    • Changes in soil biological properties in different management and tyllage systems in petrocalcic argiudoll 

      Moreno, Maria Virginia; Biganzoli, Fernando; Casas, C.; Manso, Marina Lucrecia; Moreira, E.; Silvestro, Luciana Belén (Elsevier, 2020-12)
      We analyzed the effect of different tillage systems on soils under different land-use histories, on biological properties of soil during one year. The experiment was carried out at a Petrocalcic Argiudoll of Tres Arroyos ...

    • Cultivable soil fungi community response to agricultural management and tillage system on temperate soil 

      Moreno, Maria Virginia; Casas, C.; Biganzoli, Fernando; Manso, Marina Lucrecia; Silvestro, Luciana Belén; Moreira, E.; Stenglein, Sebastian Alberto (Elsevier, 2021-02)
      In agricultural soils, fungi constitute most of the total microbial biomass in the environment contributing with more than 50% of the soil biomass. The fungi should be considered as a link in the production not only by ...

    • Edaphic forms of phosphorus in no-tillage cropping sequences in the Argentine southern central Pampas 

      Suñer, Liliana; García, Ramiro; Galantini, Juan Alberto; Forjan, Horacio Jose; Paz Gonzalez, Antonio (2018-08)
      Agriculture significantly affects phosphorus (P) availability, thereby modifying P equilibrium. The objective of this study was to evaluate the effect of different crop sequences on the dynamics of soil P forms under no ...

    • Fracciones de carbono y nitrógeno del suelo y productividad del trigo en el sudeste bonaerense, Argntina 

      Landriscini, María Rosa; Galantini, Juan Alberto; Forjan, Horacio Jose; García, Ramiro Javier (Facultad de Ciencias Agrarias, Universidad Nacional de Rosario, 2020)
      El uso del suelo, las labranzas y las secuencias estivales, afectan la distribución y el contenido de carbono orgánico (CO), nitrógeno total (NT) y sus fracciones con diferente grado de labilidad. En la Chacra Experimental ...

    • Mixed cropping regimes promote the soil fungal community under zero tillage 

      Silvestro, Luciana Belén; Biganzoli, Fernando; Stenglein, Sebastian Alberto; Forjan, Horacio Jose; Manso, Marina Lucrecia; Moreno, Maria Virginia (2017-12)
      Fungi of yield soils represent a significant portion of the microbial biomass and reflect sensitivity to changes in the ecosystem. Our hypothesis was that crops included in cropping regimes under the zero tillage system ...

    • Modelling effective soil depth at field scale from soil sensors and geomorphometric indices 

      Castro Franco, Mauricio; Domenech, Marisa Beatriz; Costa, Jose Luis; Aparicio, Virginia Carolina (2017)
      The effective soil depth (ESD) affects both dynamic of hydrology and plant growth. In the southeast of Buenos Aires province, the presence of petrocalcic horizon constitutes a limitation to ESD. The aim of this study was ...

    • Occurrence and distribution of soil Fusarium species under wheat crop in zero tillage 

      Silvestro, Luciana Belén; Steinglein, Sebastian Alberto; Forjan, Horacio Jose; Dinolfo, María Inés; Arambarri, Angélica Margarita; Manso, Marina Lucrecia; Moreno, María Virginia (2013)
      The presence of Fusarium species in cultivated soils is commonly associated with plant debris and plant roots. Fusarium species are also soil saprophytes. The aim of this study was to examine the occurrence and distribution ...

    • A pedometric technique to delimitate soil-specific zones at field scale 

      Castro Franco, Mauricio; Córdoba, Mariano Augusto; Balzarini, Mónica Graciela; Costa, Jose Luis (2018-07)
      Delimitation of soil types within a farm field is key for site-specific crop management. An alternative to this, is to develop pedometric techniques that allow an efficient combination of soil survey information and ...

    • Sampling scheme optimization to map soil depth to petrocalcic horizon at field scale 

      Domenech, Marisa Beatriz; Castro Franco, Mauricio; Costa, Jose Luis; Amiotti, Nilda Mabel (2017-03-15)
      Soil depth has played a key role in the development of soil survey, implementation of soil-specific management and validation of hydrological models. Generally, soil depth at field scale is difficult to map due to complex ...
