- Moisture (VWC)
- Site-calibrated; measure field capacity and dry-down
- Salinity tolerance
- Generally good if this is Cynodon turf
- Drought tolerance
- Good survival once established
Optimal root measurement depth
3–6 in
Warm-season turf roots concentrate here at fairway and sports heights of cut. Typical guidance; confirm with a soil probe on site.
Calibrate sensors in the actual root zone; account for mowing, rooting depth, seasonal growth and drainage before adjusting irrigation.
