    • Denitrification in a Soil under Wheat Crop in the Humid Pampas of Argentina 

      Picone, Liliana; Videla, Cecilia; Picaud, Calypso Lisa; García, Fernando Oscar; Rizzalli, Roberto Héctor (Scientific Research, 2014-09)
      The need to accurately estimate gaseous nitrogen losses from soils is required to have a better understanding of the processes involved as well as soil and environmental conditions, and management practices contributing ...

    • Distribución de tamaño y estabilidad de agregados en molisoles bajo labranzas contrastantes 

      Roldan, Maria Florencia; Studdert, Guillermo; Videla, Cecilia; San Martino, Silvina; Picone, Liliana (2014)
      Los sistemas de labranza afectan la agregación del suelo y su estabilidad, por acción directa y por alterar otros factores tales como el contenido de materia orgánica (MO). Los cambios en ambas variables pueden ser ...

    • Drivers of N2O emissions from natural forests and grasslands differ in space and time 

      Araujo, Patricia Ines; Piñeiro Guerra, Juan Manuel; Yahdjian, Laura; Acreche, Martin Moises; Alvarez, Carolina; Alvarez, C.R.; Costantini, Alejandro Oscar; Chalco Vera, Jorge Elías; De Tellería, J.M.; Della Chiesa, T.; Lewczuk, Nuria; Petrasek, M.; Piccinetti, Carlos Fabian; Picone, Liliana; Portela, Silvina Isabel; Seijo, Sebastian; Videla, Cecilia; Piñeiro, G. (Springer, 2020-06-30)
      Understanding the drivers of greenhouse gas (GHG) emissions is one of the most critical global environmental challenges to mitigate the increasing global temperature. Nitrous oxide (N2O) emissions are highly variable in ...

      Picone, Liliana; Bayer, Cimélio; Videla, Cecilia; Rizzalli, Roberto Héctor; Casanave Ponti, Sheila Mailén; Andrade, Fernando Hector; Garcia, Fernando (Elsevier, 2021-01-14)
      The objectives of this study were i) to measure the soil N2O fluxes in a cropping system currently adopted by farmers of the region (FP), and in an ecologically intensified cropping system (EI) over two consecutive maize ...

    • Soil respiration response to reductions in maize plant density and increased row spacing (Southeast pampas, Argentina) 

      Lewczuk, Nuria; Picone, Liliana; Echarte, María Mercedes; Alfonso, Cecilia; Rizzalli, Roberto Héctor; Echarte, Laura (Elsevier, 2024-09)
      Previous studies have recognized the influence of crop cover and agricultural management on variables (soil temperature, soil moisture, and root biomass) that influence soil respiration. However, despite the influence of ...
