greensand

From: Judy Bauer <jbauer at concordnc.com> on 1998.06.29 at 18:31:56(2379) RE: greensand: A sand or sediment that consists largely of dark greenish grains of glauconite, usually mixed with clay or sand. glauconite - A greenish mineral consisting of a silicate of iron, magnesium, aluminum or potassium found in greensand and often used as a fertilizer or soil supplement. I found the above information from http://www.gardenweb.com under their Glossary of Botanical Terms. I use Mineral Rite which is ground up granite rock. Vulcun Materials has tons of this at their mining site in Concord NC. Mineral Rite contains 75 to 85 minerals: 60% Silica, Aluminum Oxide 15%, Iron Oxide 6%, Calcium Oxide 9%, elemental Calcium, 6.5%, magnesium oxide 3%, Potassium oxide 1.4%, Cobalt 13%, Copper 50ppm, Manganese 6.8%, Molybdenum 5%, Zinc, Chlorine, Boron 10ppm, Para magnetic, elemental sulfur .65ppm. I starting using Mineral Rite in my gardens last year. When tilled into the soil, it is suppose to help increase the earth worm population. I have a couple hundred pounds that need to be put into the garden but it is way too hot. Also it is suppose to improve red clay soils. More mineral info: http://www.pmac.net/rockdust.htm Call your local county extension agent. Perhaps they could be of better help and suggest where to obtain the best greensand/minerals for your soil mixture. Judy Bauer +More Concord NC
