Terrestrial Ecosystem Phosphorus Weathering During Hothouse Conditions and Its Impact on Carbon Cycle
Phosphorus(P)released from soils via chemical weathering(referred to as P weathering)plays a critical role in the global cycling of key elements and significantly influences the size of the Earth's biosphere.Grounded in the modern terrestrial P cycle,this paper provides an overview of recent research on terrestrial P weathering during the Phanerozoic hothouse conditions.Furthermore,it examines the potential impacts of accelerated P weathering on the carbon cycle and proposes future research directions for understanding the terrestrial P cycle.This paper aims to contribute theoretical insights for exploring the dynamics of Phanerozoic hothouse conditions and the carbon cycle,while also offering scientific support for optimizing phosphorus fertilizer use and promoting sustainable agricultural practices in the future.
