Figure 2a & 2b. Precipitation data summed every seven days for days between sampling
dates. a) Mean soil VWC measurements. While the error bars are present, they are too
small to be seen on the figure. b) Mean surface hardness measurements. The line at
100 g represents the surface hardness threshold that may pose a safety hazard.

recovering from wear from user groups.
Green turf is also competing with weeds
by growing into the voids left by excessive use.
During the summer of 2016, water
restrictions were implemented in the City
of Guelph that included the stopping of
watering of irrigated sports fields. The GTI
has two in-use sports fields at the research
station and we decided to measure the
effects drought had on turfgrass colour and
safety of the sports fields. As they experienced the drought, areas of green and
brown turf appeared as is common when
turf undergoes drought (Figure 1). As soil
moisture was depleted, volumetric water
content of the soil was lower, although the
green areas of the turf and the brown areas
of the turf were similar in volumetric water
content (Figure 2a). A surprising result was
that the areas under the green turf were
actually softer and therefore most likely
safer than the areas under the brown turf
(Figure 2b).
As sports fields become dry, they harden.
This occurs under both green and brown
turf. Surprisingly though the green turf
is softer than the brown turf (Figure 3).
This shows that green turf is not cosmetic
but serves as an indicator that the field is
not excessively hard. When the turfgrass
begins to brown, it is a sign that the field is
becoming harder and the addition of water
may help soften the field making it more
playable and safer for participants. During
water restrictions, the use of your irrigation
system should focus on the safety of the
players and maintenance of the turfgrass
playability. One good indicator of field hardness is dormant turfgrass and therefore
irrigation to prevent dormancy will help
maintain fields within the safe range with
respect to field hardness. It is important
during water restrictions to communicate
why irrigations is necessary and to irrigate
as infrequently as possible only to prevent
dormancy as water resources are valuable
and during times of limited water should
be preserved.
