The Aerobic Difference

For both Soil and Water Systems!

For years, turf managers and growers have utilized both chemical and mechanical means to incorporate oxygen into their soils. Many realize that the type biological activity found in their soils is vital to maintaining healthy growth and quality turf grass. Soil scientists agree that this is true. Disease factors found in both plants and water primarily stem from the lack of oxygen. Soils lacking adequate oxygen are known as anaerobic while soils that have adequate oxygen on a consistent basis are referred to as aerobic. Therefore, turf managers often mechanically aerate their soils, using heavy equipment that literally pokes holes into the soil allowing air to penetrate, but this practice is costly and damages the turf.

Delivering oxygen to the root zone is necessary as conditions such as black layer often plague even the best of golf greens and cause putrid odors that resembles rotten eggs. This odor is caused by the over growth or proliferation of anaerobic bacteria such as desulfovibrio and desulfotomatuculum bacteria and/or various blue-green algae or cyanobacteria which produce mucilage that blocks both air and water movement in sandy and clay soils and acts as an energy source for anaerobic bacteria. It is the by-products of these various bacteria and the subsequent toxic soil conditions that occur that have a negative impact on the growth of roots and these have also been found to harbor disease-causing bacteria.

New Study Uncovers Key Role of Bacteria in the Formation of ‘Red Tide’ Algal Blooms

A study confirms the symbiotic relationship between Algae and Aerobic Bacteria.

The researchers found that certain species of bacteria form a mutually-beneficial relationship with the algae that promotes the growth of each. The bacteria release a chemical which helps the algae absorb iron, a critical nutrient for photosynthesis. The algae, in turn, release organic compounds to support the growth of the bacteria.

The study also offers new insight for climate change models, since dimethylsulfide, a gas produced by the bloom-forming algae, plays a critical role in the process of cloud formation and the ability of clouds to reflect sunlight back into space. The degree to which light is reflected in turn influences solar heating of the Earth, affecting global climate.

Nualgi - video of a lake in Hyderabad

The video of the impact of the use of Nualgi on a lake in Hyderabad is available on You Tube.

This clearly shows the oxygen bubbling up, due to the bloom of Diatom Algae.

The Blue Green Algae crashed out in a couple of hours.
The lake is visibly dirtier after 2 hours, this is part of the cleaning up process.

The organic matter that had settled down on the lake bed over many years, becomes loose and floats up.

Thus the lake is fully cleaned up from the bed upwards.

The oxygen bubbling is visible for over 2 weeks.

This would be visible only in heavily polluted lakes and not in lightly polluted lakes, since the Diatom bloom would be more when more nutrients are available in the water.

The dissolved oxygen level raises steadily over a few days.

The Diatoms are consumed by Zooplankton and these by fish, so there is no residue.
