Nitrogen fixation is a process by which nitrogen in the Earth's atmosphere is converted into ammonia or other molecules available to living organisms. Atmospheric nitrogen or molecular dinitrogen is relatively inert: it does not easily react with other chemicals to form new compounds. The fixation process frees nitrogen atoms from their triply bonded diatomic form, Nâ¡N, to be used in other ways. Nitrogen fixation is essential for some forms of life because inorganic nitrogen compounds are ...
The cost of professional installation will depend partially on the size of your fence. Professional installers usually charge more for smaller fences to compensate for the extra travel and set-up time.
