How to Use a Refractometer?

All blueberries are not equally nutritious! The refractometer may be used to measure and compare the health/quality of fruits and vegetables. Compare the produce purchased from local stores or farms to be sure you are eating the best quality foods. Compare organic with non organic or GMO foods. Monitor the quality of the foods grown at home year after year. This simple tool may also be used to determine the efficacy of the home made amendments applied in the garden. No batteries required and at relatively low cost ($35) makes this an easy way to better understand fruit or vegetable health/quality. Visit us at Nigel-Palmer.com for information about mineral amendment analysis, upcoming workshops, podcasts and other educational opportunities. For mineral and biology amendment recipes that you can make at home for free or low cost that close the waste gaps check out my book "The Regenerative Grower's Guide to Garden Amendments" available from Chelsea Green Publishers.

    Thanks a lot for this simple excellent explanation. I will get a refractometer and use it on my plants and see what extractions (from your book) make them 'happy'.

    Nigel, I'm very excited about the material you're presenting, thank you! I've been studying John Kempf and Elaine Ingham while looking for simpler, less expensive, local strategies to build my soil life and achieve resilience on my permaculture project. This bridges the contradictions and closes the loop in my search. Can't wait to make these preparations and test the results. Kudos!

    Do you only use plants with a high brix reading before making your fpj? For example if my tomatoes have a lower brix quality would it not be ideal to use that plant for making fpj? Maybe your book answers that question. I'm anxiously waiting for it to arrive.

    Since the refractometer measures sucrose, it is measuring sugar carbohydrate. There is no known need for carbohydrate in the human body. So why is it implied that higher sugar plants are more nutritious? Is there any way to measure vitamin or mineral density in food?

    The refractometer is the cheapest, easiest tool to date for these purposes, originated for the wine industry over a hundred years ago and used in many other industries today. There is much info on line to support this discussion.Yes, there are tools on the market to measure nutrient density of produce that take the concept of the refractometer to a higher level. They are relatively new and not cheap yet, but costs ae coming down.

    If you measure the leaves instead of the fruit, you will get more accurate reading in terms of minerals. you will see, that leaf reading will go up as plant health improves, which you can tell just by looking. It is disolved solids, not sugar, that brix measures. It includes sugar, but also minerals and proteins, not sure about fats.

    DIY Life has a good answer, but in regards to sucrose, we don't use it directly but the beneficial bacteria in our guts do and in turn secrete many of the vitamins we need. Most of our B-vitamins don't come directly from our food, they come from the bacteria that break down the things we eat. Other things are broken loose from more complex molecules by the bacteria and made more bioavailable to us.

    The plant uses all the fpj constituents and distributes the products through the phloem sap flow throughout the plant. See mineral analysis of fpj and other recipes in appendix E of book. This is not cheating, but feeding the plant.

    so, sugary FPJ is taken in by the plants and their leaves, buds and fruit will be sweeter/richer. Because we're not eating the sugar directly, the sugars in the plant parts we eat are complex carbs...yes? Is this a true statement? thanks

    During fermentation the sugar is consumed by the biology on the plant surfaces. This is evident by the smell of the final product which may smell like miso or alcohol or something along these lines depending on ratios, time for fermentation and other factors. The final fpj product has many constituents, building blocks, which plants use to increase the % sucrose of their sap as measured by the refractometer. I have focused analysis on the mineral content of these products as this is relatively easy to measure and revealing. You can see this mineral analysis on my web site or in the appendix of my book.
