Biological nitrogen fixation in field pea and vetch: Response to inoculation and residual effect on maize in the Pampean region
Enrico, Juan Martin; Piccinetti, Carlos Fabian; Barraco, Miriam Raquel; Agosti, Maria Belén; Eclesia, Roxana Paola; Salvagiotti, Fernando (Elsevier, 2020)Including legumes in winter, both as cover crop or for grain harvest, is recommended for avoiding long periods of bare fallow and supplying N for succeeding crops in the rotation.

Changes in soil phosphorus (P) fractions and P bioavailability after 10 years of continuous P fertilization
Biassoni, María Micaela; Vivas, Hugo; 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 ... -
Contribution of different sources and origins of nitrogen in above- and below-ground structures to the partial nitrogen balance in soybean
Kehoe, Esteban; Rubio, Gerardo; Salvagiotti, Fernando (Springer, 2022-04)Aims: Most studies that quantified the biological N fixation (BNF) and partial N balances of soybean have ignored the belowground structures. Our objectives were to evaluate the contribution of belowground structures to ... -
Does biological nitrogen fixation modify soybean nitrogen dilution curves?
Santachiara, Gabriel; Salvagiotti, Fernando; Gerde, José Arnaldo; Rotundo, José Luis (2018)Biological nitrogen fixation (BNF) in soybean [Glycine max (L.) Merr.] represents, on average, 60% of total nitrogen (N) uptake. Nitrogen dilution curves link aboveground crop N concentration (%N) to biomass accumulation (W). ... -
DTPA-extractable zinc threshold for wheat grain yield response to zinc fertilization in Mollisols
Martinez Cuesta, Nicolás; Carciochi, Walter; Salvagiotti, Fernando; Sainz Rozas, Hernan Rene; Wyngaard, Nicolás; Lopez De Sabando, Marcelo; Barbieri, Pablo (Wiley, 2021-06)Determining soil Zn thresholds for wheat (Triticum aestivum L.) is still challenging since soil Zn tests have been poorly calibrated. Therefore, this work aimed to determine, under field conditions, the DTPA-Zn critical ... -
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 ... -
Evaluating a hybrid soil temperature model in a corn-soybean agroecosystem and a tallgrass prairie in the Great plains
Song, Feng; Salvagiotti, Fernando; Schmer, M.R.; Wingeyer, Ana Beatriz; Weiss, Albert (University of Nebraska Press, 2010)Simulation models of soil-related biological processes usually require soil temperature data. Frequently these soil temperatures are simulated, and the soil temperature algorithms cannot be more complicated than the original ... -

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; ... -
