The definitive version is available at: https://www.sciencedirect.com/science/journal/03418162The accurate measurement of soil infiltration rates is a challenging task in hydrological studies, as they are governed by complex interactions between the plant and soil components. To explore the effects of plant roots and soil moisture (SM) on infiltration process, an automatic measurement system based on a point source device was used to determine infiltration rates at different cultivated grasslands (leguminous, gramineous and mixed) in an arid region of China. The results showed that SM and plant roots significantly affected the infiltration process at different stages in the three grasslands. The soil infiltration rates were negatively correlated to SM, but a positive correlation was observed with the below-ground biomass (BGB). SM was the main factor influencing the infiltration rates in the initial stage of infiltration, whereas both SM and BGB determined the steady-state infiltration rates. The influence of the combined effects of SM and plant roots decreased over infiltration time. The decreased rate of determining coefficient showed that SM was more influent than plant roots. These results may contribute to interpret the observed higher soil infiltration capacity in the leguminous grasslands than in the gramineous and the mixed grasslands, and were conducive to better understand the effects of plant and soil properties on infiltration processes in arid areas.This research was funded by the Projects of the National Natural Science Foundation of China (NSFC 41722107), the Light of West China Program of the Chinese Academy of Sciences (XAB2015A04; XAB2018B09), the Fundamental Research Funds for the Central Universities (2452018086; 2452019187), and the Youth Talent Plan Foundation of the Northwest A&F University (2452018025).Peer reviewedElsevierNational Natural Science Foundation of ChinaChinese Academy of SciencesLópez-Vicente, Manuel [0000-0002-6379-8844]Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]201920192019info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Postprintinfo:eu-repo/semantics/acceptedVersionhttp://hdl.handle.net/10261/190648reponame:DIGITAL.CSIC.
