Possible sources for biochar production in the south of the Russian Far East

\nThe study investigates the comparative analysis of biochar from vegetable raw materials and paper. The analysis revealed that biochar from the raw materials we studied showed that biochar has an alkaline reaction of the medium, which means it can be used on acidic soils. The study found that according to the content of nitrogen and phosphorus, the studied material can be used on soils as an organic fertilizer. In general, it can be said that the most effective fertilizer, according to preliminary estimates, will be biochar from Ahnfeltia tobuchiensis and a mixture of perennial grasses, due to the high content of nitrogen and phosphorus. The use of biochar from various raw materials sources can become the basis for climate projects and the creation of its own carbon markets in the agricultural sector of the Russian Federation.\n
