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 ...

Of all of the elements necessary for tree growth, the one nutrient that is most often in short supply is nitrogen (N2). This is because nitrogen in its elemental form (N2) is a gas, which makes it ...
