In this study, we examined the ecology of the microbial nitrogen (N) cycle in bulk soil samples from a chronosequence of the Damma glacier, Switzerland. Major processes of the N cycle were ...

The Nitrogen Cycle Let’s begin our discussion of the N cycle in a typical grain crop rotation (corn, wheat, double-crop beans) by considering the plant residue left on the field surface after harvest.

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

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 ...

If corn was ever jealous of soybean’s relationship with nitrogen-fixing bacteria, advancements in gene editing could one day ...
