    • Addition of amendments to restore a compacted soil under no-tillage system 

      Barbieri, Rayner Sversut; Gabioud, Emmanuel Adrian; Wilson, Marcelo German; Sasal, Maria Carolina; Seehaus, Mariela; García-Tomillo, Aitor; Silva, Tatiane Carla; Montanari, Rafael (Universidade Estadual de Maringá, 2023-04)
      The addition of organic and inorganic amendments can improve soil structure and reduce soil compaction. In this context, this study aimed to evaluate whether the application of amendments reduces penetration resistance ...

    • 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 ...

    • Crop sequence and P fertilization effects on soil P fractions under no-tillage 

      Appelhans, Stefania 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 ...

    • 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, ...
