Why are we concerned about nutritional quality?
1. The nutritional content of fruits & veggies
has trended downward over the last century
Commercial considerations make "yield" (profit) the primary consideration in breeding and fertilizing
rather than best nutrient content, which is harder to measure
But breeding & fertilizing for "yield" brings reduced nutrition
(See Albrecht Principles)
2. Commercial agriculture, using chemical
NPK fertilizers in excess, leads to:
- Loss of organic matter
- Loss of soil microorganisms
- Loss of top soil
- Water pollution
- Depletion of soil minerals brings reduced nutrition
- Increased vulnerability to pest attack - Truly healthy plants do not attract pests!
There are large variations in the nutritional quality of 'organic' fruits & veggies
Animals living on these nutrient poor foods are not as healthy
Traditional societies living on local, whole, nutrient-dense foods were healthy and lived long lives.
Our modern diet makes us subjects of a giant food experiment, and we are not faring so well, as we suffer from more degenerative diseases at an ever younger age.
6. Varietal differences are
important. - the highest nutrition will be more likely found in heirloom varieties.
- Varietal differences in flavor indicate differences in nutritional content
- More nutritious food tastes better.
- Over history humans unintentionally bred their food crops for higher nutrition, as the families who selected tastier and healthier foods had healthier children. Every family had its own varieties, selected according to the likes of that family. But the children in some families lived to survive the gauntlet of childhood disease while the children in some families died out. The families with higher survival rates had their varieties survive. Thus our food crops were improved.
- Then about 150 years ago plant breeders began selecting our food crops for profit.
Modern hybrids are bred to yield well on depleted soils given modern chemical
fertilizers that do not provide the full range of needed minerals. Hybrids
grow big but do not build essential nutrients as well because of mineral
7. But biggest difference in nutrition comes from the quality of the
William Albrecht was
at the forefront of highlighting this connection between soil and
So how do we tell if we have more nutritious food?
Brix (pronounced 'bricks')
testing reflects nutritional quality
Brix as used here refers to the total dissolved solids in the juice
squeezed out of a plant's leaves or fruit. Distilled water is 0 brix. About the richest brix you will see is 30-35. Although you will hear that
brix measures "sugar," brix actually reflects the total solids - the sum of the sugars, minerals, hormones, oils, amino acids, proteins, flavors, and whatever else. For instance, 100 pounds of 24 brix grape juice would yield 24 pounds of solids. Brix
is measured with an ordinary hand refractometer, which many people call a
brixmeter. See High Brix Gardening
More info on brix

Path to High Brix - Mineral Descriptions

Important points to remember:
- The taste of any fruit, vegetable, or grass gets better and better as the brix increases. Taste reflects nutrition, as the plant has everything it needs to produce maximum nutrition (phytonutrients) as well as sugar.
- The highest brix fruits, vegetables, and grasses keep better - they will dehydrate while their low brix counterparts rot.
- Sucking insects seem to find higher brix plants less tasteful even as higher order animals, like man, find them exceedingly tasty.
- Animals on high brix pasture are much healthier

What is needed for growing topnotch produce - "High Brix levels result when all plant nutrients are available, in an efficient form, to the soil microbes which are responsible for rendering nutrients into a form that the plant can readily use. That translates into a non-labile form of organic nutrient that is at about 6.2 pH and that efficiently feeds a
healthy colony of the right type of microbes in the soil." John Marler See
High Brix Gardening
To reach their full potential to produce high brix results
(minerals) - Although trace minerals are needed in very small amounts, they
may be missing from your soil
In a proper balance
- Too much nitrogen or potassium boosts production, but lowers nutritional value
With adequate carbon
- to hold water, feed SMO (soil microorganisms) and provide backbone of
water of good quality to keep the SMO and plants happy
In an available form
- SMO & humus hold nutrients in an available form
Throughout the season
- (side dressings, nutrient drenches, and foliars) Soluble fertilizers applied
in the spring may have leached away or been bound up by summer
- All essential nutrients
for Fertilizing Organically/Ecologically
- Basic Info
- Carbon - adequate Carbon sources
are essential - organic matter, compost, organic mulch, humates, etc., and
even broken up clean charcoal (biochar). Humates are
produced by the action of soil microbes on organic matter.
Minerals chelated to humic acids are most readily utilized by plants.
- Proper balance of macronutrients
is needed - guided by soil
tests. Some organic farmers claim to
get good results without relying on soil tests, but they are most
likely blessed with good foundational rock to start out with. Others
will never get high brix results because of imbalances that are not
readily corrected by compost, cover crops, etc. It's best to
start out with a soil test to get a better idea of what is needed for
good mineral balance. Here is a good
illustration of why soil testing & amending is useful (note
the difference between the newer plot and the older, depleted plot). See:

- Soil Microorganisms's
- A healthy complement of soil microorganisms are needed to turn organic
matter into humus and chelate minerals
into their most available form.
Maintaining growth throughout the season is
important for obtaining high brix results. It can be done in three ways:
- Feeding the SMO's
- Adequate carbon needed for microorganisms - from CO2, compost, organic matter,
root exudates, humus
- see The Path to High Brix. Sugar and molasses are also
used as quick carbon energy sources for microbes.
- Adequate nitrogen needed for microorganisms:
- Fresh manures (in excess may burn plants), worm castings, oil seed meals, blood meal,
- Nitrogen is fixed by microbes once they are happily fed
- SMO's need adequate water - mulching with organic matter helps to conserve
soil moisture while providing carbon to SMO's
- SMO's need air/oxygen - loosen the soil, cultivate if needed, but excessive
cultivation is hard on the worms and mycorrhizal fungi.
Matter! (Rodale Institute) on how to encourage mycorrhiza in your garden
- SMO's produce good soil structure when minerals and organic matter are
- Plant cover crops to add organic matter and nourish the SMO's. When they
start to bloom, chop them up and work them into the soil.

Nutrition Gardening, by Dr. William S. Peavy & Warren
Peary, 1993, covers much basic information in an easy to

Secrets to Great Soil, A Grower's Guide to Composting,
Mulching, and creating Healthy, Fertile Soil for Your Garden and Lawn, by Elizabeth
Stell, 1998. Good source of basic information, but
beware of chemical fertilizers mentioned. Does not cover use of
refractometer. Minimal info about compost teas. Beware of
instructions for sterilizing soil. Never sterilize good compost,
as the microorganisms in good compost are the best defense
against soil pathogens. I have had little trouble with
"damping off" of young seedlings when my homemade seed
starting soil includes good compost.
The Vegetable Gardener's Bible, by Edward
C. Smith, 2004 This is a lovely book with decent basic information about
gardening, heavy emphasis on compost and misguided emphasis on correcting pH,
rather than supplying the minerals plants need for good growth. You can create
problems if you follow the directions for correcting pH. The book has an
extensive section on combating pests, which shouldn't be an issue if you have
well balanced soil with plenty of trace minerals, humus, and biological
activity. I would not rely on this book for fertility recommendations. It does
have a nice section on individual vegetables and their requirements, including
companion plantings and rotation considerations.
Gardening for Maximum Nutrition, by Jerry Minnich, 1983,
inspired the title of this workshop, but has little information
about building excellent soil, much less the use of a
refractometer. There is much information about the nutritional
value of fruits and vegetables, but it also contains
misinformation, such as promoting soybeans (which contain many
anti-nutrients and should generally be avoided) and low fat
eating (with no appreciation for the importance of fats in the
diet or the excellent qualities of pasture raised animal
products), while equating carotene from plants with the vitamin A
from eggs and butter (the conversion is always very inefficient,
often inadequate, and many people don't make the conversion at
Four-Season Harvest, by Elliot Coleman, 1992, has valuable
info about making compost and extending the season of harvest,
cold frames, etc, but little about building excellent soil, much
less the use of refractometer.
Square Foot Gardening, by Mel Bartholomew, 1981, has
useful info about increasing production in a limited space, and
quite a bit about improving soil quality, but I am wary of his
recommendations to use things like vermiculite, peat moss
(compost, leaves, etc. are better), and wood ashes (easy to apply
too much potassium and throw off soil).
Encyclopedia of Organic Gardening has lots of valuable
basic information, but my 1992 edition has nothing about Brix.

Rateaver, 1993, a large & expensive resource by the
outspoken professor who taught the
"first-in-the-world" course on organic method in
any tax-supported, public institution back in the 1960's,
starting the organic movement in California. This very useful
volume does include the use of brix to evaluate quality.
Books Aimed at Farmers:
These books have more in-depth info aimed at farmers. They spend a lot of time convincing the
skeptic, but less time on practical techniques, leaving the
beginner confused and full of questions. Perhaps that is because high quality
soil fertility is a complex subject, which requires a fair amount of study.
in Agriculture, by Dr. Arden B. Andersen, 2000, explains
much of the science behind soil fertility. Chapter 16, Foliar
Spray Programming, explains the use of the refractometer in field
trials of foliar sprays. See also Dr.

Neptune's Harvest - http://www.neptunesharvest.com/
Harvest fish hydrolysate is an all organic, highly nutritional protein
fertilizer, made utilizing naturally occurring enzymes present in
fresh North Atlantic fish. We produce this using a cold process
employing enzymes (natural biological catalysts) which break down
fish, or fish frames (the part left after the fillet is removed for
human consumption) to simpler protein complexes. This process is
synthetic materials are mixed into the fish hydrolysate, and the only
manipulation the product undergoes is grinding and hydrolysis.
This process yields a stable, non-odorous, liquid fertilizer that is
an easy to use, safe product. The nitrogen in Neptune's Harvest
fish fertilizer is derived from fish protein in the form of amino
acids which when added to the soil, slowly break down into basic
emulsion is made from heated fish waste after protein and oils are
removed. It is an inferior product to fish hydrolysate.

Benefits of Compost Tea
High quality compost tea provides the microorganisms that take the minerals
in the soil and put them in a form that the plant is best able to use, that
is, chelated with humic acids. The microbes, if properly
nourished, turn organic matter into the humic
acids that chelate with the minerals. A good balance of minerals needs to
be in the soil for the microbes and plants to thrive.
High quality compost tea can also provide the minerals needed by the plant
in the chelated form that is easily utilized by the plants. So using it as a
soil drench gets those nutrients to the roots, giving the plant a boost. Using
the compost tea as a foliar puts minerals on the leaves where they can be
utilized, and also protects the plant with a layer of good bacteria. By using
the high quality compost tea regularly you can give the plants a boost to
produce maximum quality (brix). Example
of use of compost tea
As an alternative you can buy inoculants to
add the microbes to the soil - 3 basic kinds - archaea,
bacteria, and myccorhizal fungi, but you have to
be sure to feed the microbes what they need -
organic matter with adequate sugars, protein materials and minerals, and
adequate water. And then mix up drenches or foliars based on recipes in a book
like Beddoe's, Nourishment Home Grown. Or you can buy
special formulas such as Jon Frank, at HighBrixGardens,
uses - there's a list at http://highbrixhome.com/
- see the order form. Michael Melendrez, of www.SoilScreats.com,
has found that adding some humates (presumably because of their available
nutrients) along with the mycorrhizae jumpstarts the formation of more humic
acids from the organic matter, which boosts fertility and improves tilth of
the soil. Worm castings from your worm bed can be a good source of these
humates, as well as lots of microbial action. (back to
The Path to High Brix:
High Brix crops results when crops have high levels of soil
mineral nutrition along with the transformation and chelating agents of soil
acids. Soil acids are the result of the natural deterioration of organic
materials into a tea. The tea is the material that is then transformed
by soil bacteria and fungi into fulvic and humic acids [humus].
The path to high Brix is actually a very simple formula.
Build active humic and fulvic acids in your soil. These are the
acids that chelate minerals, including N-P-K, secondary
minerals such as CA, MG, S, as well as trace minerals, and work
to provide microbes and plants with the chelated minerals.
Fulvic acid is transcellular - it can feed plants by passing
through the cellular structure of the root system. As the
plants accumulate minerals and nutrition - from the fulvic /
humic soil matrix - plants start to build sugars. They also
start reaching towards achieving their genetic potential. As
the plants build mineral content and sugar content, we are able
to read this change with a refractometer. The basis of sugar
increase in a plant is directly related to the nutritional
values available to the plant from the soil in which it grows.
Synthetic forms of nutrients are unable to stick around long
enough to provide plants with the slow nutrient feed that a
plant requires to boost mineral and sugar content. Mineral rich
soils are useless to a plant if there is no transfer mechanism
- the transfer mechanism being the weak acids, in the form of
fulvic and humic acids, that chelate the minerals from the soil
into a form that is useful to the plant.
All organic material will, sooner or later, turn into fulvic
and humic acids [finished compost]. There are several factors,
including pH and a homogenous nature that can accelerate the
transformation. Other factors, such as the labile nature of
manure, condemns most manure applications to being very
ineffective from an efficiency viewpoint in building fulvic and
humic acids. It takes, for example, 6 to 8 tons of manure per
acre to equal a single ton application of a high efficiency
organic fertilizer. Some folks work high cellulose content
mixes into their soil. They are disappointed that the benefit
to their soil does not happen in the year of application. This
is due to bacterial action necessary to break the cellulose
down. [For further elaboration see Producing High Brix
