    • Extrapolation of a structural equation model for digital soil mapping 

      Angelini, Marcos Esteban; Kempen, Bas; Hauvelink, Gerard B.M.; Temme, Arnaud J.A.M.; Ransom, Michel D. (Elsevier, 2020-05)
      In theory, two separate regions with the same soil-forming factors should develop similar soil conditions. This theoretical finding has been used in digital soil mapping (DSM) to extrapolate a model from one area to another, ...

    • Genesis of subtropical soils with stony horizons in NE Argentina: Autochthony and polygenesis 

      Morras, Hector; Moretti, Lucas Martin; Piccolo, Gabriel Agustin; Zech, Wolfgang H. (Elsevier, 2009-03)
      Deep red soils, combining characteristics of highly weathered materials together with a significant degree of clay illuviation and with stony horizons close to the saprolite, are found in the Province of Misiones, northeastern ...

    • Génesis de suelos en un sector del piedemonte aluvial del Chaco salteño 

      Moretti, Lucas Martin; Rodriguez, Dario Martin; Angelini, Marcos Esteban; Morras, Hector (2012-12)
      Se estudia la relación suelo-paisaje, las propiedades físico-químicas y la composición mineralógica de diferentes suelos dentro del cono aluvial del río Del Valle, en el borde occidental del Chaco salteño, en la provincia ...

    • Mapping the soils of an Argentine Pampas region using structural equation modeling 

      Angelini, Marcos Esteban; Hauvelink, Gerard B.M.; Morras, Hector; Kempen, Bas (2016-11)
      Current digital soil mapping (DSM) methods have limitations. For instance, it is difficult to predict a large number of soil properties simultaneously, while preserving the relationships between them. Another problem is ...

    • A new soil-landscape approach to the genesis and distribution of typic and vertic Argiudolls in the Rolling Pampa of Argentina 

      Morras, Hector; Moretti, Lucas Martin (Springer, 2016)
      The Rolling Pampa is one of the several subregions of the large Pampa plains in central Argentina. The most extensive and representative soils in the area are Typic Argiudolls, together with a smaller proportion of Vertic ...

    • Nuevos aportes sobre la génesis y taxonomía de los suelos en el nordeste de Santiago del Estero 

      Moretti, Lucas Martin; Vizgarra, Lidia Amanda; Rodriguez, Dario Martin; Schulz, Guillermo; Paladino, Ileana Ruth; Morras, Hector (Asociación Geológica Argentina, 2017-08-07)
      Se presenta aquí una contribución al estudio de la génesis y la clasificación taxonómica de los suelos del noreste de Santiago del Estero. Para tal fin se realizó un mapa geomorfológico y se seleccionaron dos perfiles, uno ...

    • Polygenic vertisols and "Hidden" vertisols of the Paraná River Basin Argentina 

      Morras, Hector; Bressan, Emiliano Miguel; Angelini, Marcos Esteban; Tenti Vuegen, Leonardo Mauricio; Moretti, Lucas Martin; Rodriguez, Dario Martin; Schulz, Guillermo (Springer, 2023-01)
      Vertisols and soils with vertic properties occupy considerable areas in the east of the Pampa Region. Many of thèse Vertisols have particular features that dif- ferentiate them from most of the Vertisols in the world. In ...

    • Soils of the Chaco Region 

      Moretti, Lucas Martin; Morras, Hector; Pereyra, Fernando X.; Schulz, Guillermo (Springer, 2019)
      The Argentinian Chaco region belongs to an extensive ecoregion called “Great Chaco”, characterized by ample plains of fluvial aggradation and linked to the formation of large alluvial fans. The climate is semi-arid to ...

    • Suelos de la Región Pampeana. Procesos de formación 

      Imbellone, Perla Amanda; Gimenez, Jorge Eloy; Panigatti, Jose Luis (Ediciones INTA, 2010)
      En cada capítulo se describe la génesis de diferentes procesos como melanización, ilimerización, hidromorfismo, entre otros. Incluye fundamento teórico, evolución de los suelos , principales características morfológicas, ...
