I guess doing this would mean running a pair of wires out to each sensor and then connecting each sensor to a GPIO pin. Of course you could use wireless but than means a visible sensor (think lawn mower) to find the sensor to change the batteries once every couple of years.
Whilst I love the idea of soil moisture sensors to regulate watering, this would be a heck of a retrofit for some installations. Nice though.
