In current times of increasing weather extremes and climate change, there is a request for cheap and also high-quality agricultural products. It is important to fertilize soils and improve their physical and chemical properties to increase an agricultural production. To improve soil properties are used various organic materials, and biochar is one of them. Biochar, a product of thermal degradation of biomass, helps to improve the hydro-physical properties of the soil. It is produced from biomass by pyrolysis proce...

Biochar is a porous, carbon-rich material produced by heating of organic matter to temperatures between 300 пїЅC and 1000 пїЅC in an environment with limited or no oxygen. During the past decade, numerous articles focusing on the use of biochar have been published, but have shown inconsistent results. Reactions in the soil after the addition of biochar depend on the characteristics of biochar, soil, climate and soil-inhabiting organisms. However, due to high variability in the quality of biochar, its effects on so...
