Fulvic and Humic Acids: Importance and Use in Plant Nutrition

Fulvic and humic acids are among the natural substances that significantly improve plants’ ability to absorb nutrients efficiently from fertilisers, thereby supporting their growth and overall vitality.

To make it easier to explain how these beneficial substances help with the cultivation of all kinds of plants, and how they can become the key to exceptionally high yields from your flowers or crops, let us begin with the most important terms from our glossary. Simply click on the term in question:

• Humus and humification
• Humates
  • Fulvic acids, fulvic acids (FA)
  • Humic acids (HA)
  • Humins
• Chelates, chelation, chelators
• Leonardite

Humates and plant nutrition

Humate-based additives can be applied without concern both in home gardening, or indoor, and outdoors in outdoor environments. Their use is not limited by the choice of growing method or substrate either. As supplements (additives) to basic fertilisers, thanks to their excellent solubility they significantly support the development of useful and ornamental plants, flowers or crops, including medicinal herbs!

Soluble humates contain literally a wealth of natural substances that strongly support plant growth, which is the result of the first of the two most important benefits associated with the application of humic substances in plant nutrition:

• Better uptake and use of nutrients by the plant
• Stronger plant immunity

The other benefits will be covered shortly with the individual substances and products. Whether you have already clicked through the above terms, which are usually known mainly by environmentally focused growers, or not, let us summarise for each individual humic substance why it is worth using its strength in irrigation, and which specific products are a guaranteed source of it.

High-quality fulvic acid is considered by many growers to be the very best boost you can give your plants in addition to basic nutrition. If only because it is a natural chelate. What does that mean? Ultimately, it means that your plants will have a more productive root system and more important nutrients available. Fulvic acids form specific chemical bonds with certain micronutrients, preventing interaction with other ions, and all nutrients bound to the chelate can then successfully travel from the roots to the plant tissues. The result of chelation is much higher bioavailability of nutrients that would otherwise not dissolve. The importance of fulvic acids can also be summed up by saying that they help plants fully use their potential. And without having to reach for mineral supplements, you will get closer to achieving the harvest of your dreams.

That is why we recommend the top-quality additive with a high fulvic acid content and balanced pH: Previous article Next article
