Greensand turns dense, heavy clay into manageable soil. Greensand is a naturally-occurring iron-potassium silicate that can increase soil's moisture absorption by up to ten times.

There are more than 30 trace minerals and nutrients in greensand, with high concentrations of Iron (Fe), Potassium (K), Silicon (Si), Oxygen (O), Magnesium (Mg), Aluminum (Al), Sodium (Na), and Hydrogen (H). These minerals release slowly into the soil in just the proportions that plants need.

Greensand provides a slow and gentle release of minerals, which protects plants from the classic root burn that many stronger fertilizers can cause. Using glauconite greensand as a soil conditioner provides a gentle source of potassium in a 0-0-3 ratio. It can contain up to thirty different trace minerals, all of which enrich the soil and are easy for plants to uptake.

One of the biggest benefits of greensand is its ability to break up clay soils, which increases drainage and allows oxygen into the soil. The exact amounts of greensand garden application will vary depending upon what manufacturer produces the compound. Some manufacturers will add sand to the mixture, which may impact the strength of the product. The condition of your soil will also dictate how much greensand fertilizer is necessary for maximum effectiveness.

Greensand fertilizer is a rish source of glauconite, which is high in iron, potassium and magnesium.  These components are all important to good plant health.  Greensand also loosens soil, improves moisture retention, softens hard water and increases root growth.  Greensand soil ammendment use has been documented for over 100 years.

Greensand must be broken down in soil and is not water soluble. As a general rule, mix 2 cups into the soil around each plant or tree. For broadcast application, the average rate is 50 to 100 pounds per 1,000 feet of soil.

The product is organically certified and the green color from the glauconite helps absorb sun and warm soils earlier in spring. The gritty texture is able to soak up more moisture than garden sand and conserve it for plant roots.  Greensand soil supplement is easy to use and gentle for even the most sensitive plants. Apply in early spring as either a soil amendment or simply a good all purpose fertilizer.
