart) and persist as stable solids, which allows for a more environmentally sound disposal. It can be used in wastewater treatment, soil remediation, removal of heavy metals from air emission streams

3) Septic Drainfield Restoration
Septic soil drainfields fail primarily due to a phenonmenon called "Hardpan". Hardpan is caused by sodium (sources of sodium are detergents, soaps, water softners), which bind with soil particles, ultimately disrupting the chemical and physical properties of soil. Calcium contained in Calcium Polysulfide (CPS) removes soil bound sodium (see what causes drainfield problems) and restores permeability of the drainfield soil. The surfactant system is designed to enhance the penetration of calcium polysulfide through complex soil matrix to the site of bound sodium.
