    • Addition of organic and inorganic amendments to regenerate the surface structure of silty soils 

      Gabioud, Emmanuel Adrian; Sasal, Maria Carolina; Wilson, Marcelo German; Seehaus, Mariela; Van Opstal, Natalia Veronica; Beghetto, Stella; Wingeyer, Ana Beatriz (Wiley, 2019-11-30)
      The widespread degradation of the structure of silty soils under no till systems (NT) that has been observed in recent years is characterized by the presence of a platy structure (P) near the soil surface. Under these ...
    • A contribution to understanding the origin of platy structure in silty soils under no tillage 

      Sasal, Maria Carolina; Léonard, Joel; Andriulo, Adrian Enrique; Boizard, Hubert (2016)
      In silty soils under no tillage (NT), platy (P) soil structure is widespread and constrains water infiltration. Our objectives were (i) to evaluate how traffic and the presence of crop residues influence P structure ...
    • Crop sequence and P fertilization effects on soil P fractions under no-tillage 

      Appelhans, Estefania Carolina; Novelli, Leonardo Esteban; Melchiori, Ricardo Jose; Gutierrez Boem, Flavio Hernán; Caviglia, Octavio (Springer, 2021-05-27)
      Increasing cropping intensity may affect phosphorus (P) recycling through crop residue inputs, which may differ in soils with different productivity, P adsorption capacity, and P fertilization level. In three crop sequences: ...
    • Developments in the “profil cultural” method for an improved assessment of soil structure under no-till 

      Boizard, Hubert; Peigné, Joséphine; Sasal, Maria Carolina; Guimarães, Maria De Fátima; Piron, Denis; Tomis, Vincent; Vian, Jean-François; Cadoux, Stéphane; Ralisch, Ricardo; Tavares Filho, João; Heddadj, Djilali; De Battista, Juan Jose; Duparque, Annie; Franchini, Julio Cezar; Roger-Estrade, Jean (Elsevier, 2017-11)
      In France, agronomists have studied the effects of cropping systems on soil structure using a field method that is based on a visual description of the soil structure. This “profil cultural” method was designed as a field ...
    • Impact of crop aerial and root biomass inputs on soil nitrifiers and cellulolytic microorganisms 

      Gregorutti, Viviana Carolina; Caviglia, Octavio (Elsevier, 2019)
      In agricultural no-till systems, crop residue management has an important impact on the activity and abundance of soil microorganisms, which play a crucial role in soil health and quality. In these systems, when cover crops ...
    • Platy structure development under no-tillage in the northern humid Pampas of Argentina and its impact on runoff 

      Sasal, Maria Carolina; Boizard, Hubert; Andriulo, Adrian Enrique; Wilson, Marcelo German; Léonard, Joel (2017)
      The no-tillage system (NT) is widespread in the silty soils of the Argentine Humid Pampas. The aims of this study were i) to characterize the evolution of the structure of the A horizon in the northern Humid Pampas due to ...
    • Soil quality impacts of current South American agricultural practices 

      Wingeyer, Ana Beatriz; Amado, Telmo Jorge Carneiro; Pérez Bidegain, Mario; Studdert, Guillermo; Perdomo Varela, Carlos Honorio; García, Fernando O.; Karlen, Douglas L. (Society for Urban Ecology, 2015)
      Increasing global demand for oil seeds and cereals during the past 50 years has caused an expansion in the cultivated areas and resulted in major soil management and crop production changes throughout Bolivia, Paraguay, ...
