Abstract. The root zone is a vital part of the Earth system and key element in hydrology, ecology, agronomy, land surface processes. However, its definition varies across disciplines, creating barriers to interdisciplinary understanding. Moreover, characterizing challenging due lack consensus on definitions, estimation methods, their merits limitations. This opinion paper provides holistic from hydrology perspective, including moisture storage, deficit, storage capacity. We demonstrate that plays critical role biosphere, pedosphere, rhizosphere, lithosphere, atmosphere, cryosphere system. underscore limitations traditional reductionist approach modelling this complex dynamic advocate for shift towards holistic, ecosystem-centred approach. argue offers more systematic, simple, dynamic, scalable, observable way describe predict science.
