Across the Fenceline soil water information website.
Use the Main Menu on the left hand side to explore
the site, pick a farm from the Map below for detailed information on it,
or select from the Quick Links menu to jump straight to the data pages.
From 2003 to 2005, a site was also monitored
at Binalong.

05 November 2008 - New data online
Soil water sensors are now operational at the Kia-Ora
pasture site. Limited data is available as yet.
In addition, all soil water sensors have now been reinstated at the
Cusacks and Garangula sites.
Soil water sensors have been removed from the Lowlynn site
for repair and will be reinstalled as soon as possible, but probably
not before early in the new year. 05 August 2008 - New Look for website
The website is currently under migration to a new format. This
page has already been changed and shows some of the new features
such as the 'Quick Links' menu. The upgraded website will have an
emphasis on easy access to information, as well as a few more
visuals.
Changes will take place gradually, a few pages as a time, but will
be complete before the end of the year.
Feedback
on the changes is very welcome, particularly if you think there are
any backward steps. 27 July 2008 -
Data corrections
For some time it has been obvious
that the water content data contained a seasonal oscillation caused
by the response of the water content sensors to temperature changes.
A simple and robust method for removing this effect has now been
found, and it has been removed from all data. The method is not
perfect, and there are still some small anomalies. Nevertheless, the
water contents and data derived from them (such as storage and
readily available water) are now much easier to interpret. To see
the effect of removing the seasonal oscillation,

At the
same time, estimates of lower limits, used to calculate readily
available water, have been revised and different values used for
each paddock. Commentary 27 July 2008
The rainfall from the last couple of
months has finally started to accumulate at 80 cm. This is clearer
to see now that the temperature oscillation has been removed from
the data. At Traralgon,
for example, the amount of
available water in the soil is still slightly below that at the same
time last year, and well below 2005, but similar to 2003 and 2004.
With these minimal available water levels, crop performance will be dependent
on continuing rainfall. |
