85% savings with PIX4Dfields & DJI Mavic 3 Multispectral

Increasing farming return on investment (ROI) with crop health analysis and input savings through site-specific applications.

Drone-based remote sensing offers substantial benefits across agricultural practices, like enhancing crop health assessment, enabling precise field boundary mapping, or effective weed detection for targeted treatments. The cyclical and demanding nature of agriculture—marked by short seasonal time windows and peak workloads (planting, fertilization, crop care, and harvesting)—often leads to last-minute changes of plans or client requests. This can be challenging for drone service providers. This is why fast and efficient data acquisition is critical for the success of drone service providers and farmers themselves.

An effective precision agriculture solution

Combining DJI Mavic 3 Multispectral’s mapping times of 20-28 minutes, good sensors (20 MP RGB and 5 Megapixel 4 band multispectral), and RTK precision with PIX4Dfields’ fast & offline capabilities and powerful tools gives you the possibility to rapidly create actionable data for agriculture. This data includes field boundaries, scouting maps, as well as variable rate and spot spraying application prescription maps.

Fast identification of areas for variable rate growth regulator application on a wheat field

This case study covered a 50-hectare (124-acre) winter wheat field in Germany. The aim was to assess the overall crop health and development of the winter wheat after the first nitrogen fertilization on March 26, 2024.

The detailed data from this flight pinpointed variations in crop growth. Waterlogged areas could be identified and measured and areas with weak growth based on soil heterogeneity were mapped and used by the farmer for a site-specific growth regulator application. Setting up the drone and transferring data to PIX4Dfields took just 8 minutes. On-site data processing with PIX4Dfields was completed swiftly: 4 minutes 30 seconds for the RGB data and 6 minutes 54 seconds for the multispectral data.

Herbicide spot spraying application on a corn field

This case study was performed on a 40-hectare (99-acre) corn field in Germany before planting on April 5, 2024.

The drone setup and data transfer to PIX4Dfields only took 6 minutes and on-site data processing 14 minutes—overall, data acquisition and processing took just 1 hour and 13 minutes. The flight resulted in a high-resolution aerial weed map, which can be converted via the VARI/TGI RGB indices or the Magic Tool into a prescription map for herbicide spot-spraying. Using the prescription map created in PIX4Dfields for herbicide site-specific application resulted in 85% input savings!
