• Antifungal and toxicological evaluation of the alkaloids fraction from Neltuma nigra leaves 

      Sequin, Christian J.; Appelhans, Stefania Carolina; Heis, Magalí S.; Torrent, Walter A.; Trossero, Julia A.; Catalan, Cesar Atilio Nazareno; Sampietro, Diego Alejandro; Aceñolaza, Pablo Gilberto (Elsevier, 2023-11)
      The use of synthetic fungicides for control soybean crop diseases has been cuestionated because of its impacts on human health and the environment. This work evaluated the composition, antifungal activity and toxicity of ...
    • Assessing soil P fractions changes with long‐term phosphorus fertilization related to crop yield of soybean and maize 

      Appelhans, Stefania Carolina; Barbagelata, Pedro Anibal; Melchiori, Ricardo Jose; Gutierrez Boem, Flavio Hernán (Wiley, 2020-02)
      Long-term P fertilization increases soil phosphorus (P) labile fractions, which can be associated with crop P uptake and grain yield and are useful to improve fertilizer recommendations. Research aims were to evaluate in ...
    • Crop sequence and P fertilization effects on soil P fractions under no-tillage 

      Appelhans, Stefania Carolina; Novelli, Leonardo Esteban; Melchiori, Ricardo Jose; Gutierrez Boem, Flavio Hernán; Caviglia, Octavio (Springer, 2021-05-27)
      Increasing cropping intensity may affect phosphorus (P) recycling through crop residue inputs, which may differ in soils with different productivity, P adsorption capacity, and P fertilization level. In three crop sequences: ...
    • Does the fertilisation strategy affect the long-term legacy phosphorus dynamic? 

      Appelhans, Stefania Carolina; Novelli, Leonardo Esteban; Melchiori, Ricardo Jose; Barbagelata, Pedro Anibal (Elsevier, 2024-02)
      Phosphorus (P) imbalances in agricultural systems are a global problem because they have environmental and economic impacts, like eutrophication when there is a soil P surplus and low crop productivity in P deficient soils. ...
    • Is the lack of response of maize to fertilization in soils with low Bray1-p related to labile organic phosphorus? 

      Appelhans, Stefania Carolina; Barbagelata, Pedro Anibal; Melchiori, Ricardo Jose; Gutierrez Boem, Flavio Hernán (Springer, 2021-01-07)
      The usual soil test phosphorus (P) neglects the P supply from labile organic P (Po) fractions, which could explain the nonresponse of maize (Zea mays L.) in sites with soil P testing below the critical level. We aim to ...
    • Prácticas de manejo para mejorar la producción y calidad de trigo 

      Valentinuz, Oscar Rodolfo; Brassesco, Raul Francisco; Vallejos, Maximiliano; De Carli, Ricardo Armando; Behr, Enrique Federico; Maydana, Haydeé Cristina; Wouterlood, Natalia; Pautasso, Juan Manuel; Melchiori, Ricardo Jose; Maltese, Nicolás; Appelhans, Stefania Carolina (Estación Experimental Agropecuaria Paraná, INTA, 2017)
      El presente trabajo reporta resultados obtenidos en el marco del acuerdo de colaboración para evaluar efectos de distintas estrategias de fertilización nitrogenada en trigo sobre el rendimiento y calidad, acordado con CREA ...
    • Predicting soil test phosphorus decrease in non-P-fertilized conditions 

      Appelhans, Stefania Carolina; Carciochi, Walter Daniel; Correndo, Adrián A.; Gutierrez Boem, Flavio Hernán; Salvagiotti, Fernando; García, Fernando O.; Melchiori, Ricardo Jose; Barbagelata, Pedro Anibal; Ventimiglia, Luis Alberto; Ferraris, Gustavo Nestor; Vivas, Hugo Silverio; Caviglia, Octavio; Ciampitti, Ignacio A. (Wiley, 2020-02)
      Monitoring the availability of phosphorus (P) in soil under continuous cropping facilitates finding deficiency in crops and contributes to improving crop growth and nutrient management models. Soil P availability for crops ...

      Pereyra, M.V.; Maltese, Nicolás; Appelhans, Stefania Carolina; Melchiori, Ricardo Jose (2021)
      Este trabajo tuvo como objetivo determinar el efecto de la variabilidad espacial y temporal sobre el rendimiento de soja a nivel de planta y cultivo bajo condiciones productivas de siembra.
