Biochar is a material with high carbon content produced as a result of thermochemical transformation processes of organic material. In addition to the industrial and environmental uses of biochar, it is used as a soil conditioner in problematic soils in the agricultural sector. In this study, the effects of biochar on some soil physical properties, moisture changes in soil and plants, and soil temperature were investigated. In detailed literature reviews, it was determined that biochar application has positive effects at the some of the soil physical properties such as; soil bulk density, porosity, hydraulic conductivity, aggregate stability, shear and tensile strength, moisture content of the plant and soil. In these studies, concluded that the effects of biochar on soil properties vary depending on the production technology of biochar and some physical properties of biochar. The factors such as pyrolysis temperature, raw material type, aggregate diameter used in the production phase have changed the effect levels of biochar on the soil. In addition, it was determined that most of the studies on the subject were carried out in a laboratory or greenhouse for a maximum of 2 years. Therefore, it was concluded that field experiments should be conducted that determine the long-term effects of biochar on the soil. It is also an important subject in researching the effectiveness of the methods to be used to mix biochar with soil. [ABSTRACT FROM AUTHOR]
