Nitrogen

Monofertilizers

Nitrogen (N) is the most important plant nutrient. Its content in the plant ranges from 0.5 to 5% by weight of dry matter. It is a part of such important compounds as amino acids, proteins, vitamins, alkaloids, nucleic acids, pigments (chlorophyll), enzymes, glycosides, etc. Proteins contain from 15 to 17.5% of nitrogen. The fact that nitrogen is included in nucleic acids, which play a crucial role in metabolism and are carriers of hereditary (genetic) information, is enough to assess the significance of nitrogen in the plant life. Nitrogen not only participates in the flow of vital processes, but also determines the very possibility of the existence of life. Equally important is the fact that nitrogen is a part of chlorophyll, through which the photosynthesis process is performed. In addition to nitrogen, the chlorophyll molecule contains carbon, hydrogen and oxygen, but nitrogen forms a complex compound with magnesium, thanks to which photosynthesis takes place. In terms of chemistry, nitrogen in a plant is represented by several classes of
compounds: primary, secondary, tertiary and quaternary amines, amino acids, amides, porphyrins. In fertilizers, this element is most often present in nitrate (NO3-), ammonium (NH4+) and amide (-NH2) forms. Nitrate form is the most accessible for plants: through a series of transformations it transforms into ammonium and is involved in metabolic processes. The amide form (urea nitrogen) shows maximum efficiency in foliar application.
