Potassium Humate its and  Application
potassium Humate

 what is potassium humate?

Potassium humate is a 100% water-soluble powder product. Is has a high concentration and provides organic matter and potassium, so not only improves the soil in a physical, chemical and biological level, but also provides one of the three primary elements that every plant needs. It is recommended for its dilution in the water with which farmers prepare the mix and be used like the traditional liquid humic acids, to be applied to the soil through the fertirrigation system.

When we use potassium humate, we are providing a high percentage of humic acids, and also a small amount of fulvic acids.

Which is the manufacture process?

For the manufacture of potassium humate, we start with mineral leonardite. After the proper treatment of this raw material, we obtain humic extracts of more quality and agronomically profitable.

Leonardite is a humified substance (vegetal material that is been decomposed since antiquity. It has a high content of organic matter and it is in the middle point between the turf and lignite total transformation to carbon. The manufacture process or extraction is complex and it is required the use of the needed raw materials in their right proportion to obtain an optimal extraction, which is done by potassium hydroxide (to get the best final product). The final result is a liquid product that is dried and commercialized in bags of different size.

Which is the difference between applying the solid and liquid formulations?

The humic acid concentration in solid products is higher than in the liquid ones.

Thus, with a small dose of product, it is obtained an important effect on the crop. However, the dose with liquid products should be higher.

As solid products are very concentrated, we only move during transport the material that is going to have a positive effect on soils, avoiding the movement of water. This water would be used later by the farmer in order to have the mixture and dilute the product directly on the field, before its application through the irrigation system. As an alternative, it can be used liquid humic acids, being in this case containers of 1000 l volume or carafes of 20 l the most common packaging; as the dose per hectare to be used is around 40-50 l/ha, divided in several applications.

Although the product can also be applied via foliar or directly to the soil, it is recommended the application after dilution with the irrigation water, because it is on the soil where it will have a big effect. With this technique, the product is dilute in the water that will be used later for the irrigation, profiting the flux of water as a carrier of the product. This modality entail water and energy saving and avoid environment pollution.

Which is its agronomic activity?

It improves the soil at physical, chemical and biological levels, so the structure is improved, as well as the cation exchange capacity and the soil microorganisms. As a consequence, the nutrient assimilation is better, and not only the growth and development of the crop is favoured, but also the quality of crops is improved.

When we apply the product, we are providing one of the biochemicalliest active materials that can be found on soils. Nowadays it we use this kind of product because it has a recognised and growing use because of its beneficial impact on the growth of crops, being specially noticeable in the soils with few organic matter.

The benefits of its use are:

  • Addition of organic matter to deficient soils and increase of soil fertility.
  • Increase of vitality and root development.
  • Increase of the cation exchange capacity and improvement of nutrient absorption.
  • Increase of chlorophyll synthesis.
  • Improvement of seed germination.
  • Stimulation of beneficial microbial activity.
  • Improves the soil structure and the water retention capacity.
  • It naturally chelates the microelements of alkaline soils and increases its availability for plants.

The plant growth is improved through the structural improvement of the soil, not only in clay soils, but also in the sandy ones; it improves the development and the radicular growth. When this product is applied to clay soils, it helps to break the compacted soils and it allows to increase the water penetration and to improve the growth and development area of roots. When it is applied to sandy soils, it adds the essential organic matter, which is needed for water retention. Therefore, roots can grow and the clay soils can keep and avoid the washing of vital nutrients for plants.

The plant growth is also favoured, due to the improvement of the plant hability for absorbing nutrient. It is especially beneficial for the liberation of the nutrients that are retained on the soil, so it makes them available for the plant when it needs them.  

The activity of the beneficial soil microorganisms is crucial for the soil sustainability and for the plant growth. Humic acids stimulate the microbial activity, because they are a carbon source for their alimentation, favouring then their growth and activity. Soil microorganisms are responsible of the nutrient solubilization, like phosphor, making them available for the plant. Besides, microorganisms are responsible too for the continuous formation of hummus in the soil, because they break organic matter that is not completely decomposed.

The use of the product on a regular basis reduces the fertilization needs, because both, soil and plant, are going to do a better use of nutrients. In some cases, fertilization can be completely eliminated if the is enough organic matter, so the soils can be self-sufficient through the microbial processes and the hummus production.

Finally, what is more interesting for farmers is that plants are more healthy, with a stimulated growth and it is obtained a higher productivity, profitability and quality of the harvest.

Would it be suitable to improve the natural fertility of the soil?

This is like the main question, from which the interview stats. And the answer is of course. Even more, it has activity in different levels:

There is no better way to enhance the economics of farming, than to build soil humus and enhance the natural processes, suchas microbial activity, which can be sustained over a long period of life. Potassium humates derived from lignite brown coal arealkaline, rich in carboxylic and phenolic groups, aromatic in nature and provide favourable conditions for biological activity,chemical reactions and physical improvement of soil.

Accumulation level of natural humic acids like potassium humate has shownto reduce the need for commercial fertilizers because it improves fertilizer efficiency. The utilization of humic acid has been foundto reduce the leaching of fertilizers and pesticides into aquifer and surface waters. By using humic acids, growers will graduallyreduce application macro and micronutrients fertilizers application with addition to the improvement of overall crop yields and quality.

What is potassium humate?

Potassium humate is the salt of humic acid, derived from lignite brown coal and rich in carboxylic and phenolicgroups

Humic acid influence the plant growth both directly and indirectly. The indirect effect of humic acid improvesphysical, chemical and biological condition of soil

Its direct effects attributed due to its metabolic activity in plant growth

Potassium humate enhance soil health as well as environment quality during crop cultivation.

Physical Benefits :

  • Improve the soil’s water holding capacity – Humic substances function as water sponges
  • Increase soil aeration and soil workability by improving ‘crumb’ structure in the top soil
  • Encourage soil animals
  • Help maintain a more uniform soil temperature

Chemical Benefits :

  • Act as a natural chelator (by providing a high cationic exchange capacity) to improve the uptake of
  • minerals, nutrients and trace elements by plants
  • Act as a buffer to neutralise alkaline and acidic soils, freeing many previously bound trace elements
  • Stabilise or assist in the degradation of toxic substances (including toxic pesticides

Biological Benefits:

  • Stimulate the growth and proliferation of beneficial soil organisms (algae, yeast, bacteria, nematodes and
  • mycorrhizae)
  • Enhance root initiation and improve root growth
  • Accelerate seed germination
  • Regulate hormone levels in stressed plants

The Function of Potassium Humate

by admin 0 Comments

The function of Potassium Humate, let us start with a humic acid functional group in potassium humate can absorb and store potassium ions, prevent loss with water in sandy soil and leaching soil, and prevent fixation of potassium by sticky soil.

In addition, some parts of potassium humate are low-molecular-weight humic acids such as fulvic acid, which has a corrosive effect on minerals such as potassium silicate and potassium feldspar, which can be slowly decomposed to increase the release of potassium and increase the content of available potassium.

The utilization rate is 87% -95% higher than ordinary potassium fertilizer, which increases fertilizer efficiency, crop yield, and quality.
Potassium humate has a combination of land use and land cultivation; long-term and quick-effect coordination; special effects in water retention and fertilizer retention. It combines the advantages of inorganic fertilizers and farm fertilizers and is superior to them.

The function of potassium humate is a good controlled-release fertilizer so that the nutrients in the early stage will not be too much, the nutrients in the later stage will not be too low, and the fertilizer supply curve is stable. The release rate can also be controlled by physical and chemical biotechnology methods to achieve two-way regulation of accelerated release and sustained release.

The supply of nutrients in the fertilizer is basically synchronized with the nutrient requirements of the crop to achieve dynamic balance.
Ordinary chemical fertilizers (such as urea, 50% -60% potassium fertilizer, diammonium phosphate, etc.) can easily produce soil compaction and pollution to water and air, and potassium humate can be avoided or significantly reduced.

And it significantly increases crop yield, improves crop quality, improves crop nutritional content, reduces nitrate content, and has excellent color, fragrance, taste, and portability. It is the material foundation of environmentally-friendly agricultural cleaner production and green food. Potassium humate has low loss, high utilization rate, stable plant absorption, and two-way improvement in yield and quality.

The function of potassium humate, It is a “green” potassium fertilizer for agricultural applications and a substitute product for potassium chloride and potassium sulfate for general agricultural use. Potassium humate is suitable for any crop.

Potassium Humate and Fulvic Acid Analysis

by admin 0 Comments

Potassium humate and fulvic acid are particularly interesting because they both contain molecular structures of polar and non-polar substituents, so they can transport both water-soluble and water-insoluble species. Indeed, colloidal organics.

For example, soluble humic acid and fulvic acid found in groundwater and surface water are called “third stage” in the traditional two-stage. Solid and water phase systems are used for hydrochemical modeling. Because potassium humate and fulvic acid in the colloid size range are key factors in chemical waste migration and other hydrological processes
A process that can produce enough humus and yellow rot material like fulvic acid.

Sampling methods. Chemical and physical characteristics change with size are necessary for improvement. Our understanding of their role in hydrogeochemistry. Classic method for separating potassium humate and fulvic acid from soil and water. The pH is about 2.

Many studies have attempted to remove metals from humus and treated fulvic acid with hydrochloric acid and hydrogen fluoride. These methods are because strong chemical treatments will change the chemical structure of humus and fulvic acid through acid-catalyzed reactions (decarboxylation, degreasing, etc.) and cause physical changes in shape (hence effective diameter). Other methods to minimize.

Including radionuclides and toxic metals in their natural geochemical state) A method of sampling and sizing of potassium humatefulvic acid, and other humic acids.

Organic and inorganic colloidal materials from groundwater or surface water can be reproduced with minimal artifacts (chemical and physical artifacts). The method should be suitable for processing a large amount of water to obtain sufficient materials for multiple analytical procedures (infrared, C-NMR, pyrolysis, chromatography, mass spectrometry, etc.) Methods should also be relatively simple and easy to use, and easy to use in the laboratory, especially in outside
