  2. If managers are aerating once a month, will this not break up the barrier that your permanence creates? If so what do you do?
  3. What are your best practices for aerating? Hole depth, frequency, how do you decide?


What are the advantages/disadvantages between of solid tine versus core aeration?

"Hollow core aeration effectively relieves compaction by removing soil. Solid tine aeration, while certainly creating air, H2O, and nutrient access, will cause some horizontal compaction. "
Matt Conti - Princeton University, Princeton, NJ

If managers are aerating once a month, will this not break up the barrier that your permanence creates? If so what do you do?

"You want to aerate past your barrier to allow water and air to penetrate past the barrier. "

What are your best practices for aerating? Hole depth, frequency, how do you decide?

"* If core collection is desired while cultivating, an inexpensive option is dragging a heavy tarp behind the cultivator. The cores lifted from the playing suface land on the tarp and are easily removed. No raking required!"
Jason Henderson, Grad student at MSU, East Lansing, MI

"For the Las Vegas 51's Cashman Stadium, our practice is to aerate once every away stand with a sports turf tine."
Rod Smith - LVCVA, Las Vegas, NV

" We aerate with hollow tines at the beginning and end of each athletic season, baseball, football and soccer. 1/2 inch by 3.5 inches deep. We knife aerate once a month during each season respectively, 4-6 inches deep. "
Keith Gorczyca - Carol Stream Park District, Carol Stream, IL

"We are aerating six times with half-inch solid tines April - September, and whenever the ball team is out of town. We are aerating at a 3 to 3-1/2 inch depth with hole spacing 76mm per hole."
Justin Spillman and Rusty Reese - Altoona Curve/Blair County Ball Park, Altoona, PA

"I use a variety of aeration equipment. The soil makeup and moisture content will dictate which piece of equipment I use. Hollow tine aerater, shattertine aerater or my favorite the Aerivator by First Products. Hit your fields at least once a month for best results. "
Lance Tibbetts - Recreation Dept., Westbrook, ME

"We deep tine up to 4 to 16 inches, which promotes deep watering and active root growth. Slicing - short lived, but excellent during playing season."
Domingo Castillo - Irvine Unified School District, Irvine, CA

"Frequency for aerating depends on soil type, compaction, and porosity. Note: Sand base fields can be punched and not cored. Hole depth approximately 4" deep."
Chris Collins - Advanced Microbial Solutions, Pilot Point, TX

"At the end of the fall season, November, we aerate with a plug or spoon type machine 6 - 8 times over at a depth of 4 - 6 inches. We leave the plugs on the surface during the winter. In spring, we aerate again 2 - 3 times over, this time dragging the plugs back over the holes. During the growing and athletic seasons, we aerate periodically 1 - 2 times over with a solid tine machine. This type of aerator disrupts the surface very little, allowing aeration to take place without interfering with play."
Kevin Yeiser - Lebanon Valley College, Annville, PA

"We core aerate 3 times a year, 1/2 inch tines, 3 - 4 inch depth. We solid tine aerate 1 time a year using 1/2 inch tines, 8 - 9 inch depth. We solid tine 2 times a year, 3/4 inch tines, 8 - 9 inch depth. We time the application with our baseball schedule, 1/2" tines 8-9 inch depth. "
Heather Nabozny - Comerica Park, Detroit Tigers, Detroit, MI

"Aerate compacted soils or thatched turf when grass is actively growing with 1/2" - 3/4" hollow tines. Aerate 1" below root depth or desired root depth."
Stephen Guise - Guise & Associates, Fullerton, CA
