Yield variation between different tools
If you’ve uploaded the same data into multiple farm software programs, you may notice variations in the yield figures displayed. These variations may be present between your monitor display and software programs, across different farm software programs from different companies, and even between different Corteva digital tools.
It’s important to understand that variation in yield does not necessarily mean that the data is wrong or that the software is broken. If the difference in yield displayed is less than 10% between different digital tools, this variation is expected due to a few differences among digital tools:
- Data cleaning rules. Each program has unique protocols to clean data as it is imported. These protocols are developed over the years to account for specific use cases. Some software programs clean or remove more data points than others.
- Selected area used in yield calculation. Yield is typically displayed in bushels per acre. In order to get area in terms of acres, some programs use the field boundary area while others use the area covered by the combine during harvest. In most cases, there is very little difference between the two, but in other cases, this may cause variation in the yield figures displayed.
- Granularity of data used in yield calculation. Once the data is imported into a software, typically, each software aggregates the data to make it easier to visualize or analyze. Software programs differ in the degree to which they aggregate the data. These differences are often driven by the different use cases that the software was designed to support. For example, AgStudio handles data as a series of points to maximize the flexibility in how the data is used for many different kinds of specific agronomic work flows. Granular Insights, on the other hand, handles data as a raster, or a collection of points, to make it easier to quickly display various map layers.
These three differences are the most common drivers in yield variation between different software programs. However, it is important to note that there may be other differences unique to certain software and monitors. These differences are simply the result of designing digital tools for different use cases.
As for the Corteva digital tools, our team is working hard to ensure that your data is displayed accurately and consistently so it is most useful to you. If you observe differences in yield greater than 10% between your tools or your data doesn’t look quite right for any other reason, we are here to help.
