Tips From Tech: Fall Granular Application
Hard to imagine but before we know it harvest will be over and fall granular fertilizer application will be in full swing. There are several things to keep in mind when beginning to apply that I will outline in this blog.
You will want to create a new season in the display as the 2016 crop is now complete. Creating a “2017 Crop” season before applying will keep your application data tied with the rest of the operations for the 2017 crop year. After you have exported your harvest data and successfully loaded data into SMS on the computer, you can delete the 2016 season from the display. This prevents the display memory from filling up.
Make sure all the products and product mixes are entered in the display. Verify they are all in the correct units. Having correct units is very important especially when using variable rate prescriptions. The other thing that needs to be selected properly when loading the configuration is the controlling product. For example, if you are applying DAP, you can select it to control in lbs of total DAP, lbs of Nitrogen, or lbs of Phosphorus. If just running on a straight target rate, this is up to the user. If you are running variable rate prescriptions, the controlling product must be the same as what the prescription is written for or product will be applied at an incorrect rate.
Each product will need to be calibrated. There are two calibration processes that need to be completed. The first one to be completed is a static calibration that is done just sitting still. The second one is an in-field calibration that will fine tune the static calibration. This is done while applying in the field. A complete description of the calibrations can be found in the display operator manual.
