Защитные лесные насаждения в условиях степной зоны выполняют важную роль в стабилизации агроландшафтов, влияя на водный режим, гумусообразование и биогеохимический цикл почв. Однако вопросы их влияния на содержание углерода и азота в чернозёмах остаются недостаточно изученными.</p></sec><sec><title>Материал и методика</title><p>Материал и методика. Исследования проведены в ГПЗ «Каменная степь» по трансекте, заложенной через лесополосу и прилегающие пашни. Определяли содержание общего углерода и азота в почвенном профиле и их пространственное распределение в зависимости от рельефа и экспозиции склонов.</p></sec><sec><title>Результаты</title><p>Результаты. Показано, что лесополосы способствуют интенсивному накоплению органического вещества и формированию сильно гумусированных разновидностей чернозёмов. Среднее содержание общего углерода и азота под древесной растительностью достоверно превышает их уровень в агрочернозёмах. В пашнях отмечается усиленная минерализация органического вещества, вынос элементов с урожаем и деградация почв до среднегумусированных типов. Пространственное распределение углерода и азота определяется не только землепользованием, но и микрорельефом, направлением доминирующих ветров и условиями снегозадержания.</p></sec><sec><title>Заключение</title><p>Заключение. Защитные лесные насаждения в агроландшафте являются ключевым фактором поддержания плодородия чернозёмов и повышения их экологической устойчивости. Полученные результаты подчеркивают важность сохранения и расширения системы лесополос как элемента устойчивого землепользования.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. Forest shelterbelts in the steppe zone play a crucial role in stabilizing agrolandscapes by influencing the water regime, humus formation, and the biogeochemical cycle of soils. However, their impact on the carbon and nitrogen content of Chernozems remains insufficiently studied.</p></sec><sec><title>Methodology</title><p>Methodology. The research was conducted in the Kamennaya Steppe Nature Reserve along a transect crossing a forest shelterbelt and adjacent arable fields. Total carbon and nitrogen contents were determined within the soil profile, as well as their spatial distribution in relation to topography and slope exposure.</p></sec><sec><title>Results</title><p>Results. The results show that forest shelterbelts promote intensive organic matter accumulation and the development of highly humus-enriched Chernozems. Mean total carbon and nitrogen contents under forest vegetation significantly exceeded their levels in AgroChernozems. In contrast, arable soils were characterized by enhanced mineralization of organic matter, nutrient removal with crop harvests, and degradation to moderately humus-enriched types. The spatial distribution of carbon and nitrogen was influenced not only by land use but also by microrelief, prevailing wind directions, and snow accumulation conditions. Forest shelterbelts in agrolandscapes represent a key factor in maintaining the fertility of Chernozems and enhancing their ecological stability.</p></sec><sec><title>Conclusion</title><p>Conclusion. The findings emphasize the importance of preserving and expanding forest shelterbelt systems as an element of sustainable land use.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>лесополосы</kwd><kwd>черноземы</kwd><kwd>общий углерод</kwd><kwd>общий азот</kwd><kwd>трансекта</kwd></kwd-group><kwd-group xml:lang="en"><kwd>shelterbelts</kwd><kwd>chernozems</kwd><kwd>total carbon</kwd><kwd>total nitrogen</kwd><kwd>transect</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена в рамках государственного задания Министерства науки и высшего образования Российской Федерации № 1025032000060-3-1.5.1 "Биогеохимические закономерности динамики пулов и потоков углерода в репрезентативных экосистемах Центральной лесостепи в условиях климатических изменений и антропогенных воздействий" (FZUR-2026-0004).</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The study was carried out within the framework of the state assignment of the Ministry of Science and Higher Education of the Russian Federation № 1025032000060-3-1.5.1 "Biogeochemical patterns of carbon pool and flux dynamics in representative ecosystems of the Central Forest-Steppe under climate change and anthropogenic impacts" (FZUR-2026-0004).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Neaman A., Robinson B., Minkina T.
