Dr. Frank Rossi: Frankly Speaking

Dr. Bill Kreuser: Clipping yield and managing turfgrass growth

Posted in Tech Turf Talk, Frank Talk, By the Numbers 17 May 2018 · 1,038 views

In this episode, my old pal Dr. Bill Kreuser of the University of Nebraska-Lincoln returns for another visit to the Frankly Speaking virtual studio. We have a fascinating discussion about the current knowledge base about measuring clipping yield, GDD modeling, PGR use and managing for consistent turfgrass growth and optimal turfgrass health.


Is the "one-third rule" valid, or completely bogus? What happens at 50%? Where is the optimal interface of mowing height and frequency? How to use clipping yield to guide fertility and PGR use so you're not "driving down the road with one foot on the gas and the other on the brake..."


How about collar decline... should we be mowing our collars lower? Bill says, "YES!"


Spend a few minutes with Dr. Bill Kreuser and me to expand your knowledge base about managing turfgrass growth.

In this episode of Frankly Speaking -- Resistance Radio, Summer Edition -- I talk New England sports and relate it to turf management with Boston sports fans Dr. Ben McGraw, entomologist at Penn State University and Dr Jim Brosnan, weed scientist at the University of Tennessee.


Topics include data-driven precision weed management, synchronicity of adult pest populations, fraise mowing for weed management via seed bank reduction, and the effect of insect control methods on pollinators.

Brian Whitlark: Factors affecting playability of putting surfaces

Posted in Tech Turf Talk 17 June 2017 · 1,698 views

In this episode of Frankly Speaking, I have a fascinating chat with Brian Whitlark, western regional agronomist for the USGA Green Section, about factors influencing playability of putting surfaces. On the table for discussion are green firmness, angle of approach from the fairway vs the rough, slope of the green, ball roll distance/green speed, and mower setup.


Whitlark is a certified professional soil scientist and has worked extensively with golf courses facing challenging soil and water conditions. Since joining the Green Section, Whitlark has conducted applied research in a variety of areas, including mitigating saline and sodic soils, evaluating practices to produce quality putting surfaces, exploring the pros and cons of using turf colorants and optimizing mower setup. He has written extensively for practitioners in the areas of soil, water and soil test interpretation.


Whitlark is a graduate of the University of Arizona at Tucson, where he received his Bachelor of Science and Master of Science degrees from the Department of Soil, Water and Environmental Science, with an emphasis in turfgrass science. 



As always, smart talk from leading thinkers, presented by DryJect.


Turfgrass science from an engineer's perspective... with Dana Lonn of The Toro Company

Posted in Tech Turf Talk 01 April 2016 · 1,447 views

My guest in this episode of Frankly Speaking is Dana Lonn, PE, Managing Director of the Center for Advanced Turf Technology at The Toro Company. We discuss how the new technology in turf -- sensing, mowing, irrigation, energy/power sources -- will start driving demand and precision.


Turfgrass science from an engineer's perspective is the underlying premise of this discussion and as always "smart talk from leading thinkers" in the turf industry.


Frankly Speaking is presented by DryJect.


Dr. Bill Kreuser: PGRs, growth potential and timing

Posted in Tech Turf Talk, Frank Talk 22 October 2015 · 1,802 views

In this episode I Speak Frankly with Professor Bill Kreuser from the University of Nebraska-Lincoln about his work with PGRs (rates, frequency, etc), pigments, and his take on using growth potential to schedule fertilizer programs.
