Well-known tractor sensors for nitrogen fertilization and plant protection measures use the same measuring principle as satellite images – the reflectance of the vegetation in the visible and near infrared as an indicator for the crop status and the total biomass of the crop.
The same or similar methods can also be used from space. The advantage of this is that no additional calibration runs or zero measure plots in the field are necessary. For the TF Biomass Map, the absolute above-ground dry biomass is derived from satellite data. It can also be provided on cloudy days via coupling with a crop growth model.
With the TF Biomass Map you can
- quickly identify the structure and density of your crop
- optimize the quantity of used pesdicide
- protect your crops effectively and environmentally friendly
TalkingFields Biomass Map
The TF Biomass Map shows the total above-ground dry biomass on the field in t/ha at a specific date. The crop growth can be monitored during the growing season in order to be able to react appropriately to current conditions.
Four TF Biomass Maps will be delivered during growth period at selectable dates. Usually dates shortly before or on the day of a planned task (e. g. fertilization) are used.
For the calculation of the TF Biomass Map, current satellite data are combined with a crop growth model (PROMET). This makes it possible to create maps even at times when there is no high-quality satellite image available
