Re: Gypsum Blocks : with Aquamiser - more info required

[jjohnsto@mail.deltanet.com]

Gypsum blocks breakdown due to soil chemistry, and dissolution. Soil pH is
more a concern with these sensors. They are good for 1-3 years. I suggest
you consider a Virrib sensor for low cost soil moisture information. The
main disadvantage of Virrib is that you have to dig a hole to install them.
If you have already accepted that reality then this is the best low cost
sensor available for a wide range of soil conditions.
