DUETS
Julie: Sensors have driven precision
responses in crop production. Using
a collection of sensor readings
can prevent over-heating, overcooling,
and over-watering. The
more information the control has,
the more astute the response. More
sensors allow prioritization specific
to the plant's needs. Based on
these settings, the equipment, from
irrigation to ventilation and curtains,
responds with very tight parameters.
Sensor data is a valuable tool for
growers to evaluate production times,
crop quality and trends.
Using DLI (daily light integral)
and VPD (vapor pressure deficit)
accumulation readings allow for extra
watering on hot days. A soil sensor
allows for averaging air and soil
temperatures resulting in better set
point management. Our Seed control
can average the soil temperature into
the zone temperature, or factor soil
temperature into VPD offering a better
view of transpiration.
Growers who want more precise
control over their irrigation cycles can
also use a soil sensor for dry back,
which ensures the soil has sufficiently
dried between waterings. This can
yield hardier plants with better root
development, and even train certain
crops to require less water.
Combining irrigation and fertigation
offers a very precise, repeatable
operation. Fertigation recipes can
be tied directly to irrigation events
to provide the best conditions for
delivering nutrients. That allows
growers to adjust nutrient injection
based on live and historical EC/pH
(electrical conductivity and level of
acidity) values.
Seed, not an acronym, interfaces
with all sensors and can manage
many zones. It's also our most userfriendly
control. It has an accessible
user interface like smart phones,
but with deep functionality. What we
hear from growers who upgrade to
a Seed is, " How did I get by without
this? " The Seed app and Wadsworth.
Cloud allow access from anywhere at
any time, graphing, data collection
and multiple users. Access, more
information, and informed responses
from the controller, are all in response
to requests we've received.
Peter: Again, thank you for joining
me Julie. I enjoy presenting fellow
small business owners who operate
in our industry's supply chain to our
similarly sized greenhouse and farm
operators. It gives us all confidence
knowing small to medium sized
businesses can thrive in the greater
agricultural community.
