Typically *one* pays $60-$80 to have
soil tested. You supply about a pint or two of soil, and send it off for
analysis. 10 days later you get the results.

I watched a Mars Phoenix segment of scienceNOW last week. At one point,
they were showing something of an analysis of soil here on earth with
something like a vial of some ingredients that would test soil for the %
of various chemicals like calcium, nitorgen and potassium. The vial had
color markers on the side, and looked smaller than a common test tube.

Where does one get these devices? Typically when pays $60-$80 to have
soil tested. You supply about a pint or two of soil, and send it off for
analysis. 10 days later you get the results.

I contacted Phoenix. It was a common garden sampler.
