28 Mar 2025Yay or Nay on Early Season Play?00:30:51

This season kicks off with a macro discussion about the experience of people who use turfgrass, and how it’s about more the quality of the grass. Those same people are itching to get out and play on golf courses and athletic fields, but without much active growth, should we let them? The turf guys debate allowing early season play considering the potential revenue, demand, and maintenance costs. They also discuss the role of synthetic turf in these shoulder seasons, highlighting their particular importance in urban areas where field demand is high.

Check out our turf Growth Potential Tool and Runoff Risk forecast to guide Spring maintenance.

04 Apr 2025Hot fields and cool Springs00:29:45

Dr. Arthur DeGaetano, Director of the Northeast Regional Climate Center, joins the show to discuss growing degree day accumulation in the Spring, and the annual variation in application windows for poa seedhead control and pre-emergent herbicides.

The show then moves to synthetic turf, with a primer on WHY synthetic turf gets so much hotter than natural grass. Wet bulb globe temperature is used by many governing bodies to determine activity levels for youth athletes, but does this account for heat stress when playing on synthetic turf? All that, and more on this episode of the Cornell Turf Show

11 Apr 2025The Science of Surface Firmness and Traction00:32:34

Dr. Evan Mascitti, Senior Engineer At Biocore, joins the turf guys in an epic conversation on firmness. Evan explains the intricacies of field firmness and traction, and how the soil AND plant properties influence these measures. The show takes a look at some recent data collected using The Beast, that shows how different surfaces perform under traction testing. We discuss how Biocore collects actionable data for NFL teams and grounds managers to improve athlete safety, and the importance of simulating the forces those specific athletes apply, which is often in excess of 200% of their bodyweight!
