    • Capacity and Intensity Indicators to evaluate the effect of different crop sequences and cover crops on soil physical quality of two different textured soils from Pampas Region 

      Salazar, María Paz; Lozano, Luis Alberto; Villarreal, Rafael; Irizar, Alicia Beatriz; Barraco, Miriam Raquel; Polich, Nicolás Guillermo; Soracco, Carlos Germán (Elsevier, 2021-11)
      Soil physical degradation is a current problem in Molisols of the Pampas Region under no-tillage (NT), that has been related to over-simplified agricultural systems with scarce or no rotations and long winter bare fallows. ...

    • Cover crops effects on anisotropy of unsaturated soil hydraulic properties 

      Polich, Nicolás Guillermo; Lozano, Luis Alberto; Villarreal, Rafael; Salazar, María Paz; Melani, Esteban; Soracco, Carlos Germán (Elsevier, 2023-03)
      No tillage (NT) is frequently implemented in simplified agricultural systems, which has negative effects on soil physical quality. Among the suggested practices to preserve the physical fertility of soils under NT are ...

    • Cover crops effects on soil hydraulic properties in two contrasting Mollisols of Argentinean Pampas region 

      Villarreal, Rafael; Lozano, Luis Alberto; Polich, Nicolás Guillermo; Salazar, María Paz; Barraco, Miriam Raquel; Soracco, Carlos Germán (Wiley, 2022-02)
      Decreasing of physical quality of Mollisols in the Argentinean Pampas region is observed due to simplified crop rotations. The main objective of this work was to evaluate the effects of cover cropping management on soil ...

    • Diffusivity and sorptivity determination at different soil water contents from horizontal infiltration 

      Villarreal, Rafael; Lozano, Luis Alberto; Melani, Esteban; Salazar, María Paz; Otero, María Florencia; Soracco, Carlos Germán (Elsevier, 2019-03-15)
      Determination of soil hydraulic properties under non-saturated conditions is crucial in order to describe soil water dynamics in the field. The objectives of this work were: i- to determine soil water diffusivity (D) as a ...

    • Efecto de los cultivos de cobertura sobre el carbono orgánico y la calidad física del suelo en un cultivo de soja 

      Salazar, María Paz; Lozano, Luis Alberto; Villarreal, Rafael; Polich, Nicolás Guillermo; Irizar, Alicia Beatriz; Bongiorno, F.; Bellora, Guido Lautaro; Soracco, Carlos Germán (Asociación Argentina de la Ciencia del Suelo, 2020-10)
      Determinar el contenido y la distribución vertical del carbono orgánico del suelo (COS) y de diferentes fracciones físicas y químicas del COS, en un cultivo de soja bajo siembra directa (SD) con y sin cultivo de cobertura ...

    • Effect of cover crops on hysteresis and anisotropy of soil hydraulic properties 

      Polich, Nicolás Guillermo; Lozano, Luis Alberto; Villarreal, Rafael; Salazar, María Paz; Bellora, Guido Lautaro; Barraco, Miriam Raquel; Soracco, Carlos Germán (Elsevier, 2022-12)
      No till is the main management system for soil conservation world-wide. In Argentina is frequently implemented in simplified crop sequences, which has negative effects on soil physical quality (SPQ). Among the suggested ...

    • Enyesado de suelos sódicos: modificación de sus propiedades químicas, físicas y biológicas 

      Melani, Esteban; Guilino, Facundo; Draghi, Laura Mónica; Jorajuría Collazo, Daniel; Villarreal, Rafael; Lozano, Luis Alberto; Soracco, Carlos Germán; Palancar, Telmo (Facultad de Agronomía, Universidad Nacional de La Plata, 2021-12)
      Los suelos sódicos ocupan una extensa proporción de la Depresión del Salado. El sodio aumenta el pH y provoca la dispersión de las arcillas generando modificaciones en la estructura de los suelos que perjudican el crecimiento ...

    • Glyphosate dynamics in a soil under conventional and no-till systems during a soybean growing season 

      Soracco, Carlos Germán; Villarreal, Rafael; Lozano, Luis Alberto; Vittori, Santiago; Melani, Esteban; Marino, Damian Jose Gabriel (2018-08-01)
      Glyphosate (GLY) is a non-selective herbicide, heavily used world-wide in agriculture, especially under no-tillage (NT) management. The objectives of this work were i - to determine the temporal and vertical variation of ...

    • Hydraulic conductivity and pore connectivity. Effects of conventional and no-till systems determined using a simple laboratory device 

      Soracco, Carlos Germán; Villarreal, Rafael; Melani, Esteban; Oderiz, Juan Agustin; Salazar, María Paz; Otero, María Florencia; Irizar, Alicia Beatriz; Lozano, Luis Alberto (Elsevier, 2019-03-01)
      Soil hydraulic conductivity is a property that describes how easily water can move through a porous space and its determination is important because it controls many soil hydrological processes. The objectives of this work ...

    • Persistencia de los efectos de la descompactación del suelo con paratill
