Use of humic acid

Humic acids also increase crop growth by increasing plant growth promoting hormones such as auxin and cytokinin, which aid in stress resistance, nutrients metabolism, and photosynthesis (Billingham, 2012; Rose et al., 2014; Canellas et al., 2020; Laskosky et al., 2020; Nardi et al., 2021; van Tol de Castro et al., 2021

What are the benefits of humic acids?

Humic acid neutralizes acidic and alkaline soils; regulates pH-value of soils, increasing their buffering abilities; and has extremely high cation-exchange properties. Benefits: Improves and optimizes uptake of nutrients and water holding capacity. Stimulates plant growth with its rich organic and mineral substances.

Is humic acid a fertilizer?

Humic acids generally aren't considered a fertilizer. Whereas fertilizers provide specific nutrients to plants, humic (and fulvic) acids increase the availability and uptake of those nutrients, and improve the overall growing environment.

When should I give my plant humic acid?

The best time to amend the soil with humic acid is spring or fall season when the plants are growing. Humic acid is best applied when preparing the soil for gardening or in potted plants. You should also use humic acid as a soil amendment when transplanting seedlings.

Can you give a plant too much humic acid?

People will also ask if it's possible to apply too much humic acid to the lawn and the answer is no. You won't harm the lawn with too much humic acid but for sure, you will waste it. In other words, throwing down more than the labeled rate will not hurt anything, but it certainly is wasteful and expensive.

How long does humic acid last in soil?

Humic substances, on the other hand, are stable, long-lasting biomolecules. Components of humus have a mean residence time (based on radiocarbon dating, using extracts from non-disturbed soils) of 1,140 to 1,235 years, depending on the molecular weight of the humic acid.

Does humic acid change soil pH?

The addition of humic acid will exchange H + cations to cause lower soil pH. The soil cation exchange has a capability to greatly influence the content of clay and organic matter. The higher the content of clay and organic matter, the smaller the pH change, as in the case on soil 2.

How often can you use humic acid?

Apply solution around root zone of existing plants: Water in just enough to soak the root zone (up to 4 inches for most.) Apply as often as every two weeks.

Which is better humic acid or fulvic acid?

Fulvic acids are more active than humic acids due to its oxygen content that is almost double the amount of humic acid. Fulvic acid is the most effective organic chelating compound and can be used through foliar application due its small molecular size and electrical charge which plant can immediately uptake.

How do you apply humic acid to plants?

You mix the humic acid with water and apply it directly to the leaves of your plants using a pump sprayer. This method is ideal for treating specific problems like nutrient deficiencies or pest infestations.

Do plants absorb humic acid?

More about Humic Acids The exact composition of humic molecules varies by source. They're not soluble in water in acid conditions, but are soluble in alkaline solutions. Humic acids work best in the soil, where they readily unlock nutrients and bind to them, making them available for uptake into plants.

Does humic acid help root growth?

Application of humic acid improves seed germination and seedling growth, stimulating root initiation and root growth. The humic acid doesn't contain rooting hormones; instead, it helps prevent the oxidation and breakdown of rooting hormones, allowing IAA to remain active longer.

Can I mix fertilizer with humic acid?

Combining humic acid with phosphate fertilizer affects humic acid structure and its stimulating efficacy on the growth and nutrient uptake of maize seedlings.

Does humic acid aerate soil?

Applying humic acid to clay soils can help loosen them, allowing for better water and air penetration. In turn, plant roots are better able to develop and take up nutrients.

Is humic acid necessary?

Increased Nutrient Uptake Without humic acids present, some of the nutrients provided by fertilizers become inaccessible to plants, so money is lost and plant health suffers. Thus, humic acids are vital for both the health of plants and for growers' economic well-being.

What does humic acid do to pH?

Similar to lime, humic acids have a positive effect on the soil and the arable crop. For one thing, they neutralize the pH value in acidic soil - this increases the buffer capacity of the soil, which means that acidic precipitation has less of a negative effect on soil reactions.

Do tomatoes like humic acid?

Humic Acid Enhances the Growth of Tomato Promoted by Endophytic Bacterial Strains Through the Activation of Hormone-, Growth-, and Transcription-Related Processes. Plant growth-promoting bacteria (PGPB) are promising alternatives in the reduction of the use of chemical fertilizers.

Does humic acid have NPK?

HUMAGRA® NPK 10-0-3 + HUMIC ACIDS is a liquid, organic-mineral fertilizer based on potassium humate and plant-available nitrogen. It provides the crop with plant available nitrogen and potassium for high crop yields.

What does humic acid do to clay soil?

In addition to improving soil structure, humic acid adds stable carbon to soils, improving water drainage and retention. It aerates dense clay soils, and adds organic material to help with water absorption to sandy soils.
