Annotation: The dissertation examines and solves closely related problems that are rapidly emerging worldwide. In order to ensure sufficient efficiency of the food chain, constant intensity of agricultural activity is carried out and thus the aim is to ensure the highest production. However, the constant use of concentrated fertilizers (especially nitrogen) increases nitrogen losses due to evaporation and leaching from the soil, due to the overall air and water pollution. The work concentrates on advanced ideas, materials and technologies, proposes ways to enrich suspension and the most popular nitrogen fertilizers (urea) with bioactive substances for this purpose (microalgae) and thus prepares complex suspension and solid nitrogen fertilizers, arranged so that sufficient plant food supply can be used, but together with food and helps to preserve soil health. Also, in order to optimize the production process of such fertilizers, the granulation of urea enriched with microalgae in a drum granulator is simulated using the discrete element method and evaluated using parameters describing the quality of granulation.
