• Whats the function of Nitrogen (N) in plants

    Nitrogen comes in different forms, Ammonium, Nitrate and Urea Nitrogen with nitrate nitrogen being the most abundant with easy uptake and favors soil retention, unlike ammonium nitrogen which requires more oxygen to be metabolized in the roots of plants where it reacts with sugars. Urea nitrogen, on the other hand, is a waste form of nitrogen.
