The marine nitrogen cycle: new developments and global change

In general, the N cycle processes of fixation, mineralization and nitrification increase plant available N Denitrification, volatilization, immobilization, and

During the cycle, certain bacteria 'fix' atmospheric nitrogen into ammonia, which plants need in order to grow Other bacteria convert the
