    • A novel mechanism to simulate intercropping and relay cropping using the DayCent model 

      Della Chiesa, Tomas; Del Grosso, Stephen; Hartman, Melannie; Parton, William; Echarte, Laura; Yahdjian, Laura; Piñeiro, Gervasio (Elsevier, 2022-01-03)
      Combining different crops in complex spatial and temporal arrangements can increase resource use efficiency and reduce negative environmental impacts in croplands. Simulation models are useful tools to explore new management ...

    • Adequate vegetative cover decreases nitrous oxide emissions from cattle urine deposited in grazed pastures under rainy season conditions 

      Chirinda, Ngonidzashe; Loaiza, Sandra; Arenas, Laura; Ruiz, Veronica; Faverin, Claudia; Alvarez, Carolina; Savian, Jean Víctor; Belfon, Renaldo; Zuniga, Karen; Morales-Rincon, Luis Alberto; Trujillo, Catalina; Arango, Miguel; Rao, Idupulapati; Arango, Jacobo; Peters, Michael; Barahona, Rolando; Costa, Ciniro; Rosenstock, Todd; Richards, Meryl; Martinez Baron, Deissy; Cardenas, Laura (Nature Publishing, 2019-01-29)
      A decline in pasture productivity is often associated with a reduction in vegetative cover. We hypothesize that nitrogen (N) in urine deposited by grazing cattle on degraded pastures, with low vegetative cover, is highly ...

    • Cover crop species can increase or decrease the fertilizer-nitrogen requirement in maize 

      Carciochi, Walter Daniel; Massigoge, Ignacio; Lapaz Olveira, A.; Reussi Calvo, Nahuel Ignacio; Cafaro La Menza, Francisco; Sainz Rozas, Hernan Rene; Barbieri, Pablo; Di Napoli, M.; Gonzalez Montaner, J.; Ciampitti, Ignacio A. (American Society of Agronomy; Estados Unidos, 2021-07-03)
      Cover crop species and termination date could affect fertilizer-N management and N diagnostic methods traditionally used in bare fallow-maize (Zea mays L.) systems. Our objectives were to (a) assess the impact of cover ...

    • Crop intensification with sustainable practices did not increase N2O emissions 

      Casanave Ponti, Sheila Mailén; Videla, Cecilia; Monterubbianesi, María Gloria; Andrade, Fernando Hector; Rizzalli, Roberto Héctor (Elsevier, 2020-04-15)
      Nitrous oxide (N2O) is the most important greenhouse gas produced by agricultural soils and is a byproduct of microbial nitrification and denitrification processes. The N2O emission rates depend on soil, climatic ...

    • Effect of intensified cropping sequences on soil physical properties in contrasting environments 

      Crespo, Cecilia; Wyngaard, Nicolás; Sainz Rozas, Hernan Rene; Studdert, Guillermo; Barraco, Miriam Raquel; Gudelj, Vicente Jorge; Barbagelata, Pedro Anibal; Barbieri, Pablo (Elsevier, 2021-08-27)
      Soybean (Glycine max (L.) Merr.) monoculture contributes to soil degradation. Intensification of soybean-based sequences through polyculture, cover crops (CC), and crop fertilization can enhance soil physical quality and ...

    • Effect of the intensification of cropping sequences on soil organic carbon and its stratification ratio in contrasting environments 

      Crespo, Cecilia; Wyngaard, Nicolás; Sainz Rozas, Hernan Rene; Studdert, Guillermo; Barroco, Mirian; Gudelj, Vicente Jorge; Barbagelata, Pedro Anibal; Barbieri, Pablo (Elsevier, 2021-01-19)
      In environments where continuous agriculture leads to soil organic carbon (SOC) depletion, intensification practices (i.e. polyculture, cover crops (CC), and crop fertilization) have been suggested as strategies to improve ...

    • Improving soil organic nitrogen and sulfur pools by cover cropping and crop fertilization in soybean-based cropping systems 

      Crespo, Cecilia; Wyngaard, Nicolás; Sainz Rozas, Hernan Rene; Barbagelata, Pedro Anibal; Barraco, Miriam Raquel; Gudelj, Vicente Jorge; Barbieri, Pablo (Elsevier, 2021-07-10)
      Nitrogen (N) and sulfur (S) define crops productivity, and are currently deficient in most agricultural soils. In agricultural systems, management practices can affect N and S organic pools (Norg and Sorg, respectively). ...

    • Incorporación de cultivos de cobertura previos a soja en el sudeste bonaerense 

      Martinez, Juan Pablo; Barbieri, Pablo Andres; Sainz Rozas, Hernan Rene; Echeverria, Hernan Eduardo (2013-06)
      En la zona del sudeste bonaerense existe escasa información sobre las eventuales ventajas de la incorporación de los CC en los planteos productivos actuales, la cual sería de suma utilidad para evaluar la factibilidad de ...

    • Secuencia de cultivos con predominio de soja: efecto sobre indicadores de calidad física del suelo. 

      Martinez, Juan Pablo; Crespo, Cecilia; Cuervo, Matías Tomás; Sainz Rozas, Hernan Rene; Echeverria, Hernan Eduardo; Martinez, Fernando Gabriel; Cordone, Graciela; Barbieri, Pablo (Asociación Argentina de la Ciencia del Suelo, 2020-12)
      El aumento en la frecuencia del cultivo de soja y de su monocultivo puede provocar disminuciones en la materia orgánica del suelo (MO) y afectar sus propiedades físicas. Sin embargo, prácticas de manejo como la fertilización, ...

    • Soil organic carbon in cropping sequences with predominance of soya bean in the argentinean humid Pampas
