How Fulvic and Humic Acids Benefit North Texas Trees

Date September 30, 2019

Millions of years ago, the soil in Dallas, Ft Worth, and Highland Village was healthy. And tree life in North Texas grew robust root systems, healthy bark and wide, green canopies.

The advent of synthetic nitrogen fertilizers after World War II has depleted Denton, Double Oak, and Flower Mound soils, and trees couldn’t absorb these precious nutrients that were once available millions of years ago.

Our modern lifestyle has contributed to this depletion, including urban density, the overuse of synthetic fertilizers, and climate change. In the modern age, North Texas trees lack the nutrients to enable them to resist disease, drought stress, and insect infestations.

What is Humic Acid?

Scientists have uncovered humic acid and its cousin, fulvic acid. Researchers don’t know all of humic acid’s potential to improve plant life, but they realize that introducing it to plants, including trees, makes the plants hardier.

Ever since the end of World War II, homeowners and commercial property managers have used synthetic fertilizers to feed their lawns, landscapes, and trees. These same fertilizers have depleted the soil so that essential nutrients can’t be absorbed by plant life.

Humic acid, along with fulvic acid, are natural plant-growth stimulators helping plants, such as North Texas trees, absorb more nutrients to develop deep, strong roots, bark, and canopies.

These nutrients improve your tree’s metabolism, nutrient uptake, and tree development. When your Argyle or Bartonville trees receive humic or fulvic acid in their fertilizer, these trees are better able to withstand drought and compaction as well as ward off diseases and insects.

Here are humic acid’s other benefits:

  • It holds onto calcium and other micronutrients in the tree’s cells.
  • Humic acid, with the help of soil microorganisms, develop robust root systems, including root hairs that grow deep underground for moisture and nutrients.
  • It improves your Westlake trees’ ability to absorb nutrients faster.

What are Fulvic and Humic Acids?

Fulvic acid is gold in color, whereas humic acid is dark brown or black. TreeNewal Certified Arborists use fulvic and humic acids to help with nutrient absorption as well as improved tree health.

Fulvic and humic acids developed over millions of years with fungi and microorganisms breaking down soil and rocks. Scientists extract fulvic and humic acids from peat moss, lignite, Leonardite, and humic shales.

You can find humates (scientists extract humic acid from humates) in bogs, marshes, and dry lakebeds. Fulvic acid comes from Leonardite that has the highest percentage of fulvic content.

When you mix fulvic and humic acids into your Double Oak soil or fertilizer, you’ll find your plants—including trees—start developing robust leaves, blossoms and fruit.

Here are Fulvic Acid Benefits

  • It helps tree cells become more permeable to take in nutrients.
  • It helps tree cells grow and develop rapidly.
  • It increases photosynthesis, a tree’s way of turning chlorophyll and nutrients into food sources.
  • It improves the tree’s ability to absorb trace elements and stimulate beneficial enzymes.
  • It chelates or bonds macro- and micronutrients to your tree’s cells.
  • Fulvic acid has a low molecular weight enabling it to enter into your tree’s cell walls and taking more abundant nutrients with it. Without fulvic acid, your trees couldn’t absorb and take those nutrients inside the plant’s cell walls.
  • It maximizes synthetic or organic fertilizer’s nutrient efficacy.
  • Your Westlake trees will produce more food because fulvic acid increases your tree’s metabolism, which in turn increases enzyme activity.
  • You’ll need less fertilizer in the future to maintain the health of your Aubrey trees.
