LongStop

Product Information

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 soils or where soil disturbance must be minimized. The LongStop Wetting Front Detector has been specifically designed for the above applications. Working prototypes have been built and have undergone limited field testing in sandy soils. This pilot study evaluates the performance of the LongStop under a furrow irrigated cotton crop on a cracking grey clay soil.
