Pesticide dynamics in agroecosystems: Assessing climatic and hydro-physical effects in a soybean cycle under no-tillage
Behrends Kraemer, Filipe; Castiglioni, Mario Guillermo; Chagas, Celio Ignacio; De Paula, R.; Sainz, Daiana Soledad; De Geronimo, Eduardo; Aparicio, Virginia Carolina; Ferraro, Diego Omar (Elsevier, 2022-09)The high rate of No-Tillage (NT) adoption in Argentina has been followed by conspicuous application of herbicides due to RR crops selection and recently due to weed resistance. In addition, no-tillage in the Rolling Pampa ... -
Pores size distribution and pores volume density of mollisols and vertisols under different cropping intensity managements with no - tillage
Behrends Kraemer, Filipe; Castiglioni, Mario Guillermo; Morras, Héctor José María; Fernández, Patricia; Alvarez, Carina (Elsevier, 2021-09-15)In the Argentina Pampas, one of the most extensive agricultural areas in the temperate fringe of southern hemisphere, soil health is jeopardized mostly by the decline of physical and biological properties due to soil ... -
Soil hydro-physical variables and crop residues determinate runoff soil loss, and glyphosate and AMPA concentration in the aqueous phase under simulated rainfall events
Sainz, Daiana Soledad; Behrends Kraemer, Filipe; Carfagno, Patricia; Eiza, Maximiliano Joaquin; Chagas, Celio Ignacio (Wiley, 2024-07-09)Soil structural degradation and water erosion processes were observed even in no-tillage schemes in the Pampas region. Within these conservation systems, agrochemical application per hectare is one of the highest globally. ... -
Soil shrinkage curves and micromorphology in contrasting managements.
Fernández, Patricia L.; Alvarez, Carina Rosa; Behrends Kraemer, Filipe; Morras, Hector; Scheiner, Javier; Boivin, Pascal; Taboada, Miguel Angel (Asociación Argentina de la Ciencia del Suelo, 2020-06-01)Compaction processes are generally described using methods that do not distinguish volume changes of diffe rent types and pore sizes. The adjustment of shrinkage curves (ShC) using the XP model allows elucidation of the ... -
Soil structure and glyphosate fate under no-till management in the Pampa region. I. Soil structural anisotropy and hydro-physical behavior
Behrends Kraemer, Filipe; Sainz, Daiana Soledad; Morras, Héctor José María; Carfagno, Patricia; Eiza, Maximiliano Joaquin; Fernandez, P.; Chagas, Celio Ignacio (Elsevier, 2022-05-03)Several studies have reported a frequent occurrence of platy structures in soils under no tillage (NT), mostly in silty ones. The objective of this study was to evaluate the morphological features and the pore architecture ... -
Soil structure and glyphosate fate under no-till manangement in the pampa region. II. Glyphosate and AMPA persistence and spatial distribution in the long-term. A conceptual model
Morras, Héctor José María; Behrends Kraemer, Filipe; Sainz, Daiana Soledad; Fernández, Patricia; Chagas, Celio Ignacio (Elsevier, 2022-07-14)Glyphosate and AMPA were measured in a no-tilled (NT) soil and in the runoff resulting from the rain simulation carried out after 270 days of the application of the herbicide. Glyphosate concentration was in low values in ...
