    • Cover crop benefit bacteria and increase aggregate-associate soil C and N storage 

      Fontana, Marianela B.; Novelli, Leonardo Esteban; Sterren, María A.; Uhrich, Walter G.; Rondán, Guillermo A.; Barbagelata, Pedro Anibal; Benintende, Silvia M. (Elsevier, 2024-03)
      The aim of this study was to analyze the effect of four crop sequences with different aboveground biomass and crop residue biochemical composition on biological soil variables, fractions of soil organic matter, and soil ...

    • Impact of Crop and Residue Management on the Physical and Chemical Stabilization of Soil Organic Matter at Farm Level 

      Wingeyer, Ana Beatriz (University of Nebraska, 2011)
      This dissertation explores changes over time in soil organic matter (SOM) stabilization of two irrigated production fields: a continuous maize sequence that was converted from no-till to conservation deep tillage (Site 1), ...

    • Importancia del campo natural para el almacenaje de carbono en sistemas ganaderos de cría 

      Eclesia, Roxana Paola; Lezana, Lucrecia; Zamboni, Pamela; Canavelli, Sonia Beatriz (Estación Experimental Agropecuaria Paraná, INTA, 2020)
      El incremento en el almacenaje de carbono (C) en la materia orgánica del suelo (MOS) y en la biomasa vegetal surge como una estrategia para contrarrestar las emisiones de gases de efecto invernadero (GEI) en los sistemas ...

    • Increased cropping intensity improves crop residue inputs to the soil and aggregate-associated soil organic carbon stocks 

      Novelli, Leonardo Esteban; Caviglia, Octavio; Piñeiro, Gervasio (Elsevier, 2017-01)
      Many South American agroecosystems are based mainly on soybean [Glycine max (L.) Merr.] as a sole crop in the year, which has increased concerns regarding soil conservation and ecosystems sustainability. The increase in ...

    • Predicting soil test phosphorus decrease in non-P-fertilized conditions 

      Appelhans, Stefania Carolina; Carciochi, Walter Daniel; Correndo, Adrián A.; Gutierrez Boem, Flavio Hernán; Salvagiotti, Fernando; García, Fernando O.; Melchiori, Ricardo Jose; Barbagelata, Pedro Anibal; Ventimiglia, Luis Alberto; Ferraris, Gustavo Nestor; Vivas, Hugo Silverio; Caviglia, Octavio; Ciampitti, Ignacio A. (Wiley, 2020-02)
      Monitoring the availability of phosphorus (P) in soil under continuous cropping facilitates finding deficiency in crops and contributes to improving crop growth and nutrient management models. Soil P availability for 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, ...

    • Vertical distribution of root biomass and soil carbon stocks in forage cropping systems 

      Ojeda, Jonathan Jesus; Caviglia, Octavio; Agnusdei, Monica Graciela (Springer, 2018-02)
      Background and aims: Forage cropping systems may differentially affect the vertical distribution of roots and soil organic C stock (C-OM). In annual crops sequences (ACS) and perennial pastures (PP), we assessed the ...
