Nitrogen is a mineral element that in the world of agriculture is essential for the growth and development of plants, when a plant for example grasses has the appropriate amounts of nitrogen improves some morphological characteristics of these as the seeding in species that are established in this way, it also influences the height of the plant. If, on the contrary, an insufficiency of this element is found, a yellowish color can be seen in the leaves and a plant with poor growth.

In agricultural agroecosystems it is important to take into account that, despite the importance of this nutritional element, there may be a deficiency of it because this element is not part of the parent material from which the soil originates, the largest percentage of nitrogen is available in the atmosphere and thus cannot be used by plants, in addition to the deficiency that may exist in the soils of this element, there is also the possibility of it being lost to the atmosphere through volatilization or by leaching due to the excess water that may exist at any given time.

For the aforementioned, it is important to mention that nitrogen can be fixed to the soil through a natural process carried out by some bacteria, some are freely in the soil and others perform symbiosis with the roots of some plants such as those belonging to the legume families, this element can also be obtained through a recycling of nutrients that is what we refer to, for example, the leaves of some trees that once they fall to the ground are decomposed by efficient microorganisms and mineralize this element so that it can be used by crops. Most of the processes of obtaining this element with the exception of the one obtained through industrialized processes obtaining synthetic nitrogen fertilizers such as urea.
