Setting Your Warnings
Warnings are property and zone-specific settings for Very Low, Low, High and
Very High thresholds for Moisture, EC and Temperature that essentially
target the desired conditions and indicate variance from them
POGO Turf Pro allows you to set warnings specific to each zone, or zones
within other zones when unique attributes are present (e.g. Tiered Green)
The default settings in the app are generalized over thousands of properties
to get you close to the average setting. These should be adjusted to fit your
particular conditions and desires
The best way to identify your optimal moisture and salinity conditions is to
conduct a POGO Turf Pro Turf/Soil lab analysis which is unique in identifying
these variables (contact us at support@pogoturfpro.com for lab kits)
Without a lab test, setting the optimal ranges requires some time. Generally,
within 30-60 days of using the POGO routinely, you will have a good
understanding of where your values should be
It is highly advised that you do NOT compare POGO readings with any
other technology due to POGO's unique and unmatched sensor qualities as
explained earlier. Set your warning values using the POGO
