The Irrigation operation is normally used in sugar and alcohol culture applications. In the vicinity of sugarcane plantations, it is common to find reservoirs of vinasse – one of the liquid by-products of the fractional distillation of fermented sugarcane juice, which is highly rich in nutrients. Next to these reservoirs, there are large-caliber hose reels, hundreds of meters long. The hoses are completely stretched out in the field with the help of tractors, so that the application of vinasse can be triggered at a high flow rate and with great lateral reach, while the hose is automatically collected by the reel mechanics, filling a large area of the crop with the liquid fertilizer.
The system IsoView assists the operator in various phases of the Irrigation operation. First, in the process of stretching the hose, informing through visual and sound alerts when the distance parameters referring to the length of the hose are reached, avoiding damage and breakage. And through the various Types of Guide available, allows the producer a uniform application, without gaps and overlaps, using the configuration of the width of the Implement as the lateral reach of the hose flow.
To set up Irrigation operation on the system IsoView, follow the steps described below.
1) Configure Implement Width
The width of Implement will be used to fill in the Trail carried out during irrigation application.
2) Configure Hose parameters
The irrigation settings button will be available on the navigation screen 
. By pressing the button, the left side buttons bar will assume the configuration shown in the figure below.
The Max Distance setting button 
allows configuring the total length of the hose, with values between 1.000 e 2500.000 meters. The Max Distance setting screen is shown in the following image.
It is also possible to configure a distance to start sounding the visual and audible alert during the process of stretching the hose, using the Alert configure button. 
. By pressing the button, the Alert configuration screen will be displayed, as shown in the following figure..
3) reset the odometer
When the irrigation settings button is pressed, the Information Board displays the Odometer value, which is incremented as the tractor travels. To reset its value and start the procedure to stretch the hose, the odometer reset button must be pressed 
.
4) Create a Guide
Before starting the irrigation operation, the user can perform the procedure described in Create a Guide, to guide the process of filling in the crop area.
5) Start Irrigation
To start the irrigation operation, press the irrigation trigger button. 
. so much the Information Board how much the Baseboard of the navigation screen are modified as shown in the image below. The trail is also activated, demarcating the area that will be applied when the hose is collected applying the input.
While the tractor moves stretching the hose, the values of the Information Board and the graph of Baseboard are updated.
- A Distance to alert is decremented from the value configured in the Alert until it is zeroed, when its displayed value changes to ACHIEVED!.
- The distance value Limit is decremented starting from the value configured in the Maximum Distance of the hose until it is reset to zero, when its displayed value changes to ACHIEVED!.
- O Odometer is incremented according to the distance the tractor travels.
- The ruler marker present in the footer graphic moves to the right, while the area to the left of the marker is filled with a color dependent on the distance traveled to the Alert parameter since the trigger irrigation button was pressed
![]()
.
- Green: Up to half the Alert distance.
- Yellow: Between half and full value of Alert distance.
- Red (flashing): From the total value of the Alert distance. Intermittent beep is also triggered..
When the total distance of the hose is reached, the ruler is completely filled in red in a flashing way, and the beep is activated constantly, warning that the hose may break from this moment on.
