摘要：The fertilizer management is one of the greatest challenges of agriculture in the 21st century.The growing demand for food, along with the similar amount of arable land, creates the necessity of increasing the crop yields in a given area.Due to the fact that the production and use of mineral fertilizers often influence the environment in a negative way, for many years more attention has been paid to natural and organic fertilizers.Their advantage is the transfer of not only organic matter but also nutrients to the soil.In connection with the structural changes in agriculture, the production of natural fertilizers, especially manure decreases, but at the same time, the production of other organic fertilizers, e.g.composts or biochar increases.The aim of the work was to present the possibility of using biochar in the production of organic fertilizers.Moreover, the project concept for obtaining an organic fertilizer containing biochar and its application in the processes of biological transformation of waste was presented.
