does anyone ever use marl as a buffering agent?

From TMC:

"Marl: Dredged from lake bottoms, marl is a soft lime similar to chalk but has the consistency of clay. It is a composite of clay and calcium carbonate with good water holding capacity."

marl : "soil, essentially clay mixed with carbonate of lime, highly valued as a dressing or fertilizer. It crumbles rapidly and easily. Marl in which the lime is in the form of invertebrate shells is called shell marl. The term is loosely used for a variety of soils, some of which are low in lime content, e.g., the greensand marl of New Jersey. Marling of soil tends to lighten it, correct acidity, and promote nitrification."

you got your quote from TMC, so yes it works. whether anyone does is up for grabs, as there are better ingredients easily available. i wouldn't bother, as i can get peat, coir, verm, oystershall, and chalk. otherwise i wouldn't know what was in the 'marl'. i like my casing layer to be non-nutritious.

sorry to sound like a dick - i am a dick, you see  :laugh:

Driving to a source of marl is as far as the drive to acquire buffalo dung.  Only snow may inhibit any fun.  :\

I am curious enough to experiment, seeing as no one has.  Sterilized marl may have an interesting impact on results.  :wink:

I just picked some up, sounds like a great product, will post back some results as they come, do a search for "Lithothamnium" or "maerl"

also sounds awsome for the garden.
