Nitrogen fertilizers used in agriculture contribute significantly to global warming. A new breeding concept, specifically for wheat, could help reduce nitrogen fertilization. This holobiont principle ...

In the phosphorus cycle, phosphorus is circulated mainly through soil, rocks, water, and living organisms. Phosphorus is found organically in the form of the phosphate ion (PO43-).

What are nitrates? Nitrogen gas makes up 78% of Earth’s atmosphere and is an essential element in amino acids and proteins. However, plants and animals cannot use nitrogen gas directly.

But models of this nitrogen cycle are in need of a major update, a group of biogeochemists says. The researchers claim the models omit about 15 tera­grams of nitrogen produced by rock weathering ...

The major portion of the global nitrogen cycle occurs between vegetation and soil, only minor exchanges generally taking place with the atmosphere and the hydrosphere. Nitrogen conversions in soil are ...

This nitrogen cascade manifests in a variety of ways. Nitrogen oxides contribute to the production of ground-level ozone, or smog, which increases the risk of serious respiratory illness and ...
