Using NDVI charts and uploading data from the fields, you can forecast the ripening date, determine the order of field harvesting, and analyze yield.
How to forecast the harvest date
If you have multiple fields with the same crop but different planting dates, compare the NDVI charts in the web app under the 'Status' section. Select the most mature field and compare it with the less mature ones. This will help predict the approximate harvest date for the latter.
How to determine the order of harvesting
First, we need to find which field to start harvesting from. Monitor the average NDVI in the mobile or web app. To view the average NDVI, open the 'Fields' tab, and at the top of the screen, set the fill and label criteria to 'Average NDVI.' Compare the values. The closer the field is to harvest, the lower the NDVI on it is.
Next, we need to understand from which part of the field to start harvesting. To do this, check the NDVI index in different parts of the field. Start harvesting from the side of the field where NDVI is lower.
How to analyze yield
If you have a combine with a yield monitoring system, upload the file from it to OneSoil. Visualization will help you understand the speed at which the machinery was moving, whether it left any gaps, and how much grain was harvested in different parts of the field.
Click the 'Upload Data' button and select the type of data to upload: Yield map. To upload, drag the relevant file into the browser window or select it on your computer by clicking the 'Select files' button.
Match the attributes. It's important to match three of them: yield data, units of measurement, and timestamp (the time when the yield point is recorded).
The uploaded file can be viewed in the 'Data' section.
OneSoil Pro users can also compare the yield map with productivity zones or NDVI to assess the effectiveness of variable-rate application. We explain how it works in this article.
