Plant growth regulator HUMEKS

THE APPLICATION OF THE PLANT GROWTH STIMULANT HUMEKS BASED ON MODIFIED HUMIC ACIDS HAS SEVERAL ADVANTAGES IN AGRICULTURE:

1. Increased yield: activates the absorption of nutrients such as nitrogen, phosphorus and potassium by the roots, thus increasing the yield of cultivated plants.
2. Stimulation of plant growth and development: promotes the activation of physiological processes in plants, which leads to an increase in green mass, development of the root system and strengthening of plant health.
3. Enhanced resistance to stress: helps plants to better tolerate stressful conditions such as drought, diseases and soil pollution.
4. Improved crop quality: the application of humic acids improves the quality of fruits and vegetables, makes them juicier and tastier, and also allows them to be stored for a long time.
5. Environmental safety: humates are natural compounds, so they do not harm the environment and do not remain in the soil.
6. Saving time and money: using the HUMEKS growth stimulant reduces the amount of fertilizers and plant protection products needed, which will help save farmers time and money.

MODIFIED HUMIC ACIDS

The product contains modified humic acids. They belong to about a hundred of our own unique variants of this active substance, developed as a result of numerous scientific experiments.

During the research our scientific specialists identified the presence of a dose-effect for the quantitative interval of the content of humic substances that are part of the products of the agrochemical industry. In other words, the effectiveness of the active substance directly depends on the quantitative indicators of the components. The slightest deviation from the specified norm can cause undesirable results.

Scientific and field studies allowed us to identify the optimal dose-effect curve. Such a curve demonstrates a change in the effect of modified humic acids on the plant depending on their concentration. Therefore, one of the concepts underlying the development of the HUMEKS stimulant composition was the results of these studies.

CRITERIA THAT THE COMPANY’S SCIENTISTS USED DURING THE MODIFICATION OF HUMIC ACIDS:

The maximum level of penetration of modified humic acids is a guarantee of maximum effectiveness of the formulation.

At the same time, studies were conducted to achieve the maximum degree of penetration of modified humic acids into plant cells and their main organelles (nucleus, mitochondria, chloroplasts).

According to studies, this indicator is influenced by the molecular weight and biological characteristics of plants. For this purpose, we conducted short-term microvegetation experiments. During a set of experiment options, we found out the maximum saturation of plant cells with modified humic acids depending on different molecular weights.

THE LEVEL OF SATURATION WITH MODIFIED HUMIC ACIDS OF PLANT CELL ORGANELLES DEPENDING ON THE MOLECULAR WEIGHT

The data presented allow us to draw the following conclusion: modified humic acids, which are part of the HUMEKS growth stimulant, retain their activity and water-soluble qualities in environments with different pH levels, they effectively saturate plant cells, which allows to fully reveal the inherent potential of crops.

Humic acids must remain active and water-soluble in acidic and alkaline environments. The main properties of humic substances: effective activity, solubility and stability in solution depend on the pH of the environment. The reason for this is their structural and group composition.

Despite the fact that humic substances are stably soluble in a neutral environment, a decrease in pH has an effect on this property, which is more specifically determined by the chemical composition and origin of the substances in the product. The consequences of changing this property can be extremely undesirable: from the loss of efficiency of the tank mixture to the failure of spraying equipment, because insoluble particles of humates in the sediment can clog nozzles and other components of the units.

DEPENDENCE OF THE MASS FRACTION OF HUMIN SUBSTANCES IN SEDIMENT, % ON THE pH OF THE ENVIRONMENT

The first step in solving this problem was the selection of humic acids and the study of their behavior in solutions in order to achieve their stability in tank mixtures.

This problem arose due to the producer application of low-quality fertilizers, the prices of which are relatively low. However, such products have one undesirable feature – acidification of the working solution. Given that the pH of water does not correspond to neutral values ​​in many regions of our country, we have the following: in alkaline environment, phenolic and carboxyl groups deprotonate, and this leads to the repulsion of negatively charged groups, so the molecules of humic substances have an elongated configuration.

With a decrease in pH, the functional groups protonate, the repulsion effects are minimized, and finally the molecules acquire a helical conformation. At this stage, the hydrophobic areas are in the inner part of the structure, and the hydrophilic parts are in contact with the aqueous environment, that is, we have a micelle-like organization and a decrease in the surface tension of humic substances.

Behavior of humic substance molecules in alkaline medium and aggregation process due to the decrease in pH of medium:

(a) repulsion of deprotonated groups if pH>7; (b) intramolecular and (c) intermolecular aggregation in case of decrease in pH of medium; (d) precipitation of humic substances if pH=4.5.

Due to increase in hydrogen ion concentrations, protonation of carboxyl groups of humic substances occurs, which leads to precipitation of macromolecules. This process begins when pH exceeds 5.5. This continuous process promotes aggregation of humic substances at the molecular level and leads to formation of hydrophobic surface. To sum up, acidic medium deactivates humic acid molecules.

Creation of the plant growth stimulant HUMEKS with modified humic acids, which will retain water-soluble properties and activity in acidic medium, became the answer to this problem.
