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 over time.
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.
For more advanced users Atfarm allows farmers to create variable rate application maps for fertiliser application.
Atfarm uses automatically updated satellite information based on 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.
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 a few steps:
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 is an easy-to-use and intuitive tool that allows you to visualise biomass on your fields and create application maps to optimise your nitrogen fertilisation.
Atfarm helps you to plan your field trips more efficiently by checking the fields from your computer before you go there:
Like in Google Maps, this detailed map is made from images taken from an airplane. This is expensive and usually paid by local governments. Therefore these maps can be 1 to 10 years old.
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.
