Improving Dissolved Oxygen in Irrigation Ponds

Aerators, algaecides, nutrient runoff, oh my! Now you’re stuck with an irrigation pond full of algae and deplete of oxygen… And you thought that letting nature do it’s thing would be easy?

Maintaining good quality water in your irrigation pond shouldn’t have you pulling out your hair (and your wallet).

In this article, learn how diatoms are the secret component of natural, low-maintenance, and oxygen-rich irrigation pond that will keep your lawns (and wallet) lush with greenery. Nature has a way of making your life easier. The times have changed - and so have advancements in irrigation pond management tools.

Challenges of Modern Irrigation Pond Systems

The greatest challenges of a modern irrigation pond is effectively combating a deficiency of dissolved oxygen, as well as an increase in dissolved solids and nutrient runoff from local homes or farms.

Lack of Dissolved Oxygen

Ever find yourself wondering why is it so hard to make nature “do it’s thing” in your golf course water hazards or irrigation ponds for a football field? The cause of the havoc is a deficiency of Dissolved Oxygen (DO) in the water.

Back in the day, the most commonly used sources of irrigation water came from rain and river water. This kind of water was naturally infused with DO, ideal for nurturing the roots systems of lawns or agriculture.

Today, low water resources have forced golf course owners, farmers, and other groundskeepers to use water sources that are low in DO. This causes all kinds of adverse effects for the natural marine ecosystem as well as the plant life that depends on the water supply.

The law of balanced oxygen states that using irrigation water with poor DO will:

  • Draw oxygen away from plant roots
  • Decrease soil microbial activity
  • Foster nematode root damage
  • Impair plant nutrient absorption
  • Decrease plant metabolism

 

Increase in Nutrient Runoff & Dissolved Solids

Another modern peril of irrigation ponds is that they are susceptible to high nutrient runoff and dissolved solids that cause buildup in the irrigation system.

Nutrient runoff happens when the water from the surrounding areas collect into the pond to be used for watering, causing a buildup of algae-feeding nutrients.

This increase in nutrients feeds the population of bad algae. After an algae bloom develops, the biological oxygen demand asphyxiates affected plant and marine life, which makes it hard to maintain a good level of DO in the water.

Additionally, reclaimed water is often added that is full of dissolved solids that causes blockages and increases the need for maintenance or replacement of irrigation equipment over the years.

While there are new problems in the modern world of farm pond maintenance, let's get back to the basics with nurturing the good algae - diatoms.

 

Natural Maintenance for Your Irrigation Pond and Grounds

If you’re familiar with the irrigation pond challenges above, you may already have an aerator installed in your pond to increase the DO levels, as well as a dosing schedule of algaecides and water treatments.

The problem with using an artificial solution to these modern problems is just that - it’s artificial. Not only that, it’s high maintenance and it costs a lot of money.

The good news is that you don’t have to invest for years in a contrived system of pond maintenance. Let’s explain how easy farm pond maintenance is possible with diatoms.

How Diatoms Increase DO & Decrease Nutrient Excess in Irrigation Ponds

Are you familiar with the homeopathic cure that claims that “like cures like.” With diatoms, this is a similar principle to restore natural balance to any body of water. Nano-technological advances have discovered that micro-organisms called diatoms are the “good” algae that produces nutrients that feed a healthy ecosystem instead of depleting it.

Diatoms consume the excess nutrients and dissolved solids from the runoff, while producing nano-bubbles of dissolved oxygen. Nano-bubbles have many advantages over macro-bubbles produced by typical pond aerators, including:

  • Larger interfacial area
  • Higher inner pressure
  • Lower rising velocity in water
  • Longer lifetime to maintain DO levels
  • High mass transfer efficiency

 

Time for a Sustainable Upgrade to Irrigation Ponds

Increasing dissolved oxygen in your irrigation ponds will allow you to remove your aerators, stop feeding algaecides to an already toxic situation, and enjoy your property stress free.

By adding Nualgi Lakes to your irrigation pond, the diatoms begin to starve out the normal algae while they produce DO and good nutrients ideal for irrigation. Get rid of your heavy equipment and your years of irrigation pond induced headaches.
