I have a refractometer for my aquaculture systems. I'll try it on veggies and fruit. Can you explain how the sugar content of food is a measure of its nutritional value?
My wife has been wanting to get a microscope for educational purposes to interact with our granddaughter. This seems a perfect time to combine our efforts and look at our soil. Thank you. Do you have a link for further reading?
Hi Brian, My understanding of how the refractometer works for Brix is that the thicker the liquid the higher the reading.
In turn the higher the reading the higher the nutrient level.
I would not worry that much on how it works, as you have one at hand give it a try.
Go online and download a Brix chart which is a list of fruit and vegetable and their ratings.
Then take a fruit or vegetable which is on the list and squeeze a drop or two of juice on to the
refractometer. Then read the measurement and compare it to the chart.
But before you do the Brix test, you need to do the taste test. Take a bite of the fruit or vegetable and give it you rating.
This will vary from on the low side TASTELESS to high WOW it's flavorsome.
I am going to let you into a closely guarded secret. Our mouth has an inbuilt Brix Meter ;-)
You will see with out fail flavorsome produce will always have a high Brix reading.
All produce I grow goes through the Brix test. That said I am not growing to the required high level yet
but will endeavor to keep improving.
Getting a microscope will open a whole new world to you and can become quite addictive if you are that way inclined.
I have only had a microscope for a couple on months and it has changed my approach to growing.
Hope that helps
