Greensand works by trapping moisture in the ground at the layer of soil where plant roots feed. The natural mineral coating works like a filter, allowing water to seep in and holding it there until the plants needs it.

A natural silicate that holds moisture in soil at root level

Greensand is a naturally occurring, non-burning aggregate “sand” made of marine potash, silica, iron oxide, manganese, calcium and over 30 other trace minerals. Greensand can be safely stored practically anywhere, and safe to use around people, pets, and wildlife with no waiting period.

Greensand can be used in a variety of applications such as:

  • Vegetable gardens
  • Tree and shrubs
  • Landscaping
  • Lawns
  • House plants  

How it Works

Greensand works because of its manganese dioxide coating. This coating reacts with mineral particles in water and traps them, drawing the water molecules down through the sand and into the soil. The substrate particles form a bond that allows water to seep in where it is held in place, saving it for the plants to use later.

Proper Moisture levels are critical to long term soil health

A proper moisture level is key to maintaining vibrant, healthy plants. In fact, lack of water is the number one factor in reduced yields in commercial farming today. Because root hydration occurs underground, it oftentimes isn’t easy to detect problems with ground soil water levels until they have already begun.

Greensand works to keep soil moisture in the top level of soil, but also in the lower half of the root zone. This deep moisture area serves as a reserve for use when plants are stressed such as harvest time or during dry periods. By helping keep water levels at their optimum condition, Greensand can ensure plants get the proper amount of water they need.

The filtering aspects of Greensand silica supplement are well documented, as it is commonly used as a main component in water filtration devices for home and commercial water wells. Greensand works as an oxidizer to trap unwanted impurities such as iron oxide, and since it’s an organic, naturally occurring material, it’s safe to use in all potable water sources. The filtrating aspects of Greensand can benefit your plants by keeping small amounts of toxins away from susceptible root systems.
