Fertigation Systems for Vineyards
Monitoring Irrigation Water
Monitoring irrigation water should be done regularly, to make sure that the fertigation unit is functioning correctly. There are two ways to check your fertigation program: electrical conductivity (EC) and irrigation water nutrient levels. The best way to determine if your fertilizer injector is working properly is to monitor the EC of the various fertilizer solutions. EC is a measure of the salinity (total salt level) of a solution and therefore gives an indication of the dissolved fertilizer salts. An EC meter measures the electrical charge carried by the ions that are dissolved in a solution—the more concentrated the ions, the higher the reading. By checking the EC at each step in the process, you can be sure that your injector is functioning properly.
