Crop diversification offers numerous synergistic advantages over intensive monocultures via belowground interspecific interactions. The plant–soil–microbiome interactions that trigger cascading effects underpin the benefits of crop diversification. Unlocking the potential of cascading effects in diversified cropping systems can alleviate common obstacles in intensive monoculture farming. Strategically selecting species and varieties that complement and facilitate one another can enhance agricultural productivity with fewer agrochemical inputs. Crop diversification practices offer numerous synergistic benefits. So far, research has traditionally been confined to exploring isolated, unidirectional single-process interactions among plants, soil, and microorganisms. Here, we present a novel and systematic perspective, unveiling the intricate web of plant–soil–microbiome interactions that trigger cascading effects. Applying the principles of cascading interactions can be an alternative way to overcome soil obstacles such as soil compaction and soil pathogen pressure. Finally, we introduce a research framework comprising the design of diversified cropping systems by including commercial varieties and crops with resource-efficient traits, the exploration of cascading effects, and the innovation of field management. We propose that this provides theoretical and methodological insights that can reveal new mechanisms by which crop diversity increases productivity. [ABSTRACT FROM AUTHOR]
