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 ... -
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 ... -
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; ... -
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 ... -
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 ...
