    • 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 ...

    • 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 ...
