Top benefits of humic acid powder fertilizer for plants

What's humic acid ？

Humic acid for plants is a mixture of natural organic macromolecular compounds, which exists in all soils, plants and animals,and have been widely used in agricultural production in recent years due to their unique physiological functions.








Mechanism of humic acid action

Humic acids range in molecular size from 10,000 to 100,000,and combine mixtures of carbon chains and carbon rings. (In addition to carbon, they also contain oxygen, nitrogen, hydrogen, and phosphorus.)
Humic acids work best in the soil, where they readily unlock nutrients and bind to them, making them available for uptake into plants. And they chelate toxic metals, preventing harmful material from entering the plant.
Also,when foliar applications, humic acid increase the cell wall permeability of plants, which in turn increases the uptake of nutrients.

Benefits of using Humic acid for plants

  1. Improved soil structure, prevents high water and nutrient losses in bad soils.
  2. Regulates the pH-value of soils.
  3. Enhances plant’s nature resistance against diseases and pests.
  4. Stimulates root growth, and improves the plant’s uptake of nutrients and water.

What’s more, In addition to these above benefits, its role in plant stress resistance has also received increasing attention.

  • Plant drought stress

Under drought conditions, the application of humic acid-containing fertilizer can promote the increase of proline content in plant leaves to improve the drought resistance of crops.

  • Plant salt and alkali stress

Humic acid can enhance the salt resistance by regulating the change of fructose concentration and alleviating the damage of material membrane under salt stress.

  • Plant temperature stress

Under low temperature stress, humic acid can increase crops’s proline and abscisic acid content, reduce the spead of transpiration rate, stomatal conductance and net photosynthetic rate of plants.

Under high temperature stress, It enhances the heat resistance of crops by increasing the activities of crop superoxide dismutase and peroxidase.





  • Plant disease resistance

Humic acid can promote growth by increasing the sugar content and chlorophyll content of leaves, which indirectly improves the disease resistance of crops.



In fact,crops are constantly undergoing the test of the natural environment、pests and diseases, the use of humic acid will greatly benefit their growth.


Humic acid’s usage and precautions

For flushing, drip irrigation or foliar application,

It is recommended to use potassium humate, ammonium humate or potassium fulvic acid, ammonium fulvic acid.

Mixed with base fertilizer

It is recommended to choose ammonium humate or ammonium nitro-humate.

Notice

The humic acid powder can be applied dry, but it is more commonly mixed with water in a watering can, sprayer, or irrigation system.

Best Guide of Common Plant Disease in Garden

图片
For home gardeners, nothing is more frustrating than seeing their work destroyed by pests and diseases. The disease occurs when environmental conditions are suitable for the growth of pathogens on susceptible hosts. Some pathogens attack a variety of plants, while others attack only specific plants. In addition, some pathogens can attack all parts of the plant, while others attack only selected tissues. Many types of organisms cause plant infections , but the top five types of plant pathogens are fungi, water molds, bacteria, viruses, and nematodes. Adverse environmental conditions may also lead to non-infectious diseases of plants, called diseases. Adverse conditions include inappropriate soil pH, nutrient deficiency and toxicity, soil compaction, excessive water content, and herbicide destruction. Plants weakened by adverse conditions may be more vulnerable to pathogens. The following is a brief introduction of several common plant diseases, symptoms and solutions, I hop...

Best Guide- Details to Trimming Cannabis

Trimming is among the most reliable means to adjust and guide the growth of a cannabis plant. If you're seeking to limit the dimension of your plant, promote side branching, delay the onset of flowering, or increase yield, trimming checks all packages. It may feel counterproductive to trim parts of your plant as it expands. However, by pruning ineffective development, you can reroute the plant's energy as well as sources into establishing high-quality flowers. While trimming is sensibly straightforward, it's likewise an ability that comes to be polished and less complicated with the method. These pruning pointers and also tricks should assist in demystifying the procedure. Why do you trim marijuana? Pruning refers to the process whereby tiny, certain sections of the plant are cut to motivate healthy growth. At its most basic level, trimming eliminates development that is harmed, ineffective, or blocking sunshine from reaching budding flowers. Pruning describes the procedure...
