    • Changes in soil phosphorus (P) fractions and P bioavailability after 10 years of continuous P fertilization 

      Biassoni, María Micaela; Vivas, H.; Gutierrez Boem, Flavio Hernán; Salvagiotti, Fernando (Elsevier, 2023-08)
      Phosphorus fertilization modify soil P fractions differing in availability, but little is known about bioavailability of these pools for the crops when increasing P fertilizer rates in the medium term. Our objectives were ...

    • Contrasting effects of phosphorus and potassium deficiencies on leaf area development in maize 

      Arias Usandivaras, Luis María; Gutierrez Boem, Flavio Hernán; Salvagiotti, Fernando (Crop Science Society of America, 2018-10)
      Management of P and K in agricultural systems is similar, since both move mainly by diffusion in soil. In maize (Zea mays L.), radiation capture is a consequence primarily of leaf area formation and senescence, but little ...

    • 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 ...

    • N:P:S stoichiometry in grains and physiological attributes associated with grain yield in maize as affected by phosphorus and sulfur nutrition 

      Salvagiotti, Fernando; Prystupa, Pablo; Ferraris, Gustavo Nestor; Couretot, Lucrecia Alejandra; Magnano, Luciana; Dignani, Damian; Gutierrez Boem, Flavio Hernán (2017-03)
      Balanced nutrition is necessary to reduce yield gaps in maize. Simultaneous phosphorus (P) and sulfur (S) deficiencies may be present in soils, so a P × S interaction is expected. In maize, yield is closely related to grain ...

    • 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 ...
