I have been weighing the options of testing soil in the field vs. on the bench for parameters of interest. The parameters I am focusing on are soil ph, temperature, moisture, fertility, conductivity and organic content. Of these seven, only temperature and moisture must <\/i>be collected in the field. I believe that the others can be more accurately determined in a bench-top environment. I am developing my hardware designs accordingly. The next steps for me are to track down materials to build this<\/a>\u00a0ph probe and figure out how to interface it with an arduino board and relay information back to the field science android app through bluetooth. I am also planning to have a conversation with Mike Deibel this week about using optical measurements for organic content and fertility tests (and possibly munsell color tests). I also have a back-burner interest in geophysical surveying techniques for archeological dig sights that is still very much in the research stage.<\/p>\n","protected":false},"excerpt":{"rendered":"
