This chapter extensively explores the intricate dynamics of weed communities within the framework of Conservation Agriculture (CA). A review of weed density, shifts in species, and seedbank dynamics under CA reveals the challenges inherent in this agricultural system. The chapter underscores the implications for ecological weed management, critically assessing the efficacy of the main CA pillars, i.e. minimum soil disturbance, diversified crop rotations, and cover cropping in mitigating weed pressure. Key strategies, such as ecological management of weed-crop competition and oversight of the seedbank and soil nutrients, are examined in-depth. While acknowledging the merits of CA, the chapter addresses challenges, including increase in weed abundance, shifts in weed diversity, and introduction of invasive species. The conclusion of the chapter directs attention to understanding the vulnerabilities of weeds within the CA system and proposes management practices to effectively address these challenges.
