There are new technologies that capture data on the status of the soil remotely, analyse the digital images they produce, and use this information to identify the need for herbicides or fertilizers in specific spots across the field they are surveilling.
The great advantage of those technologies is that they are very precise and do not interfere with the land, but at the same time enable localised treatment to control weeds that would otherwise threaten planted crops‘ access to nutrients, water and sunlight, ultimately impacting the productivity of the cultivated area.
The possibility to identify infested spots and to analyse weed density and the weed species, means that the application of herbicides is minimised to what is really needed to help crops flourish. This, combined with glyphosate’s ability to control weeds for a long time, can result in a reduction of pesticide use of up to 90%.
