Plant quality and primary productivity modulate plant biomass responses to the joint effects of grazing and fertilization in a mesic grassland

Prepared by Sofía Campana & Laura Yahdjian

(a) Experimental exclosures used in the study site (Flooding Pampa, Argentina) to evaluate the effect of domestic grazing. Plant biomass accumulates inside the exclosure (left) in comparison with the grazed grassland (right). (b) Mobile cage used to estimate cattle consumption and aboveground net primary productivity in the grazed grassland.
