Contenido :  Abstract:Agroecosystem simplification and intensification affect soil organisms and earthworms in particular, due to physical disturbance and biological changes in the soil habitat in addition to the use of pesticides and reduction in organic matter. Historically, production systems have centered on physical and chemical properties and processes, with lesser value given to biological ones. The main land use systems in Uruguay have not escaped this reality. Therefore, their validation as sustainable land use systems must consider biological aspects of production and the study of their relationships with soil physical and chemical properties. Therefore, in two long-term experiments in Uruguay, earthworm communities were studied to assess the impact of land use intensity on their populations and to explore their relationships with various soil physical and chemical properties and surface residues. In one experiment, located in eastern Uruguay (UEPP-INIA Treinta y Tres) four different rotations (continuous cropping, short crop-pasture rotation, long crop-pasture rotation, and pasture improvement) under grazing and no tillage conditions were evaluated. The control was an adjoining area with natural grassland used as a pasture. In the other experiment, located in northern Uruguay (UEG-INIA Tacuarembó), two natural grasslands were evaluated, one under grazing and the other excluded from grazing for nine years. The results indicated that management practices such as rotation and gra... Presentar Todo
