Why Aerate?

How does water aeration help cultivation?

A high oxygen level in the irrigation water is important for a healthy crop development. Too low oxygen levels can lead to harmful bacteria growth and accumulation in the piping system, to high nitrite levels and a poorer root development. In general, a minimum value of 3-5 mg / l of dissolved oxygen is held necessary for bacteria to be able to convert nitrite into nitrate. Healthy water contains 6mg O2 / l or more. Causes of low oxygen levels in irrigation water are:

  • Ground water containing iron has a low oxygen level.
  • RO water (reverse osmosis) containing volatile gases which ensure a low oxygen content.
  • Sand Filter Water loses much oxygen by filtration.
  • Rainwater that loses much oxygen by organic pollution.
  • CE water, (fertilizer enriched water) provide increased oxygen consumption.

Biological or rather organic pollution in the water creates microbial activity that takes out the oxygen. Certainly fertilizers are a cause for anaerobic problems because of the ammonium. Oxygen consuming microorganisms convert ammonium into nitrites, and then nitrates. If the oxygen level is too low the result is water with high concentration of nitrites and low oxygen levels. This is bad for the cultivation.

Applying an Oxydent aeration system is the best solution in these situations!
