VRS: Including MYYA into Decision Zones
Multi-Year Yield analysis is used and created to classify multiple years of yield datasets into categories of yield ranges based on normalized yield. MYYA layers are used to create decision zones in Granular Insights, enabling variable rate seeding prescriptions.

- An active Granular Insights account with access to an operation that has field boundaries.
- Multiple years of yield data (one year required, three years recommended)
- Crop added to desired fields.
There are two ways to get multi-year yield analysis layers in Granular Insights, automatically generated MYYA and manually generated MYYA.
When new yield data is uploaded and processed in your operation in Granular Insights, if the data covers at least 80% of the field , we will automatically create a new MYYA layer for the field based on this new data and any previous data. Previous MYYA layers on your operation that have been used to create decision zones will remain available on your operation.
Automatic MYYA ensures that you have quick and easy access to MYYA layers based off your most recent data. Learn more about Automatic MYYA
You can customize the yield data used in your MYYA layer by manually creating a MYYA layer. When you manually create a layer, you can choose the yield data you want to include in the layer, and you can set custom analysis parameters.
Process - Web
- Log in to Granular Insights https://us.insights.granular.ag
- Select "VRS" on the left sidebar navigation menu.
- Select "Create New Decision Zones” to create a new or edit to make modifications to an existing Decision Zones.
- Select Decision Zones button to add, edit, and delete Decision Zones (This button was previously on Activities dashboard)
- Select "Create MYYA" under MULTI-YEAR YIELD ANALYSIS section
**Currently we do not have a bulk option to create Decision Zones for multiple fields at a time.
***Options for Polygon size (Please enter a value between 0 and 10).
- Under Layer Name type in what you would like to name the Multi-Year Yield Analysis.
- Select the checkboxes next to the years you would like to include in the MYYA.
- Enter in the Analysis Parameters you would like to implement for the Multi-Year Yield Analysis.
- Below Average is a percent value compared against the average yield, below which is considered Low yield quality. The comparison is based on 100% equaling the average yield for the field. The default value is 96%, meaning that areas yielding under 96% of the average are considered Low.
- Above average is a percent compared against the average yield, above which is considered High yield quality. The default value is 104%, meaning that areas yielding over 104% of the average yield are considered High yield.
- Stability cut-off is a percent value to determine year-over-year stability of yield quality. This determines the break point at which yield results are considered Variable and not Average, Low, or High. A lower percentage value allows for more variance in the average yield, which may result in more areas classified as variable. A higher percentage value allows for more variance in the average yield, which may result in fewer classified as variable. The default value is 80%, meaning that the year-over-year quality must have a higher variance to be considered Variable.
