He said the probe helps understand soil moisture from the perspective of the crop’s root system. “You need to know how much moisture you have, but just as important, you need to know if it’s at the bottom of the root zone or shallow near the surface. ...
The water requirements of crops are dependent on evapotranspiration (ET), soil chemistry, and the crop’s maximum allowable depletion (MAD). Direct measurements of root zone soil moisture, water application along with published ET values and soil textures, can be used in a soil water balance model that can significantly optimize irrigation ...
