Biological nitrogen fixation in field pea and vetch: Response to inoculation and residual effect on maize in the Pampean region
(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. The aims of this study were to i) quantify ... -
Biological nitrogen fixation in soybean in Argentina: relationships with crop, soil, and meteorological factors
(2015-07)Aims: This study aims to (i) asses the contribution of biological N fixation (%Ndfa) in the soybean production area of Argentina, (ii) build a model for predicting %Ndfa using crop, soil, and meteorological variables, and ... -
Cell remodeling and subtilase gene expression in the actinorhizal plant Discaria trinervis highlight host orchestration of intercellular Frankia colonization
(2018-08)Nitrogen‐fixing filamentous Frankia colonize the root tissues of its actinorhizal host Discaria trinervis via an exclusively intercellular pathway. Here we present studies aimed at uncovering mechanisms associated with ... -
Contribución de la fijación biológica de nitrógeno en vicia y arveja
(EEA Oliveros, INTA, 2020)En Argentina el cultivo de soja (Glycine max L) predomina en los sistemas agrícolas, en la mayor parte de los casos como monocultivo (Caviglia y Andrade, 2010) y con largos periodos de barbecho descubierto, poniendo en ... -
Contribution of different sources and origins of nitrogen in above- and below-ground structures to the partial nitrogen balance in soybean
(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 ... -
Evaluation of bradyrhizobia strains isolated from field-grown soybean plants in Argentina as improved inoculants
(Springer, 2010-09-22)Bradyrhizobium strains were isolated from nodules obtained from field-grown soybean plants sampled in 12 soybean production locations in Argentina. These fields had been annually cropped with soybean and did not show ... -
Exploring nitrogen limitation for historical and modern soybean genotypes
(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; ... -
Exploring the Intrinsic Limits of Nitrogenase Transfer from Bacteria to Eukaryotes
(Springer, 2013-08)Biological nitrogen fixation is widespread among the Eubacteria and Archae domains but completely absent in eukaryotes. The lack of lateral transfer of nitrogen-fixation genes from prokaryotes to eukaryotes has been partially ... -
Feasibility of lowering soybean planting density without compromising nitrogen fixation and yield
(American Society of Agronomy, 2014)Adjusting soybean [Glycine max (L.) Merrill] density can be critical to reduce inter-plant competition for water, nutrients, and sunlight, and to increase intercepted radiation, photosynthesis, and biomass production. The ... -
Improvement of soybean grain nutritional quality under foliar inoculation with Azospirillum brasilense strain Az39
(2018-07)Legumes depend on biological nitrogen fixation through symbiosis with rhizobia to meet their nitrogen requirements. Certain plant growth promoting rizobacteria such as Azospirillum may cooperate in the establishment and ... -
Major cereal crops benefit from biological nitrogen fixation when inoculated with the nitrogen-fixing bacterium Pseudomonas protegens Pf-5 X940
(2016)A main goal of biological nitrogen fixation research has been to expand the nitrogen-fixing ability to major cereal crops. In this work, we demonstrate the use of the efficient nitrogen-fixing rhizobacterium Pseudomonas ... -
New insights into soybean biological nitrogen fixation
(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 balance in a plant-soil system under different cover crop-soybean cropping in Argentina
(2018-10-10)Cover crops (CC) provide many benefits for the soil and the following crop but their effects on nitrogen (N) release and balance in continuous no-tillage soybean (Glycine max L. Merr.) production are little known. Estimation ... -
Nutrición biológica nitrogenada en maíz : ¿Cuánto debería fijar por planta para igualar en porcentaje a la soja?
(HA Ediciones, 2023-07-19)La soja es una planta de la familia de las Leguminosas de gran importancia económica y nutricional en todo el mundo. La disponibilidad de nitrógeno (N) es uno de los factores clave que influyen en el crecimiento y el ... -
Nutritional and environmental effects on biological nitrogen fixation in soybean: a meta-analysis
(Elsevier, 2019-07)Biological N2 fixation (BNF) and mineral soil absorption are complementary N sources for soybean growth. BNF is sensitive to nutrient and environmental conditions, though a comprehensive synthesis of the studies underlying ... -
Relative importance of biological nitrogen fixation and mineral uptake in high yielding soybean cultivars
(2017-09)Backgrounds and aims: Soybean yield depends on total N uptake, N use efficiency, and harvest index. Nitrogen uptake relays on biological fixation (BNF) and soil absorption. Usually, BNF is considered a yield-related process. ... -
Soybean nitrogen sources and demand during the seed-filling period
(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 ...
