Background The demand for estimates of biological nitrogen (N) fixation inputs in
agricultural systems is driven by the need to effectively manage the global N cycle. Scope …

Management of nitrogen (N) inputs into agricultural systems is of increasing interest due to
the intensive use of synthetic fertilizers in modern cash crop systems, which has caused …

During the past decade, soil and geochemists have adopted a variety of novel chemical–
analytical methods to explore the chemistry of soil organic N (N org). This chapter …

Background and aims Legume-brassica intercrops may help to reduce N fertilizer input. We
tested whether (i) intercropping with faba bean can improve N status of rapeseed, and (ii) …

Compounds released by mungbean roots potentially represent an enormous source of
nitrogen (N) and carbon (C) in mungbean-oat intercropping systems. In this study, an in situ …

Bud outgrowth is a key process in the elaboration of yield and visual quality in rose crops.
Although light intensity is well known to affect bud outgrowth, little is known on the …

Plant roots exude nitrogen (N)-containing compounds, which are assimilated by the
rhizobiome to maintain stoichiometric homeostasis. Various 15 N-tracing methods exist to …

Intercropping of legumes and cereals is an important management method for improving
yield stability, especially in organic farming systems. However, knowledge is restricted on …

Root exudation is considered to regulate the abundance of the microbial community. It may
vary both qualitatively and quantitatively in response to the environment in which the plant is …

Background and aims Crop species grown in a diversified crop rotation can influence soil N
dynamics to varying degrees due to differences in the quantity and quality of the residues …
