In their natural environment, plants are part of a rich ecosystem including numerous and
diverse microorganisms in the soil. It has been long recognized that some of these microbes …

The supply of nitrogen commonly limits plant production in boreal forests and also affects
species composition and ecosystem functions other than plant growth. These interrelations …

Crop production has a large impact on the nitrogen (N) cycle, with consequences to climate,
environment, and public health. Designing better N management will require indicators that …

The literature on nitrogen (N) form effects on plants at different stages of their development
has been critically reviewed, assessing the possible mechanisms of these effects. In …

Nitrogen (N) is an essential but generally limiting nutrient for biological systems.
Development of the Haber-Bosch industrial process for ammonia synthesis helped to relieve …

Nitrogen nutrition in plants is a key determinant in crop productivity. The availability of
nitrogen nutrients in the soil, both inorganic (nitrate and ammonium) and organic (urea and …

Fungi play important roles as decomposers, plant symbionts and pathogens in soils. The
structure of fungal communities in the rhizosphere is the result of complex interactions …

Background For more than a century, crop N nutrition research has primarily focused on
inorganic N (IN) dynamics, building the traditional model that agricultural plants …

Nitrogen (N) deposition has rapidly increased and is influencing forest ecosystem processes
and functions on a global scale. Understanding process-specific N transformations, ie, gross …

More than half of the applied conventional fertiliser nitrogen (N) in crop** systems can be
lost to the environment, resulting in water and air pollution. Farming systems that ensure …
