Background We collated estimates of the percentage of legume N derived from atmospheric
N 2 (% Ndfa) for 14 major grain legumes and then analysed and aggregated the data to …

Nitrogen (N) fertilizers are one of the most expensive inputs in agricultural settings.
Additionally, the loss of N increases costs, contributes to soil acidification, and causes off …

This open access book is an outcome of the collaboration between the Soil and Water
Management & Crop Nutrition Section, Joint FAO/IAEA Division of Nuclear Techniques in …

Favorable climate and soils for rainfed crop production, together with a relatively low
population density, results in 70–90% of Argentina grain production being exported. No …

Core Ideas As N2 fixation (%) increased, seed production per N2 fixation decreased. The N‐
gap between crop N uptake and N supplied by N2 fixation rose when contribution from …

Background The co-inoculation of soybean with Bradyrhizobium and other plant growth-
promoting rhizobacteria (PGPR) is considered a promising technology. However, there has …

Legumes rely on soil mineral nitrogen (N) and biological N fixation (BNF). The interplay
between these two sources is biologically interesting and agronomically relevant as the crop …

Core Ideas Soybean seed inoculation with Bradyrhizobium japonicum enhances grain
production. Greater inoculation response happens in Argentinean sites than in the United …

The performance of the soybean (Glycine max) inoculated with Bradyrhizobium is influenced
by cropping history. However, re-inoculation with elite strains of Bradyrhizobium generally …

Biological N 2 fixation (BNF) and mineral soil absorption are complementary N sources for
soybean growth. BNF is sensitive to nutrient and environmental conditions, though a …
