    • Azufre en trigo: ¿fertilizamos? 

      Mateos, Julián; Carciochi, Walter; Divito, Guillermo; Mateos Inchauspe, Facundo; Sainz Rozas, Hernan Rene (Estación Experimental Agropecuaria Balcarce, INTA, 2020-05)
      Ensayos realizados en el sudeste bonaerense indicaron que hay situaciones en las que es necesario fertilizar con azufre (S) en trigo. Para eso, es necesario contar con métodos que permitan detectar deficiencias de este ...

    • A Comparison of indexes to estimate corn S uptake and S mineralization in the field 

      Carciochi, Walter Daniel; Wyngaard, Nicolás; Divito, Guillermo Adrián; Cabrera, Miguel L.; Reussi Calvo, Nahuel Ignacio; Echeverria, Hernan Eduardo (2018-04)
      The development of simple predictors of sulfur (S) mineralization and its correlation with field-derived data may help improving corn S availability diagnosis. The objectives of this study were (1) to compare methods to ...

    • Diagnosis of sulfur availability for corn based on soil analysis 

      Carciochi, Walter Daniel; Wingaard, Nicolás; Divito, Guillermo Adrián; Reussi Calvo, Nahuel Ignacio; Cabrera, Miguel; Echeverria, Hernan Eduardo (Springer Berlin Heidelberg, 2016-10)
      Different edaphic properties were evaluated to diagnose soil sulfur (S) availability for corn in 15 field experiments as follows: (a) soil sulfate (SO4 −2-S) content at sowing at 0–20 cm and 0–60 cm depths [Sini(0–20) and ...

    • 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). ...

    • N and S concentration and stoichiometry in soybean during vegetative growth: Dynamics of indices for diagnosing the S status 

      Divito, Guillermo Adrián; Echeverria, Hernan Eduardo; Andrade, Fernando Hector; Sadras, Victor Oscar (Elsevier, 2016-11)
      Information regarding the pattern of sulphur (S) accumulation in shoots is scarce for field crops and few comprehensive analysis were performed on N:S stoichiometry. Particularly, the need to study the patterns of uptake, ...

    • Prognosis and diagnosis of sulfur status in maize by plant analysis 

      Carciochi, Walter; Reussi Calvo, Nahuel Ignacio; Wyngaard, Nicolás; Divito, Guillermo; Eyherabide, Mercedes; Echeverria, Hernan Eduardo (Elsevier, 2019-05)
      The analysis of sulfur concentration (SC) and nitrogen to S ratio (N/S) in plant tissue are some of the suggested tools to evaluate S deficiency in maize (Zea mays L.). However, the convenience of one over the other and ...

    • Sulfur affects root growth and improves nitrogen recovery and internal efficiency in wheat 

      Carciocchi, Walter Daniel; Divito, Guillermo Adrián; Fernández, Lucrecia A.; Echeverria, Hernan Eduardo (2017)
      Wheat plants were cultivated in pots with the objective of evaluate the effect of two sulfurrates (+S and -S) on i) shoot growth, S and nitrogen uptake and nitrogen use efficiency(NUE) and ii) root growth and architecture ...

    • Sulfur Mineralization: A Key Process for Diagnosing Its Deficiency in Wheat 

      Carciochi, Walter D.; Mateos, Julian; Divito, Guillermo; Mateos Inchauspe, Facundo; Sainz Rozas, Hernan Rene (Soil Science Society of America, 2019-09)
      Core Ideas: A simplified balance was used to calculate apparent S mineralization in wheat. Apparent S mineralization predicted relative wheat grain yield. Sulfate‐S before sowing combined with particulate organic C diagnosed ...
