You can estimate the extent of the living root zone of a plant and visualize
the actual depth of an irrigation or rainfall event.
Since the Diviner 2000 display unit automatically displays the ten most
recent soil moisture readings for the one site, you can easily identify soil
moisture trends. However, data recorded with the Diviner 2000 display unit
can be downloaded to your PC for backup farm record maintenance.
Data use
The Diviner 2000 display unit, the probe, the installed access tubes and the
Diviner 2000 Utilities software combine to give you meaningful data on
soil moisture and:
•
daily crop water use
•
extraction patterns from different layers of a soil profile
•
depth and distribution of the root zone
•
depth, distribution and effectiveness of the 'wetting front' after an
irrigation or rainfall event
•
changes in soil texture and/or structure
•
use of crop water use in stressed and/or non-stressed crops
•
onset of crop water stress
•
crop water use changes, e.g. the effects of different crops, varieties,
ages, canopy sizes, fruit loads, irrigation system performances, soil
types, topographical exposure, disease incidents, cultural
management practices, soil salinity changes, soil structural
problems, weather conditions and many other factors
•
crop water use under water logged conditions
•
occurrence and impact of water tables on the soil profile and the
crops root zone
•
changes of the shape of the 'wetting onion' in drip irrigation
•
site specific budgets for optimal crop productivity and irrigation
efficiency. With these budgets you can predict the next irrigation
date and the necessary amount of irrigation to refill the profile.
Some of this information requires expert advice. This user guide will get
you started.
Review the Diviner 2000 video, which came as part of your package. It
shows the portability of the display unit and probe and illustrates the 'swipe
and go' technique used for collecting data.
Installation/calibration recommendations
Sentek
recommends that trained distributors or agronomists set up and
configure your Diviner 2000 system. Their experience and training should
