PGA PGM LVL 2~TURFGRASS
MANAGEMENT EXAM QUESTIONS WITH
CORRECT ANSWERS
Mowing Requirements - Answer--The longer the grass the healthier it is
-Short heights are stressful for all grasses
-Grass has its growing point at the base of the shoot
-Removal of the shoot affects the turfgrass plant in a number of ways.
Removal of the Shoot - Answer-Reduction of leafy part of the plant (the shoot) resulting
in a reduction of the plant's ability to make its own food
-Reduction of root length resulting in a reduced ability to absorb water and nutrients
-Reduction in resistance to invasion by disease as cut blades of turfgrass is more
vulnerable
Types of Grass Determine its Tolerance to Mowing Heights - Answer--Greens
1/8"-1/4"
Often mowed daily, sometimes twice a day
High maintenance
-Tees
3/8"-1"
Mowed 2-4 times a week
Medium Maintenance
-Fairways
1/2"-1 1/4"
Mowed 2-4 times a week
Medium Maintenance
-Roughs
2"-uncut
Mowed weekely-once a season
Low Maintenance
Fertilizing - Answer-Of the 15 essential nutrients needed for turfgrass, nitrogen,
phosphorus, and potassium must be supplemented through fertilizers.
-On the bag the label reads 21.3.10 that means the fertilizer contains 21% Nitrogen 3%
Phosphorus and 10% Potassium (Always in that order) Fertilizer containing all 3
elements is known as COMPLETE FERTILIZER
Aerating - Answer-Soils are about 25% air, 25% water, and 50% solid. Soil compacts
through intensive traffic, foot traffic, golf cars and mowers
, Aerating Cont. - Answer-Aeration restores the passageways that facilitate the flow of
water, nutrients, and air to the plant. Includes removing 3"-4" cores of soil from the
ground
Dethatching - Answer-Thatch is decomosing grass stems and dead roots-accumulates
-Too thick a layer it must be removed because water, nutrients, and fertilizers cannot
penetrate down to the soil.
-Increases penetrability by the removal of a layer of organic matter that accumulates
just below grass blades and above the soil surface.
Topdressing - Answer-Placing soil over the putting surface to smooth and decrease
surface irregularity.
-Often used after aeration to fill holes.
-Topdressing can be used to slowly alter soil contents.
Overseeding - Answer-Planting cool season grasses over warm season grasses to
provide a green playing surface during winter months.
Herbicides - Answer-Treat weeds ex. Goose Grass, crab grass
Insecticides - Answer-Treat insects ex. Army Worms, grubs
Fungicides - Answer-Treat disease ex. Dollar Spot, pithuiom, fairy rings
Nemacides - Answer-Treat nematodes (microscopic organisims kills plant from inside
out)
Primary Information Superintendent and golf Professional need to communicate to the
customer - Answer-Inform
Educate
Listen
Inform - Answer-Post notes around clubhouse and the 1st and 10th tee telling
chemicals were applied today and they should not put their hands to their eyes before
washing
Educate - Answer-Superintendent and Head Pro have a meeting with the MGA to tell
them about aerofying process and why they must doo it
Listen - Answer-Head Pro overhears a member talking about a large gathering of birds
in the fairway of #7. Head Pro then knows we may have an insect problem and calls the
Superintendent to let him know right away.
Chemical Technician - Answer-License to buy chemicals. he does not need to be the
one applying the chemicals, just oversees the process.
