This article will walk through how to use Nutrient Rx to calculate fertilizer applications based on soil or yield results.
To start ✅
Navigate to Precision | Nutrient Rx
1. Farm and Season Selection
Select a farm and season where soil / yield data is located
Choose the layer that will be used
Select one season
2. Enter the target year, field, crop, and yield layers
Zone: uses zoned yield maps from prior years (it will average if multiple years are chosen)
Mean: Uses field average from yield maps for entire field
Flat: Uses entered yield goal for entire field
3. Product and Formula Selection:
The group menu allows for Rxs to be categorized and sorted as desired
The group an Rx belongs to is displayed under the group column
Enter info for Min/Max, Split Box, >0:
Split Box Checked:
If the recommendation is greater than the max, the remainder of the product will be put into the next year/season. Separate quantities with a comma in the Max box to be credited as a percentage in subsequent years.
Split Box Unchecked:
If the recommendation is greater than the max it will re-adjust the quantity to the max
The >0 box only affects 0.
If the box is checked, anything between the set min and 0 will be 0.
Click the pencil to make changes, or view the equation.
If edits are made to the formula, hitting save will do it just for this instance
Credit: Total amount of starter credit used to compensate for product previously applied
Note: Contact your precision agronomy manager for password information to make edits to formulas
Click the planning box if this is a trial run
If the planning box is left unchecked, the Rx is generated in Field Viewer, and can be selected for reporting in Precision | Reports
The default pixel size (resolution) is 20m -- this can be changed as needed
Split by Steps: lets you split prescriptions into steps 1, 2, 3 rather than years
Process by Zone: Click if needing to zone multiple years of yield maps
Generates attribute table and summary of prescriptions
