Rock dust is fine particles of rock or stone. Many varieties of stone have been tested and have proven to produce amazing results as soil and plant enhancers. The stone is crushed until the particles are very small. These particle are measured by grades of a seave. A seave is like the screen on your windows but come in verious sizes. Seave sizes are determined by the number of openings per square inch. The size of grain of material that will pass through a particular seave determines its rating.

Different size rock dust has different life spans of effectiveness to the plants that are nourished by it. Smaller particles disolve quicker than larger ones but are very effective. Larger particles of rock dust disolve the outer layer through time while enhancing the plant for a longer time period. The most important factor in rock dust is the degree of fineness of the rock dust. The finer the rock dust is, the more easily soil bacteria decomposes the dust particles and releases the trace elements contained with them, putting the trace elements into a form which the plant roots can absorb.

This rock dust is formed from Limestone quarried in Southern Indiana USA. the major use for limestone is building panels because of its endless wear factor.Crushed stone for road beds are from limestone. The Empire State building is covered with limestone from Indiana

See the Limestone Institute for more on limestone
The stone is quarried from the ground. Then cut into chunks sometimes as large as a school bus, sometimes smaller. The large stones are for building panels while the smaller one are selected and graded for size and hardness. Some stones are then run through a crusher and makes little rocks out of big ones. As these stones are shattered into smaller pieces, tiny particles are broken away also. The stones are run through a screening process. Each screen gets smaller until the holes in the screening procees is smaller than the holes in a modern screen door. The smallest particle are used for aglime.

< My very own personal experience! In 1994 we built a new house. I had heard stories about the benefits of rock dust but seriously questioned their authenticity. A friend had shared his experience of success with me, so I experimented. During excavation for the new home, I intentionally left one area bare of top soil for a garden spot. All that was in this area was yellow clay. Solid clay. I applied rock dust from a stone mill at the rate of one hundred ton per acre in the fall and tilled it in. Much to my surprise, the soil looked very dark in the spring and grew a very nice crop of vegatables. That was twelve years ago and it is still producing. This barren clay was revitalized in only one winter and I was amazed. Yes the application was quite intense but the results were also.
