Particularly, no study has compiled the published values of plant below-ground biomass for the temperate subhumid grasslands of South America. In these grasslands, called Río de la Plata grasslands, grazing is the most frequent disturbance. We set two objectives: (1) to compile and synthesize data of four variables: below-ground biomass, fraction of total biomass allocated below-ground, below-ground net primary productivity and below-ground biomass turnover rate; (2) to estimate the effect of grazing exclusion on below-ground biomass by means of a meta-analysis. There are 15 studies published on six out of eight regional sub-divisions of the Río de la Plata grasslands. © 2023 Ecological Society of Australia.  aBelow-ground biomass turnover  aBelow-ground net primary productivity  aBiomass  aExclusion time  aOpen ecosystem;  aRío de la Plata grasslands1 aOYARZABAL, M.1 aALTESOR, A.1 aPARUELO, J.  tAustral Ecology, 2023.
