The options in turf establishment in
Ontario are basically sodding, seeding and hydroseeding. As
one assesses the sodding option from the standpoint of
immediate environmental benefits, there are several
significant dimensions:
Erosion Control - Sodding offers
immediate stabilization of the construction site thereby
avoiding significant loss of soil by wind or water erosion.
Water Conservation - Sodded turf
sites will require irrigation for a shorter period of time
after planting than sites which are seeded.
Reduced Herbicide Use - When
establishing a turf with quality sod, there should be no need
to apply a herbicide for weed control for two to four years.
Reduced Probability Of Failure -
Frequently, turf must be established on very adverse sites
such as impermeable clays, steep or stony sites and poorly
drained areas. Proper sodding has a much higher potential for
successful stabilization of the area with turf. Risk of
failure by seeding is great and may require repeat plantings.
Earlier Environmental Benefits -
Sodding offers a significant range of immediate benefits which
contribute to life in urban areas. These are listed more fully
in the following notes, "Benefits of Turfgrass."
