Hemp (cannabis sativa l.) Is an effective carbon-depositing crop

Résumé fourni par la source

The article presents the results of a quantitative assessment of carbon deposition by sowing hemp (Cannabis sativa L.). Field studies were conducted in Khabibrakhmanov Peasant Farm Enterprise (Republic of Bashkortostan), the carbon content in plant biomass was determined by the CN 802 analyzer. It was found that cannabis crops form 7.87 t/ha aboveground biomass at the end of the growing season, including stems – 6.40 t/ha (81.3% of the aboveground mass), inflorescences – 0.77 t/ha (9.8% of the aboveground mass), seeds - 0.70 t/ha (8.9% of the aboveground mass), and roots - 1.02 t/ha. Of the total biomass, 8.19 t/ha is preserved. Sowing captures a relatively large amount of carbon dioxide from the atmosphere (14.78 t/ha) and, accordingly, carbon (4.03 t/ha). The effectiveness of cannabis in terms of decarbonization mainly consists in the conservation of a significant amount of accumulated carbon (91%) for a long time into long-term products and into the soil. The cultivation of hemp in carbon farms is recommended to reduce the carbon footprint and sell carbon units.
