Irrigation Module Questions

[jmed999]

I have a few questions regarding the Irrigation module.

 

-How do I know if I live on the coastal plains or interior plains?

 

-The water applied per cycle is ~0.50" which sets my allowable depletion to 0.2". Does this mean when the Irrigation requirement is 0.2" or more, my irrigation system will run?

 

-I have the following program...

 

If
       Time is Sunrise -  4 hours 
   And Module 'Climate' Irrigation Requirement > 0.5 inches
   And Module 'Climate' Temperature > 34 °F

Then
       Run Program 'Sprinkler Run 3' (Then Path)

Else
  - No Actions - (To add one, press 'Action')

 

If this program calls for the irrigation system to run when the irrigation requirement is >0.50" then how does the allowable depletion come into play?

 

Thanks! I'm trying to understand this so I can get it going smoothly.

Does the allowable deletion = 0.2" mean that when the irrigation requirement is 0.5" thus making my irrigation system run, that 0.5" of water will only subtract off 0.2" from the irrigation requirement?

 

Will the irrigation system run daily until the irrigation requirement is below 0.5"?

 

Thanks in advance!

Yes to both questions.

 

Your program will trigger when 0.5" is required, but only 0.2" will be subtracted since that is how much the soil absorbs according to the absorption factor you set. After your program runs, the irrigation requirement will be 0.3". The utility of having an absorption factor is that it'll correct calculate the soil absorption from rainfall.

 

If that's too much calculating, just set absorption to 100%.

Thanks for the reply!

 

-Lets say I get 1.0" of rain today. How much will be subtracted from my irrigation requirement? 1.0"?, 0.4"?, 0.2"?

 

-If my irrigation system runs and delivers 0.5" but only 0.2" is subtracted off the irrigation requirement, what happens to the other 0.3"? Is it assumed to runoff, evaporate or what?

 

-Is there a way to utilize 2 irrigation modules, one for the front and one for the back yard? My front yard is about 20% absorption and the back is about 80%. Is there a way to split these up? ie. have the front set to one absorption rate, irrigation rate, irrigation zones, etc. and the back on another?

 

 

Thanks again!

Your absorption factor is set at 40% (0.5in -> 0.2 allowable depletion), so 1 inch of rain will subtract 0.4" from your Irrigation Requirement

 

-If my irrigation system runs and delivers 0.5" but only 0.2" is subtracted off the irrigation requirement, what happens to the other 0.3"? Is it assumed to runoff, evaporate or what?

 

I believe it is runoff

Is there a way to split these up? ie. have the front set to one absorption rate, irrigation rate, irrigation zones, etc. and the back on another?

 

I don't believe there is a way to setup different absorption zones. You'll have to compensate by irrigating longer or setting up a program to irrigate 1 zone more frequently. This was my setup for different irrigation requirements (post 3):
