    • Agricultura de precisión: dosis variable de fósforo en soja (Glycine max (L.) Merr.) 

      Peralta, Nahuel Raúl; Trueba, Martín; Wyngaard, Nicolás; Córdoba, Mariano; Sallesses, Leonardo Fabian (Asociación Argentina de la Ciencia del Suelo, 2021-07)
      La agricultura de precisión (AP) permite delimitar zonas de manejo (ZM) que expresan diferente potencial de rendimiento. Los objetivos de esta investigación fueron: (l) Determinar la interacción entre las ZM y la fertilización ...
    • Can edaphic variables improve DTPA-Based zinc diagnosis in corn? 

      Barbieri, Pablo; Sainz Rozas, Hernan Rene; Wingaard, Nicolás; Eyherabide, Mercedes; Reussi Calvo, Nahuel Ignacio; Salvagiotti, Fernando; Correndo, Adrián A.; Barbagelata, Pedro Anibal; Espósito Goya, Gabriel P.; Colazo, Juan Cruz; Echeverria, Hernan Eduardo (2017-06-01)
      Current zinc (Zn) diagnostic methods for corn (Zea mays L.) are often based on soil DTPA (diethylenetriamine-pentaacetic acid) extractable Zn (DTPA-Zn). However, calibration of the DTPA-Zn test may be influenced by other ...
    • 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 ...
    • Determining Mehlich-3 and DTPA extractable soil zinc optimum economic threshold for maize 

      Martínez Cuesta, Nicolas; Wyngaard, Nicolás; Sainz Rozas, Hernan Rene; Reussi Calvo, Nahuel Ignacio; Carciochi, Walter; Eyherabide, Mercedes; Colazo, Juan Cruz; Barraco, Miriam Raquel; Guertal, Elizabeth; Barbieri, Pablo (Wiley, 2020-09-16)
      Maize (Zea mays L.) is one of the most susceptible crops to zinc (Zn) deficiency. However, in much of the world, soil Zn tests are poorly calibrated, and thus determining a critical soil test, level for Zn is challenging. ...
    • 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 ...
    • Effect of intensified cropping sequences on soil physical properties in contrasting environments 

      Crespo, Cecilia; Wyngaard, Nicolás; Sainz Rozas, Hernan Rene; Studdert, Guillermo; Barraco, Miriam Raquel; Gudelj, Vicente Jorge; Barbagelata, Pedro Anibal; Barbieri, Pablo (Elsevier, 2021-08-27)
      Soybean (Glycine max (L.) Merr.) monoculture contributes to soil degradation. Intensification of soybean-based sequences through polyculture, cover crops (CC), and crop fertilization can enhance soil physical quality and ...
    • Effect of the intensification of cropping sequences on soil organic carbon and its stratification ratio in contrasting environments 

      Crespo, Cecilia; Wyngaard, Nicolás; Sainz Rozas, Hernan Rene; Studdert, Guillermo; Barroco, Mirian; Gudelj, Vicente Jorge; Barbagelata, Pedro Anibal; Barbieri, Pablo (Elsevier, 2021-01-19)
      In environments where continuous agriculture leads to soil organic carbon (SOC) depletion, intensification practices (i.e. polyculture, cover crops (CC), and crop fertilization) have been suggested as strategies to improve ...
    • Effect of zinc application strategies on maize grain yield and zinc concentration in mollisols 

      Martinez Cuesta, Nicolás; Carciochi, Walter; Sainz Rozas, Hernan Rene; Salvagiotti, Fernando; Colazo, Juan Cruz; Wyngaard, Nicolás; Eyherabide, Mercedes; Ferraris, Gustavo Nestor; Barbieri, Pablo (Taylor and Francis, 2020-11-12)
      Maize (Zea mays L.) is highly susceptible to zinc (Zn) deficiency. Different application strategies (AS) can be utilized to improve grain yield (GY) and quality (Zn biofortification) by combining Zn fertilizer rate, source, ...
    • 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). ...
    • 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 ...
