Change existing crop data or application for fields
Change existing crop data or application for fields
If you have selected Change existing crop data or applications for fields in Step 1, then follow these steps to complete the task.
STEP 2: SELECT THE FIELDS YOU'D LIKE TO MODIFY CROPPING DATA FOR
•Choose the fields to include in this operation by selecting field names in the left (unselected) pane of the dual select list and using the arrows to move them to the right (selected) pane. You can limit the fields shown by group or subfarm by using the dropdowns above the field selection area.
•Click Next to go to the next step.
STEP 3: SPECIFY WHAT TO CHANGE
Selecting which years to make changes to:
The change wizard makes changes to the fields you select based on a crop sequence you specify. The wizard only changes data in years that exactly match the crop sequence you have entered. At the top of the Step 3 screen are dropdown lists for selecting crop, prior crop and two years prior crop to specify which years you want to change. For example, if you select a crop in the Crop is dropdown, and leave the prior and two years prior crops as Any, then the change wizard will change data in years you have chosen which match that crop. If you set all three crop dropdowns to Any, then every year in the fields and year range you have specified will get changed.
Before you actually make changes, you can check to see which fields and years will be affected by clicking the button labeled Check for this crop sequence in the fields and years selected.
Choosing what data to change: Cropping data
If you have chosen to change cropping data in Step 2, then the lower part of the screen for Step 3 will show a set of dropdown lists for cropping data. Initially, these will all be set to No change indicating no changes will be made. Set only those items you wish to change.
•Crop: This dropdown contains the list of selected crops specified on the farm screen. Selecting a crop will replace the crop you have chosen in the Crop is dropdown list when the crop sequence criteria are met.
•Prior crops: These dropdowns contain the list of selected crops specified on the farm screen. Selecting a prior crops will add to your crop search sequence criteria. When you select an alfalfa or corn crop, a pop-up dialog will be displayed that will allow you to select multiple crops of the same type.
•Yield Goal: The options in this dropdown depend on the old crop (the one you are changing from, selected in the Crop is dropdown) and the new crop (the one you are changing to, selected in the Crop dropdown). If the new crop is specified, the options will match those for the new crop. If the old crop is specified, then the options will match those for the old crop. This allows for the just the yield goal to be changed for many fields. If both are specified then the the options will match those for the new crop. If neither are specified, then the dropdown will be blank.
•Tillage: The tillage options in this dropdown depend on the old and new crop as explained in the Yield Goal section above.
•Soil test date: Because soil test dates may be different for each field, you cannot pick specific soil test dates to change to. If you wish to make changes, select from either Most recent in year range or Most recent available.
•Irrigation: Pick Irrigated or Not Irrigated to set all cropping years which match the selected crop sequence.
•Legume Credit Data: This control is disabled unless the prior crop is set to one which gives a legume credit. Adjust Stand density and Stand height for all cropping years which match the selected crop sequence.
•Season notes: Choose to either add to or replace current season notes with the text you have typed in. Selecting Replace existing without adding new text will clear existing season notes.
Choosing what data to change: Application data
If you have chosen to change nutrient application data in Step 2, you can search for specific criteria using the dropdown menus at the top of the screen.
The lower part of Step 3 will show a table for specifying applications to add to existing cropping years which match the selected crop sequence. There are three choices: Add existing apps, Delete existing apps first or Edit existing app spread method/rate.
To add nutrient applications, the user has two different options. One option is to add them each individually. Another option is to add a Nutrient System. For more information on the Nutrient System Editor please refer to the Nutrient System Editor section.
Option 1: Adding Applications Individually
Then use the and buttons to set up the applications needed.

•Click the Next button to move to the next step.
STEP 4: CONFIRM SETUP
•Confirm setup: A last check on the list of fields to change before changes are made.
