Why 0% soil moisture & not scheduled?


#1

I have a Flex Lawn schedule set up with mentioned lawn zone. It has depleted soil moisture to 0%. Allowed (default) depletion is 50%. This does t seem logical. What am I missing???

I see many of my zones soil moisture going way below what I thought I understood to be allowed depreciation. I’m continually having to engage manual watering to bring (Fill) zone back up to 100%. What don’t I understand about FlexSchedules?

@miketeel

What is the controller name and zone in question?

Thanks!

Rachio 16-1 Guest Front Lawn. It’s now at 110% cause I ran it manually.

However look at any of the 4 Rachio controllers and you will find several zones that are below 20%.

@miketeel I think there might be a little confusion. 0% is actually not fully depleted, that would be a permanent wilting point. On the chart 0% means you hit the bottom of your managed allowed depletion which is just 50%.

MAD is the maximum amount of Plant Available Water (PAW) allowed to be removed from the soil before irrigation refill occurs.
For most landscape purposes, 50% MAD represents a reasonable overall value.
For sensitive, shallow rooted plants, or heavy compacted soils, a smaller depletion should be considered (30-50% MAD). For stress-tolerant plants, deep root zones or lighter soils, a larger depletion can be used (50-70% MAD)

This chart shows that before you hit 0% of your MAD we automatically irrigate.

I did notice one thing:

  • You have quiet a few controllers all running flex daily schedules. IMHO I’d try to get one of these dialed in with appropriate settings, then if happy apply to other controllers. I know its hard enough trying to get one controller, even one zone working properly if things aren’t just “working”

Hope this helps.

Dear lord I hope that UI changes. It has to be one of the least intuitive in the app. :no_mouth:


#6

Then why there no scheduled watering and I had to manually fill up?


#7

I agree, the interface is very difficult to understand and could spell the failure of Rachio if tt isn’t fixed.


#8

Looking at your next flex daily schedule for Flex Lawn watering it does show on the dashboard and in the simulator for 6/6. I can’t speak to what you previously viewed.

I had the same question when I was new to Rachio, but now that I understand it makes perfect sense. Many people have had this question, and if I had not asked, like you did, I think I would never have understood this. Perhaps Rachio needs to put something up front in big bold letters so that is the first thing that is understood when first installing a Rachio controller.

I agree, there needs to be a better description of the MAD. Even I who have a degree in horticulture and know about plant water depletion get confused with this terminology. Each year I have to remind myself that the percentage is not the percentage of water in the soil. Perhaps it should be called - percentage of water removed from the soil before the next irrigation cycle. I realize that’s a mouthful, but certainly describes it better for most folks.
