Nitrogen Fertilizer

Fertilizers are applied in the agricultural sector to provide more essential nutrients to growing plants. The so-called «NPK» fertilizers provide such nutrients to plants with its three main components (N – nitrogen, P – phosphorous, K – potassium). In fertilizers, nitrogen is mainly provided in three forms: as ammonium nitrate (NH4NO3), ammonia (NH3), and urea (H2NCONH2). Due to the different physical and chemical properties, uptake and release kinetics, mixtures of the nitrogen-providing compounds are used. Using such mixtures reduces the problem of fertilizer burns on plants, caused by an excess of nitrogen.
