Adjusted Application Rate Return to the top	Close
The average application rate is used to make an adjustment for the dry spots in the area measured that receives the lowest amount of water. The adjusted application rate is calculated by determining which of the 25% catch cans receive the least amount of water and determining the average application rate from 25% of the catch cans. Using the adjusted application rate helps to avoid any dry spots in a station, watering to keep the dry area wet, and over watering the rest of the area, wasting water.
Application Rate Return to the top	Close
The measurement of how much water is applied by the sprinklers (in one hour).
Average Application Rate Return to the top	Close
The measurement (in one hour) of how much water is applied in an area of the landscape added together then divide by the number of measurement catch cans. For example, if 10 of the catch cans added together equal 8.2 inches of water, your average Application Rate would be 8.2/10=.82 inches of water applied in one hour.
Controller Return to the top	Close
The controller is often refered to as the the timer, clock, or box.
Desired Root Depth Return to the top	Close
The depth you want your plant roots to grow in this station. Use the table below to help you make a decision:

	Annuals	Lawn	Perennials	Shrubs	Trees
1" to 6"	most	ok	ok
6" to 12"	some	preferred	good	ok
12" to 18"		excellent	preferred	good	ok
18" to 24"			excellent	preferred	good

Distribution Uniformity Return to the top	Close
A measurement of how even an irrigation system applies the water. 60%-80% is excellent 40%-60% is O.K. Below 40% is not good
Evapotranspiration Return to the top	Close
A measurement (often in inches) of water used by a plant and its Evaporation from surrounding area. It is a combination of evaporation and transpiration, also known as E.T. EvapoTranspiration is impacted by temperature, wind, humidity, and other various factors. It is measured on a daily basis but often refered to as a weekly amount. Water It Right uses daily Evapotranspiration.
Fixed Cylce/days Return to the top	Close
On a fixed cycle/days you choose the number of days per cycle/week you want to water. If 2 days are choosen the Irrigation Scheduler will calculate the amount of run time for ever two days on a cycle or twice a week when irrigation weekly.
Gallons Per Minute Return to the top	Close
The amount of water that is being used by the system when running.
Micro Climate Return to the top	Close
An area in the landscape that is shadier or sunnier than the rest of the landscape, which would use less or more water.
Plant Type Return to the top	Close
Each plant has a different Evapotranspiration Rate. Because of this, the runtime is adjust for the plant that is being watered.
Point Of Run Off Time Return to the top	Close
The Point Of Run Off Time is the amount of time that will pass before the water released by your sprinklers will run off the landscape and into the sidewalk, street, etc. The time is calculated by using the average application, the type of soil, and the slope. Setting your sprinklers to run no longer than the calculated Point Of Run Off Time will prevent the waste of water.
Program Return to the top	Close
Most controllers have several progams. The progams allow you to control stations on different cycles.
Runtime Return to the top	Close
The number of minutes to set each station on the controller.
Runtime Adjustment Return to the top	Close
This allows adjustment of the overall length of time to set the controller each time. This is used if the runtime is always off by a percent each time it is updated. Other adjustment can be made under edit station. Try adjusting the Micro Climate.
Sprinkler Type Return to the top	Close
There are several types of sprinklers heads; spray heads, Rotor heads. Impact Heads, Low volume; Drip tubing, Drip Emitters, Drip sprayers.
Square Feet Return to the top	Close
The amount of square feet covered by one Station. .
Slope Percentage Return to the top	Close
The percentage that measures the rate at which the station drops in elevation. To calculate the slope percentage: • Measure out level from the high point of the station approximately halfway accross the station. • Divide the drop in elevation by the distance across the station. • Multiply the result by 100. This is your percentage.
Soil Depletion Rate Return to the top	Close
The percentage of water in your soil that you want to be used before you water again. By selecting a higher percentage (such as 75%) it conserves water and encourages plant roots to grow deeper for water. Many plants prefer this to help develop healthier roots. This may occasionally cause a dry spot. By selecting a lower percentage (such as 50%) decrease water savings and dose not incourage deeper roots. Some plants may not like to be keep this moist with may damage their roots. This will most likly keep you soil moist not conserving water. Selecting extremely low percentages (such as 25%) wastes water and does not encourage root growth. Many plants do not prefer to be this wet as their roots will rot and may cause plant disease. This will make the soil a swamp, wasting water. Selecting extremely high percentages (such as 90%) is generally not recommended as this may put too much stress on the plants and may eventually kill some of your plants.
Soil Holding Time Return to the top	Close
The maxumin amount of time the controller should run each day. This time equals the amount of water the soil will hold.
Soil Type Return to the top	Close
The soil type is used to calculate the Point Of Run Off Time and the Soil Holding Time. The soil type is important because it is used along with the Desired Root Depth to calculate how often to irrigate.
Start Times Return to the top	Close
The number of times you need to start the controller on the day the program runs. This pervent runoff and puddling.
Station Return to the top	Close
An area in your yard where a group of heads irrigate the landscape at the same time. This is known as a number when controlled by the controller. Stations are also refered to as zones.
Variable Cylce/Days Return to the top	Close
On a Variable cycle/days the Irrigation Scheduler calculates the number of days irrigate. This is the best way to irrigate the landscape.
Water to a Cycle Return to the top	Close
The number of days in which the controller repeats each station on a program. The scheduler will show the results as; Run program ( ) on a ## day cycle. For example, a 7-day cycle is a weekly schedule that repeats once every seven days. A 2-day cycle repeats every other day.
Water to Days of Week. Return to the top	Close
This would be a regular weekly schedule. You would program your controller to run on one of the days per week. The scheduler will show the results as; Run program ( ) ## days a week.
