VARIABLE RATE IRRIGATION
Variable Rate Irrigation (VRI) allows you to customize water application based on topography information, soil data maps, yield data, and other user-defined information. Based on your VRI Prescription, you’re applying water only where it needs to be. So, you are not applying water to unnecessary areas in your field, such as: ditches, canals, buildings, and boggy areas.
VRI is precision agriculture made easy. You can wirelessly upload your VRI Prescription to your center pivot with AgSense® remote communication products. And because you can wirelessly upload your prescription, you can quickly make changes as your water application needs change in the field. Don't use remote communication? You can also hard-wire upload your prescriptions directly to your computerized control panel.
With VRI, you can:
- Make all areas in your field more profitable
- Reduce runoff, which can help your soil's health and the environment
- Increase water and chemical application efficiency
- RELAX — you know that your precious water resources are being used wisely!
How It Works
Begin With A Base Layer
Before any VRI prescription is entered into a control device, we begin with a base layer of data. The most common type of data that we use at Tri-State is EM data, or Electromagnetic data. EM measures the conductivity and magnetic susceptibility of the ground. Other forms of base data that is used fro VRI is yield map data and ssurgo data, as shown below.
Rx Creation
After the base layer of data has been gathered, it is uploaded to Virtual Optimizer platform and the base prescription is made. Every prescription is fully customizable to fit the needs of each field.
