A simple model for water table fluctuations for agronomic decision making in the Argentinian Pampas
Videla Mensegue, Horacio Rogelio; Magra, Maria Sofia; Macchiavello, Alejandra; Alvarez, Cristian; Noellemeyer, Elke; Caviglia, Octavio (Elsevier, 2025-06)The shallow and fluctuating water table present significant challenges and opportunities for agricultural regions worldwide. This study explores the intricate interplay between water table fluctuations, soil type, potential ... -
Calibration and validation of soil water balance (SWB) model in the Inner Argentinian Pampas
Videla Mensegue, Horacio Rogelio; Caviglia, Octavio; Degioanni, Américo José; Marcos, J.; Bonadeo, E. (Elsevier, 2021-02)Biophysical simulation models can help to satisfactorily estimate the crop performance for grain production, their stability across years and their impact on components of hydrological balance in diverse areas once those ... -
Co-designed farming scenarios show that vegetation is more effective than drainage regulating water excess in the inner Argentinean Pampas
López, Sebastián; Videla Mensegue, Horacio Rogelio; Guillen, Nicolás Federico; Alvarez, Javier; Corigliano, José; Macchiavello, Alejandra; Romero Verastegui, Betsy; Kroon, Timo; Veldhuizen, Albert A.; Salafia, Analía Grisel; Blanco, Paola; Canale, Alejandra; Garcia, Carlos Marcelo; Jobbagy Gampel, Esteban Gabriel (Elsevier, 2025-12)Study region: La Picasa endorheic basin (6 820 km²), Inner Argentine Pampas, one of South America’s most productive rain-fed plains. Study focus: We evaluated how land-use change, rainfall variability and drainage ... -
Functional crop types are more important than diversity for the productivity, profit and risk of crop sequences in the inner Argentinean Pampas
Videla Mensegue, Horacio Rogelio; Caviglia, Octavio; Sadras, Victor Oscar (Elsevier, 2022-02)CONTEXT: Over the last 250 years, many natural ecosystems in South America, including the Inner Pampas of Argentina, evolved into extremely simplified agroecosystems. In the last 25 years, simplified soybean-based crop ... -
Modelling water productivity for ecological intensification of crop sequences in the Inner Argentinean Pampas
Videla Mensegue, Horacio Rogelio; Caviglia, Octavio; Degioanni, Américo José; Marcos, J.; Bonadeo, E. (Elsevier, 2021-09)The design of crop sequences based on ecological intensification (EI) may help to restore lost agroecosystem services and to increase resource use efficiency. Our aim was to evaluate, using a modelling approach, the impact ... -
Soybean yield and water productivity gaps associate with ENSO-dependent effects of fungicide, sowing date and maturity group
Videla Mensegue, Horacio Rogelio; Cordoba, Mariano Augusto; Caviglia, Octavio; Sadras, Victor Oscar (Elsevier, 2024-04)Context: Soybean, the focus of this study, is the most widely sown crop and the main source of external income in Argentina. The reported soybean yield gap calculated as the difference between water-limited potential yield ...
