POTASH HUMATE

Potassium humate is an organic potassium fertilizer and the potassium salt of humic acid. The main components are humic acid and potassium ions. Humic acid is a complex natural organic macromolecular compound. It is a high molecular organic acid composed of aromatic groups and various functional groups. Its molecular structure contains acidic functional groups such as carboxyl group (-COOH) and phenolic hydroxyl group (-OH). These functional groups can combine with potassium ions (K⁺) to form potassium humate. The chemical structure of potassium humate endows it with many unique properties. It has colloidal properties. Its aqueous solution can form a colloidal solution. This colloidal solution can adsorb harmful substances such as heavy metal ions in the soil and play a certain role in purifying the soil. At the same time, the colloidal property of potassium humate also helps to improve the aggregate structure of the soil, so that soil particles can bond together better and form a good soil structure. In addition, it also has ion exchange capacity and can exchange with other ions in the soil, thereby activating nutrients in the soil and improving soil fertility.

Mode d'emploi

Amélioration des sols

Le taux d'application par hectare est de 30 à 75 kilogrammes. L'application se fait deux à trois semaines avant la plantation au printemps, en étalant uniformément la poudre d'humate de potassium sur la surface du sol, puis en labourant pour la mélanger complètement au sol.

Engrais de base

Répartir uniformément l'engrais bien mélangé dans le sillon ou le trou de plantation. Le dosage général par hectare est généralement de 45 à 90 kilogrammes. L'humate de potassium en poudre peut être utilisé comme engrais de base avec des engrais organiques, des engrais composés, etc. Lors de l'utilisation, il faut d'abord mélanger l'humate de potassium en poudre et les autres engrais de manière homogène selon une certaine proportion.

Engrais de couverture

• Root topdressing: During the growth period of crops, potassium humate powder can be used for root topdressing. For vegetable crops, during the vigorous growth period, potassium humate powder can be dissolved in water to make a 0.5%-1% solution, and then poured around the roots of crops. For example, pouring 0.5-1 liter of solution per vegetable plant can promote the growth of vegetable roots and nutrient absorption.
• Foliar topdressing: It can also be used for foliar topdressing. Prepare potassium humate powder into a 0.1%-0.3% foliar fertilizer solution, and choose to spray on the leaves on a windless cloudy day or in the evening on a sunny day. The spraying amount should be such that the leaf surface is moist but not dripping. For example, for fruit trees, foliar spraying during the fruit expansion period can promote fruit development and improve fruit quality.

Potassium humate has many significant advantages in the agricultural field:

1. Impacts positifs sur les sols

Excellent effet d'amélioration du sol

Potassium humate can effectively improve soil structure. It is a good soil aggregate former that can bind soil particles into stable aggregates. This structure is crucial for improving soil aeration and permeability. For example, in farmland where soil compaction is caused by long-term use of chemical fertilizers, applying potassium humate can make the soil become loose and porous again. It is like giving the soil a “loosening massage”, allowing air and water in the soil to move freely and creating a good growth environment for plant roots. At the same time, it can adjust soil pH. In acidic soil, the alkaline groups in potassium humate can neutralize acidity and increase soil pH value. In alkaline soil, it can play a buffering role and prevent excessive soil pH from harming plants. This is like a “pH balancer” for the soil, automatically adjusting the soil pH to make the soil environment more suitable for the growth of most crops. Potassium humate can also increase the cation exchange capacity (CEC) of soil. Soil cation exchange capacity is an important indicator for measuring soil fertility retention capacity. It can adsorb and exchange cations in the soil, such as potassium, calcium, magnesium and other nutrient elements, and preserve these nutrients to prevent them from being lost due to rain leaching. This is like a “nutrient storage bank”, and when plants need these nutrients, they can be released for plant absorption.

Favoriser les activités microbiennes du sol

It provides an ideal living environment and rich nutritional source for soil microorganisms. Soil microorganisms play a key role in the process of decomposing organic matter and releasing nutrients. Potassium humate is like a “feast for microorganisms”. The organic components in it can be decomposed and utilized by microorganisms such as bacteria and fungi. For example, some nitrogen-fixing bacteria can better play the role of nitrogen fixation in the good environment provided by potassium humate and convert nitrogen in the air into ammonium nitrogen available to plants, thereby increasing soil fertility.

2. Effets d'aide sur la croissance des plantes

Enhance plant stress resistance Potassium humate can improve the drought resistance of plants. It can promote the development of plant roots to be stronger and increase the absorption area and depth of roots. In this way, during drought periods, plant roots can better absorb water from deep in the soil. Moreover,it can also regulate the osmotic pressure of plant cells, so that plant cells can maintain a certain turgor pressure under water shortage conditions and reduce water loss. For example, for wheat planted in arid areas, after applying potassium humate, the withering speed of its leaves under drought conditions is significantly slowed down, and the plants can survive better. It also helps to enhance the cold resistance of plants. In a low-temperature environment, potassium humate can increase the content of substances such as soluble sugar and proline in plant cells. These substances can lower the freezing point of plant cells. It is like adding “antifreeze” to the cells to prevent cells from being damaged by freezing. For example, for vegetables planted in northern winter, using potassium humate can reduce the impact of frost damage. In addition, potassium humate can also enhance the resistance of plants to pests and diseases. It can induce plants to produce a series of defense responses and activate the defense enzyme system in plants, such as peroxidase, polyphenol oxidase, etc. These enzymes can help plants resist the invasion of pathogenic bacteria and pests. For example, when plants are threatened by fungal diseases, plants applied with potassium humate can reduce the occurrence area and severity of diseases through their enhanced defense mechanisms.

Promote plant growth and development As a source of potassium fertilizer, potassium humate can provide sufficient potassium elements for plants. Potassium elements play various important roles in the physiological process of plants. In photosynthesis, it participates in the processes of photosynthetic electron transfer and photosynthetic phosphorylation, promotes the assimilation of carbon dioxide, and improves photosynthetic efficiency. At the same time, potassium can also promote the transportation and accumulation of sugar in plants, which is beneficial to the development and quality improvement of fruits. For example, when planting apples, applying potassium humate can make apple fruits fuller, with brighter colors and better taste. The humic acid component in potassium humate can also stimulate the synthesis and secretion of plant growth hormones. These growth hormones can promote the growth and elongation of plant roots and make the roots more developed. Developed roots can better absorb water and nutrients in the soil, and then promote the growth of the above-ground part, such as increasing the height of plants, the thickness of stems and the number of leaves, etc., and finally increase crop yield.

3. Avantages de la synergie des engrais

Improve fertilizer utilization rate Potassium humate can be used in combination with various fertilizers to play a synergistic role. It can adsorb ammonium nitrogen and fix it in the soil to reduce the loss of ammonia volatilization. For example, when using nitrogen fertilizers such as urea, applying them together with potassium humate can increase the utilization rate of nitrogen fertilizers. At the same time, it can also form complexes with phosphorus fertilizers and release the fixed phosphorus in the soil to improve the effectiveness of phosphorus fertilizers. This is like a “little helper for fertilizers,” making fertilizers work better, reducing fertilizer waste, and lowering agricultural production costs.

Quelles sont les différences dans les effets d'amélioration de l'humate de potassium sur différents types de sol ?

[Sol visqueux] [Amélioration de la structure] : Le sol visqueux se caractérise par des particules fines, une texture lourde et une mauvaise perméabilité à l'air et à l'eau. L'humate de potassium peut agglomérer les particules du sol et former une bonne structure granulaire. Son composant colloïde organique peut lier les particules du sol. Dans un sol visqueux, il est comme un “pont”, reliant les petites particules du sol, augmentant les pores du sol et améliorant la perméabilité à l'air et à l'eau du sol. Par exemple, dans un environnement principalement composé de sol visqueux tel que les rizières, l'application d'humate de potassium soulage le compactage du sol, ce qui est bénéfique pour la respiration aérobie des racines de riz.

[Nutrient activation and exchange]: In viscous soil, the cation exchange capacity is relatively high, but the availability of nutrients may be low. Potassium humate can adsorb on the surface of soil colloids and exchange the adsorbed nutrient ions through ion exchange to improve the availability of nutrients. For example, it can exchange potassium ions, ammonium ions, etc. adsorbed by soil colloids for plant absorption and utilization, reducing nutrient fixation.

[Microbial environment optimization]: The improved soil structure and nutrient status provide a better living space for microorganisms. Microorganisms can reproduce and be active better in a soil environment with good air permeability and decompose organic matter to further improve soil fertility. For example, the application of potassium humate can increase the number of beneficial microorganisms, such as nitrogen-fixing bacteria and phosphorus-solubilizing bacteria, in the soil. These microorganisms can provide nitrogen and available phosphorus for plants.

Sandy soil

[Enhanced water and fertilizer retention]: Sandy soil has large particles and large pores and poor water and fertilizer retention capacity. Potassium humate can fill soil pores and increase the water retention capacity of the soil. It is like a sponge, absorbing and retaining water during rainfall or irrigation to prevent excessive downward seepage and loss of water. At the same time, it can also adsorb and retain nutrient ions such as ammonium nitrogen, nitrate nitrogen, and potassium ions, reducing the leaching loss of fertilizers. For example, for some windbreak and sand fixation plants planted on the edge of the desert, after applying potassium humate, the water and fertilizer retention performance of the soil is improved, and the growth environment of plants is improved.

[Stabilisation de la structure du sol] : Bien que le sol sablonneux ait une bonne perméabilité à l'air, sa structure est lâche. L'humate de potassium peut lier les particules de sable et rendre la structure du sol plus stable. Cela permet d'éviter l'érosion du sol par le vent ou l'écoulement de l'eau et de maintenir l'intégrité du sol. Par exemple, dans certaines terres sablonneuses riveraines ou côtières, l'humate de potassium peut aider à fixer le sol et à en réduire l'érosion.

[Promote plant growth]: Stable soil structure and good water and fertilizer retention performance provide favorable conditions for plant growth. Plant roots can take root in the soil better and absorb water and nutrients. Potassium humate can also stimulate the growth of plant roots and make the roots more developed, further enhancing the adaptability of plants to sandy soil environments.

[Sol acide] [Ajustement du pH] : Le pH d'un sol acide est relativement bas, ce qui inhibe la croissance de nombreuses plantes. L'humate de potassium contient des groupes alcalins et peut neutraliser l'acidité du sol et augmenter la valeur du pH. Par exemple, dans la région des terres rouges du sud où le sol est fortement acide, l'application d'humate de potassium peut ajuster la valeur du pH du sol dans une fourchette plus propice à la croissance des plantes et réduire la toxicité d'éléments nocifs tels que l'aluminium et le manganèse pour les plantes.

[Improvement of nutrient availability]: In acidic soil, the availability of nutrients such as phosphorus and potassium is often low. Potassium humate can release the fixed phosphorus by complexing with elements such as iron and aluminum in the soil. At the same time, it can also provide potassium elements and improve the availability of nutrients in the soil. This helps plants absorb nutrients better and promotes plant growth.

[Soil ecological restoration]: Adjusting pH and improving nutrient status is beneficial to the survival of microorganisms and animals in the soil. The activities of some microorganisms in acidic soil are inhibited. The use of potassium humate can restore and enhance the activity of soil microorganisms and promote the balance of the soil ecosystem. For example, soil animals such as earthworms will be more active in the improved acidic soil, and their activities will further improve the soil structure.

[Alkaline soil] [Buffer function]: The pH value of alkaline soil is relatively high. Potassium humate can play a buffering role and prevent excessive soil pH from causing harm to plants. It can react with alkaline substances in the soil, reduce soil alkalinity, and keep the soil pH value within a relatively stable range, creating a suitable pH environment for plant growth.

[Salt regulation]: Some alkaline soils have relatively high salt content. Potassium humate can adsorb salt ions in the soil and reduce the harm of salt to plants. For example, in saline-alkali land, potassium humate can reduce the content of harmful salt such as sodium ions in the soil, reduce soil salt damage, and enable plants to grow better.

[Amélioration de la fertilité des sols] : Comme pour les sols acides, l'humate de potassium peut également améliorer la structure du sol, augmenter la capacité de rétention des engrais et favoriser l'utilisation efficace des éléments nutritifs dans les sols alcalins. Il peut activer les nutriments tels que le phosphore dans le sol et augmenter l'activité des micro-organismes du sol, améliorant ainsi la fertilité du sol.
