The system is based on what is known as precision agriculture, a concept that emerged using new technology like sensors, drones and GPS navigators, and the idea is based on observing and managing crops in order to apply only the necessary resources at the right time, thus avoiding unnecessary high costs and environmental damage. Specifically, the research used very high spatial resolution multispectral satellite images, able to gather data with spatial details in regions of the electromagnetic spectrum different from those in the range of visible light, meaning it can obtain information that the human eye cannot detect.

Along with this technology, the group analyzed four different plots of wheat for two seasons. After verifying that there had indeed been an increase in the weeds, as pointed out by the head researcher of the study, Isabel Castillejo, they confirmed that these weeds grew in patches, which means that they are good candidates for the use of weedkillers in specific locations, instead of applying them all over the entire plot.

Afterwards - Oats - Ones - Year - Crop

Afterwards, they confirmed that the new wild oats that had sprouted were very nearby and relied on the ones that had grown the first year of crop. "If the new weeds are found near the old ones, we can predict...
