Methods of Application and Incorporation of the Biochar into Soil

Biochar from thermochemical transformation processes of biomass is used as a potential soil conditioner for problem soil. Biochar application into the soil cause positive improvement in the physical, chemical and biological soil quality criteria. Biochar causes a decrease in soil bulk density and increase the soil porosity. In addition to this, biochar application increases the soil aggregate stabilization and amount of the water stored in plants. Biochar has positive effects on the carbon content of the soil. Carbon originating from biochar remains in the lower layers of the soil for many years without deteriorating its properties. Biochar reduces CO2 emission from soil to atmosphere and prevents global warming caused by greenhouse gases in atmosphere. It must be mixed into the soil layer using appropriate methods to obtain these benefits from biochar. In order to mix the biochar into the soil substrates homogeneously, the rotovators and discarows are used. In addition, biochar can be mixed with solid or liquid animal manure by use fertilizer spreader machines and into the soil. Thanks to this method, the benefits of biochar increase to the maximum level.
