"Greensand is a sand or sediment that consists largely of dark greenish grains of glauconite, usually mixed with clay or sand.
Their are three main places that mine Glauconite (greensand) in the United States, they are New Jersey, Texas and Arkansas.
It is a natural mineral that opens up tight soil and binds the loose soils.
Greensand is mainly potash and a hydrated silicate of iron.
It releases it's nutriential benefits through a exchange action in the soil to be taken up by the plants.
The mineral has been used for decades which contains a huge amount of Potassium and other trace minerals(as many as 30).
The Jersey greensand contains 20% iron oxide and 7% Potassium(Potash).
The ancient sea deposit is a slow release of Potash and the other essential minerals.
Since the 1700s greensand has been used as a fertilizer and soil conditioner that loosens clay soils and also increases the water holding capability of the sand and clay, when added to any soil will increase water holding properties.
Texas greensand also known as glittergreen holds pretty much same properties as New Jersey greensand.
Potassium and iron soil supplement recommended for a mulch, conditioning additive or top dressing. It slow releases nutrients, loosens soils and holds water.
In Arkansas greensand is found in Nacatoch and Ozan formations, which extend from the Arkansas-Oklahoma border to Arkadelphia.(?)
Here the glauconite is in a sandy marl that can be 2-10 feet thick and be as pure as 50%.
Marl is defined as
"A crumbly combination of limestone and clay that may be added to deficient soils."

Greensand is non-soluble in water but will not burn plants.
Safe to handle and is odorless...
Now if anybody would care to describe how they have used greensand succesfully before, or maybe organic soil mixes/ recipes that incorporate greensand, this would be a good place to post ones thoughts.
I have never used greensand before and would be interested in hearing the pros and cons (noticeable benefits?) on the subject of Greensand in organic style potting soil mixes.
