To start monitoring your crops, you need to add fields to your account first. There are several available options:

  • Upload field
  • Draw field on map
  • Custom Upload (available in Professional Plan only)

Start by clicking +Add Field located in the right bottom corner of your screen.

monitoring_location_of_add_fields_button

A window with available options should pop up.

Monitoring_how_to_upload_fields

Upload fields

This option allows you to upload files containing pre-drawn field contours to the system. For now, 4 different format types are supported for this option: .shp.kml.kmz.geojson.

You can either drag-and-drop files onto the web page or click Add your fields.

monitoring_another_way_to_upload_fields

As soon as the field contours appear on the map along with the field card data in the right sidebar menu, click Add to my fields to complete the operation.

Or you can click Cancel (located just below the Add to my fields button) to abort.

Monitoring_how_to_cancel_field_upload

A modal window will offer you two choices:

  • Save and continue. Press this button to automatically add the uploaded field to the list.
  • Delete and continue. Hit this button if you don’t want to add the uploaded field to the list.

Add more information about the newly uploaded field to ensure maximum efficiency of monitoring.

  • Field Name (for your convenience)
  • Group Name (to better organize your fields in the list)
  • Crop Rotation data* (to manage your fields by the crop name, sowing date, and season.

*Accurate monitoring of vegetation development depends on the correctness of crop rotation data.

Crop rotation

Correct crop rotation data includes 3 components: name of the crop, sowing date, and the season when the crop was or is going to be harvested.

Monitoring_where_to_select_crop_data

Note: It is necessary you click on the exact sowing date in the calendar box. Make sure the selected date looks blue in the calendar. 

Draw Field

The Draw polygon option is employed to contour and add your field to the map.

Monitoring_how_to_draw_first_field

After it’s done, click the Add to my fields button and enter a name, select crop name, sowing date and season of its cultivation to the relative box. Then click Save to add a field to your Field List.

Field Right Sidebar Menu Section

Utilize the field right sidebar menu section to track, review or change activities related to your field with the features designed in Crop monitoring which are Edit Field, Crop rotation, Weather Today and Scouting Tasks.

Edit Field

You can edit your fields whenever you need by going to a three dots menu, then Edit on your Field List.

Monitoring_how_to_edit_drawn_field

Or, Edit on the right of the field card.

Weather Today

Log in every morning to follow the weather not only Temperature but also Wind, Humidity, Clouds, Pressure factors to be up-to-date e.g. you’ve planned to apply a fertilizer and it is going to rain.

Scouting Tasks

In order to send a scout to the field, you should create a scouting task. This task is automatically sent to the mobile application where a scout can pick it up for further execution. To perform the action, click the Add new task button at the bottom of the Task list or assign a task through selecting one of your fields.

Monitoring_how_to_add_new_scouting_task

Drop a pointer on the area you want to inspect and the New task window pops up. It contains the preview of your field with a pointer and field coordinates. Fill in the appropriate boxes with Task name and Description and click Save. Once it’s done, the task immediately appears on your task list, as well as on the mobile application connected to your account.

Raster Image

Currently we use Sentinel-2 sensor and satellite images with no more than 50% cloudiness. In this way, the collected statistics includes representative selection and excludes outside factors.

Indices

Below are the most commonly used vegetation indices that are presented in Crop monitoring:

NDVI or Normalized Difference Vegetation Index

NDRE or Normalized Difference RedEdge

MSAVI or Modified Soil-Adjusted Vegetation Index

RECI (or red-edge chlorophyll index). The red-edge band is a narrow band in the vegetation reflectance spectrum between the transition of red to near infra-red.

RECI is most often used when assessing the chlorophyll content in plant leaves by multispectral data, which has an extreme red-edge channel. The red edge is a region in the red-NIR transition zone of vegetation reflectance spectrum and marks the boundary between absorption by chlorophyll in the red visible region, and scattering due to leaf internal structure in the NIR region.

NDVI, NDRE, MSAVI, RECI are indices that can be selected either from the left drop-down menu or three-dots menu on the small panel above the analytics window.

Download

Using a small panel above the analytics window, you are able to download e.g. the NDVI map in .tiff or .shp formats. Shape format gives you the pixel-by-value NDVI at each point and TIFF format shows a regular image with the NDVI applied.

Statistics

To expand the statistics to check the index of your field, use the small panel above the analytics window. Statistics can be displayed in hectares or percentage.

Cloudiness

We do not upload satellite images with more than 50% cloudiness. When using an index, there should be no outside factors that can influence the whole picture. With this said, we consider the possibility of getting value from 50% cloudy images as a positive one. Statistics displays in ha and percentage.

Monitoring_location_of_clouds_data

Date Line

Shows all images that are less than 50% cloudy. When you pick a date, you see a satellite image with an index applied for that day.

Graphic

The analytics window automatically unfolds on the bottom of the screen by selecting the field.

Graphic Legend

Graphs that display a representation of NDVI (normalized difference vegetation index) are in the center of this window.

There is also the possibility of years comparison, thus you can monitor how your crop is developing compared to data collected in the past. To visualize the data for the specific date, hover over the curve.

Vegetation Season Indices

Each curve can be disabled by clicking the corresponding colored buttons on the legend. This allows you to disable the unnecessary items and compare indices for years of interest.

Weather Curves

To add weather data to the graph, select Temperature or Moisture from the Weather data drop-down list.

Monitoring_where_to_find_weather_data_list

The Cold stress curve highlights the dates in Spring and Autumn when the temperature is below (-6) at which winter crops die.

Monitoring_where_to_find_cold_stress_data

The Heat stress curve (the days in Spring and Summer) reflects the risks associated with drought. In such a way, when the temperature is above (+30) then the growth of the crops slows down. You can track draw down zones on plots with extreme temperatures.

Monitoring_where_to_find_heat_stress_data

Growth Stages

Use Growth Stages to get to know what stage your crop is on right now. If not needed, you are always able to hide the curve from being displayed by clicking on the Growth Stages.

Note! You should add info about crop rotation to see growth stages of your crops.

Period Intervals

By default, it shows one year period or the date range selected on the calendar.

If you set a date range and want to get the default year period view, click Update.
