MARTIN, Beatriz; SOSA, Oscar; MONTICO, Sergio y ZERPA, Gabriel. Relación entre las unidades de vegetación y la microtopografía en un pastizal ubicado en un sector mal drenado de Argentina. Cienc. Inv. Agr. [online]. 2007, vol.34, n.2, pp.103-113. ISSN 0718-1620. http://dx.doi.org/10.4067/S0718-16202007000200003.
The spatial distribution of vegetable communities in depressed landscapes from Rolling Pampa (Pampa Ondulada), Argentina is frequently heterogeneous. The objective of this work was to study a possible relationship between topography and functional and structural characteristics of vegetation in a pasture located in a depressed and poorly drained area. The study was carried out in a sector next to a dell from the flowing Ludueña basin. The course of Ludueña extends between 32° 46' and 33° 07' S and 60° 39'and 61° 07'W in the Santa Fe province of Argentina. The identification of the plant communities and a topographical study allowed us to recognize three highly productive forage units. In each unit, primary production, abundance and cover were determined. Plant units were established accordingly. The results obtained suggest that vegetation cover and vegetation abundance from depressed landscapes are highly related with microtopography
