For more advanced users Atfarm allows farmers to create variable rate application maps for fertilizer 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.
Variable-rate fertilizer 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 a few steps:
Choose the crop type, fertilizer 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 fertilizer 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 recommendation 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.
