Answer:
Nitrogen fixation is a process that implies the transformation of the relatively non-reactive atmospheric N2 into its more reactive compounds (nitrates, nitrites, or ammonia). Why is nitrogen fixation important? Such reactive forms are suitable for crops and support their growth. About 90% of natural N fixation on our planet is biotic and occurs thanks to soil microorganisms. Abiotic natural inducers are lightning and UV rays. Alternatively, N can be fixed with electrical equipment or industrially.
