WHAT DO TRELLIS WIRELESS SENSOR STATIONS MEASURE?
Our sensor stations measure soil moisture tension or how hard the plant has to work to extract the water it needs from the soil. Soil moisture tension is a negative pressure value, measured in kiloPascals (kPa). The more negative the number, the harder it is to get water, which causes stress on the plant.
HOW DOES THE SENSOR MEASURE SOIL MOISTURE?
Each sensor station contains two Irrometer Watermark soil moisture sensors, which have been used and trusted by growers for nearly 40 years. They electronically read the amount of moisture the crop absorbs through a special mix of precisely composed materials.
WILL I HAVE ANY WIRES IN THE FIELD?
HOW ARE THE SENSOR STATIONS POWERED?
Each sensor station uses 2-AA lithium batteries, which are included with purchase and available at most supermarkets, should they need to be replaced.
HOW LONG DO THE BATTERIES LAST?
No one likes replacing batteries, so we designed the system to last approximately 2-years on 2-AA lithium batteries. We will notify you when any your batteries are getting low and need to be replaced.
HOW OFTEN DOES THE SENSOR STATION MEASURE SOIL MOISTURE?
WHAT DOES THE SENSOR STATION MEASURE BESIDES SOIL MOISTURE?
Trellis’ sensor stations also measure soil temperature at a depth of 2” below the surface.
HOW DO I KNOW HOW MANY SENSOR STATIONS I NEED & WHERE TO PLACE THEM IN THE FIELD?
Trellis recommends using 1 or 2 sensor stations per soil type per irrigation zone. You can use the NRCS Web Soil Survey to determine how many soil types you have in a given field (We're also happy to help!). As a general rule of thumb, growers usually use 2 or 3 sensor stations per center pivot irrigation system.
