The Zero Tillage (ZT) or Non-Tillage system constitutes an agricultural production approach designed for improved soil conservation, reduced fossil fuel usage, mitigation of waterway pollution, water and wind erosion, addressing compaction, among other objectives. In this way, ZT promises more sustainable agriculture. However, current systems depend on herbicide applications weed control. use herbicides with the same modes action over many years has led to numerous resistant species, which end up threatening success control and, consequently, overall system. Being able automatically detect classify species directly under sprayer during chemical application is alternative populations weeds since it would allow selecting dose those particular species. This study, conducted 15 in commercial fields utilizing management, examined various ground covers intrinsic originating from previous crops residues post-harvest. features a broad spectrum contexts due complexity different cover types, challenge computer vision techniques. assessment focused automatic detection classification most problematic monocotyledonous dicotyledonous province Cordoba Argentina, objective enabling targeted selective their These are Amaranthus palmeri, Echinochloa crus-galli, Eleusine indica, Parietaria debilis Conyza sumatrensis. Additionally, some belong botanical families several morphological resemblances that defy algorithms. work proceeded through machine learning applied such as SIFT (scale-invariant feature transform), K-means (clustering), Bag Features Support Vector Machine classification. results showed accuracy between 89 % 98 allowing significant reduction while applying adequate active ingredient. Moreover, virtual binary maps patches devised be implemented ISOBUS protocol. Thus research contributes significantly issue controlling agriculture
