RMA guides the user of the system of irrigation management from the very beginning. The user will learn how the soil works, what are the needs of the crop and how evaporation works. Thereby the user understands why the sensor produces certain data. That understanding is needed to interpret the information on the right way. Also, the customer receives in the course of the growing season more and more understanding of how soil and crop behave at a certain moisture content or after precipitation. That leads to an ever more accurate irrigation planning.
