Click on the triangle or enter values for percent sand and percent
clay and click on [Calculate] to obtain the soil properties for the
respective sand and clay.
is the water content at a matric potential of -1,500 kPa (-15
bars). It roughly corresponds to the lower limit of the Available Water.
This value is expressed in (units³ water/units³ soil).
is the water content at the upper limit of the Available Water or
drained upper limit. It roughly corresponds to a matric potential of -30
kPa (-0.3 bars) in most soils and to -10 kPa (-0.1
bars) in sandy soils. This value is expressed in (units³ water /
units³ soil).
As of Feb 18, 1997 this WWW page is now a standalone
application. Since the calculator no longer needs to communicate with our
server, you now get immediate calculation results and you don't need to be
connected to the network.
To download this utility to your own computer do the following.
Create a directory on your hard disk (I.e. C:\grphtext).
