material and support water conservation is:
a. landscape irrigation
b. an irrigation system
c. an irrigation design
d. good for business and the environment - Answer✔a. landscape irrigation
the rate (or speed) at which soil will accept water. The speed at which water can penetrate or
infiltrate the soil. Also called percolation or infiltration rate. As the soil "capacity" is reached,
the absorption rate will decrease. It is affected by soil type, slope, run-off, etc. Different soil
types absorb water at a different rate. - Answer✔absorption rate
the depth of soil in which a plant extracts most of the water it needs for evapotranspiration -
Answer✔active root zone
The operating pressure measured at the base of a sprinkler head. Actual head pressure is
calculated by deducting total pressure losses from the static water pressure. ---- has to be equal
to, or greater than, the minimum head pressure, for a given sprinkler head to function correctly
- Answer✔Actual head pressure
An approved ---- is the unobstructed vertical distance through free atmosphere between the
lowest pint of water supply outlet and the flood level rim of the fixture or assembly into which
the outlet discharges. There vertical, physical separations must be at least twice the diameter
of the water supply outlet, but never less than 1 in. - Answer✔Air Gap
Small device used on some subsurface drop irrigation that allows air into the dripperline when
the system is not running which eliminates any vacuum that could result in debris or
contaminants being sucked into the piping system - Answer✔Air/Vacuum Relief Valve
The amount of water, in irrigation management, that is allowed to be depleted from the plant
available water before an irrigation event is scheduled. Also referred to as Managed Allowable
Depletion (MAD). Generally, 50% depletion is the rule of thumb - Answer✔Allowable Depletion
(AD)
An electric current that reverses it direction periodically - Answer✔Alternating Current (AC)
Any device that introduces air into the system to prevent "back siphonage." - Answer✔Anti-
Siphon Device
Rate at which water is applied by sprinkler heads in a certain pattern. Usually measured in
inches per hour, gallons per hour or gallons per day. Commonly called "precipitation rate". -
Answer✔Application rate
What are the three methods in which to evaluate application rates? - Answer✔1. a densogram
