With CropSAT, you can see how crop biomass is changing in the field. Based on this information, you can control fertiliser or spray applications in the field according to where they are most needed and perhaps consider the reasons for differences.
If you have the right equipment (GPS, Variable Rate Spreader or Sprayer, etc.), you can make prescriptive Variable Rate maps for your fields based on the NDVI index, thus saving nitrogen fertiliser by fertilising where it is needed.
For each field, we have satellite images taken on different dates. These images are constantly updated. It is important to choose an image that is free of clouds, cloud shadows and fog.
When you select an image date from the list, you will see a preview of that image. Decide for yourself whether your outdoor photo looks good to you. It may be a good idea to zoom in a little to see the quality of the image better.
The system has automatic quality control that automatically removes cloudy images. However, sometimes inappropriate images still end up on the list, so it is important that you double-check the photo you are about to use.
“CropSAT is free for everyone to use and satellite images from all over the world are available for various dates.
Set a goal and it will be automatically implemented outdoors!
Maybe you already have a clear plan for the average rate of nitrogen you want to apply to your winter wheat field, but you still want to spread it in different ways? With CropSAT’s automatic nitrogen spreading function, all you have to do is enter your desired average rate and our algorithms will do the rest. In this video, Mattias shows how to do it.
Automatic nitrogen allocation allows you to create a variable-rate nitrogen allocation map by entering just one value – the desired average nitrogen rate in kg/ha, which you can then use with your equipment.
Generic actions:
- Log in to CropSAT.
- Click on the ‘Upload fields’ button on the left-hand side and select the current year.
- Select the field you wish to view and click on ‘View satellite images’.
- Select the date you want to view and click ‘Continue’.
- Next, select what you want to use the NDVI map for.
Automatic nitrogen allocation:
- See what differences in biomass are visible in the field and enter the desired average nitrogen rate in kg/ha based on this. Click “Continue”.
- In the window that appears, enter the amount of nitrogen in the fertiliser and this will calculate the required amount of fertiliser for the whole field.
- Enter a title and save the map in CropMAP and/or download it for use on your equipment.
Manual nitrogen distribution allows you to create your own nitrogen fertiliser distribution file for later use with your equipment.
Generic actions:
- Log in to CropSAT.
- Click on the ‘Upload fields’ button on the left-hand side and select the current year.
- Select the field you wish to view and click on ‘View satellite images’.
- Select the date you want to view and click ‘Continue’.
- Next, select what you want to use the NDVI map for.
Manual nitrogen allocation:
- If you select manual mode to map variable rate nitrogen fertilisation, you will be greeted by a range of 5 NDVI values (from minimum to maximum) found in the field.
- Review the biomass differences visible in the field and enter the desired nitrogen rate in kg/ha for each biomass zone accordingly. Click “Continue”.
- In the window that appears, enter the amount of nitrogen in the fertiliser and this will calculate the required amount of fertiliser for the whole field.
- Enter a title and save the map in CropMAP and/or download it for use on your equipment.
Manual nitrogen distribution allows you to create your own nitrogen fertiliser distribution file for later use with your equipment.
Generic actions:
- Log in to CropSAT.
- Click on the ‘Upload fields’ button on the left-hand side and select the current year.
- Select the field you wish to view and click on ‘View satellite images’.
- Select the date you want to view and click ‘Continue’.
- Next, select what you want to use the NDVI map for.
Manual nitrogen allocation:
- Select photos from the previous year to see seed germination in the field.
- Evaluate where more and less seed is needed based on biomass density.
- Enter the desired amounts of seed in kg/ha next to the five NDVI values.
- Enter a title, and save the map in CropMAP and/or download it for use in your machinery.
The yield distribution forecast creates a map based on NDVI values that predicts how much of the field will be harvested.
Generic actions:
- Log in to CropSAT.
- Click on the ‘Upload fields’ button on the left-hand side and select the current year.
- Select the field you wish to view and click on ‘View satellite images’.
- Select the date you want to view and click ‘Continue’.
- Next, select what you want to use the NDVI map for.
Predicting crop distribution:
- Enter the average yield of your field for the previous year and click “Continue”
- You can now see the yield distribution forecast map for your field.
