Root Zone (RZ) Effective root depth which is generally considered the top 50% of the maximum root depth. Typical Root Zone is 4-6 inches for annual flowers and ground covers, 4-8 inches for cool season turf, 6-12 inches for shrubs and warm season turf, and 12-24 inches for trees.
Each type of plant is assigned a specific root zone depth, for warm climate lawns this is 6 inches. Here too, you can precisely determine the root zone depth in the advanced settings. Effect: A greater root zone depth leads to longer watering intervals and longer running times.
Decreasing the precipitation rate (Inches/Hour) will increase the amount of time. zone runs on an irrigation day. Increasing the root depth will increase the amount of time a zone runs on an irrigation day AND lengthen the watering day interval (days between watering)
20 sie 2020 · Anyone have an Orbit b-hyve faucet timer and trust the 'calibrated' flow rates? I'm only getting around 4.5 GPM whereas the way my system is currently set up I should get somewhere near 9 GPM.
Most root systems for all grass types can grow much deeper than the topsoil found in typical residential lawns. By watering deeply, core aerating, and applying bio-stimulants on a regular basis grass roots can be encouraged to put on deeper and wider growth without the aid of excess phosphorus.
7 lip 2020 · The only issue I ran into was an occasional "zone fault" error. I have one zone that uses a 24VAC contactor that starts a pump rather than a normal solenoid valve. The documentation states to test the solenoid resistance, and that a good one should measure between 20 and 60 ohms.
I'll bet the turf has very shallow roots and is very dependent on the constant watering, zero drought tolerance, even though it is an area that would benefit from training the grass to grow long roots.
