A METHOD FOR DETERMINING THE MAGNITUDE OF AN IRRIGATION EVENT IN A SECTION OF SOIL, AND RELATED SYSTEMS

摘要

A method for determining an amount of moisture that has entered a section of soil via irrigation, includes sensing at a first moment in time a total amount of moisture in a sub-section of the section of soil, and in response to the amount sensed at the first moment in time, determining a total amount of moisture. Sensing at a second, subsequent moment in time a total amount of moisture in a sub-section of the section of soil, and in response to the amount sensed at the second moment in time, determining a total amount of moisture. Comparing the totals by subtracting and it may also include determining an amount of moisture that has left the section of soil during the period between the first and second moments in time.
