   * D: “EC Compensation (%)” –
   * E: “EC Compensation Adjustment (%)” -
+=====Alarms=====
+{{ :programs:fert_alarms.png?nolink&400|}}
+====Fertilizer Flow Rate Alarms====
+  * A: “Alarm on Low Tank Level” – Tick to enable alarm on Low Tank Level
+  * B: “Enable Fertilizer Flow Rate Alarm” – Tick to enable Flow Rate Alarm set on Fertilizer
+  * C: “Flow Fertilizer Rate Error (%)” – Enter percentage Flow Rate allowed to be higher than expected before alarm is triggered
+    * Note: this percentage is the inverted; meaning if the expected Flow Rate is 100L/h, & Error is set to 80%, the alarm will be triggered on 100L/h + 20% = 120L/h
+  * D: “Alarm on EC Error” – Tick this box to enable alarm on EC Error
+  * E: “Alarm on PH Error” – Tick this box to enable alarm on PH Error
+  * F: “Fertilizer Alarm Duration Threshold (sec)” – The duration of time allowed for the Fertilizer programs values to be higher than margins allow before the alarm is triggered
+  * G: “Uncontrolled Alarm Amount (L)” – Max Volume of Fertilizer allowed to pass during one dose before alarm is triggered
+    * This alarm is for when the Fert Valve does not close (overdosing)
+    * Or when there is a leak
+====Fertilizer Pump Alarms====
+  * H: “Fert Pump Start Delay (sec)” – Enter the pump start delay here
+  * I: “Fert Pump Alarm Sensor” – Select the relevant sensor from the dropdown list
+  * J: “Fert Pump Alarm Min” – Enter the min value allowed for sensor selected
+  * K: “Fert Pump Alarm Max” – Enter the max value allowed for sensor selected
+=====Output Control=====
+{{ :programs:output_control.png?nolink&400|}}
+  * A: “Max Catchup (%)” –
+  * B: “Output Rate Control”
+    *  	“Always On” – used during batching, keeps the dosing valve open
+    *  	“Analog VSD Output” –
+    *  	“Duty Cycle” – used during proportional dosing, opens & closed the dosing valves based on values entered in C – E
+    *  	“Pulse Frequency” –
+    *  	“On/Off Delay” – used during proportional dosing, opens & closed the dosing valves based on values entered in C - E
+  * C: “Min Injector Off Delay (sec)” –
+  * D: “Min Injector On Delay (sec)” –
+  * E: “Control Cycle Duration (sec)” –
+======Adding Fertilizer to Valve Program======
+=====Adding a Fertilizer Program to a Step=====
+Each “Step” has provision to add Fert Programs.
+{{ :programs:fert_to_step.png?nolink&400 |}}
+  * A: To add a Fertilizer program to the Valve Program, click on the “+”
+{{ :programs:fert_step_details.png?nolink&400 |}}
+  * As seen above, you can now enter the following specifications:
+    * "Liters" - if dosing according to a batching method
+    * "L/m3" - if dosing according to a proportional method
+    * "EC" - if dosing to maintain a certain EC
+    * "Pre-Delay" - duration of time that must pass from start of irrigation until fert program starts
+    * "Post-Delay" - duration of time that the fert program must stop before the irrigation program stops
