Monitor crop growth, plan nutrition, fertilise variably and increase yield, all with the Atfarm platform and even without variable spreaders. Crop Satellite Monitoring Discover the areas of high potential and crop variability on your fields in one click. Detect problems early and efficiently monitor nitrogen applications, all via detailed satellite imagery. Optimised maps allow you to easily monitor crop development with never- before-seen precision. Both the Optimised map and N-Uptake maps are the first maps of their kind, with the N-Uptake map allowing you to easily see estimates of the total nitrogen your crops have absorbed, all presented in a colour coded map so that you can effectively monitor your fields remotely. Variable N-Rate Application (VRA) Easily apply nitrogen where it most counts, improve the efficiency of your nitrogen use and improve your yield, all according to your crops’ needs. Create a VRA map that displays which crops need the most nitrogen. No terminal? Use the Atfarm app and smartphone GPS to manually adjust your spreading. N-Tester BT Optimise your nitrogen applications and find out crops’ specific nitrogen requirements with the N-Tester BT. Seamlessly integrated with the Atfarm app, simply take your crops’ measurements with the N-Tester and Atfarm will provide you with nitrogen recommendations tailored to your crops. Hundreds of field trials and decades of research have proven the N-Tester's efficacy at identifying crop nitrogen needs. N-Photo Analysis Getting precision nitrogen use estimates with Atfarm is as easy as taking a photo. Simple snap a few photos of your crops with Atfarm, and the app will work out your crops’ nitrogen needs according to their current colour, for accurate, hassle-free insights that are all backed by decades of Yara’s research and development. Field Weather  Always know the optimum times for precise application with the Atfarm Field weather function. Intuitive, colour-coded timetables display optimum spraying and spreading windows over the next 5 days.
