Biochar is a carbonaceous product of biomass pyrolysis under limited oxygen conditions. Due to the very good sorption properties material is used as a soil amendment. In recent years, much attention has been paid to biochar as a potential tool improving soil properties and fertility. The most important benefits of its use in agriculture is a significant increase of sorption capacity, reduced nutrient leaching, as well as slow release of macro- and microelements essential for plant growth, liming effect, increased water holding capacity, improved biological properties, resulting in an increase in crop yields. The aim of the study is to summarize the knowledge about the impact of biochar on soil environment, as well as identify areas and directions for future research on biochar application in soils impacted by human activities
