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.

Directions For Use

Soil Improvement

The application rate per hectare is 30 to 75 kilograms. Apply it two to three weeks before planting in spring, evenly spread potassium humate powder on the soil surface, 

and then conduct plowing to fully mix it with the soil.

Base Fertilizer

Evenly spread the well-mixed fertilizer in the planting furrow or planting hole. The general dosage per hectare is usually 45 to 90 kilograms. 

Potassium humate powder can be used as base fertilizer together with organic fertilizer, compound fertilizer, etc. When using it, 

first mix potassium humate powder and other fertilizers evenly according to a certain proportion.

Top Dressing Fertilizer 

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. Positive impacts on soil

Excellent soil improvement effect

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.

Promote soil microbial activities

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. Helping effects on plant growth

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. Advantages in fertilizer synergy

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 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.

What are the differences in the improvement effects of potassium humate on different types of soil?

[Viscous soil]

[Structure improvement]: Viscous soil has fine particles, heavy texture, and poor air permeability and water permeability. Potassium humate can make soil particles agglomerate 

and form a good granular structure. Its organic colloid component can bond soil particles. In viscous soil, it is like a "bridge", connecting small soil particles, increasing soil pores, 

and improving the air permeability and water permeability of the soil. For example, in an environment mainly composed of viscous soil such as paddy fields, 

after applying potassium humate, the compaction of the soil is relieved, which is beneficial to the aerobic respiration of rice roots.

[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 activity 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.

[Soil structure stabilization]: Although sandy soil itself has good air permeability, the structure is loose. Potassium humate can bond sand particles and make the soil structure more stable. 

This helps prevent soil from being eroded by wind or water flow and maintain the integrity of the soil. For example, in some riverbank sandy land or coastal sandy land, 

potassium humate can help fix the soil and reduce soil erosion.

[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.

[Acidic soil]

[pH adjustment]: The pH value of acidic soil is relatively low, which inhibits the growth of many plants. Potassium humate contains alkaline groups and can neutralize soil acidity 

and increase soil pH value. For example, in the southern red soil area where the soil is strongly acidic, the application of potassium humate can adjust the soil pH value to 

a range more suitable for plant growth and reduce the toxicity of harmful elements such as aluminum and manganese to plants.

[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.

[Soil fertility improvement]: Similar to acidic soil, potassium humate can also improve soil structure, increase soil fertilizer retention capacity, and promote the effective utilization 

of nutrients in alkaline soil. It can activate nutrients such as phosphorus in the soil and increase the activity of soil microorganisms, thereby improving soil fertility.
