Fecha de publicación: 30/05/2013 Fuente: Wipo "precision farming" The present invention relates to a sustainable strategy for controlling weeds using an device having an automatic GPS-RTK-controlled lateral movement, with centimetre-level precision. This level of precision allows weeds to be removed mechanically from areas close to the crop and thus reduce the use of chemicals on row crops (cotton, beet, tomato, etc.). The invention falls within the fields of precision farming and natural-resources engineering.
