Apron

The front area between a green and the fairway.

Bunker

A hazard consisting of a depression area of bare ground usually covered with sand.

Collar

The zone surrounding the green ranging from two feet to several feet wide.

Fairway

The area between the tee and green with a mowing height of 1⁄4 to 1 inch.

Hazard

Any bunker or water hazard. Roads, cart paths, and trees are not hazards.

Practice green

The green area of a golf course used for practice putting and usually placed near
the clubhouse.

Putting green

The area to putt the ball into the hole.

Rough

The area that surrounds the putting green, fairway, and tees and provides the background
which the game is played. They are covered with turf-grasses.

Tee

The area to start a hole. A tee is mowed at 3/8 to 3⁄4 inches depending on type of turf-grass
used.

Creeping bent grass cultivars

Only putting green turf-grasses used in the northern and transition zones.

Hybrid Bermuda grass cultivars

Only putting green turf-grass in southern regions.

Creeping Bent grass, Kentucky bluegrass

Suitable turf-grasses for tees in cool regions.

Bermuda grass, Zoysia grass

Suitable turf-grasses for tees in warm regions.

Bent grass, annual bluegrass, Kentucky bluegrass, perennial rye grass, fine fescues

Suitable
turf-grasses for cool season fairways.

Bermuda grass, zoysia grass, seashore paspalum

Suitable turf-grasses for warm season fairways.

Golf course rough grasses

All cool season and warm season turf-grasses suitable for lawns are suitable.

Mowing

Is the most common practice to prepare the playing surface.

Mowing a green

Is the most critical step in preparing the putting surface and it requires training
and experience.

Essential mowing practices

Straight cutting lines, proper overlaps, proper turns, and uniform mowing patterns are essential
for all mowing practices on golf courses.

Golf course rough grasses

All cool season and warm season turf-grasses suitable for lawns are suitable as golf course rough
turf-grasses.

Mowing

Is the most common practice to prepare the playing surface.

Mowing a green

Is the most critical step in preparing the putting surface and it requires training
and experience.

Essential mowing practices

Straight cutting lines, proper overlaps, proper turns, and uniform mowing patterns.

Walk-behind or reel mower

Is used to mow greens at a mowing height range of 3/16 to
1/10 of an inch.

Proper setting

Of the mower is critical for the mowing quality.

Clipping on putting greens

Due to the required playing surface, clippings are removed from putting greens.

Scalping

Frequently emptying mower baskets of clippings will reduce the impact to the soil and the
potential of scalping.

Cleanup pass

A mowing cleanup pass at the edge is critical to have a neat appearance.

Daily mowing

Greens, tees, and fairways are commonly mowed on a daily basis.

Putting green mowing frequency

If it is necessary, the putting greens are mowed twice a day.

Dew evaporation

Allowing dew to evaporate before mowing reduces disease potential such as dollar spot and
results in a better cut.

Safe operation

Safely operating mowing equipment is essential for all operators.

Proper training

Is required for new employees without mowing experience on golf courses.

Sharpness and maintenance

Of mowing equipment is needed.

Clean up

Thorough clean up of mowing or other equipment after mowing is a basic work ethic.

# of essential elements that come from soils

Plants require 16 essential elements to grow. A shortage of any of these 16 elements will cause nutrient deficiency in a plant. Among the 16 essential elements, 13 of them come from soils.

Nitrogen, phosphorus and potassium

Are required by plants in the greatest quantities and these three often become deficient. So these three elements are added to a lawn as fertilizers.

Soil test

Is high recommended for golf courses on a regular basis such as once every three to
four months.

Creeping bent grass green fertilizer

For a creeping bent grass green, an annul fertilization of 4 to 6 lb N/1,000 sq. ft. is recommended.

Creeping Bermuda grass green fertilizer

For a creeping Bermuda grass green, an annul fertilization of 4 to 10 lb N/1,000 sq. ft. is
recommended

Tee or fairway fertilizer

For a tee or a fairway, an annual fertilization of 2 to 5 lb N/1,000 sq. ft. is recommended.

Rough fertilizer

For a rough, an annual fertilization of 1 to 3 lb N/1,000 sq. ft. is recommended.

Tee, fairway, or rough Bermuda grass fertilizer additions

If the tee, fairway, or rough, is planted in Bermuda grass, add one to two pounds for season.

Never…

Never apply more than 1 lb N/1,000 sq. ft. at one single application.

Spoon-feeding

Is highly recommended for all golf course areas.

All Organic fertilizers

(Except urea) are slow release fertilizers.

All inorganic fertilizers

Are quick release fertilizers

When are Cool-season turfgrasses fertilized?

In the spring and fall.

When are Warm-season turfgrasses fertilized?

In the summer.

Recycling clippings

Can save as much as 50% of the required fertilizers.

Excessive fertilizer application

Can cause fertilizer burn and a negative impact on the
environment.

Impact on the environment of fertilizers and pesticides

Based on many scientific research results, the impact of fertilizers and pesticides on the
environment is minimal with proper fertilization and pesticide application to a turf area.

Safety

It is safe to use fertilizers and pesticides if the label instructions are followed.

Fertigation

Practice used to fertilize a golf course when irrigating.

Type of irrigation system for greens

Underground sprinklers.

Irrigating greens

By irrigation systems and hand watering.

The highest irrigating frequency for greens

Daily.

Highest syringing frequency for greens

Several times a day by hand or the system.

Impact

The quality of irrigation is influenced by many factors, such as irrigation frequency
and intensity. Infrequent and deep irrigation is highly recommended. Frequent and light
irrigation causes shallow root systems and surface moisture for diseases.

Proper time of irrigation for greens

Early morning.

Degree of irrigation required for greens

High.

Degree of training and decision making required for greens

High.

The most challenging part for greens

Reducing the negative impacts to a minimum.

Type of irrigation system for tees and fairways

Underground sprinklers.

Irrigating tees and fairways

The irrigation system.

The highest irrigating frequency for tees and fairways

Weekly.

Proper time of irrigation for tees and fairways

Early morning.

Degree of irrigation required for tees and fairways

Low.

Degree of training and decision making required for tees and fairways

Medium.

The most challenging part for tees and fairways

To reduce the negative impacts to minimum.

Irrigation systems for roughs

Only some high maintenance golf courses have an irrigation system for roughs.

Aeration

A practice used to improve soil conditions by removing soil cores or slicing the soil without destroying the lawn. Methods include coring, slicing, hydro-jet, vertical cutting, and De-thatching such as solid tine and deep drill.

Coring

Method of turf cultivation in which soil cores are removed by hollow tines.

De-thatching

Any method used to reduce the thatch layer of a lawn.

Hydro-jet

A method using high pressure (5,000 psi) water injection into the turf to loosen soil compaction without producing soil cores and destruction of the playability.

Soil compaction

A problem on golf courses due to the intensive traffic of 20,000 to 50,000 golfers on a course per year. Traffic control is a common practice on golf courses.

Biostimulants

Plant growth promoters extracted from other living organisms containing one or more types of plant hormones.

Plant growth regulators

Chemicals that can either reduce or promote the growth of turf-grasses, improve turf quality, or suppress weeds.

Color agents

Used to draw lines or make marks on golf courses for tournaments. Iron liquid fertilizer between 2 to 4 oz. per 1,000 sq. ft. is also often used to improve turf-grass color within rows.
