Productivity zones are areas of the field with different yield results for multiple years. An area with the highest yield for several seasons is considered a high productivity zone. There are also low- and moderate-productivity zones.

We identify productivity zones based on vegetation index (NDVI) data for the last four years. Using this data, our algorithms can calculate how much one part of the field is more productive than another.

Open the OneSoil web app, go to the 'Fertilizers' or 'Sowing Rate' section and select the field you want to work with. OneSoil will analyze NDVI data and define productivity zones for the field.

Vegetation index (NDVI) zones are built based on satellite images. They reflect plants' conditions at the moment the image is captured.

Open the OneSoil web app, go to the 'Fertilizers' section, select 'Nitrogen', and select the field you want to work with. The app will build three zones in the field with high, moderate, and low vegetation indices using the latest satellite image.

We separate the field into 3 zones of almost equal size because the algorithm can't define threshold values for vegetation index on the field. Values currently can't be manually added.

No, you can't change the number of zones right now.

No, zone boundaries can't be changed right now.
