Why should I monitor soil moisture?
You wouldn’t play darts blindfolded, so why would you plan your irrigation the same way?
Remote water management gives the ability to measure and track soil moisture and has proven to be an incredibly important tool for irrigation scheduling. The more accurate data you have, the more confident you can be that you’re not wasting precious water.
How does it work?
Electrical resistant blocks known as “Watermarks” are buried in the soil. These sensors take regular moisture readings throughout the day and then upload the information to the Internet. This allows irrigation managers to read soil moisture in near-real-time, resulting in better remote water management of the irrigation system. It also ensures you’re hitting the mark with “when” and “how much” irrigation water to apply. Managers can then determine when to refill the soil profile to field capacity (or full point) based on the soil type and sensor reading.
What does the data mean?
Full point is that point that the soil profile has been fully wetted and drainage has ceased and the soil reservoir is storing as much water as it can hold. Full point and refill point can vary throughout the growing season depending on crop rooting depth. Each sensor depth can be assigned a different soil type.
The Watermark sensor measures soil moisture status in units of soil moisture tension also known as centibars (cb). As cb readings increase, the greater the tension, and drier the soil. In the soil moisture charts, cb readings have been converted to “percent field capacity by soil type” in order to make a quick correlation in the soil moisture status.
