Irrigation management starts with an inventory of the plots and the locations. In doing so RMA looks for the right spots to install the soil moisture sensors. These sensors measure the amount of soil moisture in the different layers of soil. On the plot also a weather pole is installed which measures the actual data of temperature and precipitation.
This is followed by the tuning of the system. The amount of moisture that the soil can contain varies by plot. It is, among other things, depending on the type of soil, the organic-matter content and the infiltration depth. The maximum amount of soil moisture is often clear, thanks to the measurements. The setting of the lower limit demands more knowledge and understanding. That lower limit determines when the crop gets moisture deficit and so determines the moment when the water administration should start. By carefully following the intensive research and measurements at the beginning of the growing season, RMA can quickly set the correct limit values.
The measurements of the soil moisture sensors and the weather poles go through a gsm connection to a central database of RMA. Specific software converts the data into a user-friendly image. The customer can view the image on his computer. The experience is that the customers after getting instructions have no trouble to interpret the data into the right conclusions.
