  • Page 4: Theory Of Function

    1 THEORY OF FUNCTION Irrigation is one of the most important operation in agriculture. With proper irrigation the quality and quantity of crops can be significantly enhanced. Correct irrigation is not a simple process: the quantity of water must be suffi- cient for crops, and if not, photosynthesis and overall growth is impeded.

  • Page 5: General Description

    2 GENERAL DESCRIPTION The Fertigation Controller is a micro-processor-based system used in fertiliza- tion and irrigation control for greenhouses or open fields with powerful, flex- ible programming features. The main function of the Fertigation Controller is supplying and controlling the necessary water and fertilizers for crops according to several parameters such as acidity, conductivity and received solar radiation.

  • Page 6: Functional Description

    3 FUNCTION DESCRIPTION In this chapter the main functions of the Fertigation Controller are presented. For a better understanding see the typical installation schemes utilized for irrigation and fertilization presented in the Installation Block Diagram, Appendix 5. 3.1 IRRIGATION CONTROL The Fertigation Controller can control 8 to 32 sectors (one valve per sector) for each of the ten irrigation programs: - 1 to 32 valves (sectors) can be selected specifying the sector’s number and...
  • Page 7 - The accumulated solar radiation starting level value is used as a threshold value for the accumulated solar radiation. When the accumulated solar radiation value exceeds this threshold level the irrigation program is started (or it is brought in READY state if there are other programs currently run- ning at that moment).
  • Page 8 SOLAR RADIATION FACTOR: - This option can be set using panel S 42 (CORRECTIONS). This factor affects the irrigation time or volume extension in accordance with the set value of the solar radiation sensor level and solar radiation accumulation. The solar radiation accumulation extension setting and current value is displayed on panel C 06 (SOLAR RAD IRRIG).

    sectors using one of the following ways: - Manually - Every day at specified hour - Automatically when the accumulations counter value overflows 3.2 CONDUCTIVITY CONTROL Conductivity control is used to control the fertilization and a reading can be obtained with one to three conductivity sensors, one to two for fertilization control and one for water supply conductivity control.

  • Page 10: Fertilization Control

    3.3 FERTILIZATION CONTROL Fertigation Controller can use up to 4 fertilizer tanks. Each irrigation program can specify the percentage for each type of fertilizer. These values can be set using panel S 39 (SET FERTILIZERS). The fertilization is done in accordance with the conductivity control. Each irriga- tion program has a specified conductivity target value (conductivity reference value which is set using panel S 41 (COND CONTROL);...

All pH averages can be deleted manually or at specified time of day using panel S 61 (ERASE STATISTICS). 3.5 PID CONTROL A simplified schematic of the control (pH and EC): EC and pH control is performed using an automatic regulated system with PID controller (Proportional, Integral and Derivative).

The amount of neutral solution added is relative to the opening of the valve, which is directly proportional to the magnitude of difference between the mixing tank pH and the set point. Control of pH implies a complex adjustment.

    can compensate for changes in the process variable (measurement) and is par- ticularly good for slowly moving processes. When a change occurs in the pro- cess the derivative action causes the controller gain to move the “wrong” way until the measurement gets near the set point. 3.6 AGITATOR CONTROL Each of the 4 fertilizer tanks may have an agitator.
