Jorin Grimsdale - Farmer, Scotland
“Atfarm is very simple to use, taking just 10 mins to load all my field boundaries over the 2200 hectares of farming. I like to use satellite imagery to scout for any management issues. The maps are a very visual way of picking out differences in growth and development to help prioritise decisions. There are plenty of products being developed for farmers, but some do not deliver and I wouldn’t recommend, however I would recommend farmers to try Atfarm.”
Remy Dumery - Farmer, France
"If you want to take the first step towards precision agriculture, feel free to test to create simulations on Atfarm. This will allow you to understand the potential of this tool."
Fabiano Paganella - Agronomist, Italy
"It's much better than the solutions that we saw in the past, and we also can see the field from above and identify problematic areas or that have some deficiencies"
Dr Alastair Leake - Director of Policy at the Game & Wildlife Conservation Trust, England
"Nitrogen Use Efficiency is one of the most significant challenges mankind faces if we are to reduce carbon and nutrient emissions yet feed a growing global population. The Yara N tester BT is a valuable and practical tool for farmers to use, backed by decades of research results, to improve efficiency.”
So, what is Atfarm?
Atfarm is an online service that allows farmers and agronomists to remotely monitor fields and identify variations in crops at any growth stage. Biomass distribution on fields can be monitored and consequently variation in crops can be identified. Atfarm brings the possibility to monitor the biomass distribution on fields to make informed decisions to implement precise Nitrogen fertilization. With a few clicks the user is ready to go. Farmers, advisors and even organizations can register online at the Atfarm web page (www.at.farm) and import field manually using shapefiles or maps. With high resolution satellite and biomass images of Atfarm, the user recognizes the smallest growth variation within fields. The user retains an overview of plant growth in the course of the vegetation with current and historical satellite images and can make comparisons of previous years. Atfarm allows the farmer to create Nitrogen application maps for all types of crops based on biomass info. These maps will work regardless of manufacturer and machine technology. For these purposes, Atfarm is using satellite images (each 3-5 days) if the cloud cover enables images. The images are taken via ESA Sentinel 2 satellites.
There are three key functions in Atfarm:
Free biomass monitoring
With the easy-to-use platform Atfarm comes the possibility to remotely monitor the biomass status of your fields and identify variations in crops at any growth stage and make informed decisions regarding your nitrogen fertilization.
The biomass monitoring is a free to use tool in Atfarm application. The biomass overlay gives you an insight into the density of the biomass on fields. A general overview of growth can be obtained and areas with a lack of biomass can be seen.

Variable Rate Application (VRA) maps for Nitrogen fertilization
On the strength of the unique N-sensor algorithm, your generated biomass maps can now be used to create VRA maps which makes differences visible, especially in the late growth stages of crops as canopy is saturating.
As fields can be imported or manually drawn in Atfarm, VRA maps can be created and adapt individually for each field in order to optimize your nitrogen fertilization. These VRA maps can be exported to a terminal as a VRA spreader or they can be sent to smartphones in case users are using their smartphones as a terminal on free Atfarm mobile app.
Benefits of VRA Map:
- Efficient increase in nitrogen use
- Decrease Nitrogen remains in the soil after harvesting, which leads to a decrease in leaching risk
- Decrease in Nitrogen balance surplus
- Facilitating growth difference compensation within a field
- Decrease crop lodging risk
- Improve harvest due to homogeneous plant growing
- Improve yield and protein content depending on weather conditions

Getting Nitrogen recommendations
Our free Photo Analysis can be used to analyze oil seed rape and winter cereals in early growth stages. Simply take a picture of your plant with your smartphone camera in Atfarm mobile app and get a Nitrogen recommendation.
Moreover you can analyze various crop types in later growth stages with N-Tester-Analysis done by Atfarm mobile app and N-Tester BT. Obtained Nitrogen recommendations from N-Tester BT can be used as the basis of creating VRA maps.
Why should I use a combination of N-Tester BT and VRA map in Atfarm?
- With the N-Tester BT, users can understand when and how much Nitrogen is required for crops . By using Atfarm in addition, how Nitrogen fertilizers should be distributed on fields can be determined.
- You will work more resource-efficiently and in a more environmentally friendly way while improving quality and ensuring yields.
- You have a holistic view of your fields and you can detect anomalies in time and react to them with appropriate measures. This applies not only to fertilization but also to e. g. plant protection.
- You have an almost complete traceability and documentation of the measured values and thus, you can make decisions to increase your operational efficiency.
- You can record the Nitrogen supply status for each area again and again and generate VRA maps from the Nitrogen recommendations at any time.
Will Atfarm be available in my country?
The availability of Atfarm and it's modules vary from country to country.
For the Photo Analysis the available calibrations for crop types, the measuring method and the measurement output vary from country to country. For the N-Tester Analysis the available calibrations for crop types and the measuring method vary from country to country.
We are working on expanding the availability of Atfarm, so that more and more farmers and agronomists can improve their fertilization.
To check what exactly is available for your country, please contact our Customer Support Team.
How can Atfarm helps me if I already have an N-Sensor?
Atfarm and the N-Sensor complete each other. While the N-Sensor (Tractor mounted) works well even on cloudy days where satellite images can't be used, Atfarm has the benefit of frequent and easy updates. Additionally, Atfarm lets you adjust your VRA map prior to the application.
