    • Soil organic carbon in cropping sequences with predominance of soya bean in the argentinean humid Pampas 

      Martinez, Juan Pablo; Crespo, Cecilia; Sainz Rozas, Hernan Rene; Echeverria, Hernan Eduardo; Studdert, Guillermo; Martinez, Fernando Gabriel; Cordone, Graciela; Barbieri, Pablo (Wiley, 2020-01)
      Soya bean (Glycine max (L.) Merr.) monoculture can lead to a decrease in labile fractions of soil organic carbon (SOC). This study sought to evaluate the effects of cover crops (CC), application of fertilizer, and crop ...

    • Soybean and wheat response to lime in no-till Argentinean mollisols 

      Barbieri, Pablo Andres; Echeverria, Hernan Eduardo; Sainz Rozas, Hernan Rene; Martínez, Juan Pablo (Elsevier, 2015-09)
      Crop production in Argentina has significantly increased over the past few years; this increase was consequence of better management practices which included P and N fertilization and, occasionally, S fertilization. Commonly ...

    • Soybean shows an attenuated nitrogen dilution curve irrespective of maturity group and sowing date 

      Divito, Guillermo Adrián; Echeverria, Hernan Eduardo; Andrade, Fernando Hector; Sadras, Victor Oscar (2016-02-01)
      It is generally accepted that the nitrogen (N) dilution curves relating shoot nitrogen concentration (%N) and shoot biomass (W) are similar among genotypes from the same species. However, differences in the pattern of ...

    • 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 ...

    • Sustainable intensification of agriculture improves soil nitrogen in the argentinean humid pampas 

      Martínez, Juan Pablo; Crespo, Cecilia; Cuervo, Matías; Echeverria, Hernan Eduardo; Martinez, Fernando; Cordone, Graciela; Barbieri, Pablo (American Society of Agronomy, 2022-03-31)
      In the Argentinean Humid Pampas, intensification practices like crop rotation, cover crops (CC) and fertilization can improve soil nitrogen (N) balance. This study aimed to assess how intensification practices affect soil ...

    • Use of a critical phosphorus dilution curve to improve potato crop nutritional management 

      Zamuner, Ester Cristina; Lloveras, Jaume; Echeverria, Hernan Eduardo (Springer, 2016-08)
      Plant diagnostic methods to determine P deficiencies need the definition of a critical concentration value which represents the minimum P concentration required to achieve maximum growth. The critical P concentration (Pc) ...

    • Water Availability and Row Spacing Effects on Nitrogen Use Efficiency in No-Till Maize 

      Barbieri, Pablo; Echeverria, Hernan Eduardo; Sainz Rozas, Hernan Rene (Scholars Direct, 2022-06-08)
      Reduced row spacing has shown to increase nitrogen use efficiency (NUE) in no-till irrigated maize; however available information in rainfed conditions is scarce. The objective was to analyze row spacing effects on NUE ...
