The data of structural carbohydrates content in the grasses of sowing alfalfa for 2‒4 years of life cultivated on agro-peat soils of the Belarusian Polesye was presented. It was found that in the dry mass of lucerne the content of neutral detergent fiber, acid-detergent fiber and hemicellulose was in the range of 36,8‒59,3%, 19,7‒36,5% and 16,4‒22,9 %, respectively, depending on the year of use and experience options. The content of non-structural carbohydrates by years of life was 14,8‒38,4%.
