Rock dusts have amazing potential as a
soil amendment, but which one is right for your soil?

Every garden's soil composition is
different, lacking in essential minerals and nutrients while rich in
others. The same disproportion is true of rock dusts. Southern Maine
is very geologically diverse, and our local quarries collect and sift
the fine tailings from their crushed stone products, resulting in diverse
rock dust with different mineral profiles from one quarry to another.

By collecting and analyzing samples of
rock dusts from local quarries, I will create a database of the
minerals available within a given quarry's rock dust. The database will be freely available online. Using this
database, local gardeners will be able to cross-reference the results
of their own garden's soil test results to determine which quarry's
rock dust is the best match for their needs.

The majority of the funds raised here will go towards testing samples at Logan Labs LLC, a $25 test from the lab will give these data points for each source:  pH,Total Exchange Capacity, Sulfur, Phosphorous, Calcium, Magnesium, Potassium, Sodium, Boron, Iron, Manganese, Copper, Zinc, Aluminum, Molybdenum, Cobalt, Silicon, Selenium and % Base Saturdation Ca, Mg, K, Na. Some funds will be needed for acquiring samples, packing and shipping samples and possible extra testing. I hope to test samples from 10-15 sources.If you want to help in ways other then donating, or in addition to donating, you can help spread the word by linking to this page on facebook or other social media and by alerting me to rock dust sources i may not know of. Of course if you have already tested a local rock dust and can share the results that is very helpful as well.
