Humic Acid 12% W/V in the potassium humate form
-12 is a rich organic (carbon) complex aromatic macromolecules with
amino acids, sugars, peptides, aliphatic compounds involved in linkages
between aromatic rings. The typical humate molecule contains free and
bound phenolic and carboxylic acid groups, quinone structures and nitrogen
and oxygen as bridge units between aromatic structures. Humates are
colloidal in nature. In certain respects they behave like clay minerals.
does Humic Acid Work/Benefits?
Improved water holding and nutrient availability
Humates contain many beneficial chemical groups such as the carboxylic
(-CooH) and phenolic (-oH) groups. It is these with their negatively
charged particles which make humates very effective in chelating with
most of the plant nutrients and importantly water molecules. This is
known as "cation exchange capacity" (CEC). By improving the
CEC of a soil, Humic Acid actually increases the soils ability to hold
more nutrients and moisture for the plant to utilize, which improves
the efficacy of fertilizers.
and retention of nutrients such as nitrogen, phosphorous, potassium
and trace elements (Ca, Mg, Zn, Cu, Mn, Fe, B) in the subsoil therefore
occurs due to reduction in leaching. This leads to improving root mass
in plants and a reduction in the incidence of transplant shock.
greens and brighter reds, longer shelf life and increased sugar levels
in strawberries and sultana grapes occur.
Humic Acid has the ability to lower and neutralize salt levels
due to its composition. Because Humic Acid is such a complex and active
carbon molecule, it will neutralize chemicals that have been over-applied
and as a result are causing plant phytotoxicity. In simple terms Humic
Acid acts as a filter cleansing impurities which contact it. Stabilization
of the soil against strong pH charges from chemical fertilizer applications
Humic substances inhibit indoleacetic acid (IAA) oxidase (breakdown),
thereby hindering destruction of their plant growth hormone. Which can
lead to high activity of IAA and promote plant growth. Humic Acid possesses
auxin like activity which stimulates root initiation.
and physiological process
Humic substances influence several metabolic processes, such as photosynthesis,
respiration, nucleic acid influences, ion uptake and the production
of RNA (Ribonucleic Acid) which is essential for many biochemical processes
in the cell. Humic Acids enhancement of chlorophyll content via foliar
sprays can prevent chlorosis by increasing the uptake of Mg++ and Fe++
Environmental stress damage to plant cells is correlated with the increase
of reactive oxygen species or free radicals such as superoxide, hydrogen
peroxide and hydroxyl radical within the plant. Humic Acid applied as
a foliar enhances the presence of various antioxidants in leaves.
Turfgrass research has shown that Humic Acid foliar applied can boost
photosynthesis, improve growth and development especially when applied
before stresses increase. The tolerance of abiotic and biotic stresses
including disease infection is increased. Thus leading to reduced fungicide
requirement. Making Humic Acid a valuable component of IPM.
For use with agricultural and horticultural crops, fruit trees, flowering
plants and turf.
Humic Acid -12 is formulated to increase your soil's ability to retain
nutrients and improve water-holding capacity. It is suitable for use
with most irrigation systems. It may be used for foliar or soil application
in boomspray or sprinkler/overhead irrigation or for direct soil application
in 12 is a high concentration liquid soil conditioner, which must be
diluted with water before application. It can generally be applied anytime
during the active growing period. For foliar application, apply in early
morning and avoid applying during very hot days. Spraygro Humic Acid
-12 has good nutrient chelating properties, therefore, for best results
apply prior to fertiliser application.
