    • Revisiting the relationship between nitrogen nutrition index and yield across major species 

      Rodriguez, Ignacio; Lacasa, Josefina; van Versendaal, Emmanuela; Lemaire, Gilles; Belanger, Gilles; Jégo, Guillaume; Sandaña, Patricio; Soratto, Rogério; Djalovic, Ivica; Ata-Ul-Karim, Syed Tahir; Reussi Calvo, Nahuel Ignacio; Giletto, Claudia Marcela; Zhao, Ben; Ciampitti, Ignacio (Elsevier, 2024-03)
      Crop nitrogen (N) fertilization diagnoses via the N nutrition index (NNI)-yield relationship have been tested for several crop species, but a cross-species comparison of that relationship has not been performed yet. This ...

    • Shoot- and tuber-based critical nitrogen dilution curves for the prediction of the N status in potato 

      Giletto, Claudia; Reussi Calvo, Nahuel Ignacio; Sandaña, Patricio; Echeverria, Hernan Eduardo; Bélanger, Gilles (Elsevier, 2020-09)
      Critical nitrogen (N) dilution curves describe the critical N concentration in plant tissues during crop growth and they are used to estimate the N nutriton status of whole plants in potato. Little is known, however, about ...

    • The effect of agriculture on topsoil carbon stocks is controlled by land use, climate, and soil properties in the Argentinean Pampas 

      Wyngaard, Nicolás; Crespo, Cecilia; Angelini, Hernán Pablo; Eyherabide, Mercedes; Larrea, Gaston Emiliano; Reussi Calvo, Nahuel Ignacio; Carciocchi, Walter Daniel; Sainz Rozas, Hernan Rene (Elsevier, 2022-05)
      The conversion of native grasslands into croplands with a high frequency of soybean (Glycine max L.) in crop rotations has diminished soil organic carbon (SOC) stocks in the Argentinean Pampas. The aims of our study were ...

    • Uso del índice de verdor para determinar la dosis optima económica de nitrógeno en maíz 

      Sainz Rozas, Hernan Rene; Reussi Calvo, Nahuel Ignacio; Barbieri, Pablo (Asociación Argentina de la Ciencia del Suelo, 2019-06)
      En regiones con excesos hídricos al comienzo de la estación de crecimiento, la aplicación de nitrógeno (N) en estadíos tempranos del maíz no es la mejor estrategia para maximizar la eficiencia de uso de dicho nutriente. ...
