What Are the Benefits of Greensand?

Water Purification

• When installed as the media in a filter bed, greensand is used to purify well water. Greensand removes iron, manganese and hydrogen sulfide and their associated unpleasant odors from well water. Removal of these compounds also prevents the mineral staining of sinks and other fixtures, as well as clothes in a washing machine.

Soil Conditioning

• Greensand absorbs one-third its weight in water, making it 10 times more absorbent than standard sand. When added to soil, it loosens heavy clay and binds loose, sandy soil. As a potting material it significantly reduces the need for watering.

Mineralization

• Greensand contains a wide variety of trace minerals. The gradual, long-term release of minerals into the soil, known as mineralization, enhances the taste, color and nutritional value of plants.

Potassium Deficiencies

• Due to its high potash content, greensand acts a slow-release, insoluble source of potassium. To correct potassium deficiencies, greensand in amounts ranging from 800 pounds to 4,000 pounds per acre may be applied.
