Hi guys! Took a trip to the hydro store to get a couple of things. One was biobizz Root Juice...then I saw the price!
Holy shit! So went home to research a bit. Apparently one main ingredient is Humic acid which you can get a lot
cheaper in powder form.
Does anyone use this to supplement or as an ingredient in compost teas?
Here's some info on what it is:
What is Humus or Humic Acid?
The term "humus" dates back to the time of the Romans, when it was frequently used to designate the soil as a
whole. It was later applied to the organic matter of soils and composts, or to different fractions of this organic matter;
as well as, to complexes formed from a variety of natural organic substances. Humus compounds are complex
natural organic compounds that are formed in soils from plant residues, by a process of "humification". Humus
materials are complex aggregate of brown to dark colored amorphous substances, which have originated during the
decomposition of plant and animal residues by microorganisms, under aerobic and anaerobic conditions, in soils,
composts, peat bogs, and water basins. Chemically, humus consists of certain constituents of the original plant
material resistant to further decomposition; of substances undergoing decomposition; of complexes resulting from
decomposition, either by processes of hydrolysis or by oxidation and reduction; and of various compounds
synthesized by microorganisms.
"Humic acid " is the commercial term often used to refer to the combined humic and fulvic acid content found in these
naturally occurring deposits. Humic acid is known to be among the most bio­chemically active materials found in soil.
Why Use Humic Acid?
Today, there is a recognized and increasing use of humic acids for their beneficial impact on the growth and
cultivation of crops (vegetable & non­vegetable), citrus, turf, flowers, and particularly in organically­deficient soils.
Humic acid is not a fertilizer as it does not directly provide nutrients to plants, but is a compliment to fertilizer. Benefits include:
Addition of organic matter to organically­deficient soils
Increase root vitality
Improved nutrient uptake
Increased chlorophyll synthesis
Better seed germination
Increased fertilizer retention
Stimulate beneficial microbial activity
Healthier plants and improved yields
How Does Humic Acid Improve Soil?
When applied to clay soils, humic acid can help break up compacted soils, allowing for enhanced water penetration
and better root zone growth and development. When applied to sandy soils, humic acid adds essential organic
material necessary for water retention thus improving root growth and enhancing the sandy soil's ability to retain and
not leach out vital plant nutrients.
How Does Humic Acid Improve Plant Growth?
As mentioned above, one way plant growth is improved is through the structural improvement of both clay and sandy
soil allowing for better root growth development.
Plant growth is also improved by the ability of the plant to uptake and receive more nutrients. Humic acid is especially
beneficial in freeing up nutrients in the soil so that they are made available to the plant as needed. For instance if an
aluminum molecule is binded with a phosphorus one, humic acid detaches them making the phosphorus available for
the plant. Humic acid is also especially important because of its ability to chelate micronutrients increasing their bio­
availability.
How Does Humic Acid Effect Microbial Activity and What is its Role?
The activities of beneficial soil microbes are crucial for the sustainability of any soil and plant growth. Humic acid
stimulates microbial activity by providing the indigenous microbes with a carbon source for food, thus encouraging
their growth and activity. Soil microbes are responsible for solubilizing vital nutrients such as phosphorus that can
then be absorbed by the humic acid and in turn made available to the plant. Additionally, microbes are responsible for
the continued development of humus in the soil as it continues to break down not fully decomposed organic matter.
This in­situ production of humus continues to naturally add to the humic acid base and its benefits.

Humic acid is technically not a fertilizer, although in some walks people do consider it that. Humic acid is an effective
agent to use as a complement to synthetic or organic fertilizers. In many instances, regular humic acid use will
reduce the need for fertilization due to the soil's and plant's ability to make better use of it. In some occurrences,
fertilization can be eliminated entirely if sufficient organic material is present and the soil can become self sustaining
through microbial processes and humus production.

Here's some more good info on the different types that are sold. Different sources of humates will have different
ratios of bio active components, something to look out for! I'm still in search of a good, cheap option.
Terminology of Humus­related Materials
Humus­­product resulting from decay of organic matter. Contains both humic and non­humic material.
Humin­­the alkali­insoluble fraction of leonardite. (The usage of this term does not correspond exactly with the usage
by other workers.) .
Humic substances­­(plural) the collective name for the acid radicals found in humic matter. Typically separated from
humic matter by alkaline extraction.
Humic acid­­(singular) the acid radical found in humic matter which is soluble in alkali but insoluble in acid, methyl
ethyl ketone, and methyl alcohol.
Humate­­the salts of humic acids, collectively, or the salts of humic acid specifically. (The usage must be determined
from the context.)
Fulvic acid­­the acid radical found in humic matter which is soluble in alkali, acid, methyl ethyl ketone, and methyl
alcohol.
Fulvates­­the salts of fulvic acid.
Leonardite­­a soft brown coal­like deposit usually found in conjunction with deposits of lignite.
Lignite­­a type of soft coal.
WHY ARE HUMATES IMPORTANT?
Humates are considered commercially available forms of humic matter for use in agriculture, environmental,
industrial, livestock and human wellbeing. Humates are in essence the salts of humic and fulvic acids. Humic compounds make up the bulk of organic matter in
the World’s soils. Through millions of years compaction of plant and animal material, this material can be found
Worldwide. Humic matter comes from a variety of sources including aquatic environments, geologic deposits and
wetlands. Humic matter is also created from agricultural, industrial and municipal activities.
Humates have been used in agriculture for many years, possibly thousands of years by early corn, squash and bean
farmers in the Southwest U.S. In other countries, humic and fulvic acid use has been ongoing for many years with
continual dollars put into research. However, In the U.S. there has been much misinformation regarding the use of
humates, unintentionally spread by suppliers, distributors and marketers who are not scientists and who do not
understand the humate research available (this is also due to lack of uniform testing, which we will go into later). Only
in the last decade or so have we even understood how humates work. We now talk of an auxin­like response, not
really knowing what causes it. It was never realized how effective humate was at very low application rates and how
much soil change it can effect in a short time. Stimulation of biomass production at the bottom of the food chain is a
part of the benefit of humates. Release of essential minerals from the soil for plant uptake is part of this process.
Result of Humate depletion
Humic acids are crucial to life on earth and when they become depleted via oxidation or deactivated by sodium or
aluminum, soil problems develop and can cause negative effects all the way up the food chain. Conditions of soil
depletion resulting in low yield and/or susceptibility to diseases and pests have resulted in devastating effects for
many civilizations of the past. Once humus (organic matter) is depleted, trace element availability along with
phosphorus and calcium availability starts to decline. Anthropologists have observed this in many ancient civilizations.
Human skeletons have shown the effects of deficiencies such as dental problems, osteoporosis and bone
degeneration possibly resulting in many dying at young ages. When zinc is depleted learning ability is lost in the
population along with fertility, and that is the end of that civilization. Analyzing the bone of the “mound builder”
civilization of the U.S. Midwest has proved this. Bones found at the bottom of the mounds were in good health,
whereas those found towards the top of the burials (or the end of the mound builders civilization) teeth and bone
problems were very apparent through analysis of low­level zinc, calcium and phosphorus mineral content. Therefore,
we can learn about mistakes of past civilizations concerning the need for improving agricultural soils through use of
humate product, but are we doing enough in this country to reduce this problem? Other countries of the world are
becoming more and more interested in humates, have completed large­scale research projects in many areas of

humic use and have incorporated use of humates into their agricultural practices with much success.
UNDERSTANDING THE DIFFERENCE
Various forms of raw humus and humates exist including those produced by composting, industrial by­products and
those created during ancient geological events. However, for the purpose of using humates and derivatives including
humic and fulvic acids, we will provide a brief overview of what you, the buyer of products, should understand if you
want the best product for your money. When shopping around, it is in your best interest to know where a company
sources their raw materials, processing methods, their scientific knowledge of the products and scientific research
documents to back their claims. We encourage you to explore this and remember that price is not the most important
factor when deciding on a product. There's a lot of junk out there so buyer beware! What's The Differences?
Leonardite, coal or fossilized peat?
Leonardite refers to slack (oxidized) lignite; typically found in North Dakota, Wyoming and other locations around the
world [the term was first coined by Dr. Leonard at the University of ND]. This exact material has a good amount of
humic, but is lower in fulvic. However, now this term has spread and many people refer to humates in general as
Leonardite. BioAg uses a carbonaceous shale or mudstone. Even in this formation the quality varies according to
geological time of deposit or depth. A couple hundred feet this way or that and you probably have a different quality
of material. Our raw material contains imprints of plants. In basic terms, our humate is fossilized peat from broad­
leaved freshwater plants. Leonardite is salt water reed/sedge based.
Why is this important to distinguish? Bottom line is the bioactivity of the final product (humic and fulvic acid products).
Analysis of various forms of humates from different sources have been conducted. Results show that BioAg's material
contains 12% bioactive fulvic acid based ore whereas true Leonardite contains approximately 8% fulvic acid and high
humic (up to 80%). However, unlike many claim, bioactivity is low...this form of humate material is great for drilling
mud, not for bioactive products.
Similarly, many Chinese and German humates are slack lignite and they recommend 10 times what BioAg
recommends to achieve similar results. Even worse are companies in the Eastern U.S. and many Canadian suppliers
offering coal­based humates; toxic waste products from coal mining that they do not tell you about (See Warning
Below).
2. Form, molecular weight and biological activity
The best humate is one that is high in biological activity, fulvic/humic acids, silicic acids and also high in oxygen in the
phenolic and quinoid groups. Humic acids function best in the low weight fraction (fulvic) on the cellular level.
Molecular weight is very important with the high oxygen types usually falling into the low weight (smaller sized
molecules) category and thus more biologically active since only low weight molecules are utilized by beneficial
organisims, enter cell membranes more efficiently, create greater permeability for the flow of nutrition into the cell
and adsorption of excess heavy metals for removal from the cell. In agriculture, stimulation of each cell produces
more energy from the plant and higher yield. The process starts with soil microbes, then plant root cells and
eventually the entire plant. We can also do this by foliar spraying soluble fulvic acids and adding a humic solution to
the soil at planting. Cellular stimulation at all levels is how it works. 3. The Bottom Line & Results?
This is an economic issue, boiled down to how much humic acid is one getting per dollar and what is the cellular
stimulation level? Consider the fact that the more concentrated a humate product the cheaper it is to transport and
apply. Therefore, the most concentrated source is the best buy due to transportation costs alone. Let's take a look at
raw humate (before it's solublized and concentrated). A high­grade raw humate might be very effective at raising the
yield by 20% or more with just 50lbs per acre of a 70­80% humic acid material. A humate of 34% humic requires
250­300# per acre of raw material to do the same job. What is the price, what is a pound of humic acid delivered
going to be with current freight rates? Get your calculator out!
A company claims to have the highest guaranteed humic acid available at 35% humic acids, 35% carbon and 35%
organic matter. Is this the highest guaranteed humic material when another company has a product guaranteed at
80% humic acid and one in Washington State has one guaranteed at 70%? Is this misinformation? Consider the
standard source of humic acid provided by many suppliers and their distributors­Leonardite, which contains over 80%
humic acids. On the surface, this would seem to be the highest. However, this is not the most effective unless it is
made into a soluble form where it becomes effective at low rate and the humic acids of the soluble powder can be
over 80%. It is also low in the fulvic portion, the bioactive portion. These claims are often misleading, and not the
fault of any one company, but a result of lack of testing standardization in our industry. Humates are valuable
products, and until our industry can agree on some forms of standardization, only deal with companies with a track
record and a proven high­grade product.

dealers :D
£9+ del for 1ltr of canna organic ph down (40% citric acid). OR.. £5 inc del for a kilo of citric acid crystals and £2 for
a ltr of distilled water, and make an 80% solution for £2 p/ltr.
£18+ del for biobizz professional soil that lacks magnesium. £5 for tomato compost and £1 for epsoms salts.
I could go on :D
Does anyone use this to supplement or as an ingredient in compost teas?
I haven't added it in a separate form before now because of my nutrient selections, but it's pretty much found in all
good fertlisers, soil and other additives so it's well recognised as a good thing by the big boys.
Cheers for posting the info I found that useful to get a few bits from.
