TURFGRASS MANAGEMENT EXAM
QUESTIONS WITH CORRECT ANSWERS
false - Answer-hydrogen, oxygen, and nitrogen are the three primary nutrients
necessary for plant growth
true - Answer-short mowing causes shallow root systems
increase oxygen space in the soil, too loose - Answer-what is a predictable
consequence of adding sand to clay soils?
clay soil - Answer-what type of soil has the best retention properties of nutrients needed
by plants?
soil texture/ loam is an ideal soil - Answer-what determines if soils have a good balance
between drainage and water retention?
suffocate - Answer-what will Turfgrass plants most likely die of if planted in dense clay
soil under extremely wet conditions?
hold nutrients better than sandy soils, but it can be too dense. - Answer-describe the
characteristics of clay soils
clay soil in a tight traffic area - Answer-provide an example where compaction is most
likely to be a problem
nitrogen, phosphorus, potassium - Answer-packaged golf course turf grass fertilizers
contain what combinations of macronutrients?
false - Answer-due to the high level of traffic they receive, fairways are usually planted
with fescues
true - Answer-the fescues are cool season grasses
true - Answer-grasses with stolons or rhizomes are best for filling divots
true - Answer-facilities with large crews and high maintenance budgets will select
different grasses than those with more modest staffing budgets
true - Answer-Bermuda grass will go dormant and turn brown below 50 degrees F
true - Answer-warm season grasses will die out in temperatures much below 50
degrees F
, false (acidic) - Answer-Clay soils tend to be alkaline
true - Answer-golf courses located in the transition zone of the United States can use
either or both warm and cool season grasses
false - Answer-transition zone facilities are more likely to rely on overseeding to
maintain year round green playing surfaces than facilities in other geographic locations
false - Answer-mowing height is almost always the only difference between the grass in
the rough and the grass in the fairway
requirements for fertilizer & water - Answer-what is the overriding selection criterion
used by designers and superintendents when considering all the Turfgrass options
around their course?
geographical location - Answer-what is the most important agronomic consideration
when selecting the types of Turf grasses to be used on a golf course?
adds color to green - Answer-why might ryegrass be used on a course located in
Florida?
it can tolerate low mowing - Answer-why might a fairway be planted with perennial
ryegrass?
germinates quickly - Answer-why is perennial rye grass paired with other grass species
in divot repair mixes?
perennial rye grass - Answer-which grass species is commonly used for over seeding
dormant warm season grasses?
adapts quickly - Answer-why might annual ryegrass be selected to over seed?
decrease maintenance requirements - Answer-why might Kentucky Bluegrass be used
for fairways instead of creeping bent grass?
a species cannot be patented/ a cultivar can be (color, density, thickness) - Answer-
what is the difference between a species and a cultivar?
a sandy soil - Answer-what do you call a soil that has larger particles and allows water
and essential nutrients to leach through?
maintenance budget - Answer-what is an important consideration in selecting turf
grasses for a new golf facility?
False (caused by soil compaction) - Answer-the loss of adequate air supply to the root
zone is most commonly caused by poor irrigation practices
