    • A systems-level yield gap assessment of maize-soybean rotation under high- and low-management inputs in the Western US Corn Belt using APSIM 

      Balboa, Guillermo R.; Archontoulis, Sotirios; Salvagiotti, Fernando; Garcia, Fernando O.; Stewart, W.M.; Francisco, Eros Artur Bohac; Vara Prasad, P.V.; Ciampitti, Ignacio A. (Elsevier, 2019-08)
      Quantifying yield gaps (potential minus actual yield) and identifying management practices to close those gaps is critical for sustaining high-yielding production systems. The objectives of this study were to: 1) calibrate ...

    • Estimating nitrogen, phosphorus, potassium, and sulfur uptake and requirement in soybean 

      Salvagiotti, Fernando; Magnano, Luciana; Ortez, Osler; Enrico, Juan Martin; Barraco, Miriam Raquel; Barbagelata, Pedro Anibal; Condori, Alicia Adelina; Di Mauro, Guido; Manlla, Amalia Graciela; Rotundo, Jose Luis; García, Fernando O.; Ferrari, Manuel Carlos; Gudelj, Vicente Jorge; Ciampitti, Ignacio A. (Elsevier, 2021-07)
      Estimation of crop nutrient demand, seed nutrient removal, and nutrient use efficiency (yield to nutrient uptake ratio) are crucial for pursuing both balanced nutrition and more sustainable farming systems. However, the ...

    • Exploring nitrogen limitation for historical and modern soybean genotypes 

      Ortez, O.A.; Salvagiotti, Fernando; Enrico, Juan Martin; Prasad, P.V.V.; Armstrong, P.; Ciampitti, Ignacio A. (American Society of Agronomy, 2018-10)
      The United States (USA) and Argentina (ARG) account for over 50% of the global soybean [Glycine max (L.) Merr.] production. Soybean N demand is partially met (50–60%) by the biological nitrogen fixation (BNF) process; ...

    • Intensive Soybean Management : an Integrated Systems Approach 

      Balboa, Guillermo R.; Stewart, Mike; Salvagiotti, Fernando; García, Fernando O.; Francisco, Eros Artur Bohac; Ciampitti, Ignacio A. (2017)
      Ecological intensification impacted soybean yield, biomass and N uptake. Narrow row spacing, high seeding rate, other best production practices, and balanced nutrition increased partitioning effi ciency for biomass, measured ...

    • New insights into soybean biological nitrogen fixation 

      Ciampitti, Ignacio A.; Salvagiotti, Fernando (American Society of Agronomy, 2018-08)
      Soybean biological N2 fixation (BNF) relationships with fertilizer N and yield response have been comprehensively reviewed in the scientific literature. However, the study of the N-gap between N uptake and N supplied by ...

    • Nitrogen and sulfur interaction on nutrient use efficiencies and diagnostic tools in maize 

      Carciochi, Walter Daniel; Salvagiotti, Fernando; Pagani, Agustin; Reussi Calvo, Nahuel Ignacio; Eyherabide, Mercedes; Sainz Rozas, Hernan Rene; Ciampitti, Ignacio A. (Elsevier, 2020-05)
      Nitrogen (N) and sulfur (S) critical dilution curves and the N:S stoichiometry are useful tools for evaluating nutrient status in maize (Zea mays L.). Nutrient supply for both N and S impact plant nutrient uptake, consequently ...

    • Nutrient partitioning and stoichiometry in soybean: A synthesis-analysis 

      Tamagno, S.; Balboa, Guillermo R.; Assefa, Yared; Kovács, P.; Casteel, S.N.; Salvagiotti, Fernando; García, Fernando O.; Stewart, W.M.; Ciampitti, Ignacio A. (2017-01)
      On-farm attainable soybean yields are primarily limited by nutrient and water supply. High-yielding soybeans is related to high nutrient uptake. A proposed theoretical framework underpinning yield formation includes plant ...

    • Soja de alto rendimiento: ganancia genética y limitación por nitrógeno 

      Ortez, O.A.; Salvagiotti, Fernando; Enrico, Juan Martin; Ciampitti, Ignacio A. (IPNI, 2017-12)
      La mejora genética del rendimiento de soja desde la década de 1980 hasta la del 2010 representó 30% promediando en sitios ubicados en los Estados Unidos y Argentina. Para todas las pocas de liberación, la fertilización ...

    • Soybean nitrogen sources and demand during the seed-filling period 

      Ortez, O.A.; Tamagno, S.; Salvagiotti, Fernando; Prasad, P.V.V.; Ciampitti, Ignacio A. (American Society of Agronomy, 2019-05)
      Soybean [Glycine max (L.) Merr.] seed N demand not met by biological N fixation is fulfilled by N remobilization from vegetative plant organs and N uptake from soil sources during the seed-filling period (SFP), herein ...
