Venting/Hydrojecting Greens Today

In an effort to keep our greens in the best shape possible health wise during the summer, we vent our greens every few weeks.  Mr Webster describes to vent is to provide an outlet for air, gas and liquid Exactly the three things we are trying to accomplish when we vent our greens.

The first venting occurred around  June 1st with a needle tining using our large tractor and verti-drain machine. The next two applications including today's are made by E&E Enterprises, a contracted service who provide three hydroject machines to our site. A row of 3000 psi streams of water are shot into our greens creating a near pencil sized hole that goes about 4-5" deep into the sand profile.

The greens were top dressed with sand before the venting, we then rolled them and brushed them after the hydrojecting was completed.

Below is an explanation of how air, gas and liquid are effected by this venting action taking place in our green profile.
  • The vent hole allows oxygen to enter the green sand profile improving the health of our roots and encouraging microbial activity.
  • CO2 gas/carbon dioxide can build up in the soil and the venting holes allow this trapped gas to exit.
  • The holes allow excess water to move through the profile quicker and at the same time if we were dry would allow moisture to enter the complete profile much easier. The vents also will help dry out our saturated sand profiles.
  • The vents also help in reducing the temperature of our sand profiles, especially when they are holding water. Moisture is a great conductor of heat and will artificially warm up the soil much quicker when it is saturated than if the soils are at average moisture levels. As the soil profile increases in temperatures over 80-85 degrees, root hairs begin to die which are the structures where most water and nutrients enter into the plant. The less root hairs functioning, the more stress a plant will experience.
