In addition, due to its low price and environmental protection, biochar has received more and more attention in dealing with soil nutrients, acidification, and heavy metals. In addition, since the raw materials of biochar are mainly agricultural waste, returning straw to the field has always been a straw treatment method advocated by the country.
