The FullStop Wetting Front Detector was designed to be a simple, inexpensive and robust device that gives a yes/no response to whether a wetting front has reached a particular depth. When searching for simplicity and low cost, tradeoffs need to be made with sensitivity; in the case of FullStop the decision was made to detect a 2 kPa strength wetting front. From a theoretical perspective, the FullStop Wetting Front Detector is not well suited to furrow irrigation, deep placement, cracking (more)...

Using Wetting Front Detectors in Furrow Irrigation

The Wetting Front Detector (WFD) is a new tool to help measure how deeply water has penetrated into the soil after an irrigation event. The WFD also captures and stores a soil water sample, which can be analysed for its salt or nutrient content. The first commercial version of the Wetting Front Detector (WFD), called the FullStop, was released in 2004. The FullStop WFD is comprised of a (more)...
