Regrassing Greens Project Begins

On Monday we began our greens regrassing project with a deep tine aeration followed by conventional aeration.  We want to put as many holes as possible in the soil profile to improve gas penetration to achieve soil sterilization as deep as possible. In the picture you can see the aerator with the 3/4" x 10" tines and the resulting hole pattern.

Following the aeration the gas delivery tubes are placed on the green and then the green is covered with an impermeable plastic cover and the edges sealed so no gas can leak from under the cover. Once the green cover is sealed tight a computer controls the proper dose of methyl bromide gas that is pumped through the delivery tubes.  The covers will stay in place for a minimum of five days.
