<p>Waterjet technology, with its unique advantages such as cold processing, non-contact operation, absence of chemical residues, and environmental friendliness, has been widely employed in various agricultural applications. This paper provides a comprehensive review of current status and research progress of waterjet technology across key agricultural production stages, including tillage, planting, crop management, and harvesting. Its applications span multiple operational modules such as land preparation, seeding, fertilization, weeding, harvesting operations, washing, peeling, fresh cutting, and equipment cleaning, essentially covering the entire agricultural production chain. Furthermore, based on the principles of waterjet technology, its effectiveness and existing challenges in agricultural applications are analyzed, along with pertinent recommendations. Finally, the integration trends of waterjet technology with artificial intelligence and green energy are discussed, offering insights and references for further expanding the depth and breadth of its engineering applications.</p>
