In Atfarm you can remotely check the biomass status of your fields for free with regularly updated satellite images and various biomass layers to

	Make informed decisions for your nitrogen fertilisation based on reliable and comprehensive growth information
	Identify areas with high growth potential
	Identify potential problem areas on time before yields are affected
	Recognise crop variability due to weather
	Plan next field visits and prioritise areas that require a closer look
	Analyse progress and evaluate any new practices or products you are testing
	Monitor effectiveness of nitrogen applications and variable fertilisation

How it works

Add your field

Access our free Cop Monitoring Solution both via the Atfarm web app in your desktop browser and via the Atfarm mobile app on your mobile device.

After adding a field to your farm in your Atfarm account, you can see a satellite image of the field with a biomass layer on it.

Adding fields

Select a satellite image

Satellite images of your fields are taken every 3 to 5 days and uploaded to Atfarm. You can access images from up to 2 years in the timeline below the map.

Cloudy satellite images are hidden by default in the timeline as biomass layers cannot be applied to them and therefore no Variable N-Rate Application (VRA) Maps can be created with such images. But you can still view these images and check whether they are indeed cloudy or whether the detection algorithm has made a mistake.

Viewing cloudy satellite images

Select map view and biomass layer

Click on the map layer tile in the lower right corner of the field map to select different satellite maps and biomass layers.

You can select 2 types of satellite maps to view your field.

Available satellite maps

You can choose between 3 types of biomass layers to apply to a cloud-free satellite image. Each biomass layer uses a specific vegetation index to measure crop health and growth. As a result, you get a biomass map showing the in-field variability, which can be used to create Variable N-Rate Application (VRA) Maps.

Our Yara N-Sensor vegetation index is what makes Atfarm special. It was developed based on our expertise in precision fertilisation and over 25 years of field trials. Using the Yara N-Sensor index, Atfarm generates optimised biomass maps to show the variability in crop development even in advanced growth stages. This is particularly relevant for late nitrogen applications.

Our N-uptake map is optimal to view day specific nitrogen levels in your crop at different growth stages for identifying nitrogen uptake variation within your field.

Available biomass layers

Compare biomass

Compare biomass of your field between two selected dates with our Biomass Comparison tool and benchmark crop development, identify anomalies and discuss possible measures.
