Proper farm pond aeration is important to a healthy pond for many reasons. The primary reason is that farm pond aeration maintains dissolved oxygen levels. Without aeration, oxygen levels are difficult to maintain because the algae and water plants found in ponds die and decay.
This creates a layer of organic matter at the bottom of the pond. As this matter decomposes, it consumes the dissolved oxygen in the pond. This oxygen is replaced in the summer by the atmosphere, but this cannot happen in the winter when the pond is covered by a layer of ice.
Once all of the dissolved oxygen is used up, anaerobic decomposition begins. This form of decay without oxygen causes the pond water to become black and stinky.
Preventing Algae Growth
When dead plants undergo anaerobic decomposition, the water becomes acidic. This causes more minerals and nutrients to dissolve in the water, which results in more plant and algae growth. This leads to a vicious cycle that can be prevented with proper farm pond aeration.
Farm pond aeration maintains good water quality by maintaining levels of oxygen in the water and preventing anaerobic decomposition. In addition, proper farm pond aeration provides for the proper living conditions for zooplankton, which consumes algae and helps keep its growth under control.
Planning for a Robust Farm Pond Aeration System
When making plans for a farm pond aeration system, it is important to consider many factors. For example, you should consider the size and depth of the farm pond, as well as its purpose. You must also consider how far the farm pond is from electrical sources and the amount of wind exposure it receives. You can also check your pond’s current levels of dissolved oxygen by purchasing a dissolved oxygen test kit.
Once you have assessed your unique situation, you can begin to develop a farm pond aeration plan. The most natural answer to providing proper farm pond aeration is to clear the pond of ice and snow in the winter so it can be properly aerated in the winter. Of course, this is not always feasible and it can even be dangerous. There are, however, commercially available deicers that can be used to assist in this process.
Other options for farm pond aeration included the use of perforated air hose diffusers. There are also a number of commercially available products, such as Koender windmills that use wind power to create bubbles beneath the surface of the water and aid in aeration.
