Soluble Organic Humic Acid Fertilizer Soil Conditioner Potassium
Humate Powder for Plants
Product Introduction
Soil humic acid is innate and mainly a mixture of a special type of
macromolecular organic compounds formed by plants under the action
of microorganisms. Coal humic acid is a mixture of a type of
macromolecular organic compounds formed after the decomposition and
transformation of plants by microorganisms and through long-term
geochemical processes.
Classification of humic acid
Classified by molecular weight, it can be divided into three
categories:
(1) Humic acid: The part of humic acid that dissolves in alkali but
not in acid is called humic acid.
(2) Humic acid: The part of humic acid that is insoluble in both
alkali and acid is called humic acid.
(3) Fulvic acid: The part of humic acid that is soluble in both
alkali and acid is called fulvic acid.
Among them, the most active one is fulvic acid, and its effect on
increasing crop yields is also the most obvious.

Humic Acid Applications
① Stimulate physiological metabolism
Humic acid contains a variety of active functional genes, which can
enhance the activities of catalase and polyphenol oxidase in crops,
stimulate physiological metabolism and promote growth and
development. For instance, humic acid can prompt seeds to germinate
earlier, with a high germination rate, especially at low
temperatures. It can stimulate the division and growth of the cells
in the extreme meristematic tissue of the root system, enabling the
seedlings to develop roots quickly, with more roots, increased root
mass, and elongated roots, thereby enhancing the crop's ability to
absorb water and nutrients. Therefore, with an adequate supply of
nutrients, the crop stem blocks are strong, the branches and leaves
are lush, photosynthesis is enhanced, the transfer of nutrients to
the fruiting body is accelerated, and the fruit is promoted to
color and mature earlier.
② Alter the characteristics of chemical fertilizers
Humic acid contains functional groups such as carboxyl and phenolic
hydroxyl groups, and has a strong ion exchange and adsorption
capacity. It can reduce the loss of ammonium nitrogen in ammonium
bicarbonate and improve the utilization rate of nitrogen
fertilizer. Nitrohumic acid that has been oxidized and degraded can
inhibit urease activity and reduce urea volatilization. Degraded
nitrohumic acid increases the distance that phosphorus moves in the
soil, inhibits the fixation of water-soluble phosphorus by the
soil, converts available phosphorus into delayed phosphorus, and
promotes the absorption of phosphorus by the root system. Humic
acid can undergo chelation reactions with insoluble trace elements,
generating humic acid trace element chelates with good solubility
that can be absorbed by crops, which is conducive to the absorption
of trace elements by the root system and leaves.
③ Improve soil structure
Humic acid can promote the formation of soil aggregate structure,
regulate soil pH value, adjust the conditions of soil water,
fertilizer, air and heat, increase soil exchange capacity, achieve
acid-base balance, enhance soil water and fertilizer retention
capacity, promote the activity of soil microorganisms, increase the
number of aerobic bacteria, actinomycetes and cellulose-decomposing
bacteria, and accelerate the decomposition and transformation of
organic matter. Promote the release of nutrients and facilitate the
absorption of nutrients by crops.
④ Enhance resilience characteristics
Humic acid can reduce the opening intensity of stomata on plant
leaves, decrease leaf transpiration, thereby lowering water
consumption, improving the water condition within the plant,
ensuring the normal growth and development of crops under drought
conditions, and enhancing drought resistance. Humic acid is mostly
an amphoteric colloid with high surface activity. It has an
inhibitory effect on fungi, can enhance the cold resistance of
crops, is easily adsorbed by cell membranes, changes the
permeability of cell membranes, promotes the absorption of
inorganic nutrients, prevents rot and root rot, and reduces pests
and diseases.
⑤ Improve the quality of the seeds
Humic acid can form complexes or chelates with trace elements,
increasing the amount of trace elements transported from the roots
to the leaves or other parts, regulating the ratio and balance of
macronutrients and trace elements, and enhancing the synthesis and
transportation of sugars, starches, proteins, fats and various
vitamins by enzymes. It can promote the activity of enzymes,
convert polysaccharides into soluble monosaccharides, increase the
synthesis and accumulation of starch, protein and fat substances,
accelerate the transport of various metabolic primary products from
stems, leaves or roots to fruits and seeds, and make the fruits
plump and thick.

Recommended Dosage:
- Agriculture: 5-15 kg per acre (for base application or flush application),
avoiding excessive use that could lead to soil acidification or
nutrient imbalance.
- Aquaculture: 0.1-0.5 g per cubic meter of water, with attention to
sodium/potassium salt forms in freshwater farming.
- Animal Husbandry: 0.1%-0.5% added to feed; excessive amounts may affect palatability
or mineral metabolism.
Compatibility:
- Avoid direct mixing with strong alkaline substances (like lime) or
pesticides containing heavy metals, as this may reduce humic acid
activity.
- Can be used in conjunction with microbial agents and organic
fertilizers for enhanced effects, but should be applied separately
or with an interval.
