Nitrogen gas makes up 78% of Earth’s atmosphere ... which moves the mineral from an area of low concentration in the soil to an area of high concentration, against a concentration gradient ...

This is when bacteria in the soil convert the nitrate back into nitrogen gas which then gets released back into the atmosphere.

In most gardens, nitrogen is nearly always the nutrient plants need. By virtue of the nitrogen cycle, microbes in the soil can decompose organic nitrogen from organic matter and crop residues and ...

Carbon cycle–climate feedbacks are expected to diminish the size of the terrestrial carbon sink over the next century. Model simulations suggest that nitrogen availability is likely to play a ...
