Sand Modified Root Zones
The interface between FINE sand,COARSE sand and GRAVEL produces:
A Perched Water Table
Especially useful for SLOPES, keeps SEED MOIST and in place:
Hydromulching
Planting stems that have AT LEAST ONE NODE OR CROWN and perhaps attached roots and leaves:
Sprigging
Often used for St. Augustine and zoysiagrass, HIGH LABOR REQUIREMENT, but is a way to reduce the amount of planting material needed for vegetative ESTABLISHMENT:
Plugging
May be done any time of year if irrigation is available, but is EXPENSIVE:
Sodding

You want to plant PERENNIAL RYEGRASS in the FALL to cover some BARE AREA of your lawn:
Seed
You have a NATIVE CLAY SOIL and you want a ST. AUGUSTINEGRASS LAWN:
Regular sod
Used as OVERSEEDING in the FALL, germinates quickly from LARGE SEEDS, exhibits great quality, and transitions gradually in SPRING or EARLY SUMMER:
Perennial Ryegrass
FINE textured
Light green color
small seeds
dies suddenly in early spring:
Rough bluegrass
Rapid establishment
from large seeds
exhibits poor quality from light green color and coarse texture
Inexpensive
Grows very rapidly in spring:
Annual Ryegrass
The BIGGEST GRASSY WEED PROBLEM in overseeded turf:
Annual Bluegrass
Occasionally used for OVERSEEDING,
Most often used as a PERMANENT PUTTING GREEN SURFACE:
Creeping Bentgrass
T/F
It is adviseable to withhold water b/c the cool season grass needs more water:
F
T/F
There is a chemical transition aid that helps on sod farms and golf courses:
T
T/F
Close mowing in spring is good b/c it allows sunlight penetration:
T
T/F
Best if it occurs rapidly:
F
Overseeding mixture LEAST likely to be successful:
Rough Bluegrass & Centipedegrass
Measureable effect on mowing practices on TURF:

All of the following are corrections for restricted water infiltration EXCEPT:
a)soil amendments b)aeration c)vertical mowing d)increased fertility e)wetting agents
D) Increased Fertility
Evepotranspiration is DECREASED by:
