PGA PGM 3.0 Level 2 Turfgrass Management A Exam 100%
Pass 2024-2025
Where is the turfgrass growing point located?
Below the tip, at the crown
Why can grass plants be repeatedly mowed and still grow back?
Because unlike other plants, the growth region is subapical (below the tip)
Which are parts of a grass plant's shoot?
The parts of the plant above the ground, stem, leaves, flowers, seed heads
Where does new growth of a grass plant occur?
Below the tip, at the crown
What is a rhizome?
Stolons
Stems that grow sideways below the ground
What is a stolon?
A stem that grows above the ground
What is the lower part of a grass leaf called?
Sheath
True or False
,Soil pH is a measure expressing the water retention coefficient of a soil sample. (T/F)
False
it is a measurement of the acidity and alkalinity of the soil
True or False
Heavy clay soil has the advantage of resisting compaction problems in heavy traffic
areas. (T/F)
False
heavy clay soils have more of a compaction problem
True or False
Respiration refers to the process by which plants convert food into energy. (T/F)
True
True or False
Natural rainfall must be supplemented in most climates throughout the continental
United States. (T/F)
True
Natural water supplies is inadequate for golf course turfgrass
What is it that determines the nutrient and water holding ability of the soil?
The composition and texture of the soil
Under what circumstances are nutrients less available to turfgrass plants?
Sandy soil- allows water and nutrients to penetrate and pass through too readily, too
acidic or too alkaline
, Why would the superintendent be applying lime to the fairways?
To reduce acidity and raise the soil pH
What does a pH reading measure?
The relative acidity and alkalinity of the soil
What could you apply to alkaline soil to favour good turf growth?
Sulfur
What is the optimal pH range for most turfgrasses?
6-6.5
A soil pH measurement of 3 indicates what about the soil?
The soil is acidic
What is the result of having soil that is too acidic or too alkaline?
It tends to keep nutrients from the plant
True or False
Nutrient availability to turfgrass plants is optimum when the soil pH is 5.5 or below. (T/F)
False
between 5.5 and 7.5
True or False
The water holding capacity of loam is directly related to the amount of organic matter it
contains. (T/F)
