Humic Acid

Humic Acid comes entirely from vegetation which was laid down in the Carboniferous Period . Millions of years ago, earth's mineral-rich soils produced a profusion of lush green forests, succulent fruits and vegetables.
As this lush growth of vegetation died, it accumulated and later, was buried by rock and mudflows and deposits of sand and silt. The weight of these deposits compacted and compressed out all of the moisture.
Over the ages, the vegetation underwent compaction and heating. It slowly carbonized and became coal.
This compaction squeezed out the organic acids and esters present in the vegetation and formed a pool on top of the lignite coal bed. This pool dried and aged and eventually formed Leonardite shale. What remains today is a deposit of dried, prehistoric plant derivatives.
During this process simple products of decomposition: amino acids, carbohydrates and phenols, turn into very complex products - Humic Acids.
Because of its vegetative origin, this material is very rich and beneficial to plants today.
In natural conditions humic acids are not soluble. It is a reaction of nature, otherwise soils could be deprived of humus and washed out to sea.
Humates are the salts of humic acids, which form complexes with phosphorus and micro elements which are easy assimilated by plants, and sharply increase efficiency of mineral fertilizers.
Humate materials are widely distributed organic carbon containing compounds, found in soils, fresh water, and oceans, and make up approximately 75 percent of the organic matter that exists in most mineral soils. Humates play a direct role in determining the production potential of a soil.
Quality: Not all the products on the market under the name Humates are of a high quality.
There are several different chemical structures of Humic Acid. The more concentrated forms are the best and in the long run, and can be the cheapest.
The first, is fossilized brown oxidized lignite or Leonardite. This product has 30- 40% humic acid content, 30-40% of mineral part -ash, and the balance is presented by unknown ballast substances. Recommended application norms of these products are very high, because humic acids in them are insoluble and are not in an active form. Mineral content of these products have metals which bind to humic acids. Long time usage of these products pollutes the soil.
The second group is produced in the common method of treatment of lignites with concentrated alkalines. The content of Humic acids of these products is within the level of 20-30%. Humates here are in active form, but they still have a high content of ballast and ash, which causes above mentioned problems.
The third group of Humates is produced in the way of treatment of brown lignite or Leonardite with alkaline solutions. These Humates are high quality products, because they are free from ballast, but they are very expensive and difficult to transport and handle. Moreover the production process leaves a lot of waste.
The fourth group are Humates produced from a high quality tested lignites, with 70% humic acid content, 12% mineral ash part and 18% organic ballast. These soluble products are in powder form with 75-85% of Humic acids.
Only two products meet those requirements; these come from East Siberia, Russia and N.W. New Mexico; these are freshwater deposits and have the highest percentage of low molecular weight humic acids, generally referred to as Fulvic acids.
Fulvic acid is the acid radical found in humic matter which is soluble in alkali, acid, methyl ethyl ketone, and methyl alcohol. Fulvates are the salts of fulvic acid.
Both fulvic and humic acids found in soil, result from the chemical and biological degradation of dead organisms. Fulvic acids provide multiple and natural chemical reactions in the soil, instigating positive influences on the plants' metabolic processes.
Fulvic acid is especially active in dissolving minerals and metals when in solution with water. The metallic minerals simply dissolve into ionic form, and disappear into the fulvic structure becoming bio-chemically reactive and mobile. The Fulvic acid actually transforms these minerals and metal into elaborate fulvic acid molecular complexes that have vastly different characteristics from their previous metallic mineral form. Fulvic acid is nature's way of "chelating" metallic minerals, turning them into readily absorbable bio-available forms.
Fulvic acid readily complexes with minerals and metals making them available to plant roots and easily absorbable through cell walls. It makes the actual movement of metal ions that are normally difficult to mobilize or transport. such as iron, easily transportable through plant structures.
It allows minerals to inter-act with one another, breaking them down into the simplest ionic forms, chelated by the fulvic acid electrolyte. Fulvic acid is a natural organic electrolyte.
An electrolyte is a substance that is soluble in water or other appropriate medium that is capable of conducting electrical current. Fulvic acid has proven to be a powerful organic electrolyte.
Fulvic acids also dissolve and transpose vitamins, coenzymes, auxins, hormones and natural antibiotics that are generally found throughout the soil, making them available. These substances are effective in stimulating even more vigorous and healthy growth proceeding certain bacteria, fungi, and actinomyceles in decomposing vegetation in the soil.
It has been determined that all known vitamins can be present in healthy soil .
Plants manufacture many of their own vitamins with those from the soil further supplementing the plant. Upon ingestion these nutrients are easily absorbed by animals and humans, due to the fact that they are in perfect natural plant form as nature intended.
The majority of research and experimentation on fulvic acid, has been done in relation to plants. Yet humans have been ingesting fulvic acid complexes regularly for over 60 years in supplemental form, and for thousands of years from natural food and plant sources.
Testimonials continue to show that the beneficial properties relating to plant and cell studies, hold true in relation to animal and humans as well.

About Soils

Soils are derived from weathered parent material. If the original material was low in a particular element or non existant, so too is the resulting soil.
Soils can become depleted of minerals and trace elements which too are absorbed into the likes of meat, milk, bone, wool, vegetables and fruits, as well as the major elements, and many soils are naturally deficient in one or more of these elements.
Within a space of just a kilometre or two, soils can be radically different, with.localised deficiencies of trace elements like copper, cobalt or selenium.
Because our supply of minerals comes through the food chain, from the plants and animals we eat, and because these same minerals are essential ingredients of these same plants and animals, any that are missing can have serious implications for plant, animal and ultimately our own health.
One has to conclude then, that this is where fertilization should start.
Even though the major element solid type NPK fertilizer is required in the largest amounts, if used exclusively, sooner or later a deficiency of a minor element can occur in soils low in that particular element, and it too should be replaced.
Foliar nutrients can quickly correct a nutrient imbalance, and are by far the most effective way to apply micro nutrients or trace elements and supplement the major elements , because foliar nutrients are readily available and more easily utilized by the plant than soil nutrients.


We often see quotes by various agricultural sources in NZ, the amount of the likes of phosphorus, sulphur and calcium that are removed from the soil in meat, milk, bone and wool.
This, illustrates the importance of replacing these elements as they go out the farm gate, with the likes of superphosphate, which supplies phosphorus and sulphur.
Tissue studies of plants have found more than 60 different mineral elements, although it has generally been accepted that 16 -17 elements are essential for plant growth.
Many farmers in NZ are well aware of the consequences of low levels of copper or cobalt in pasture, and in some areas selenium, as well as magnesium (grass staggers), even iodine and zinc and in many cases calcium (as in milk fever).
There are many cases where several of the nutrients are missing or are at such low levels that supplementation of the animal is necessary, otherwise the animal would die or be severely undernourished.
Subclinical trace mineral deficiencies occur more frequently than recognized by many livestock producers and can be a bigger problem than acute mineral deficiencies, because the specific symptoms that are characteristic of a trace mineral deficiency are not seen.
Instead, the animal grows or reproduces at a reduced rate, uses feed less efficiently and operates with a depressed immune system. The end result is inefficient production and lower profitability.
When micro-nutrients become a limiting factor, water, fertiliser and other high-energy production inputs are wasted.
In most cases the elements needed by the plant are also needed by the animal which feeds on the plant.
Some elements needed by the animal are not required by the plant, but plants takes them up and makes them available to the animal, and therefore plays a significant role in animal health. Selenium, iodine and cobalt are examples.
Seven trace minerals, have been shown to be needed in supplementing animal diets. They are iron, copper, zinc, manganese, cobalt, iodine and selenium.


What is a chelate?

Chelates are organic molecules that can trap or encapsulate certain highly reactive trace metal cations which prevents them from entering into unwanted chemical reactions and forming insoluble compounds, which are unavailable.
Chelates incorporate metal ions into a soluble but bound form, to make them available to the plant because they are very soluble in water.
Chelation is bonding the metal ion to an organic molecule, making the metal ion highly soluble.
A chelated form of a mineral has different qualities from the mineral itself. One quality that can change is bioavailability; the ability to absorb and use the mineral.
Bioavailability can be increased or decreased depending on the mineral-chelate complex formed.
Some synthetic metal-chelate complexs form extremely strong bonds and bind minerals so tightly that they are unavailable for their physiological functions, and if used in foliar fertilizer has a great deal of trouble releasing the metal ion once in the plant.
Metal-chelate complexes used in foliar fertilizers need to form bonds strong enough to protect them from unwanted chemical reactions but once in the plant should release easily.
Natural chelating agents do not share the problems of the synthetics and are state-of-the-art technology for delivering selected mineral and trace elements with maximum bioavailability, tolerability and safety
If a yield-limiting deficit is suspected or established then the chelated mineral applied as a foliar will address that deficit more accurately and with greater speed than any other nutrient.
These elements are far more easily absorbed by plant roots and leaves in this chelated form because of changes in the electrical charge from the trace minerals as a result of their organic encapsulation.
The chelation process removes the positive charge from the metals, allowing the neutral or slightly negatively charged, chelated molecule to slide through the pores on the leaf and root surface more rapidly.
These pores are negatively charged, so there is a problem with fixation of positively charged minerals at the pore entrance.
There is no such restrictive barrier for the neutral, chelated mineral.
