Atfarm is a free online service that allows farmers and agronomists to remotely monitor fields and identify variations in crops at any growth stage.
This Atfarm image shows a field with 3 different seeding dates. You can clearly see 3 clear zones with low to high biomass. With Atfarm you can easily follow how these differences get bigger or less.
Satellite images will not be able to tell you what the problem is but help you decide to have a closer look and then decide on the right actions.
How Atfarm works
Add your fields
Draw your fields and access satellite images analysed with Yara N-Sensor technology.
Start growth monitoring
Monitor the biomass of your fields with Atfarm and use the Yara N-Sensor index to make more informed decisions.
What do farmers and agronomists say about Atfarm?
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.”

For more advanced users Atfarm allows farmers to create variable rate application maps for fertiliser application.
Atfarm uses automatically updated satellite information based the N-Sensor index all in an easy-to-use platform. It is also possible to also adapt the application map according to individual needs and knowledge of a field.
For the analysis of satellite images, Atfarm combines an intuitive and easy-to-use platform with the N-Sensor algorithm, a technology developed by Yara using decades of field trials.
Variable rate fertiliser application
How does variable rate application work?
Using Atfarm is simple – you only need to sign up online and add your fields to check their biomass levels.
You can create an application map in few steps:
Choose the crop type, fertiliser and target N amount.
Generate an application card for working with the required information.
Export the file for your tractor’s monitor and you’re ready to go.
Do I need a variable rate spreader?
No- Atfarm can be used even if you don't have a variable rate spreader - Atfarm can be used via the Atfarm mobile app which is available for both iPhone and Android phones from the usual app stores.
This allows any farmer to variably apply nitrogen, even if they do not have a variable rate controller on their fertiliser spreader. This is possible by using the GPS location from the phone and manually adjusting the flow rate or forward speed (if this is possible without changing pto speed) based on the recomendation given by the app.
There will be some limitations depending on tractor and spreader capabilities but this should allow many more farmers to take advantage of variable rate spreading.

Atfarm helps you to plan your field trips more efficiently by checking the fields from your computer before you go there:
Which field seems to grow slower and need a check?
Which areas in the field need closer inspection?
If I need to take a sample in the field, where is the best place?
Atfarm will not solve crop problems, but helps you to find out quicker. When you know where they are, you can try to fix them. Some can be fixed this season, but others possibly only for next season or never. This depends on the cause.
Atfarm and the N-Sensor complement each other. With the N-Sensor, the accuracy of the biomass measurement is better thanks to the sensors in the field and with Atfarm, you quickly have biomass maps updated several times a week.
In order to create an application map, first, choose the crop type that is planted on your field. Input all information and click on create application map. The application map is being created automatically for you based on Yara's N-Sensor algorithm.
A satellite can not see through clouds. Atfarm automatically filters out these images. Sometimes a small cloud is visible. This image can not be used. Luckily images are taken every 2-4 days, so the cloud problem is smaller than with earlier satellites.
Atfarm is free to use for biomass monitoring on unlimited fields and you can create a nitrogen application map for one field for free. To create unlimited nitrogen application maps you need to buy an annual subscription.
The cost of a year's subscription is currently (March 2020) £195 per year.
The app offers most of the functions of the website version. So feel free to try it. It allows you to use Atfarm on your smartphone when you are outside. The app also enables VRA through manual actions as variable driving speed, so you can test VRA also with older equipment.
Atfarm is originally designed to enable variable rate application of nitrogen (VRA). This is the advanced level in Atfarm or in other words, the next step after crop monitoring. For many farmers the preparation might take a bit longer. However, you are free to try one field. After that VRA will cost €195/yr. VRA is most easy to execute with a modern spreader and GPS. Atfarm can create the tasks or shape files to do it.
