Abstract. It was analyzed the response of two
grass species to waterlogging, soil-nutrient enrichment and to the combination
of these two factors. Plants of two species occurring in the Flooding Pampa (Argentina), Danthonia
montevidensis and Paspalum dilatatum, were grown in treatments with
two levels of waterlogging and three levels of fertilization. Waterlogging did
not affect total biomass of D. montevidensis, but it slightly promoted
growth of P. dilatatum. Most analyzed variables showed no significant
interaction between fertilization and waterlogging. Therefore, waterlogging
does not produce a detrimental effect either in the growth of these species or
in their response capacity to stimulating growth factors, such as
fertilization.
