Learn How Every Lawn is Different
To the untrained eye, all lawns look the same; just a big area of cut grass. Grasses can vary greatly though. Some are hardier or more disease resistant, some have thicker leaf blades, and some creep along the ground while others grow upright.
Even grasses that are called the same name are not necessarily the same. The term couch grass (for example) is commonly applied to fine leaved creeping grasses of the genus “Cynodon”; but it is also occasionally used loosely to describe fine leaved grasses from other genera. Grasses that may be called couch include:
- Couchgrass or Bermudagrass - Cynodon dactylon
- South African Couch - Cynodon transvaalensis
- Hybrid Couch - cultivars selected from cross breeding Cynodon dactylon with Cynodon transvaalensis
- Queensland Blue Couch - Digitaria didactyla
- Salt Water Couch - Paspalum vaginatum
Even within each of these species there can be different varieties with varied characteristics.
Learn how every lawn should be treated differently
Through this course you will begin to learn how different cultivars of grass should be used and treated. Some are more suited to playing sport on, some look greener, and some can be mown lower so balls will roll better on the surface.

Scope of the Turf Industry
A park, golf course, bowling green, race track, garden or other public space with well maintained grasses areas is not only visually appealing, it creates a sense of space and restfulness when combined with other elements in the landscape. The turf industry services public and commercial spaces such as these, and also turf in private gardens.
More people work in turf than what people might imagine, from superintendents and green keepers, to pest control contractors, seed suppliers and machinery salesmen; and these are only some of the opportunities that may open up to a graduate in turf care or management.
A healthy and vigorous lawn also provides the following benefits:
- every 2-3 square metres of grass produce enough oxygen for one person for a day
- lawns have a cooling effect on the immediate area
- lawns absorb carbon dioxide emissions from nearby vehicles
- lawns reduce noise by absorbing and deflecting sound
- lawns reduce glare
- lawns reduce water runoff through absorption
- lawns improve the soil processes and general soil condition
A turf is a low-growing ground cover. The type of plant used in the turf may be a single variety or a mixture of plant varieties. It might be cut regularly or only rarely to maintain a desirable and even height. While grasses are the most common groups of plants used for turf, a very wide variety of other types of low growing plants have been used successfully, including clovers, Dichondra, thyme, and chamomile. These notes will concentrate on grass turf.
There are three main reasons for which turf is created:
a) Functional turf is used to control soil erosion, reduce dust and mud problems, reduce glare, noise, air pollution and buffer temperature fluctuations. Turf along a roadside or surrounding a factory are examples of functional turf.
b) Recreational turf is used for sporting activities, such as bowling greens, golf courses and football grounds, and other outdoor recreational activities such as surfacing a children's playground or picnic area.
c) Ornamental turf is primarily intended as a decoration, for example the front lawn of a home or office building or high quality grassed areas in public parklands.
NOTE: some turf might be created for a combination of reasons, and as such do not fit exclusively into one of the above categories.
