Managing Change July 14, 2022

Guelph, ON—14-Jul-22— Turfgrass Water
Conservation Alliance (TWCA) Is pleased to announce the in-person sessions at
Green Municipalities 2022. Beginning 10 am August 12
th the five
sessions highlight new cultivars, technologies and management practices helping
municipalities and turf managers adapt to the realities of climate change.


TWCA Tall Fescue Drought Evaluation:

  • This singles species trial includes 3 replications of 44
    entries and 6 standards
  • Each trial is named for the year in which it is established
    although data collection WILL NOT begin until the following year
  • Data collection runs for three years so a trial established
    in 2020 will collect data in 2021, 2022, and 2023
  • Data is collected using Digital Image Analysis (DIA)
    technology developed and refined by Dr D Karcher (U of AR) and K Hignight
    (NexGen)
  • TWCA conducts trials in Rainout Shelters (ROSs) and in field
    conditions:
  • In areas with a reasonable expectation of little to no
    rainfall during the summer months TWCA uses field trials
  • In areas where there is a moderate to high likelihood of
    rainfall during the summer TWCA uses ROS (Rainout Shelters) to control environmental factors more tightly
  • When using ROSs for trialing TWCA cooperators change the
    plastic covering on the shelter every year to ensure high light penetration
    into the trial
  • This 3-year trial is replicated in 10 locations

TWCA Kentucky Bluegrass Drought Evaluation (concluded):

  • This singles species trial includes 3 replications of 24
    entries and 6 standards  
  • Each trial is named for the year in which it is established
    although data collection WILL NOT begin until the following year
  • Data collection runs for three years so a trial established
    in 2020 will collect data in 2021, 2022, and 2023
  • Data is collected using Digital Image Analysis (DIA)
    technology developed and refined by Dr D Karcher (U of AR) and K Hignight
    (NexGen)
  • TWCA conducts trials in Rainout Shelters (ROSs) and in field
    conditions:
  • In areas with a reasonable expectation of little to no
    rainfall during the summer months TWCA uses field trials
  • In areas where there is a moderate to high likelihood of
    rainfall during the summer TWCA uses ROS (Rainout Shelters) to control ?
    environmental factors more tightly
  • When using ROSs for trialing TWCA cooperators change the
    plastic covering on the shelter every year to ensure high light penetration
    into the trial
  • This 2-year trial is replicated 10 times in 9 locations 

Fiesta
trial: 

This trial compares
two formulations of a low-risk herbicide, Fiesta, for
controlling broadleaf weed populations on lawn-height turfgrass. Specifically,
this trial will seed dandelions into the established turf stand to evaluate
early-emergent suppression of this pesky weed. 


Turf
Canopy Scanner: 

Light detection and ranging (LiDAR), also known as
"3D laser scanning", is a new technology that uses laser beams to
create a 3-dimensional topographical map of a surface. The Turf Canopy Scanner
is a device developed at the University of Guelph that uses LiDAR sensors
mounted onto a rover to scan the turf as it drives. Engineering graduate
student Arthur Rosenfield
 will
be using machine learning to create predictions for the rate of growth,
fill-in, and harvestability of sod. 


Beneficial Bacteria:

Beneficial bacteria which were isolated in the lab will be applied in the field to a creeping bentgrass fairway. Endophytic (endo=inside, phyte=plant) bacteria can be found in nearly every plant on this planet, where they colonize the internal tissues of their host plant and form a beneficial relationship with their host. Previous research on corn and wheat have demonstrated increased yield and improved disease resistance. Now, this project is applying the same principals to turfgrass. Graduate student Ben McFayden is working with Dr. Manish Raizada on a project sponsored by the Ontario Turfgrass Research Foundation (OTRF) to boot nitrogen use efficiency and stimulate root growth for better water uptake. 




TWCA Announces Changing Climate, Changing Communities Panelists June 22, 2022





Turfgrass Water Conservation Alliance (TWCA) is excited to announce
the panelist for the Changing Climates, Changing Communities discussion at the Green
Municipalities Field Day event. The roundtable takes place from 1pm-2pm Eastern
and is the central component of the virtual event. Addressing the climate
challenges facing communities and the green industry are representatives from
government, industry and academia each presenting a unique approach and
viewpoint.

Friday August 12th at Guelph Turfgrass Institute,
the Green Municipalities Field Day is the first live event for TWCA since 2019
and is the first international field day event for TWCA. Originally scheduled
for August 2020, this long anticipated event includes live and virtual
components to facilitate easier access and greater inclusivity and
accessibility. Hybrid attendees will also participate in field trial tours,
enjoy lunch compliments of sponsor,
TMI,
and enjoy a refreshing beverage at the TWCA reception afterward.



Panelists:


 John Cochran, owner of Turf
Merchants International –

Developing, producing and marketing turf grass seeds for the
United States, North America and more than 20 other countries around the world,
our varieties have topped the National Trials many times, as we have focused on
achieving superior performance in:

  •  Wear Tolerance
  • Disease Tolerance
  • Drought Tolerance
  • Reduced Maintenance


Alex Dickie of Zander Sod-

Fred Zander started Zander Sod Co. Limited when sod was harvested,
loaded, and unloaded by hand!

Nowadays,
we have automated harvesters that cut, roll, and pile the sod directly onto
skids. We have forklifts to load sod onto trucks, automatic tarping systems on
our trailers, and truck-mounted forklifts to efficiently offload products at the
homes and businesses of our customers. Times have certainly changed.

As
much as technology has changed our business, three constants over the years
have been our dedication to providing quality turf, exceptional customer
service, and great value for our customers.

 


Stephanie Duer, Conservation Programs Manager at Salt Lake City Department
of Public Utilities (SLCDPU)-

As climate change continues to impact the southwestern US,
72% of Utah is under extreme drought with the remainder of the state under
severe drought conditions. And while there is always uncertainty in the climate
outlook, the Utah Climate Center has stated that residents of the state must
prepare for and adjust to an ongoing drying trend across the region.

SLCDPU has identified the need to reduce outdoor water use by 15 percent
by 2030. Surveys have indicated that, while many households and commercials properties
are open to modifications to their landscapes, there are still a significant
percentage of property owners/managers that resist relinquishing the lawn. Though
Utah is generally considered a desert climate, the higher elevation of the
service area precludes a full desert plant palette while supporting turfgrass.
The issue isn’t that lawns exist, rather the wrong lawns exist.

 


Kelly Kopp Professor and Extension Specialist in the Plants, Soils &
Climate department at Utah State University- 

Kelly Kopp is a Professor and
Extension Specialist in the Plants, Soils & Climate department at Utah
State University, where her research efforts are focused on landscape water
conservation and sustainable turfgrass management. She serves on the Board of
Directors of USU's Center for Water Efficient Landscaping and is board member
and past president of the Utah Water Conservation Forum. She works directly
with many of the federal, state, and municipal agencies that are working toward
achieving water use efficiency in the state of Utah, the Intermountain West,
and beyond
.

 


Jack Karlin, Program Administrator, Turfgrass Water Conservation Alliance
(TWCA)-

Jack is the Principal at Karlin
Consulting llc, and Program Administrator of TWCA since 2014.  His primary
interest is the role of regulation in enhancing the sustainability and
livability of the managed environment. Jack received his B.S. in Environmental
Science from Oregon State University where he specialized in Water Science and
Policy.  He is a small grants reviewer for the Mid-Willamette Valley
Watersheds group for the Oregon Watershed Enhancements Board.
