Soil Moisture Sensors

Soil moisture content is highly variable. Accuracy from a single site isn't enough to run an experiment. To make good soil water content measurements, you need research quality soil moisture probes and you need a lot of them.

Decagon's soil moisture sensors are research grade probes at a price that lets you completely characterise your site.

Plug-and-log with the Em50 line of data loggers or integrate into other logger systems (including Campbell Scientific).
