A doubling in global food demand projected for the next 50 years poses huge challenges for
the sustainability both of food production and of terrestrial and aquatic ecosystems and the …

Arboriculture must maintain acceptable fruit production levels while preserving natural
resources. This duality can be analyzed with the concept of ecosystem service. We reviewed …

Nitrogen is a key element controlling the species composition, diversity, dynamics, and
functioning of many terrestrial, freshwater, and marine ecosystems. Many of the original …

Expansion and intensification of cultivation are among the predominant global changes of
this century. Intensification of agriculture by use of high-yielding crop varieties, fertilization …

Tropospheric ozone, also a greenhouse gas (Lammel and Graßl 1995), is a threat to human
health and it decreases crop yield (NAS 1991). Although they have different atmospheric …

Bacterial Biogeochemistry, Third Edition focuses on bacterial metabolism and its relevance
to the environment, including the decomposition of soil, food chains, nitrogen fixation …

Emissions of nitrous oxide from intensively managed agricultural fields were measured over
3 years. Exponential increases in flux occurred with increasing soil water‐filled pore space …

Nitrogen fertilization is a substantial source of nitrogen-containing trace gases that have
both regional and global consequences. In the intensive wheat systems of Mexico, typical …

Conventional agriculture has improved in crop yield but at large costs to the environment,
particularly off-site pollution from mineral N fertilizers. In response to environmental …

Over 60 published papers reporting field measurements of emissions of nitric oxide (NO)
from soil are reviewed, and over 100 annual estimates of NO emissions were made for …
