Where can I find the microBIOMETER® testing instructions?

The testing instructions along with built in timers are now included directly in the app for easy viewing. You can also download and print them here or watch our video tutorial here.

How can I interpret my microBIOMETER® test results?

Our Understanding Your Results page features a microBIOMETER® range chart for microbial biomass as well as a plant succession ladder for optimal fungal to bacterial ratios for different vegetation.

How can I access my microBIOMETER® data on the web?

Each time you run a test for microbial biomass and fungal to bacterial ratio using microBIOMETER®, our phone app stores the results and location of where the test was taken in our web portal. This guide will help you understand how to see your test results, how to edit sample data including changes to location and name, how to add data points, and how to access all this on the web and export to Excel for higher level analysis.

What is the maximum interval between sampling the soil and testing?

If stored in a plastic bag so it can’t dry out, you can wait up to 72 hours. If more time is needed, refrigerate the samples for up to a month.

Can I measure microbes in soil that has charcoal or biochar?

This had been tested and biochar can interfere in the microBIOMETER® test. Soil treated with biochar more than 6 months ago does not appear to be a problem, but the biochar in freshly treated biochar soils can lead to falsely high readings.

Do particles in the sample window affect the reading?

Yes. When you draw up the microbes in the pipette, be careful not to get any of the floating debris at the top of the tube in the pipette. We advise tapping the tube 5 minutes into settling as per our instructions to precipitate the floating debris so it won’t interfere with the measurement.

What is the maximum interval between whisking and placing the drops onto the sample window?

20 minutes is ideal. Longer than that and your reading will start to decrease as eventually the microbes begin to settle to the bottom.

Can I use my own soil sifter or do I need to use the sifters included with the test kit?

You can use your own soil sifter to perform the test as long as the holes are 2"-3"mm.

What happens if the test card gets wet in the area around the sample window?

The app uses the areas surrounding the window to compensate for differences among phones and lighting conditions. It’s best to wipe off any liquid on the calibrating grayscale surround.

Can I write on the test card?

Yes, but be sure not to get too close to any of the printed lines and shapes surrounding the sample window.

Would microBIOMETER® work with a coco based medium mixed with petites and clay pellets?

If you use a coco based medium you need to ask us for the filter version of our soil test. The filter version contains a plunger that pushes any floating particles down and allows only microbes to rise to the top for sampling.

If I left my microBIOMETER® in a cold shop for an extended period, are the kit products still good?

Yes, the cold temperatures will not effect your microBIOMETER® and supplies. They are perfectly fine to use.

Can I use microBIOMETER® to check the volume of microbes in my compost tea?

Yes, you can. microBIOMETER® can be used to test soil, compost and compost tea.

Is it imperative that I use distilled water when using microBIOMETER®?

It is not imperative to use distilled water. We don’t discourage it, but it isn’t necessary. Using tap water won't skew or invalidate the results.

Can I test soil in areas with poor cell service?

Yes, you can. The app will save the data to your device and sync with the cloud next time it has internet access and the app is started.
