Field Master: Agricultural GPS

FieldMaster is a GPS farm-navigation and farm-management app. It brings field guidance, a Field Management System (FMS), farm records and planning together on your phone.

Use it while spraying, fertilizing, sowing, spreading fertilizer, mowing, cultivating, harvesting or carrying out other field operations. Choose A-B guidance for regular parallel passes, curve guidance for irregular boundaries, or Plan mode to organize the route and reduce unnecessary driving. See your position, distance from the line, worked area and coverage to reduce overlaps and skips. FieldMaster does not automatically steer your tractor.

Create and manage fields by drawing boundaries manually, using GPS measurements or importing existing data. Edit boundaries, measure plots, group fields, assign crops and seasons, and keep information about leases and farm operations in one place. The Field Management System helps you organize fields, crops, machinery, inventory, work history and farm documentation.

During work, you can record passes and treatments, add notes, save the date and working conditions, and assign the operation to a field and crop. You can also add work manually, either to plan a future operation or to complete documentation for work already performed. Treatment records may include the product, dose, comments, weather conditions and season history. Export your data, create backups and generate PDF reports for fields, crops, treatments and completed work.

FieldMaster includes tools for field observation and agronomic planning. Use soil-sample records to keep laboratory results connected with the correct field. NDVI reports from satellite data can help identify areas that may need closer inspection; unusual colours do not diagnose a problem by themselves and should always be checked in the field. The virtual weather station provides local weather information, rainfall monitoring and forecasts. Delta T can support the assessment of spraying conditions, but it is only an aid and never replaces the product label or an on-site evaluation.

New tools include fertilizer planning, an NPK calculator, profitability records, inventory management and machinery management. Plan fertilizer applications, compare nutrient requirements, track products and stock, organize machines and review the costs and results of field operations. Headlands can help plan turns at the ends of fields, while tramlines help organize repeated passes and controlled traffic patterns.

FieldMaster supports phone GPS and external receivers connected through USB, Bluetooth or NMEA. RTK workflows and NTRIP correction data can be used where the receiver, correction service and connection provide them. Accuracy depends on the device, receiver, correction source, signal quality, Android settings, terrain and operating conditions. Always check the displayed position before starting work.

Depending on the selected country or region, the app may provide additional local features such as agricultural market prices, pest alerts, plant-protection product registers, geoportal layers, parcel boundaries, orthophotos, soil information and local agricultural terminology. The availability and scope of these services depends on the data source and the country.

Farm data is kept locally on the device unless you choose to export, back up or share it. Fields, drives, crops, treatments, notes and reports are not publicly visible by default.

FieldMaster is developed for farmers who want straightforward field navigation and better control over farm information. GPS and agronomic information is advisory. Before spraying or carrying out any treatment, assess actual field conditions and follow the product label and local regulations. Trial and subscription details are shown in the app and on Google Play.
