under well-watered conditions. While
the application of ABA is not currently
reasonable on a large scale, the results
may lead to better breeding of turfgrass
that preserve water in the soil and can go
longer between irrigation events.
A PhD candidate at the University of
Guelph associated with the GTI, Nancy
Xiao, is also looking at how factors
such as nutrient availability and mowing practices will affect the irrigation
needs and water availability of turfgrasses. The research is funded with
the support of the Canadian Turfgrass
Research Foundation and is also part of
a project that is funded by the Turfgrass
Water Conservation Alliance. The question of how nitrogen affects water use
came about when Dr. Lyons was visiting German Greenkeepers and they
commented on how they increased
nitrogen fertility to aid in drought tolerance. This is different than what we are
taught in North America: the general
belief here is that increasing nitrogen
rates increases lushness of the shoots
and reduces root growth, resulting in
greater irrigation needs and a reduction
in drought tolerance.
To test the water use of the turfgrass,
Xiao has been using growth chambers
(Figure 1) to measure the water loss
under different management regimes.
Growth chambers create unique environments that can greatly over-estimate
the water use of turfgrasses. This may
contribute to the belief that turfgrasses
are heavy water-users. In order to measure actual water use and calculated ET
in the chambers, Dr. Michael Chang, a

postdoctoral researcher who specializes
in micrometeorology and plant growth
at the GTI, has developed novel scientific devices that can be used to answer
Xiao's questions. While these instruments are currently being used primarily for research, they may someday find
their way into your operations to better
predict water needs and other factors
affecting water use.
This past summer revealed deficiencies in irrigation systems. As turfgrass
managers with irrigation systems struggled to deliver enough water to their field
to keep them actively growing during
the drought, it became a great time to
observe issues regarding a lack of sufficient pressure in the system. If there

is not enough pressure in the system,
the pattern of delivery becomes altered
and portions of the field are overwatered
and other portions are underwatered
(Figure 2). If possible, reduce the number
of heads on at any time to maximize
efficiency of delivery of water. Rather
than trying to water every field every
other night, attempt to water them every
third or fourth night. This will allow the
best coverage on every field.
Green turf on sports fields has been correlated to field hardness and therefore the
relative safety of fields. Irrigation systems
and water resources are a key element
to field safety and playability. The more
training that can be had on optimizing
irrigation resources and knowledge about
turfgrass water needs will help operations
deliver safe playing fields with the best
use of resources.

Professor in the Department of Plant
Agriculture at the University of Guelph
where he specializes in nutrient management, stress physiology and plant competition in sports field, golf course and
landscape turf. In addition, he oversees
extensive testing of new emerging products
for turfgrass managers and has authored
or co-authored in excess of 50 scientific,
extension and trade articles in the field of
turfgrass science and management.
